How it’s calculated

Converted amount = Amount × (units of the target currency per 1 US dollar ÷ units of the source currency per 1 US dollar). With a markup, you receive Converted amount × (1 − markup). The mid-market rate is the midpoint between buy and sell prices on global currency markets.

Rates are the European Central Bank’s daily reference rates, loaded from the free Frankfurter service. If they can’t be loaded, indicative rates are shown instead. Not financial advice.

How to use the currency converter

  1. Enter the amount you want to convert.
  2. Choose the currency to convert from and to. Use the swap button to reverse them.
  3. Add your bank’s or card’s markup or fee as a percentage to see what you’d actually receive.

The quick conversions show common amounts at a glance, and the table lists what one unit of your currency buys in each of the others.

Where the exchange rates come from

The converter uses the reference rates the European Central Bank publishes every working day, loaded from the free Frankfurter service. They are mid-market rates: the midpoint between the prices at which banks buy and sell currency. They are meant for information, so the rate you get from a bank, card or exchange office will usually be less favorable.

Converted amount = amount × (rate of the target currency ÷ rate of the source currency)
With a markup: you receive the converted amount × (1 − markup)

Example: what a 3% fee costs

Suppose the mid-market rate is 0.86 euros per US dollar (an illustrative figure). Converting $1,000 gives €860.00. With a 3% markup, you would receive about €834.20, so the fee costs you €25.80 on this one exchange.

How to get a better exchange rate

  • Pay in the local currency. When a card terminal or ATM abroad offers to charge you in your home currency, say no; this “dynamic currency conversion” usually comes with a poor rate.
  • Check your card’s foreign transaction fee. Many cards charge one on every purchase abroad; some charge none.
  • Avoid airport and hotel exchange desks, which often have the widest spreads.
  • Compare the total you receive, not just the advertised fee. A “zero commission” service can still use a poor rate.

Frequently asked questions

Are these live exchange rates?

No. They are the European Central Bank’s daily reference rates, which are updated once each working day. Market rates move all the time, so treat the result as a close estimate.

What is the mid-market rate?

It is the midpoint between the buy and sell prices of a currency on global markets. It’s the fairest benchmark for comparing what providers offer.

Why did my bank give me a different rate?

Banks and card networks add a markup to the mid-market rate and may charge separate fees. Enter the markup to see its effect.

Can I use this for business or trading?

It’s designed for everyday estimates such as travel, shopping and transfers. For trading or accounting, use the rates your bank or broker actually applies.

Rates are the European Central Bank’s reference rates for information only. If they can’t be loaded, indicative rates are shown and clearly labeled.
