Foreign exchange (FX) fees are one of the biggest hidden costs for businesses operating internationally. A seemingly small 3-4% markup can cost you thousands—or even millions—per year.
This comprehensive guide explains how FX fees work, where they hide, and most importantly, how to minimize them to save significant money on international payments.
Foreign exchange fees are charges applied when converting one currency to another. When you send $10,000 USD to a supplier in Europe, someone needs to convert those dollars to euros—and they charge a fee for that service.
The two components:
Let's say you're paying a European supplier €100,000 (approximately $108,000 USD at mid-market rate).
Traditional Bank:
Wise:
Savings: $3,560 per transaction
Annual savings (12 transactions): $42,720
The mid-market rate (also called interbank rate or real exchange rate) is the midpoint between the buy and sell prices of two currencies on global markets.
Where to find it:
This is the "real" rate—the rate banks use when trading with each other. Consumers and businesses rarely get this rate.
What it is: The provider adds a percentage to the mid-market rate.
Example:
How to calculate:
Markup % = ((Mid-market rate - Provider rate) / Mid-market rate) × 100
Typical markups:
What it is: A fixed or percentage-based fee charged per transaction.
Examples:
