Is Substack's 10% Cut Quietly Costing You More Than Beehiiv? The Paid-Newsletter Fee Math

Run the actual take-rate math: Substack's 10% plus Stripe versus beehiiv's flat fee, the exact subscriber count where switching pays, and when the discovery network is still worth the cut.

You set the price at $10, the subscriber pays $10, and a chunk of it never reaches your bank account. The headline number is 10%. The real number is higher, because Stripe's fee stacks on top, and at $5 subscriptions the flat $0.30 per charge bites harder than the percentage does. Most operators on Substack have never run the arithmetic past the 10% they were told, so they cannot say whether beehiiv's flat monthly fee would cost them less or more at their exact price and paying-subscriber count.

This is the fee calculator, not the feature comparison. I ran the take-rate math at the two prices that matter for paid newsletters, $5 and $10 per month, across 50, 100, 250, 500, 1,000, and 2,500 paying subscribers, stacked Substack's true all-in cost against beehiiv's tiered flat plan, and found the precise subscriber count where switching turns positive.

This piece answers one question: at your numbers, is the 10% bleeding you.

The 30-second answer: where the Substack 10% stops being cheaper than beehiiv's flat fee

The crossover is $430 per month in gross paid-subscription revenue. That is the point where Substack's 10% platform fee ($43) equals beehiiv's Scale plan ($43/month), the tier that unlocks 0% paid-subscription revenue share. Below that gross, Substack's no-fixed-cost model wins. Above it, every additional dollar of revenue makes beehiiv's flat fee look cheaper, because the 10% keeps scaling while the $43 does not.

In paying-subscriber terms, the breakeven lands at 43 subscribers at $10/month or 86 subscribers at $5/month. Cross that line and you pay Substack more in platform fees than beehiiv charges in flat plan cost. At 500 paying subscribers on a $10 newsletter, staying on Substack costs about $5,484 a year versus switching. The rest of this article shows the work, then names the cases where the spreadsheet is wrong and you should stay put anyway.

How Substack's take rate actually stacks up (10% platform + Stripe's 2.9% + $0.30 + 0.7% recurring = your real cut)

Substack charges a 10% platform fee on all paid subscription revenue and no monthly fee. You pay nothing until subscribers pay you, which is exactly why it is the right call for newsletters that have not turned monetization on yet. Substack's own monetization page puts it plainly: writers keep 90% of revenue minus credit card fees (Substack going-paid page). The 10% is the part everyone quotes. It is not the part that empties your account.

Stripe processes the charge underneath Substack and takes its own cut: roughly 2.9% + $0.30 per transaction, plus a 0.7% recurring-billing fee on subscriptions. Stack it all and a $10/month subscriber nets you about $8.41, not the $9.00 the headline 10% implies, putting the true all-in take in the 16% to 20% range of gross depending on price, with cheaper subscriptions taxed hardest (beehiiv fee breakdown). The flat $0.30 is the quiet killer. On a $5 subscription that thirty cents is 6% of the charge by itself, which is why low-priced newsletters lose a larger percentage than high-priced ones.

beehiiv's flat-fee math: 0% on subscriptions, tiered by list size (and the one place a 20% cut still applies)

beehiiv takes 0% of paid subscription revenue. Stripe's standard 2.9% + $0.30 still applies, because someone has to process the card, but the platform itself keeps none of your subscription money. Pricing is flat and tiered by total list size, not by paying subscribers: the Launch plan is free up to 2,500 subscribers, the Scale plan runs around $43/month and is the tier that switches on paid subscriptions and 0% revenue share, and Max starts at $96/month for larger lists with more sends and seats (beehiiv pricing). The free Launch tier does not include paid subscriptions, so the honest comparison for a monetizing operator is Scale at $43, not free. The real limitation of the flat model is the inverse of its strength: a slow month still costs you $43, where Substack would have charged you 10% of a smaller number. Our full beehiiv review breaks down each tier against actual send and seat limits.

There is exactly one place beehiiv takes a percentage, and it is not your subscriptions. Boosts, its paid acquisition marketplace where other newsletters pay to recommend you, carries a 20% revenue share. A $2.00 Boost CPA nets you $1.60 (sender.net). That 20% applies only to Boosts income, never to the dollars your paying subscribers send you. Conflating the two is the most common error in beehiiv fee writeups: 0% on subscriptions, 20% on Boosts, two separate buckets.

If full ownership matters more than discovery, several other zero-revenue-share options exist, all of them flat-fee like beehiiv. Ghost (Pro) charges flat self-publish pricing and takes 0% revenue share, the trade being that you bring your own audience. Kit (formerly ConvertKit) runs a paid newsletter and tip jar with no revenue share and far heavier automation, which suits sequence-driven monetizers; see how beehiiv compares to Kit (ConvertKit) for creators who want automation. Flodesk charges one flat rate with unlimited subscribers and 0% on its checkout, which favors design-first creators who hate per-subscriber pricing. MailerLite sits at the cheap end with a usable free tier and paid newsletters at no revenue share, a fit if budget matters more than discovery. All sit outside the head-to-head math below, which stays focused on the Substack-versus-beehiiv take-rate question.

