How much does Substack actually cost?

The fee structure, in one paragraph
Substack charges no platform fee at any list size. Publishing free newsletters costs nothing, forever. The moment you turn on paid subscriptions, Substack takes 10% of revenue, and Stripe takes its cut on top: 2.9% + $0.30 per card transaction, plus a 0.7% recurring-billing fee. The advertised "10%" is really 13–16% of gross once processing is counted — see Substack's fee profile for sources.
What that means in dollars
A newsletter with 100 paid subscribers at $8/month grosses $800/month. Substack's cut plus processing comes to $138.80/month — an effective fee of 17.35% — leaving you $661.20.
Scale that to 500 paid subscribers at $10/month ($5,000/month gross) and the costs scale with you: $830/month in fees, or $9,960 per year. That's the core trade: Substack's model is pay-as-you-earn, which is generous when you're small and expensive when you're not. For comparison, a flat-fee platform like beehiiv costs $338.08/month for that same newsletter — the full comparison is in Substack vs beehiiv.
When Substack is genuinely the cheap option
Below roughly $410/month in paid revenue (about 41 paid subscribers at $10), Substack costs less than beehiiv's cheapest paid plan — $0 in fixed costs beats a flat fee when there's little revenue to take a cut of. If you're pre-revenue or testing whether readers will pay at all, Substack's $0 floor is a real advantage, and no platform we track charges less at that stage.
Past the crossover, every additional paid subscriber widens the gap. Run your own numbers in the calculator — the cheapest platform depends entirely on your list size, paid conversion, and price.
Fine print that changes the math
Annual subscriptions incur one card transaction per year instead of twelve, so a list that skews annual pays meaningfully less in per-transaction fees than our monthly-billing assumption. And Substack's 10% applies only to subscription revenue — there's no fee on free posts, and no charge for using the platform as a website or archive.
