How to use this calculator
Enter your own quoted percentage and fixed fee for each transaction group. Mix mode lets groups differ.
Formula and method
Group fee = transactions×(average ticket×percentage fee + fixed fee). Blended fee rate = total fees/total processed amount.
Worked example
100 transactions of 50 at an illustrative 2.5% plus 0.30 each yield 155 in fees on 5,000 processed.
Assumptions and supported scope
Estimate from average tickets and user-entered rates. Real pricing, minimum charges, taxes and rounding can differ. Zero processed amount has no blended rate.
