Currency Exchange Cost Calculator
Compare currency exchange fees across methods.
Calculate the true cost of exchanging money at banks, airports, and ATMs abroad.
Currency exchange costs vary significantly by method.
Typical fee structures:
| Method | Spread/Markup | Fixed Fee |
|---|---|---|
| Bank (home country) | 2-4% | $0-15 |
| Airport kiosk | 5-12% | $0-10 |
| Foreign ATM | 1-3% | $3-7 per withdrawal |
| Credit card (abroad) | 0-3% | $0 |
| Online exchange service | 0.5-2% | $0-5 |
True cost formula:
True Cost = Amount × Spread % + Fixed Fee
Effective Rate = Mid-Market Rate × (1 − Spread %)
How to find the mid-market rate: The mid-market rate (also called the interbank rate) is the “real” exchange rate. Any rate worse than this is a markup by the exchange provider.
Tips to save:
- Avoid airport exchanges — worst rates
- Use a no-foreign-transaction-fee credit card
- Withdraw larger amounts at ATMs to reduce per-transaction fees
- Compare rates before your trip
