Substack pricing in 2026: free until it isn't, then 10% forever

A free Substack costs $0 at any list size, and that is not a trial. Unlimited subscribers, unlimited posts, unlimited sends, a hosted website, podcast and video hosting: all of it free until the day you turn on paid subscriptions. From that day, Substack takes 10% of gross revenue, Stripe takes its cut on top, and neither ever tapers.

The email pricing guide prices 14 providers the same way, and Substack is the one that breaks the format: there is no plan ladder to transcribe. There are exactly two states, free and revenue-sharing.

The plans, such as they are

Prices checked August 2026 against the Substack pricing page.

The free state is complete, and we will not pretend otherwise. A 50,000-subscriber free newsletter on Substack costs $0 a month while flat-rate tools charge hundreds at that size. You also get full export of your subscriber list and archive at any time, so the lock-in is lower than the fee structure suggests.

The paid state layers three separate fees on every transaction: Substack's 10%, Stripe's 2.9% plus $0.30 per transaction, and a 0.7% Stripe Billing recurring fee. That last one is the quiet one: it rose from 0.5% for creators who enabled payments after July 10, 2024, and the grandfathered 0.5% rate ended June 30, 2025, so by August 2026 effectively every paid publication pays 0.7%.

The math nobody shows

Substack quotes "writers keep 90%," which is true of the platform fee and not of your bank deposit. Here is the full stack at three revenue levels, assuming subscribers on the $5-a-month minimum price with monthly billing, which is the worst case the platform permits and also the most common one:

The fixed $0.30 is why the percentage looks worse than the headline: on a $5 charge it is 6% by itself. Raise the price and the math softens. At $10 a month, total fees per subscriber drop to $1.66 (16.6%), so the $5,000 month costs $830 instead of $980. Sell annual plans at $50 a year and the all-in rate falls to 14.2%, about $710 on the same $5,000 of monthly revenue. The three levers, in order of power: annual billing, higher price, then nothing, because the 10% itself is untouchable.

Now the comparison that matters as you grow. At $5,000 a month of gross revenue, Substack's platform cut alone is $500 a month, every month. Ghost's Publisher plan hosts a 10,000-member paid publication for $88 a month on annual billing, and beehiiv's Scale tier at 10,000 subscribers is $96 a month effective annual, with a 0% take rate on paid subscriptions (Stripe's fees still apply on both). The crossover arrives somewhere in the low thousands of dollars a month, and past it, staying on Substack is a choice to pay five figures a year for the network and the tooling you did not have to build. For some writers the recommendations engine earns that. Run your own number before assuming it does; our comparisons of beehiiv vs Substack and Ghost vs Substack do the arithmetic at more sizes.

Two smaller line items round out the true cost. A custom domain is a one-time $50 per publication. And the minimum paid subscription price is locked at $5 a month, so you cannot price your way under the fixed-fee problem with a $2 tier.

What Substack costs at your list size

Public list prices, August 2026, annual billing where offered. Substack: Substack does not charge by subscriber. A free newsletter costs nothing at any size; the cost is 10 percent of paid subscription revenue plus payment processing. LetterDuck is $50 per domain, flat, unlimited addresses and subscribers.

Every Substack cell reads $0 because list size never prices anything there; only revenue does. This is the honest place to say the reverse comparison out loud: if your newsletter is free and you do not need an inbox or your own domain, Substack costs $0 and LetterDuck costs $600 a year. We are not the budget option for that reader. The flat rate earns its keep when you want the list on a domain you control, replies threading into a shared inbox, sending addresses for the whole team, and no platform between you and your subscribers.

Is Substack worth it?

For a free newsletter, yes, at the literal price of zero. The costs are strategic instead: your archive lives on Substack's domain (unless you pay the one-time $50), your growth routes through their network, and the email tooling is thin. No automations, no sequences, limited segmentation and A/B testing. What you gain is Notes, the app, and the recommendations network, which drive real subscriber acquisition that a standalone tool cannot.

For a paid newsletter under roughly $1,000 a month, still yes. At $500 of monthly revenue the total fee bill is around $98 (at $5/mo pricing). No flat-rate stack undercuts that meaningfully once you price in the paywall and billing infrastructure you would otherwise assemble.

For a paid publication past a few thousand a month, the 10% is now your largest tool bill, and it grows exactly as fast as you do. This is where writers move to Ghost or beehiiv and keep Stripe's fees only. The tradeoff is real: you give up the discovery network and take on your own growth.

For a business that wants email on its own domain, Substack is the wrong shape. It is a publishing platform with email attached, not an email workspace: no team inbox, no reply-from-any-address, and no control over the sending domain your deliverability is built on. Different job, different tool.
