Substack Fees 2026: What You Actually Keep

The Short Answer: You Keep About 83 Cents of Every $10

If you turn on paid subscriptions on Substack in 2026, you do not pay a monthly platform fee. Instead, Substack takes 10% of every paid subscription payment, and Stripe takes its processing fees on top: 2.9% plus $0.30 per card payment, plus a 0.7% recurring-billing fee. Substack’s own help center confirms the 10% platform cut and Stripe’s card fees. Add it up and a $10 monthly subscription costs you $1.66 in fees. You keep $8.34.

That is the number most “Substack is free” summaries leave out. Substack really is free to publish on — unlimited subscribers, unlimited sends, no monthly bill — but the moment a reader pays you, three separate charges hit the same payment. None of them is hidden, exactly. They are just listed in different places, and the 10% headline is the only one most writers remember.

I have watched too many writers price a newsletter at $5 a month, do the math as “10% off, so I keep $4.50,” and then wonder why the payout looks smaller. At $5, the fixed $0.30 fee does real damage. At $500 a month in revenue, the percentage does. Both effects are worth understanding before you pick a price, because price is the one lever you control completely.

This article works through the full fee stack with real numbers, compares Substack with flat-fee platforms at several revenue levels, and covers the second income lane Substack opened in June 2026: its native sponsorship program. Everything below was checked against Substack’s help pages and current fee coverage in October 2026. Fees change, so treat the tables as a snapshot and re-check the help center before you launch.

The Three Charges on Every Paid Subscription

Here is the full stack, in plain English:

A few details matter here. First, the 10% applies to subscription revenue only. Free subscribers cost you nothing. Second, the $0.30 is per payment, not per subscriber per month in some abstract sense — so a reader on a monthly plan triggers twelve $0.30 charges a year, while a reader on an annual plan triggers one. That is why annual plans look better in the payout column even though they bring in less total cash per reader (more on that below). Third, a custom domain costs a one-time $50 if you want one. It is optional, and it does not change the fee percentages.

One more charge can appear if readers subscribe inside the Substack iOS app: Apple’s in-app purchase fee, which runs 15% to 30%. Substack handles this by charging app subscribers a higher price by default, so the writer’s cut is protected in most cases — but it is worth knowing that an iOS subscriber is not paying the same sticker price as a web subscriber. If you ever compare your subscriber counts with your revenue and the numbers look off, app pricing is a likely suspect.

What You Keep at Each Price Point

The percentage looks modest until you run it at the prices writers actually charge. Here is the per-payment math, using the full 13.6% + $0.30 stack:

Two patterns jump out. First, low prices hurt disproportionately. At $5, you lose nearly a fifth of the payment; at $20, you lose about a seventh. The fixed $0.30 is the reason. If you are tempted to price at $3 or $4 to “make it easy” for readers, run this table first — you would keep roughly $2.30 of a $3 payment, and you would need a lot of subscribers to make that worthwhile.

Second, annual plans keep a bigger share per dollar because the $0.30 hits once instead of twelve times. A $10-a-month reader who stays all twelve months pays $120 and leaves you $100.08. A $100 annual reader pays $100 and leaves you $86.10. Monthly wins on total cash if the reader stays; annual wins on retention, cash up front, and fee efficiency. Most successful newsletters offer both and let readers choose, which is the right call — you are not picking a winner, you are giving two kinds of readers what each prefers.

What the Fees Cost at Real Revenue Levels

Per-payment math is useful, but writers budget monthly. Here is what the stack costs at four revenue levels, assuming $10 monthly subscriptions (so the subscriber counts are clean):

Read that last row twice. At $10,000 a month, Substack and Stripe together take $1,660 a month — nearly $20,000 a year. That is not a complaint; it is the deal you signed up for, and for many writers the discovery, recommendations, and app distribution Substack provides are worth it. But it is also the point where flat-fee platforms start to look very different, and you should know exactly where that line sits rather than feeling it vaguely.

