Pick two currencies and an amount. The reference rate is loaded the moment you open the page.

Which rate we use

We use the European Central Bank reference rate, published every business day around 16:00 CET. It is the mid-market rate with no markup. Banks, exchange offices and card networks add a spread (often 1% to 5%), so what you pay will be a bit higher.

If you already know the rate your bank charges, type it in the Exchange rate field to see the exact amount.

Example

With EUR/USD at 1.08, 100 US dollars buy about 92.59 euros at the reference rate. A card with a 3% foreign transaction fee would charge you about $103 for the same 92.59 euros.

Frequently asked questions
