Mid-market rate vs. the rate you actually get
The mid-market rate is the midpoint between what banks pay to buy a currency and what they charge to sell it. It's the rate you see on Google or Reuters, but almost nobody — retail or business — actually transacts at it. Banks, card networks, and money-transfer apps add a markup of 0.5% to 4%, plus fixed fees. A 'no-fee' transfer is rarely free; the cost is buried in a worse exchange rate. Always compare the total amount the recipient receives, not the headline fee.
