Calculate the exact fee and net payout for any transaction with a percentage plus fixed fee structure — works with any currency.
Many payment processors and marketplaces charge a percentage of the transaction plus a small fixed amount, such as 2.9% + $0.30, a common structure among payment gateways worldwide.

This tool calculates exactly how much of a transaction amount you'll actually receive after a platform, payment processor, or marketplace deducts its fee — which is typically structured as a percentage of the transaction plus a small fixed amount per transaction.
Most payment processors and online marketplaces don't charge just a flat percentage — they combine a percentage rate with a small fixed fee per transaction. For example, a processor charging "2.9% + $0.30" on a $100 sale takes $2.90 (2.9% of $100) plus an additional $0.30 flat fee, for a total deduction of $3.20, leaving a net payout of $96.80. This combined structure means the effective fee percentage is actually higher on smaller transactions (where the fixed fee makes up a larger share) than on larger ones.
Understanding your exact net payout before setting a price or accepting a payment helps you price products and services accurately, forecast actual take-home revenue, and compare different platforms' fee structures on equal footing. A platform with a lower percentage but higher fixed fee might actually cost you more on small transactions than a platform with a higher percentage but no fixed fee — this calculator lets you check the real numbers for your specific transaction size.
