ECB Exchange Rates

Official euro foreign exchange reference rates, straight from the European Central Bank - the rates tax authorities, auditors and contracts cite. Convert an amount between any two of the currencies the ECB tracks, look up a rate for today or for the day an invoice was raised, pull the whole daily table, chart a rate over time, and read the ECB's own monthly, quarterly and yearly averages for month-end bookkeeping. Rates go back to 1999. No account or API key required.

Compare a rate between two dates

See how far a rate has moved between two dates, as a percentage and as a number. The step to put in front of a condition: alert when a currency has moved more than two per cent since a deal was quoted, or since the start of the quarter. No API key required.

Convert an amount

Convert an amount of money from one currency to another at the European Central Bank's official reference rate - the rate tax authorities, auditors and contracts cite.
