Substack is the easiest way in the world to start charging money for writing. That is the whole pitch, and it is true. You can go from nothing to a live paid publication with a card-processing account in an afternoon, at no cash cost, with no contract negotiation and no technical work.
It is also why the model is so badly understood. The ease of setup has nothing to do with the difficulty of the business. What makes a paid newsletter work is not the publishing tool. It is a very specific piece of arithmetic involving the fee stack, the rate at which paying readers leave, and the number of hours you can sustain indefinitely. Most people who start one never run that arithmetic, and most of them stop within a year.
This page runs it. Every fee, threshold and rule below comes from a source you can click at the bottom, and where a number is my own estimate rather than a published figure, it is labelled as such.
Substack gives you a publishing tool, a mailing list, a website on a subdomain, an app presence, and a payments integration through Stripe. Publishing is free regardless of list size. Fees only start when you switch on paid subscriptions.
Two details matter far more than they appear to.
The minimum prices are fixed by the platform: $5 per month and $50 per year, per Substack's pledge documentation.
Three separate fees come out of every payment, and they behave differently.
Here is what that does to real prices, on a US Stripe account.
The spread between 13.9% and 19.6% is driven almost entirely by the flat $0.30, which is charged once per transaction regardless of size. A monthly plan is charged twelve times a year. An annual plan is charged once. Compare identical gross revenue: $10 a month nets you $100.08 over a year, while a single $120 annual charge nets $103.38. The annual plan hands you $3.30 more per subscriber per year for the same money from the reader, purely because you paid the flat fee once instead of twelve times.
That is the first structural insight of the model, and it is not the one people repeat. Annual billing is not mainly about cash flow. It is about not paying a fixed fee twelve times.
Substack's fee page quotes US Stripe rates. Your actual Stripe fees depend on the country your Stripe account is registered in, and they can be very different. Stripe's UK pricing page lists 1.5% + 20p for standard UK cards, 2.5% + 20p for EEA cards, and 3.15% + 20p for international cards, plus 2% for currency conversion.
A UK-based writer whose audience is mostly American is paying a meaningfully worse rate than the same writer with a British audience, and nothing in the Substack interface tells them so.
Substack offers localised pricing in CAD, GBP, AUD, EUR, USD, BRL, CHF, DKK, MXN, NOK, NZD, SEK and PLN. Its documentation says plainly that with localised pricing enabled "you may incur a slight extra fee on your Stripe transactions as Stripe charges 1% to 2% for currency conversion and settlement", and that Substack rounds converted prices upward to compensate. It also notes that converted prices are refreshed only "roughly every three months based on exchange rate fluctuations". Between refreshes, your effective price in a given currency drifts with the exchange rate.
Substack's refund documentation contains a warning worth memorising: "Publishers should issue all refunds through the Substack Subscribers dashboard. Refunds issued through the Stripe dashboard will include Substack's 10% fee."
The Publisher Agreement backs this up: "all Revenue Share payments are non-refundable." Refund a $100 annual subscriber through the wrong dashboard and you return $100 to the reader while Substack keeps its $10. You are $10 down on a transaction that generated no revenue.
Money moves from reader to Stripe to your bank. Substack states that payments "usually arrive in your bank account within 48 hours of each transaction", though the actual schedule is set by Stripe and new accounts are typically held on a longer initial schedule. There is no Substack-side minimum payout threshold, no invoicing, and no waiting for a monthly cycle.
Nothing is withheld for tax. Every payout is gross. The entire tax liability sits with you and arrives later, which is the single most common cause of a nasty surprise in year two.
You can see earnings in three places: the Stripe dashboard, the Substack earnings page at your publication's stats URL, and the Substack apps. Substack notes that the Stripe view "may include activity from sources other than Substack if you use your Stripe account for multiple projects", which is why both Substack and Stripe recommend a dedicated Stripe account for the publication.
A subscription generates many small charges from the same card, and Stripe's documentation flags a specific consequence: "when an account owner disputes multiple payments within a recurring subscription plan, their bank creates a single dispute for the total amount against one of the charges." A reader who forgot they subscribed and disputes twelve months of $10 charges can produce one $120 dispute, plus the dispute fee, against a single transaction.
