What the result shows

The estimated yearly cost of percentage fees, per-order fees, refund handling, and chargebacks at your current sales volume.

How it is calculated

Apply each processor rate to its share of sales and orders. Add refund handling and chargeback costs, then multiply the monthly total by 12.

How to use it

Compare the effective cost with recent processor statements. If the estimate does not match, check the order mix, refund charges, and rate tiers before comparing plans.

What this result leaves out

Rates can vary by card type, payment method, country, currency, and plan. Foreign-card fees, currency conversion, failed-payment fees, and other plan-specific charges are not included.
