The true cost of changing money rarely comes from the visible service fee alone. This currency exchange fee calculator shows what the rate margin and any fixed fee cost you together, along with the real effective cost percentage.
How the calculator works and what it’s for▾
How the cost is calculated
The margin cost is your amount multiplied by the rate margin. For example, on $1,000 with a 2% margin, the margin costs $20.
The total cost is the margin cost plus the fixed service fee. The effective cost % shows what share of the whole exchange goes to fees once both parts are combined.
What you enter and what you get
You enter the amount to exchange, the rate margin as a percentage, and any fixed service fee in dollars.
You get the margin cost, the fixed fee, their combined total, and the effective cost percentage, which makes comparing different offers easy.
When it helps
It is handy when buying travel money, shopping on foreign sites, sending money abroad, or deciding whether to exchange at a bank, a bureau, or through an app.
On small amounts the fixed fee weighs most, while on large amounts the rate margin determines the total cost.
Good to know
"No commission" often means a hidden rate margin, so a cost still exists even when no separate fee is shown.
Compare the rate you are offered against the mid-market rate to reveal the true margin rather than just the advertised price.