Card networks typically allow 120 days to dispute. You get roughly 7 to 21 days to respond, the issuer takes 60 to 75 days to decide, and the full cycle runs two to three months. During that time the funds are held.
The defence is unglamorous and effective: a statement descriptor readers recognise, renewal reminder emails, and a cancellation path that does not require emailing you.
Everything above is arithmetic you can do once. Churn is arithmetic you have to do forever, and it is what actually decides whether a paid newsletter works.
A paid newsletter is a leaky bucket. Every month a fraction of your paying readers leave, some deliberately and some because a card expired. Your income is not the number of people who ever subscribed. It is the number still subscribed this month.
Recurly's published churn benchmarks, updated with July 2026 data, put the Digital Media and Entertainment category at 4.14% total churn, split 2.55% voluntary and 1.59% involuntary, against an all-industry average of 3.60%. Recurly's page does not state unambiguously whether these are monthly or annual rates; the industry convention for consumer subscriptions is monthly, and an annual figure of 4.14% would be implausible for this category, so treat them as monthly.
Take 4.14% a month and compound it. After twelve months, roughly 60% of a cohort remains. You lose about 40% of your paying readers every year and have to replace them just to stand still.
At 500 paid subscribers, that means finding about 21 new paying readers every month, forever, before you grow by one. At 1,000, it is 41 a month. The bigger you get, the bigger the treadmill.
Voluntary and involuntary churn are different problems
Roughly 38% of that churn in the Recurly data is involuntary: expired cards, insufficient funds, issuer declines. Nobody decided to leave. The payment simply failed. This is the cheapest churn to fix and the one solo publishers ignore entirely, because it happens silently inside Stripe.
Voluntary churn is a content and expectation problem. Substack's Retention dashboard surfaces paid cohort analysis at 30 days, 6 months and 12 months, plus a paid churn chart and an unsubscribe reasons list for paid publications. That unsubscribe reason data is the most useful thing on the platform and almost nobody reads it.
The annual renewal cliff
Substack's own documentation warns of "a sharper drop at 1 year as yearly subscriptions hit their renewal date". Annual plans hide churn for twelve months and then present it all at once. A publication that looks healthy in month nine can lose a third of its revenue in month thirteen. If you sell annual plans, your first honest read on retention is roughly fourteen months after launch.
The dormancy rule is a publishing obligation
Substack's refund policy states it will issue a refund if "a publication is dormant", defined as inactive for at least six months for yearly subscribers or at least one month from the date of payment for monthly subscribers. Inactivity means no posts published.
Read that as a contractual publishing cadence. Miss a month with monthly subscribers and Substack will honour refund requests over your head. There is no holiday, no burnout window, and no quiet quarter. This is the clause that ends most paid newsletters, and it is not in any of the launch guides.
Substack also honours refund requests submitted within 7 days of payment unless a subscriber perk has been claimed or you have marked the subscription non-refundable.
Free-to-paid conversion: what is actually known
You will see "5 to 10% of free subscribers convert to paid" quoted everywhere, including in the previous version of this page. Substack does not publish a platform-wide free-to-paid conversion rate. I could not find that figure in any Substack help article, in the Publisher Agreement, on Substack's growth features page, or in any first-party post. It circulates because it circulates.
What can actually be sourced:
- Substack's own growth features page states that "The Substack Network drives 25% of paid subscriptions across the platform" and that readers on Substack are "3x more likely to pay for a subscription to your publication".
- The Reuters Institute's Digital News Report 2026 finds that across its basket of 20 tracked countries, "the percentage of people paying for news stayed roughly the same at 17% (compared to 18% in 2025)", with "10-20% appearing to represent a ceiling in most markets". In the UK the figure is around 10%.
- That report also notes that "in markets like Canada (29%) and the United States (21%) above-average percentages of people pay individuals", which is the specific behaviour a paid newsletter depends on.
So the demand-side ceiling for paying for written journalism is roughly one reader in six across developed markets, and paying an individual rather than an institution is a minority behaviour within that minority.
