Per-sale fee math
Useful when you just want to answer “what fee comes out of this transaction?” before you move on to the bigger pricing question.
Transaction fee calculator
How much does a transaction fee take from one sale?
Start with the simple fee question, then pressure-test the real payout. Use the same sale to see the processor fee alone and what you keep after taxes, discounts, partner payouts, refunds, and product cost.
- See the fee on one transaction without guessing from processor docs.
- Compare the transaction fee to the rest of your margin leaks.
- Open the same sale in the full calculator and edit the percentage or fixed fee.
Worked example
A $49 sale loses $1.72 to the transaction fee.
On a plain $49 sale with no coupon, VAT, partner payout, refund reserve, or product cost, a 2.9% + $0.30 processing fee takes $1.72. You keep $47.28 before anything else comes out.
Quick answer
The processor fee alone is $1.72. You keep $47.28.
That is the processor fee alone. The full calculator shows what happens after taxes, discounts, partner payouts, refunds, and product cost too.

What this transaction fee calculator page helps with
Real payout math
The transaction fee is rarely the whole story. The real payout changes again when taxes, discounts, partner payouts, refunds, and product cost hit the same sale.
