Do the basic division.
Effective rate is total processing fees divided by card sales for the period. In an illustrative month with $100,000 sales and $2,850 fees, that rate is 2.85%.
Ask what makes up the number.
Markup and other fee findings give the rate context. Estimated savings are estimates based on assumptions, not an offer or a promise.
Do not confuse costs with deposits.
A fee report explains the statement. It does not establish that every expected dollar reached the bank. Deposit matching needs the bank and settlement evidence too.
