About the Currency Converter

Exchange rates move constantly, and a converter that's out of date by a few days can be meaningfully wrong for a large amount. This converter pulls live reference rates from the European Central Bank via the Frankfurter API, covering 30 major world currencies.

How It Works

You pick a currency to convert from and a currency to convert to, enter an amount, and the calculator multiplies your amount by the current exchange rate between the two. Rates are fetched fresh for whichever base currency you select and cached for up to an hour to keep the tool fast without serving stale data.

converted amount = amount × (rate of target currency relative to base currency)

Examples

Converting for a trip

Converting $500 USD to EUR at a rate of 0.865 gives about €432.50 - a quick way to estimate spending money before a trip.

Comparing a price in another currency

A product listed at £80 GBP converts to roughly $108 USD at a rate of 1 GBP = 1.35 USD, letting you compare prices across currencies at a glance.

30 major world currencies, covering most everyday conversion needs

Common Mistakes

Assuming a converter's reference rate is exactly what a bank or card will charge
Not accounting for a money transfer service's markup on top of the reference rate
Using a stale, manually-updated exchange rate table instead of a live source

Edge Cases to Watch For

These are reference rates - the actual rate a bank, card network, or money transfer service gives you will include their own markup and fees, so the amount you actually pay or receive will differ somewhat from this calculator's result.
The European Central Bank only publishes updated reference rates once per business day, so intraday market movements aren't reflected until the next daily update.
Some currencies are subject to capital controls or multiple official exchange rates in their home country - the reference rate shown here is the standard market rate, not necessarily any special or restricted rate.

Common Use Cases

Estimating spending money for international travel
Comparing prices listed in a different currency
Checking roughly how much a foreign invoice or purchase costs in your home currency

Frequently asked questions

How current are these exchange rates?

Rates come from the European Central Bank via the Frankfurter API and are cached for up to an hour - the ECB itself only publishes updated reference rates once per business day, so this stays effectively current.

Can I use this for an actual money transfer or trade?

No - these are reference exchange rates for estimation. Banks, card networks, and money transfer services add their own markup and fees on top of the reference rate, so the amount you actually receive or pay will differ from this calculator's result.

Conclusion

For a quick, accurate sense of what an amount in one currency is worth in another, a live reference rate beats a static table every time. Just remember that any actual transaction - a card purchase, a bank transfer - will apply its own rate and fees on top of the reference rate shown here.
