Checkout fee inputs
Start with revenue, monthly orders, average order value, international card share, refund rate, and chargeback rate. Those inputs explain most provider differences.
Checkout economics
SaaS Checkout Fee Calculator
Estimate the fee impact of a SaaS checkout before choosing a payment provider, merchant of record, checkout flow, or subscription setup.
Provider model matters
A direct processor and merchant of record may both power checkout, but they do not bundle the same work. Compare the operational responsibilities too.
Low-ticket checkout
Cheap monthly plans are sensitive to fixed fees. Model monthly and annual billing before deciding your checkout strategy.
Global checkout
International cards, tax coverage, local payment methods, refunds, and disputes can change the best checkout provider.
Run a checkout scenario
Use the calculator to compare Stripe, Paddle, Lemon Squeezy, and Polar from one input set.
