The exchange-rate markup: the cost that never shows up on an invoice
The exchange rate is where most of the cost of international giving hides. Here's how to see it — and keep more of every donated dollar on mission.
You send full value — but a cut quietly disappears in the exchange.
The scenario
The bank had told Thomas there was no conversion fee, so he didn’t think twice. He’s the finance administrator for a mission that sends monthly support to Nairobi, and when he sent ten thousand dollars, he expected the team on the other end to receive the full value in shillings. They didn’t — they got noticeably less than the rate he’d checked that morning.
Nobody had charged him a fee, exactly. Nothing improper had happened. The cost was tucked inside the exchange rate itself: the bank had converted his dollars at a rate a little worse than the real one and kept the difference. It never appeared as a charge. It just appeared as less money arriving on the other side.

The markup you never see
A ~4% markup — the biggest slice of the 6–11% a bank transfer really costs. On $10,000, about $400: invisible, and charged every time.
That gap is the exchange-rate markup: the difference between the true exchange rate and the rate you were actually given. It doesn't appear as a fee. It's baked into the rate itself, which is why a “free” conversion is rarely free.
Mid-market vs. your rate. The the real exchange rate is the real, midpoint exchange rate — the one you'd see on a public rate site. The rate a provider offers you is usually a little worse, and the difference is their margin. Nothing wrong with a provider earning a margin; the issue is when it's hidden inside a “no-fee” conversion.
Why it compounds for missions. A mission organization converts currency constantly — outbound support to field offices, payments to local staff and vendors, emergency disbursements — across many currencies. A small spread, multiplied by a high frequency of conversions, quietly becomes real money.
How to measure it. On the day of a transfer, compare the rate you received to the the real exchange rate for that pair. Multiply the difference by the amount converted. That's the markup cost — the figure no invoice will ever show you.
A mission converting roughly $40,000 a month across five currencies, at an average markup of 4%, is spending about $19,200 a year on the exchange rate alone — money that never reached the field, and never appeared on a fee line.
The takeaway: ask every provider to show you the the real exchange rate and their spread, in writing. Transparency is the entire game here.