When a Flat-Fee Platform Beats Substack

Flat-fee platforms (beehiiv, Ghost, Kit, and similar tools) charge a monthly price and take little or no percentage of your subscription revenue. You still pay Stripe processing on both sides, so processing mostly cancels out of the comparison. The real comparison is Substack’s 10% platform fee against the flat monthly price.

The break-even math is simple: divide the flat monthly price by 10%.

So a writer earning $500 a month pays Substack $50 in platform fees — cheaper than a $99 flat plan, roughly a wash against a $49 plan. A writer earning $5,000 a month pays Substack $500 in platform fees, which is five times a $99 plan. The gap only grows from there.

That does not mean everyone above $990 should leave. This is where honest trade-offs come in, and they cut both ways:

What Substack gives you that flat platforms do not, or do less well: built-in discovery through recommendations, the Substack app and Notes, category leaderboards, and a reader network where subscribers find you without you paying for ads. Writers who get a large share of paid subscribers from recommendations are, in effect, paying the 10% partly as a distribution fee. If you moved to a flat platform, you would need to replace that discovery yourself, and that costs time or ad money.

What flat platforms give you: predictable costs, more control over branding and email delivery, and tools Substack does not prioritize, like advanced automation, course-style products, or an ad network. If most of your subscribers come from your own website, social following, or email list — not from Substack’s network — the 10% buys you less, and the flat fee wins sooner.

My practical rule: if you are under $500 a month, stay and grow; the fee is small and the distribution is worth it. Between $500 and $2,000, run the break-even table with your actual subscriber sources, not just your revenue. Above $2,000, price out a flat platform seriously, and weigh what share of your new subscribers arrived via Substack recommendations in the last three months. If that share is under a quarter, the move probably pays for itself.

One warning about moving: migrating a list is easy (subscriber CSV export), but migrating paid billing is not. Readers usually have to re-subscribe on the new platform, and some will not. That friction is a real cost of switching, and it is a good reason to get the fee math right before you turn on payments rather than after you have 500 paying readers locked into one billing system.

The Second Income Lane: Substack Sponsorships

In June 2026, Substack launched the first phase of its native sponsorship program, and this changes the fee conversation in an important way: sponsorships are a second revenue lane that does not carry the 10% subscription cut.

Here is how it works, as of October 2026:

• Eligibility: Creator Kits — the media kit you build inside your Substack dashboard — are available to Bestseller publications and publications with at least 100 paid subscribers. You will see a Sponsorships tab in your dashboard once you qualify.
• The kit: You build a Creator Kit describing your audience, voice, and the formats you will run, and you can set a minimum budget plus a private list of brands you would turn down. Kits are not public.
• The brands: The June 2026 launch named seven inaugural partners — Yahoo Scout, Whatnot, Granola, Balenciaga, T-Mobile, Polymarket, and Uber — with Substack saying the partners were putting millions of dollars into creators on the platform. In October 2026, Substack added formats that let brands pay to open paywalled posts to wider audiences.
• The cut: Coverage of the program reports that Substack takes no percentage of the brand deal itself — the sponsorship desk is a matchmaking and paperwork service, not a revenue share. Treat that as the reported position rather than a guarantee, and read the terms for any deal you accept.

The honest catch is the threshold. At a typical 1% to 2% free-to-paid conversion rate, reaching 100 paid subscribers takes roughly 5,000 to 10,000 free subscribers. A newsletter with 8,000 free readers and 50 paid readers does not qualify, no matter how good the writing is. If you are heading toward 100 paid subscribers anyway, the sponsorship lane is a real reason to switch a small paid tier on sooner rather than later. If you are far below it, sponsors are a later problem — build the paid base first, and do not plan your budget around sponsorships you cannot access yet.

Outside the program, writers still find sponsors the old-fashioned way: direct outreach to brands, or marketplaces like Paved. Those routes have no subscriber threshold, but they do take your time. The native program’s value is that Substack does the outreach and paperwork; your job is to keep the audience and the editorial standards that make brands want in.

