Flat fee or revenue share: when does Substack's 10% get expensive?
Published 2026-06-10 · figures computed from pricing data verified 2026-06-10
Two pricing philosophies
Newsletter platforms charge one of two ways. Revenue share: pay nothing up front, give up a percentage of subscription revenue forever (Substack takes 10%). Flat fee: pay a fixed monthly price, keep everything minus card processing (beehiiv and Ghost both take 0%). Neither is "better" — they're cheap at opposite ends of the revenue curve, and the crossover point is just arithmetic.
The crossover, computed
Hold a 5,000-subscriber list at $10/month per paid subscriber and grow the paid count. Substack is cheaper until roughly $410/month in gross revenue — about 41 paid subscribers. After that, beehiiv's flat $43.08/month (Scale plan, annual billing) wins, and the gap compounds with every new paid subscriber.
At $1,000/month gross: Substack $166/month vs beehiiv $102.08/month. At $2,500/month gross: Substack $415 vs beehiiv $190.58. At $10,000/month gross: Substack $1,660 vs beehiiv $633.08 — a difference of $12,323.04 per year. Ghost's flat-fee math lands in between at most sizes ($346.50/month at the middle scenario); see beehiiv vs Ghost for that head-to-head.
What the percentage hides
A revenue share feels painless because it's deducted before you see the money — but 10% of a growing number is itself a growing number, and unlike a flat fee it never stops growing. The flip side: a flat fee is a real cost when revenue is zero. If you're pre-revenue, the cheapest plan is whatever costs nothing — see how much Substack actually costs for why its $0 floor is genuinely hard to beat early on.
