Percentage plus per-order fees
Card networks, marketplaces, and payout processors often charge a percentage of the transaction plus a fixed amount per order. This page adds those two parts, then subtracts the total from the transaction amount. The default 2.9% and $0.30 are a common card-processing illustration; enter the rates from your contract.
Percentage fee = transaction total × fee rate
Fixed-fee total = fixed fee per order × number of orders
Total fee = percentage fee + fixed-fee total
Net proceeds = transaction total − total fee
Effective fee rate = total fee ÷ transaction total
Fixed-fee total = fixed fee per order × number of orders
Total fee = percentage fee + fixed-fee total
Net proceeds = transaction total − total fee
Effective fee rate = total fee ÷ transaction total
Example
$10,000 across 100 orders at 2.9% plus $0.30 is $290 of percentage fees and $30 of fixed fees. Total fees are $320, the effective rate is 3.2%, and estimated net proceeds are $9,680.
What the bill can still include
Tiered rates, minimums, tax, refunds, cross-border charges, FX, shipping, ads, and promotions sit outside this model. Use the processor statement for the amount actually withheld.