The Smaller Costs Writers Forget

Three more items regularly surprise new Substack writers:

1. Substack Boost discounts. If you turn on Boost, Substack may offer engaged free readers a discount (20% for a year by default) to convert them. That is a real tool — a discounted subscriber beats a free reader — but a 20% discount on a $10 plan means you are collecting $8 before fees, not $10. Decide deliberately whether Boost is on, and check what discount it is offering.

2. Taxes are on top. The fee math above is what Substack and Stripe take. Income tax on what you keep is separate, and if you earn enough, you may owe quarterly estimated tax in the US. Set aside a percentage of payouts as you go; the first tax bill after a good year is the most common nasty surprise in creator income.

3. Founding tiers and pledges. Substack lets readers pay extra through founding tiers or pledges. The same 10% plus Stripe fees apply to those payments. A $250 founding subscription still loses 13.6% plus $0.30, which is $34.30 in fees. Founding tiers are generous, but they are not fee-free.

A Pre-Launch Checklist

Before you flip on paid subscriptions, run through this list. It takes ten minutes and saves the most common regrets:

1. Pick your price from the take-home table, not the sticker price. If you want to keep roughly $8 per reader per month, price at $10, not $8.
2. Offer monthly and annual. Monthly maximizes cash from loyal readers; annual locks in commitment and cuts fee drag. Offer both.
3. Decide on Boost deliberately. Know the discount it will offer before it offers it for you.
4. Decide on a custom domain now or never. The $50 is trivial, but changing domains later confuses subscribers. If branding matters to you, buy it before launch.
5. Know your break-even revenue. Write down the flat-platform price you would compare against and the revenue level where it wins. Revisit that number every quarter.
6. Set aside tax money from the first payout. Do not wait until the year ends.
7. Track where paid subscribers come from. Recommendations versus your own channels is the single most important input to the stay-or-move decision. You cannot make that call later without this data.

The Bottom Line

Substack’s fee structure is fair, but it is not the “free” that the headline suggests. You pay 10% to Substack and roughly 3.6% plus $0.30 to Stripe on every payment, for a total of 13.6% plus $0.30. At $10 a month, you keep $8.34. At $5,000 a month in subscription revenue, you keep $4,170 and pay $830 in fees. The platform earns its cut while it is bringing you readers; it stops earning it when your audience is mostly your own and the percentage dwarfs any flat fee.

Price with the full stack in mind, watch the break-even point, and treat the sponsorship program as a bonus lane that opens at 100 paid subscribers — not as a reason to delay the paid tier that gets you there.

Frequently Asked Questions

How much does Substack take from each subscription?

Substack takes 10% of each paid subscription payment. Stripe adds 2.9% plus $0.30 per card payment and a 0.7% recurring-billing fee, so the total cost is 13.6% plus $0.30 per payment. On a $10 monthly subscription, you keep $8.34.

Is Substack really free to start?

Yes, for publishing. You can publish and send to unlimited subscribers at no cost. Fees only begin when a reader pays for a paid subscription. A custom domain is an optional one-time $50 charge.

At what revenue does a flat-fee platform become cheaper than Substack?

Divide the flat platform’s monthly price by 10%. Against a $99-per-month platform, Substack’s 10% platform fee equals $99 at $990 per month in subscription revenue. Above that level, the flat platform costs less in platform fees, though Stripe processing applies on both sides and Substack’s distribution value may still justify staying.

What is Substack’s sponsorship program and who qualifies?

Launched in June 2026, the native sponsorship program lets qualifying writers build a Creator Kit and get matched with brands. Creator Kits are available to Bestseller publications and publications with at least 100 paid subscribers. Writers set a minimum budget and can list brands they will not work with.

Do annual subscriptions save on fees compared with monthly?

Yes, slightly. The $0.30 Stripe fixed fee is charged once per annual payment instead of twelve times for monthly payments. A $100 annual subscription leaves you $86.10 after fees, while twelve $10 monthly payments leave you $100.08 in total — monthly brings in more cash if the reader stays all year, but annual locks in the commitment and reduces fee drag.

Does Substack charge fees on free subscribers?

No. Free subscribers cost nothing. Substack only takes its 10% when a reader pays for a paid subscription, and Stripe fees only apply to actual payments.
