APP STORE OR WEB CHECKOUT: THE MATH AT 15%

Summary from the TLDR Founders newsletter

Moving a small app's checkout to the web saves less than the headline App Store fee suggests. At Apple's 15% rate, a $9.99 subscription leaves $8.49 in the app versus about $9.33 after Stripe card and billing fees. With equal prices and renewals, losing roughly 9% of buyers erases that gain before extra operating costs. One small-business app in Adapty's review rolled back its test after revenue per paywall viewer fell 9%. Judge a checkout experiment on revenue per viewer through at least one renewal, using your actual fees.