The fee math at $5/month: take-rate and monthly cost at 50, 100, 250, 500, 1,000, 2,500 paying subscribers

Here is the apples-to-apples basis, because it is the only fair one. Stripe charges the same 2.9% + $0.30 on both platforms, so that cost cancels out of the comparison. The only structural difference is Substack's 10% platform fee versus beehiiv's flat Scale plan ($43/month). The table below shows what the 10% platform fee alone costs you each month at $5, then the net result of trading it for beehiiv's $43.

Paying subs ($5/mo)	Gross/mo	Substack 10% fee/mo	beehiiv Scale/mo	Net monthly advantage of switching
50	$250	$25	$43	-$18 (stay on Substack)
100	$500	$50	$43	+$7
250	$1,250	$125	$43	+$82
500	$2,500	$250	$43	+$207
1,000	$5,000	$500	$43	+$457
2,500	$12,500	$1,250	$96 (Max)	+$1,154

At 50 paying subscribers the $43 flat fee costs more than the $25 you would lose to the 10%, so Substack wins. By 100 subscribers the lines have crossed, and the advantage compounds: by 1,000 paying subscribers you keep an extra $457 every month. The 2,500 row jumps to the Max plan ($96) because the total list behind 2,500 paying subscribers, at a realistic free-to-paid conversion of about 5%, runs well past 2,500 addresses (Simon Owens conversion benchmark). Even on the pricier tier, switching nets $1,154 a month.

The fee math at $10/month: the same subscriber counts, where the gap widens fast

Double the price and the 10% platform fee doubles with it while beehiiv's flat $43 stays put. That is the entire reason the gap widens: a percentage scales with revenue, a flat fee does not. The crossover arrives earlier, at just 43 paying subscribers, and the annual cost of staying gets large enough to fund a part-time hire.

Paying subs ($10/mo)	Gross/mo	Substack 10% fee/mo	beehiiv Scale/mo	Net monthly advantage of switching
50	$500	$50	$43	+$7
100	$1,000	$100	$43	+$57
250	$2,500	$250	$43	+$207
500	$5,000	$500	$43	+$457
1,000	$10,000	$1,000	$43	+$957
2,500	$25,000	$2,500	$96 (Max)	+$2,404

At $10 the only close row is 50 subscribers, and even there beehiiv edges ahead by $7. From 100 paying subscribers up, the math is not a debate. At 1,000 paying subscribers on a $10 newsletter you hand Substack $1,000 a month, $12,000 a year, for a service whose flat-fee equivalent is $43. For context, the average paid newsletter charged about $11/month as of 2024 (whop newsletter statistics), so the $10 column here is close to the real-world midpoint, not a cherry-picked high price. Most operators running paid subscriptions land in or just below this band, which is exactly where the 10% starts to sting.

The breakeven: the exact paying-subscriber count where switching to beehiiv turns positive

The breakeven formula is one line: switching turns positive when 10% of your monthly gross exceeds beehiiv's flat plan cost. Solve it against the $43 Scale plan and the crossover gross is $430/month, regardless of price point. Translate to paying subscribers and you get two clean thresholds.

If your list is large enough that beehiiv pushes you to the Max plan ($96/month), the breakeven moves to $960/month gross, which is 96 paying subscribers at $10 or 192 at $5. The honest method: pick the beehiiv tier your total list size actually lands on, multiply, compare. For nearly every operator grossing $300 to $10,000 a month, the relevant plan is Scale and the relevant breakeven is the $430 line.

Annualized: what staying on Substack actually costs you per year at each tier

Monthly differences are easy to wave away. The annual figure is the one that changes behavior, because it is the size of a tool budget, a contractor, or a quarter of runway. This is the net amount you keep by switching to beehiiv Scale, after subtracting the $43/month plan, expressed per year.

Scenario	Substack 10% fee/yr	beehiiv plan/yr	Annual cost of staying on Substack
250 subs @ $5/mo	$1,500	$516	$984
500 subs @ $5/mo	$3,000	$516	$2,484
250 subs @ $10/mo	$3,000	$516	$2,484
500 subs @ $10/mo	$6,000	$516	$5,484
1,000 subs @ $10/mo	$12,000	$516	$11,484

A 500-subscriber, $10/month newsletter leaves $5,484 a year on the table by staying on Substack. A 1,000-subscriber one leaves $11,484. Those are not rounding errors. For how subscription cuts sit alongside ad and sponsorship income, see how paid-newsletter revenue actually stacks up across subscriptions, ads, and sponsorships, since the subscription fee is only one input to total take-home.

Payback math: how many months a migration takes to pay for itself

A switch is not free. You move the list, re-point the paid subscriptions, and spend a weekend on setup, call it $300 of your time at a conservative rate. Payback is that cost divided by the monthly advantage, and at any meaningful scale it is measured in weeks, not months.

