Inputs and measurement conventions
The quantities used on this page are Payment amount, Percentage fee, Fixed fee, Solve for. Start with values for the same situation and read the units attached to each field. The field reference below shows supported choices and numerical limits.
Country, product, currency conversion and dispute fees can add charges. Defaults are illustrative rather than a guaranteed current tariff.
Method and equation
Apply the entered percentage and fixed transaction charge to gross payment and solve the inverse when targeting net receipts.
Stripe Fee Calculator uses the following stated relationship: fee = gross × percentage + fixed; gross for net = (net + fixed) ÷ (1 − percentage). Its assumptions determine which question the answer can resolve.
fee = gross × percentage + fixed; gross for net = (net + fixed) ÷ (1 − percentage)Worked calculation with the starting values
Payment amount: 100; Percentage fee: 2.9; Fixed fee: 0.3; Solve for: Fee from gross charge. These starting values give 3.2 estimated processing fee. The calculation breakdown is Gross charge: 100; Fee: 3.2; Net received: 96.8; Entered rate: 2.9% + 0.3.
At 2.9% + $0.30, a $100 charge has a $3.20 estimated fee.
Reading the answer
The result models a quoted fee schedule without connecting to Stripe or reading an account's negotiated pricing.
Gross charge: 100; Fee: 3.2; Net received: 96.8; Entered rate: 2.9% + 0.3. These intermediate quantities make the stated Stripe Fee Calculator model inspectable; they should be read together with the main answer rather than treated as independent guarantees.