My estimate, clearly labelled as an estimate: for a general-interest newsletter with an engaged free list, sustained conversion in the 1% to 3% range is a realistic planning assumption. Rates above 5% do occur, but they cluster in publications where the content has a direct commercial payoff for the reader, which is a different business from writing. Plan on 2%, be delighted by 4%, and treat any launch-week spike as a one-off drawdown of goodwill from your existing audience rather than a rate you can repeat.
Discovery and network effects, and where they stop
The genuine advantage Substack has over a self-hosted newsletter is distribution. Recommendations, the app, Notes and the leaderboards move readers between publications.
Substack's own numbers, from its February 2024 post on the recommendations network: "Recommendations, along with the Substack app, powers a network that drives 50% of all new subscriptions and 25% of new paid subscriptions on Substack." The current growth features page states the paid figure as 25% and adds that "more than 25% of subscriptions originate from our apps".
Note the gap. The network supplies half of all new subscriptions but only a quarter of new paid ones. Network-sourced subscribers convert at roughly half the rate of subscribers who came to you directly. That is exactly what you would expect: ticking a recommendation checkbox at the end of someone else's signup flow costs nothing and signals nothing.
Substack's own figures have also moved. An earlier Substack post put the network at "more than 40 percent of all subscriptions across the platform, and 12 percent of paid subscriptions". Two Substack posts, two different paid figures. I have not found a methodology note reconciling them, so treat 12% to 25% as the plausible band for network-driven paid subscriptions and do not build a plan on the top of it.
Leaderboards reward what you already have
Substack runs two leaderboard types per category. Top Bestsellers ranks by Annual Recurring Revenue and updates daily. Rising ranks by recent paid subscription growth and updates every few hours. Country leaderboards exist for the UK, France, Italy, the Netherlands and Spain, with placement determined by your Stripe account country.
Bestseller is a rich-get-richer surface: it ranks by revenue, so it can only ever show you publications that already have revenue. Rising is the only realistic entry point for a new publication, and it rewards a burst of paid signups rather than sustained quality. Category selection is a request, not a right; Substack "reserves the right to adjust inappropriate assignments".
What the network cannot do
Recommendations are reciprocal, which makes them a barter market where the exchange rate is set by list size. A publication with 100,000 subscribers has no reason to recommend one with 400. Substack's own case study on its growth page quotes Lenny Rachitsky saying "78% of new subscribers are now coming from other Substack newsletters recommending my newsletter. And 11% of paid." That is a writer with a 625,000-plus list describing the returns available to a writer with a 625,000-plus list.
The network reallocates readers who are already on Substack. It does not create demand for your subject. If nobody wants to pay for weekly commentary on your topic, a leaderboard will not change that.
Substack Boost: growth that comes out of your margin
Boost is Substack's automated discounting system. Its documentation describes automatic discounts, free trials and offers "at the right moment to maximize your revenue". The upsell email carries "a default 20% discount for one year", and the multiple-subscription discount offers "up to 20% off".
The tell is in the payouts help article, which lists Boost first among reasons "your payouts are lower than you expected", and explains how to switch it off. That framing implies Boost is on unless you turn it off.
Run the numbers on a nominal $10 per month subscription sold at a 20% Boost discount:
- Reader pays $8.00
- Substack 10%: $0.80
- Stripe card: $0.232 + $0.30 = $0.532
- Stripe Billing 0.7%: $0.056
- You receive $6.61
Against a $10 headline price, you are keeping 66%. Whether that is a good trade depends entirely on whether the discounted subscriber would have paid full price. Substack's system optimises for conversion, and conversion and margin are not the same objective.
This also breaks your reporting. Substack has a dedicated help article explaining why its Gross Annualized Revenue differs from Stripe's MRR: "Stripe considers the recurring value of those subscriptions to be their eventual full price rather than their current 33% off price. If the majority of your subscriptions came with discounts, the gap between what Stripe reports and what we report may be particularly large."
Two dashboards, two numbers, neither of which is your bank balance.
Migration and list portability: read this before you launch
Substack's marketing rests on portability, and the Publisher Agreement supports it: "First and foremost, you own what you create", and your readers are described as "a list of subscribers that you control (your 'List')". The disputes article adds that "creators own their payment relationships, in addition to owning your intellectual property and mailing list. This gives you control and freedom to build your business on your own terms and leave Substack at any time if you choose."
