How to use this calculator
What to enter
Enter or select the following as requested: Currency; Purchase price; BNPL fee/interest rate (%); Fixed BNPL fee; Number of payments. Follow the units, valid ranges, examples, and options displayed beside each field.
What the result means
The payment result estimates processing charges, conversion costs, installment amounts, or the net settlement from the transaction amounts and fee rules entered. Check whether percentage and fixed fees both apply, whether taxes are charged on fees, and whether the provider uses a different rate for international, refunded, or disputed transactions.
When to use it
Use this to compare payment methods or estimate the amount charged, received, or retained after fees. Verify current provider terms, currency conversion rates, and tax treatment before quoting prices or reconciling actual payouts.
