How to use it
Type the amount you want to convert.
Choose the currency you’re starting with in the “From” box.
Choose the currency you want in the “To” box.
Read the result. Use the swap button if you want to convert in the opposite direction.
How the conversion works
An exchange rate tells you how much of one currency you get for one unit of another. The calculation is a simple multiplication:
Converted amount = amount × exchange rate
To go the other way, divide by the rate instead, or use the inverse rate.
A worked example
The rates below are made up for the sake of the example. They are not live rates.
Suppose 1 euro is worth 1.10 US dollars.
Euros to dollars: 200 × 1.10 = 220, so €200 is $220.
Dollars to euros: 220 ÷ 1.10 = 200, so $220 brings you back to €200.
In practice you’d lose a little on the way, because banks and exchange offices don’t convert at exactly this rate. More on that below.
Why you won’t get exactly this rate at the bank
The rate you see on a converter is usually the mid-market rate, which sits halfway between what traders buy and sell a currency for. Banks, card companies and exchange bureaus rarely offer it. They typically add a margin, charge a fee, or both. So the amount you actually receive is usually a bit lower than the converter shows.
To get the best deal:
Compare the total you’d receive, not just the advertised rate. A “no fee” offer can hide a poor rate.
Avoid airport exchange counters when you can. They tend to be among the most expensive options.
When paying by card abroad, choose to pay in the local currency. If the terminal offers to charge you in your home currency, the rate it uses is often worse.
Check your card’s foreign transaction fees before you travel.
Things that affect exchange rates
Rates change all day. Interest rates, inflation, economic news, political events and plain supply and demand all push a currency up or down. Because the converter uses live rates, the result reflects the market at the moment you use it. If you’re about to make a large transfer or purchase, check the rate again when you actually pay, since it may have moved.
Mistakes worth avoiding
Relying on a figure you noted earlier. The converter updates as the market moves, but a number you wrote down yesterday won’t.
Ignoring fees. The converter shows the value of the money, not what a provider will charge to move it.
Rounding too early. On larger amounts, small differences in the rate add up, so keep the full figure until the end.
Mixing up the direction. Converting from A to B and from B to A use different rates. Check which box is which.
Frequently asked questions
Where do the exchange rates come from?
The converter uses live market rates, which reflect where currencies are trading at the time you use it. They are mid-market rates, so they won’t include the fees or margins that banks and exchange offices add. If you need an exact figure for a transaction, confirm it with your bank or transfer provider.
How often are the rates updated?
The rates are live, so they follow the market as it moves rather than being fixed once a day. Currency markets change constantly, and the figure you see can still differ slightly from the one your provider quotes a moment later.
Can I use this to decide when to exchange my money?
It can show you roughly what an amount is worth, but it can’t predict where a rate is heading. For large exchanges, speak to your bank or a licensed provider.
Why is the amount I received lower than the converter showed?
Because of fees and the margin added by the provider, as explained above.
Does the converter work with every currency?
It covers the currencies listed in the drop-down menus. Some less common currencies, or those with restrictions on trading, may not be available.
