# FX markup

**FX markup** is the margin a provider adds to the real exchange rate when converting currency — a fee built into the rate you're given, on top of (or instead of) any transfer charge you can see.

## How it works

- The provider takes the true rate and shifts it a fraction in its favour.
- You convert at that worse rate; the gap is the provider's cut.
- It shows up as "no fee" or "0% commission" while the margin hides in the rate.

The tell is the difference between the rate you're quoted and the [mid-market rate](/glossary/mid-market-rate/) at the same moment — that gap, expressed as a percentage, is the markup.

## Why it matters

FX markup is the fee businesses most often miss, because there's no line item to spot. A 2% margin on a cross-border payout run doesn't feel like anything, but multiplied across every supplier and seller payment, it's one of the quieter places money leaks. On high-volume conversions it can dwarf the visible fees.

## How Fynex does it

Fynex routes every [cross-border payment](/glossary/cross-border-payment/) to the cheapest rail across SEPA, SWIFT and local schemes, so conversions aren't forced through one padded rate. Keeping more of the money chain inside the business is the point — see [where your business is losing money](/blog/where-is-your-business-losing-money/) and [payouts](/features/payouts/).
