How the calculator works

Multiply monthly collected revenue by the share paid by card to get monthly card volume. Multiply that volume by the effective rate to find current monthly processing cost. Annualized totals assume twelve identical months.

To show processing cost as a share of profit, divide monthly processing cost by the illustrative profit calculated from your entered margin. This is a calculation, not a quote or promised savings.

Get the card volume right

Count completed card sales and deposits paid by card only once. Leave out cash, checks, ACH, financing proceeds and unpaid bookings. Confirm your total against a recent statement.

Compare the full proposals

Include all remaining monthly costs. Use the same payment mix, channels, transaction count and refund activity for each proposal. Check at least three representative statements before deciding.
