How many paid subscribers does it take to cover your platform bill?

The number that decides when charging starts paying

If your platform charges a monthly plan fee, the first paid subscriber doesn't put you in the black — it just makes the hole smaller. The number worth knowing is where that hole closes: the smallest number of paying subscribers at which what you collect covers the plan fee, the platform's cut, and payment processing combined. It's a floor, not a target, but it's the point where a paid newsletter stops costing you money to run.

Take a 2,000-subscriber list charging $10/month. On Buttondown's Standard plan ($29/month), it takes 4 paying subscribers — $40/month of revenue against $31.36/month of cost. beehiiv needs 5 on its Scale plan ($43.08/month), and Ghost (Pro) needs 5 on its Publisher (up to 2,500 members) plan ($46/month). Kit needs the most at 6, on its Creator (up to 3,000 subs) plan at $49.17/month.

Those plan fees assume annual plan billing wherever it's cheaper than paying month to month, which is how our calculator models cost — see annual vs monthly billing for what that choice is worth on its own.

On Substack the answer is one

Substack has no plan fee at any list size, so there's no hole to climb out of. A single subscriber paying $10/month grosses $10 and costs $1.66 in fees — $8.34 left over. You are profitable on subscriber number 1 and every one after it, which is a real advantage and the honest reason a lot of small paid newsletters live there.

The catch is the same mechanism read from the other end: Substack takes 10% of every dollar forever, so the thing that makes it painless at one paid subscriber makes it expensive at a thousand. Its all-in share of gross sits at 16.6% whether you have one paid subscriber or 200. The flat-fee platforms are the mirror image — brutal at the start, where essentially all of your revenue goes to the plan fee, and cheaper the further past breakeven you get. At 200 paid subscribers on that same 2,000-subscriber list, Buttondown costs 7.35% of gross against Substack's 16.6%. The full mechanics are in how much Substack actually costs and flat fee or revenue share.

Your price moves the number more than your list does

Halve the price and you roughly double the breakeven. At $5/month on the same 2,000-subscriber list, Buttondown needs 7, beehiiv 10, Ghost (Pro) 11, and Kit 11 paying subscribers. Push the price to $20/month and it collapses: Buttondown needs 2, beehiiv 3, Ghost (Pro) 3, and Kit 3. The plan fee didn't change in either case — only how much each subscriber contributes toward it. If you're weighing what to charge, that's the same lever examined from the fee side in does your subscription price change what you pay in fees.

List size moves it too, but more gently, because plan fees are sold in brackets rather than per head. On Ghost at 1,000 subscribers, 4 paying subscribers cover the $29/month Publisher (up to 1,000 members) plan; at 25,000 subscribers the plan costs $141/month and it takes 15. Kit shows the same shape with a sharper start: at 1,000 subscribers its Newsletter (Free) plan costs $0/month, so a single paid subscriber is already ahead, while at 25,000 subscribers the Creator (up to 25,000 subs) plan needs 18. A list 25× larger raised the bar by a factor of 3.8 on Ghost — see Ghost vs Kit for the rest of that ladder.

Those deeper numbers use Ghost and Kit because both are verified bracket by bracket to 100,000 subscribers. beehiiv's plan price scales with list size and we've confirmed it directly only to 2,500 subscribers, and Buttondown's published plans stop at 20,000 — so quoting either above those points would mean publishing a number we haven't checked, which this site doesn't do.

Breakeven is a low bar, and that's the point

The striking thing about all of these numbers is how small they are relative to a list. At 2,000 subscribers, Buttondown's breakeven of 4 paying subscribers is 0.2% of the list; Kit's 6 is 0.3%. Even at 25,000 subscribers, Ghost's 15 and Kit's 18 work out to 0.06% and 0.07% of the list. A plan fee that sounds heavy in isolation is usually covered by a fraction of a percent of your readers.

Which means the plan fee is rarely the decision. Once you're past breakeven, what actually separates these platforms is how the cost behaves as revenue grows — a flat fee stops growing while a percentage doesn't, and that crossover is worth far more money than the entry cost. Model your own list and price in the calculator, read the per-subscriber view in what one subscriber costs per month, and if you haven't started charging yet, when a free tier actually ends covers the step before this one.
