Know what you really keep. Enter a transaction amount and your processor and this shows the fee and your net payout — so a price isn't quietly eaten by processing costs.
A 2.9% + fixed fee sounds small until you run volume or thin margins. On a 10 sale, a 0.30 fixed fee alone is 3% before the percentage. Factor fees into your pricing, and for international payments watch currency-conversion markups, which often cost more than the headline rate. Always check what lands in your account, not the sticker price.
Around 2.9% + a fixed fee per transaction for cards (Stripe, Square), and ~3.49% + fixed for PayPal. International and currency conversion add more.
Negotiate rates at volume, pass small fixed fees into pricing, and for cross-border payments use a service like Payoneer with lower conversion costs.
No — it calculates the processor's percentage and fixed fee. Conversion markups on international payments are extra, and often the bigger cost.