That is true for the list. It is materially less true for the revenue.
What you can take:
- A CSV of subscriber email addresses with subscription dates and plan types. Substack confirms "It's not currently possible to export a file with the full names of subscribers."
- Your posts.
- Your Stripe account, which is yours.
What you cannot take:
- The active paid subscriptions themselves, in any practical sense. Turning off payments means using the Danger Zone to "Disconnect Stripe", which Substack states will "Refund and notify all your paid subscribers by email" and "Cancel all paid subscriptions to your newsletter". Substack adds that "the balance you'll need in your Stripe account to successfully refund paying subscribers for subscription time they paid for but won't receive will be automatically calculated for you."
Read that carefully. Leaving means refunding every paying subscriber for unused time, out of your own money, and asking every one of them to re-enter their card details on a new platform. Substack's own import guide describes the same friction from the other direction: imported paid subscribers must be given a trial, and "after the trial ends, they'll be prompted to enter their payment information".
Anyone in the subscription business will tell you what happens to a list when you ask everyone to re-enter a card. You do not get everyone back. My estimate, and it is an estimate because no platform publishes this: expect to lose a substantial minority of your paying base in a platform move, plausibly a quarter to a half depending on how much your readers care.
The two decisions that preserve your optionality
Use a custom domain from day one. It costs $50 once. If you publish on a Substack subdomain for three years, every link, every search result and every citation points at an address you cannot take with you. Substack also states it may reassign an inactive subdomain or handle.
Keep a current export. Download the subscriber CSV regularly and keep it somewhere that is not Substack. The Terms of Use reserve Substack's right "to terminate (or suspend access to) your use of Substack, or your account, for any reason at our discretion".
When the 10% stops being worth it
The fee is proportional; alternatives are flat. Ghost's pricing page shows Ghost(Pro) tiers starting at $18 per month billed yearly and states that it takes no percentage of subscription revenue, with only payment processor fees applying. Beehiiv's pricing page shows a free Launch tier up to 2,500 subscribers and a Scale tier at $43 per month, and states it takes "0% of your paid subscription revenue".
The crossover is straightforward: divide the flat annual cost by 0.10. Ghost's $29 per month tier costs $348 a year, which equals Substack's 10% at $3,480 of gross subscription revenue. Beehiiv's $43 per month tier costs $516 a year, equalling it at $5,160. Above those points, on pure platform cost, Substack is the more expensive option.
Two caveats, both important. Flat-fee tiers step up as your list grows, so the crossover moves with you. And the 10% is buying you the network, which the flat-fee platforms cannot sell you. The honest framing is that Substack's fee is a distribution charge, and the question is whether the network is still supplying meaningful growth at your size. If the Network tab in your stats says it is not, you are paying 10% for hosting.
Tax on subscription revenue
None of this is tax advice. It is a map of the questions you have to answer, with the current figures and where they came from.
Income tax and social contributions
United Kingdom. You must register for Self Assessment as a sole trader if you earn more than £1,000 in a tax year. For the 2026 to 2027 tax year gov.uk gives a Personal Allowance of £12,570, basic rate 20% from £12,571 to £50,270, higher rate 40% from £50,271 to £125,140, and additional rate 45% above that. For self-employed National Insurance, gov.uk gives a Class 2 rate of £3.65 a week for 2026 to 2027 with a Small Profits Threshold of £7,105, and Class 4 at 6% on profits from £12,570 to £50,270 and 2% above £50,270. Subscription income is trading income, and the platform and processing fees are deductible business expenses.
United States. Self-employment tax is 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare, and you must file if net earnings from self-employment were $400 or more. The Social Security portion applies up to the annual taxable maximum, which the Social Security Administration set at $184,500 for 2026. Note that the IRS self-employment tax page still displayed the 2024 figure of $168,600 when I consulted it; use the SSA announcement, not that page.
