Convert between currencies and reveal the true cost of the exchange margin.
Most conversion cost hides in the rate rather than the stated fee, so a provider advertising no commission can still be the most expensive. Comparing the amount received against the mid-market figure exposes the whole cost. Expressing the total as a percentage of the amount is the only way to compare providers whose fees and margins are structured differently.
