Platform pricing pages lead with the monthly fee, but your income is decided by the whole stack: monthly fee, platform cut, per-sale charges, and card processing. Enter your price and volume and this shows the only number that matters, what actually lands with you, on every major platform at once.

Card processing is modelled at 2.9% + $0.30 where a platform bills it separately. Subscription platforms are shown at monthly-billing prices; every one of them discounts annual billing. Skillshare is excluded because it pays from a royalty pool by minutes watched, so there is no per-sale figure to compare.
Competitor fees verified July 2026 against published pricing: Gumroad, Udemy, Teachable, Podia, Thinkific, Kajabi. Platforms change fees; check before you commit.
For each platform, the calculator takes your price, removes the platform's percentage cut, any fixed per-sale fee, and card processing where the platform bills it separately. That gives net revenue per sale. Multiply by your monthly sales, subtract the platform's monthly subscription, and you have your real monthly take-home.
monthly net = (price − platform % − per-sale fee − card processing) × sales − monthly fee
A worked example at $49: Kajabi's Basic plan nets $47.28 per sale, but costs $179 a month before you sell anything, so the first 4 sales of every month go to the software. Lesso nets $41.65 per sale with no monthly fee, so sale one is yours. At this price the two cross at roughly 32 sales a month; below that line the subscription is costing you money, above it the maths starts to favour the flat fee. That crossover is exactly what the calculator finds for your numbers.
Monthly fees are paid whether you sell or not; they punish small and irregular sellers. Percentage fees scale with revenue; they cost more in absolute terms as you grow, but they can never put you underwater. Fixed per-sale fees ($0.50 here, $1 there) look trivial and quietly eat low-priced products. Processing is charged by almost everyone on top of everything else; the honest comparison always includes it, which is why this calculator does.
It depends entirely on your volume. At low or unpredictable sales, platforms with no monthly fee (Lesso, Gumroad) always win, because you owe nothing in a month where nothing sells. At high volume, a flat monthly subscription amortises away and 0%-transaction-fee plans can pull ahead on per-sale margin. The calculator ranks all of them for your exact price and volume, which is the only comparison that means anything.
Udemy is a marketplace, not software you rent. On organic marketplace sales instructors keep 37%, and in exchange Udemy supplies the buyers. If a student buys through your own coupon or referral link instead, you keep 97%. The practical rule: Udemy economics reward creators with no audience, and punish creators who already have one.
Yes. Where a platform bills card processing separately, the calculator models it at 2.9% + $0.30 per sale. Lesso absorbs processing inside its 15% platform share, so the 85% you keep is calculated on the full sale price with nothing else taken out.
Every figure was checked against the platform's published pricing in July 2026, and the sources are linked under the calculator. Platforms change pricing, sometimes dramatically (Teachable removed its free plan, Kajabi restructured its tiers), so confirm on the platform's own page before you commit.
No monthly fee, ever. Lesso takes 15% of each sale and pays Stripe's processing fees out of that share, so you keep a flat 85% of every payment. The percentage is the whole business model; there is no plan ladder to climb.