Form 1099-K. The IRS states that third-party settlement organisations must report "when the total amount of payments you receive for goods or services through the platform exceeds $20,000 in more than 200 transactions". The threshold has moved repeatedly in recent years, so check it each January rather than relying on last year's number. Either way, the IRS is explicit: "No matter the amount of reported payments, if you receive payments for selling goods or services, you must report all income on your tax return." Not receiving a form is not a reason not to declare.
VAT and GST on digital services: the part nobody mentions
This is where paid newsletters catch people out, and it follows directly from being the merchant of record.
For business-to-consumer supplies of digital services, the place of supply is where the consumer is, not where you are. HMRC defines digital services as "e-services which are automatically delivered over the internet, or an electronic network, where there's minimal or no human intervention". An automated paid email subscription sits squarely inside that definition.
If you are UK-established and sell to EU consumers, HMRC's guidance gives you two options and no third: register for the non-Union scheme in one EU member state, or register for VAT in each member state where you supply consumers. There is no de minimis for a non-EU supplier. The obligation begins at the first euro.
If you are EU-established, the European Commission's One Stop Shop site states: "Below this EUR 10 000 threshold, supplies of TBE (telecommunications, broadcasting and electronic) services and distance sales of goods within the EU may remain subject to VAT in the Member State where the taxable person is established." Below €10,000 of combined cross-border B2C sales you can charge home-country VAT. Above it, you charge the customer's country's rate and file through the Union scheme OSS, quarterly.
Domestic UK VAT is separate again. gov.uk gives the registration threshold as £90,000 of taxable turnover on a rolling twelve-month basis, with a forward-looking test if you expect to exceed it in the next 30 days. Most solo newsletters will never approach this. It does not remove the EU obligation, which has no threshold for UK suppliers.
The zero-rate question that is worth real money
Since 1 May 2020 the UK has zero-rated electronic publications, including "books, booklets, brochures, pamphlets, leaflets, newspapers, journals and periodicals - including magazines". A paid written newsletter published on a regular schedule looks a great deal like an electronic periodical.
The exclusion is the part to watch: "If more than half of an e-publication is devoted to advertising, audio or video content, its supply will be standard rated." A Substack that is mainly a podcast, or mainly video, or heavily sponsor-laden, falls outside the zero rate. A Substack that is mainly prose plausibly falls inside it.
There is real tension here between two characterisations of the same product: an electronically supplied service with minimal human intervention, and a zero-rated electronic periodical. The classification changes whether you owe 20% on UK sales, and the answer depends on the specific mix of your publication. If you are approaching a VAT registration threshold anywhere, this is worth an hour of a qualified adviser's time, and potentially a non-statutory clearance from HMRC. Do not guess it from a blog post, including this one.
Practical mechanics
Substack integrates with Stripe Tax. Its documentation says the default tax category is "General - Electronically Supplied Services", that Stripe Tax "monitors your subscriptions so you'll know where and when you need to register", and that Substack "will only collect sales tax in locations where you've added a tax registration". Turning the integration on requires asking Substack support to enable it for your publication. Stripe Tax costs 0.5% per transaction in registered jurisdictions.
The trap: your listed price is tax-inclusive until you register. If you cross a threshold and only then start collecting, every sale before that point had the tax buried inside a price you already spent. The liability comes out of your margin, retrospectively.
United States sales tax. Stripe's documentation notes that nexus can be economic as well as physical, that thresholds differ by state, and that "Stripe only monitors if you've reached an economic nexus tax threshold for sales outside of the region your business is based in". Because you are the merchant of record on Substack rather than a seller on a marketplace, do not assume marketplace facilitator laws shift the collection duty away from you. Check it for your states.
Australia and Canada both operate registration regimes for non-resident suppliers of digital services with their own turnover thresholds. I was not able to retrieve the current thresholds directly from the ATO or CRA while writing this, so I am not printing a number. Both authorities are linked below; confirm the current figure with them.
Consumer subscription law is tightening
United Kingdom. The Digital Markets, Competition and Consumers Act 2024 creates a new subscription contracts regime. The government's consultation response states: "We will legislate when parliamentary time allows and we anticipate that the regime will commence in spring 2027." It has already slipped twice, from spring 2026 to autumn 2026 to spring 2027. When it lands, traders must give clear pre-contract information, send reminder notices before trials and long contracts auto-renew, allow online exit if signup was online, and honour two separate 14-day cooling-off windows with proportionate refunds.
