Credit Card Fee Calculator

Use monthly card sales, average ticket size, and current fee assumptions to estimate annual processing costs.

To estimate credit card processing fees, multiply monthly card sales by the percentage fee, add the per-transaction fee for each sale, then include any monthly fixed fees. Your effective rate is total monthly fees divided by monthly card sales.
