Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
When can I use the average transaction amount (same currency) result?
Transactions share an average amount. Refund, chargeback, instalment and different card tariffs are excluded; enter your contract values. All monetary inputs must use the same currency; currency conversion, tax and automatic fees are excluded. The source explains percentage and fixed transaction fees; the period subscription is a separate user-entered cost here, not a published tariff.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