United States. The FTC's amended Negative Option Rule, widely known as the click-to-cancel rule, was vacated in full by the Eighth Circuit on 8 July 2025 in Custom Communications, Inc. v. FTC, on procedural grounds, days before its compliance deadline. The FTC has since restarted the rulemaking. The Restore Online Shoppers' Confidence Act still applies, and state automatic renewal laws still apply. The specific federal rule is gone; the exposure is not.
For a solo publisher this mostly means: make cancellation easy, send renewal reminders, and do not build a business on people forgetting.
Why most paid newsletters do not clear minimum wage
Now the part the launch guides skip.
The UK National Living Wage is £12.71 an hour for workers aged 21 and over from 1 April 2026. The US federal minimum wage is $7.25 an hour, unchanged since 24 July 2009, though many states set considerably higher rates.
A serious paid newsletter is not a weekend activity. Research, writing, editing, subscriber support, refund handling, admin and promotion for a weekly publication of any depth runs to 12 to 20 hours a week for most people. Take 15 hours a week as a mid-point. That is 780 hours a year.
The UK case. 780 hours at £12.71 is £9,914 of gross pay-equivalent, before income tax and National Insurance. A £8 per month subscription paid by UK card nets about £6.82, or £81.84 a year. To reach £9,914 you need about 121 paying subscribers, held continuously, with nothing left over for equipment, software, accountancy or research costs.
The US case. 780 hours at $7.25 is $5,655. A $10 per month subscription nets $8.34, or $100.08 a year, so you need about 57 paying subscribers to clear the federal floor. At the $5 platform minimum, netting $48.24 a year, you need about 118. Against a $17 state minimum wage the same 780 hours costs $13,260, requiring about 133 subscribers at $10 a month.
Those subscriber counts sound achievable. They are not, and here is why.
First, churn. Holding 121 subscribers continuously at roughly 4% monthly churn means acquiring about five new paying readers every single month, indefinitely. Not 121 signups. 121 signups plus about 60 replacements every year after that.
Second, the funnel above it. At an estimated 2% conversion, 121 paying subscribers implies a free list of around 6,000 engaged readers. Building an engaged list of 6,000 from a standing start, for a subject that people will pay for, typically takes years. That build time is unpaid.
Third, discounting. If Boost is on and a chunk of your base is at 20% off, every number above gets worse by roughly a fifth.
Fourth, the hours are not fixed. Publishing weekly with a month of illness or holiday triggers Substack's dormancy refund rule for monthly subscribers. The hours are a floor, not an average.
Substack's own about page states the platform has "5 million paid subscriptions and counting". Various third-party statistics sites quote much higher current figures. I could not verify any number above 5 million from a Substack source, so 5 million is what I am reporting.
Substack does not publish a median, a distribution, or the number of publications sharing those subscriptions. Any "average Substack earns X" figure is therefore constructed by dividing one published number by an unpublished one, and it will be meaningless anyway, because the distribution is extremely right-skewed.
Press Gazette's ranking, published in early January 2025, identified at least 52 newsletters earning $500,000 or more a year, collectively at least $40.2 million. Their methodology is worth understanding because it shows how little is actually visible: they infer revenue from Substack's public subscriber bands, where "hundreds" means more than 100 and "thousands" means more than 1,000, multiplied by the annual price. They state their figures "do not take into account the 10% taken by Substack as payment for the service" and "do not take into account subscription discounts, which are widely used and will cut into the actual revenue earned".
So the only publicly visible earnings data on Substack is (a) a lower bound, (b) before fees and discounts, and (c) structurally limited to publications already large enough to appear in a band. It tells you a great deal about the top of the distribution and literally nothing about the middle.
The Reuters Institute notes individual creators with very large followings, including Heather Cox Richardson with "more than 2.5 million Substack subscribers". That is a total subscriber count, not a paid count and not an income figure. It is also roughly the audience of a national newspaper, held by one person, and it is not a benchmark for anybody.
