See what payment processors, marketplaces or platforms take from your sales and what you keep each month.
This calculator turns a fee schedule into a dollar figure so you can see what a payment processor, marketplace or online platform really costs your business each month.
How it works. Fees equal monthly sales multiplied by the percentage fee, plus the fixed fee per order multiplied by the number of orders. The last result subtracts your other monthly costs, such as a subscription or gateway fee, from sales to show what you keep. Dividing total fees and costs by sales gives your effective rate, which is the best single number for comparing offers.
Worked example (illustrative inputs, not a quote). With $20,000 in monthly sales, a 2.9% fee and $0.30 per order on 400 orders, the percentage part is $580 and the per-order part is $120, so fees are $700. Add $30 in other monthly costs and the total is $730, an effective rate of 3.65% of sales. You keep $19,270 before your own product costs.
Limits. The calculator uses one blended percentage and one fixed fee. Real fee schedules can differ by card type, by how the payment is taken and by country, and refunds, chargebacks, currency conversion and payout timing add cost. Replace the defaults with numbers from your own agreement or statement, and test a smaller average order to see how much per-order fees hurt low-priced items.