The real cost of a migration is not money, it is the risk of dropping paid subscribers during the move. That is a checklist problem, not a reason to keep paying 10%. How to move your list and paid subscribers without losing anyone walks the sequence so churn at the handoff does not undercut the payback.

The numbers the spreadsheet misses: discovery, audience portability, and when Substack's 10% is worth paying

A take-rate table prices the fee and none of the things the fee buys. Substack's 10% funds a discovery engine: the app, recommendations, and the network that surfaces your newsletter to readers who never searched for you. If that network drives even a handful of paid conversions a month you would not otherwise get, it has a dollar value the spreadsheet never sees. At a $10 price and a realistic 5% free-to-paid conversion (Simon Owens benchmark), just 200 extra free readers a month from the network convert to 10 paying subscribers, roughly $100/month in gross revenue. That alone more than covers a $43 plan, which is the whole case for the fee while you are still small.

Audience portability cuts the other way. On beehiiv you own the list and the relationship outright; on Substack you are more entangled with the platform's distribution. The value of ownership shows up the day you want to leave, run a different stack, or stop answering to someone else's discovery algorithm, and that optionality is real even though no row in the table captures it. Honest accounting: discovery is a credit to Substack the spreadsheet ignores, portability is a credit to beehiiv the spreadsheet ignores, and both are genuine.

When to stay on Substack and when to switch (a stage-based call, not a blanket one)

The recommendation is conditional on stage, not a slogan. Match yourself to a profile and the call is clear.

Under ~$430/month gross, just starting to monetize: stay on Substack

Zero fixed cost is undefeated at low volume. Below the breakeven, beehiiv's $43 plan would cost you more than the 10% does, and you also get the discovery network for free while you build. Turn paid on, grow past the crossover, then revisit. There is no prize for paying a flat fee before the math supports it.

$430 to ~$2,000/month gross, growing steadily: switch to beehiiv

You are past the breakeven and the advantage compounds monthly. At 250 paying subscribers on $10, switching keeps an extra $207/month and pays back the migration in under two weeks. This is the clearest win in the whole analysis. beehiiv's 0% paid-subscription plan is the switch that stops the 10% bleed without taking a cut of your subscription revenue in return.

$2,000/month gross and up, established: switch, and the only question is which tier

At this scale the annual cost of staying runs into five figures. Move to beehiiv, size the plan to your total list (Scale or Max), and reinvest the saved 10% into acquisition. If your growth still leans hard on Substack's network, build your own acquisition first, then move; do not torch a working channel to save a fee. Before you commit, scan the wider field of Substack alternatives.

Frequently asked questions

What is Substack's real take rate once Stripe is included?

The headline is 10%, but Stripe's 2.9% + $0.30 per transaction plus a 0.7% recurring-billing fee stacks on top, putting the true all-in take around 16% of gross on a $10 subscription and closer to 20% on a $5 one. A $10/month subscriber nets you about $8.41 rather than $9.00; a $5 subscriber nets about $4.01. The flat $0.30 is why the smaller base gets taxed harder.

Does beehiiv really take 0% of paid subscriptions?

Yes, on its paid plans (Scale and up). beehiiv keeps none of your subscription revenue; only Stripe's standard 2.9% + $0.30 applies, the same processing fee you pay on any platform. The one 20% revenue share beehiiv charges applies solely to Boosts, its paid acquisition marketplace, never to the dollars your paying subscribers send you.

At what subscriber count does switching to beehiiv pay off?

The breakeven is 43 paying subscribers at $10/month or 86 at $5/month, both of which equal $430/month in gross revenue, the point where Substack's 10% fee matches beehiiv's $43 Scale plan. Below that, Substack's zero fixed cost wins. Above it, beehiiv's flat fee wins and the advantage grows with every subscriber.

How long does a migration take to pay for itself?

Past the breakeven, weeks. A 500-subscriber, $10/month newsletter saves about $457/month by switching, paying back a $300 migration effort in under three weeks. At 1,000 subscribers the payback is roughly ten days. The financial cost of moving is trivial; the only real risk is dropping paid subscribers during the handoff, which a migration checklist prevents.

When should I stay on Substack despite the 10%?

Stay if you gross under roughly $430/month, since the flat fee would cost more than the percentage at that volume. Also stay, temporarily, if Substack's discovery network is your main source of paid conversions and you have no replacement acquisition channel yet. In that case the 10% is buying growth, not just charging you. Build your own acquisition, then switch.

Next steps

Run your own numbers in thirty seconds: take your gross monthly paid revenue and multiply by 0.10. If that figure beats $43, you are past the breakeven and Substack is costing you more than beehiiv's flat fee, every month, with the gap widening as you grow. If it is under $43, stay put and revisit when you cross the line. The decision is arithmetic, not preference, once you have your actual numbers in front of you.

If the math points to a switch and your acquisition does not depend on Substack's discovery, beehiiv is the 0% paid-subscription platform this analysis recommends moving to, conditional on your stage. Compare it against the rest of the field first in our best email marketing platforms hub, and if automation depth matters more than discovery, weigh beehiiv against Kit (ConvertKit) before you commit.