The honest summary: a small number of paid newsletters are excellent businesses, a modest number are decent second incomes, and the large majority never clear the cost of the hours put into them. Nobody publishes the shape of that distribution, and the platform's incentives do not favour publishing it.
The arithmetic that has to be true before you start
Work backwards, not forwards.
- Decide the annual income you need this to produce. Be specific.
- Divide by the net-of-fees annual value of one subscriber at your intended price. Use the worked examples above, not the headline price.
- That gives your required standing subscriber count.
- Multiply by about 0.4 to get the number of replacement subscribers you must find every year just to stay level.
- Divide the standing count by your conversion assumption, 2% unless you have your own data, to get the free list you need.
- Estimate honestly how long building that list takes, and treat every one of those months as unpaid.
If that calculation produces a number you would not accept as a job offer, the answer is not to work harder on the newsletter. It is to change the price, change the subject, or add a second revenue line that does not depend on subscription volume.
Structural decisions that materially change the outcome
- Price above the minimum. The flat $0.30 per transaction makes the $5 monthly tier the worst-value plan on the platform, at 19.6% effective cost. If your content justifies $8 or $10, charging $5 is not a kindness to readers, it is a transfer to Stripe.
- Push annual plans deliberately. They cut the flat-fee drag from twelve charges to one, and they defer churn. Just remember they also defer your knowledge of churn.
- Own the domain from day one. $50 is the cheapest optionality you will ever buy.
- Fix involuntary churn first. It is roughly 38% of the total in the Recurly benchmark and requires no creative work.
- Decide about Boost consciously. It is a revenue-per-conversion trade, and Substack's payouts documentation names it first among reasons your money is lower than expected.
- Read your unsubscribe reasons. Substack collects them for paid publications and almost nobody looks.
- Separate the Stripe account. Both Substack and Stripe recommend it, and it makes your tax reporting tractable.
- Set aside tax from every payout. Nothing is withheld.
Who should skip this
Be blunt with yourself about all of these.
- Anyone who needs income inside six months. The unpaid list-building phase is the business. There is no version that skips it.
- Anyone who cannot publish on a fixed cadence indefinitely. Substack's dormancy refund rule makes a one-month gap a refund event for monthly subscribers. If your life does not accommodate that, this is the wrong model and a one-off product is a better fit.
- Anyone writing on a subject with no recurring need. Subscriptions are paid for recurring value. A topic that can be exhausted in ten excellent posts should be a book or a course, not a subscription.
- Anyone unwilling to be identifiable. Stripe requires verified identity details, and Substack warns that your support phone number, email and address may appear on receipts, invoices and card statements. A virtual mailbox helps. Full anonymity does not survive taking money.
- Anyone who will not do the admin. Refunds, chargebacks, VAT registration, list hygiene and Self Assessment are the job, not a distraction from it.
- Anyone building an asset to sell. You cannot transfer active paid subscriptions off Substack without refunding and re-acquiring them. The list has value; the recurring revenue is much less portable than it looks.
- Anyone whose paid content would constitute regulated advice. If what sits behind the paywall amounts to regulated financial advice, investment recommendations, legal advice or medical advice in your jurisdiction, charging for it does not exempt you from the relevant regulator. Check before you take money, not after.
- Anyone who only wants to write. The writing is perhaps half the work. The rest is running a small subscription business with international tax exposure.
Where it does work
The model earns its keep in a narrow set of conditions, and they are worth naming because they are the opposite of generic advice.
- The subject has a commercial payoff for the reader, so a $10 monthly charge sits against a benefit the reader can quantify. This is why finance, professional and industry newsletters dominate the visible top of the leaderboards.
- The writer already has an audience somewhere else and is converting it rather than building from zero. This collapses the unpaid phase from years to weeks.
- The content is genuinely hard to obtain elsewhere, through access, expertise or original work. Commentary on freely available news is the most crowded and least defensible category on the platform.
- The newsletter is one revenue line among several, alongside consulting, sponsorship, speaking or a product, so subscription income does not have to carry the whole load alone.
If two or more of those are true for you, the arithmetic in this page can work. If none are, no amount of posting cadence will fix it.
