Foreign Exchange Fee Calculator

Calculate the total cost of foreign exchange fees on a transaction.

About Foreign Exchange Fee Calculator

Fees stack: a percentage commission, a percentage payment-processing charge and a flat per-transaction fee. Because the flat fee is constant, the effective fee rate is much higher on low-value orders than on high-value ones. On a low-value order the fixed fee alone can exceed the margin, which is why marketplace sellers need a minimum order value rather than a flat margin target.

Formula

Foreign Exchange Fee

Net = sale price − commission − processing fee − fixed fee
