How it works
Effective amount = principal × mid-market rate × (1 − fee%)Frequently Asked Questions
How do currency conversion fees work?
Banks and card networks often quote a rate slightly worse than the true 'mid-market' rate, pocketing the difference as a hidden markup — even when they advertise 'no fees.' A 3% markup on a $2,000 transfer costs $60 you might never see itemized.
What is the mid-market exchange rate?
The real, no-markup exchange rate you see on financial data sites like Google or Reuters — the rate banks trade at with each other, before adding their margin for retail customers.
How can I avoid high currency conversion fees?
Compare the rate you're offered against the mid-market rate for the same currency pair; specialist transfer services and some cards often beat traditional banks by charging closer to the true mid-market rate.
