Currency Converter
A currency converter shows how much one currency is worth in another, based on the current exchange rate. Exchange rates constantly shift based on supply and demand in currency markets, central bank interest rate decisions, inflation, and economic data ā so a rate that applies today may be slightly different tomorrow.
How It Works
This calculator uses the European Central Bank's daily reference rates ā the same benchmark rates used across the eurozone financial system. They reflect the wholesale interbank market, not the rate you would actually get at a bank, currency exchange kiosk, or money transfer service.
Banks and money transfer providers add a margin (spread) on top of the reference rate, typically 1-4%, plus sometimes a flat fee. Always check the actual rate quoted by your bank or provider before completing a transaction ā this tool is for estimation and comparison, not for executing trades.
Cross Rates
Since all rates are quoted against EUR, converting directly between two other currencies (say, US Dollar to Japanese Yen) involves two steps internally: the amount is converted from USD to EUR, then from EUR to JPY. The result is mathematically identical to a direct quote, and is called a cross rate ā standard practice across the foreign exchange market.
Major Currency Pairs
EUR/USD is the most-traded currency pair in the world, followed by USD/JPY and GBP/USD. These pairs tend to have the tightest spreads (smallest difference between buy and sell price) at banks and exchange services because of their high trading volume ā meaning you typically get closer to the true market rate than with less commonly traded currencies.
Currencies from smaller economies or those with capital controls (some Southeast Asian and Middle Eastern currencies) often have wider spreads and more rate variation between providers, since lower trading volume makes it harder for banks to hedge their exposure at a competitive rate.
Rate Volatility
Exchange rates fluctuate based on interest rate differentials between countries (higher rates tend to attract foreign investment, strengthening a currency), inflation expectations, trade balances, and geopolitical events. Central bank policy announcements ā like an interest rate decision ā are among the most common triggers for sharp, short-term currency moves.
This is why a rate you saw yesterday may differ noticeably from today's, even without obvious news ā currency markets trade continuously across global time zones, and small shifts in trader sentiment accumulate throughout the day.

Rates are refreshed from the European Central Bank's daily reference rates, published once per ECB business day (around 16:00 CET), and cached for up to 12 hours on this page.
30 major world currencies including USD, EUR, GBP, JPY, CNY, AUD, CAD, CHF, INR, and BRL. Some smaller or heavily-restricted currencies are not covered by the ECB reference rate data.
No. These are ECB reference rates for informational purposes. Banks, money transfer services, and brokers apply their own spread/margin on top of the interbank rate, so the amount you actually receive or pay will differ.
All rates are quoted against EUR as the base currency. To convert between two other currencies (e.g., USD to GBP), the amount is first converted to EUR, then from EUR to the target currency ā this is called a cross rate.
Exchange rates fluctuate daily based on currency markets, central bank policy, and economic data. The ECB publishes a new reference rate each business day, which this calculator reflects after its cache refreshes.
Exchange rates move based on interest rate differences between countries, inflation expectations, trade flows, and geopolitical events. Central bank policy decisions are especially common triggers for sharp short-term moves, since currency markets react quickly to changes in expected returns between countries.
Major pairs like EUR/USD, USD/JPY, and GBP/USD have the tightest spreads because of high trading volume, so quoted rates tend to be closer to the true market rate. Less commonly traded currencies often carry wider spreads at banks and exchange services, even when the reference rate itself is accurate.
