The European Central Bank publishes euro foreign exchange reference rates for 29 currencies at around 16:00 CET on every working day the TARGET system is open, based on a concertation procedure among European central banks around 14:10 CET, and the ECB states these rates are for information purposes only and that using them for transactions is strongly discouraged.
What ecb euro reference exchange rate means
The ECB describes its euro foreign exchange reference rates as usually updated around 16:00 CET each working day (except TARGET closing days), based on the daily concertation procedure between central banks across Europe that normally takes place around 14:10 CET. The ECB reference rate is a daily information snapshot; the exchange-rate margin this site's own margin calculator measures is the gap between a snapshot like this one and the rate a provider actually offers on a transaction.

What is the ECB euro reference rate, and why does the ECB say not to trade on it?: worked example
As of 21 August 2026, the ECB's published euro/US dollar reference rate was 1.1699, meaning one euro was quoted as worth 1.1699 US dollars for that day's reference. Converting €2,000 at that reference rate gives $2,339.80. A bank or card network settling an actual purchase that day would apply its own dealt rate, which can differ from the reference figure once a spread is added.
How to calculate ecb euro reference exchange rate
Multiply a euro amount by the reference rate to express it in US dollars, or divide a dollar amount by the same rate to express it in euros, using the rate published for the specific reference date. Do not reuse a reference rate from a different date for a transaction settled later.

Common mistakes
Do not assume the 16:00 CET reference rate is what a card issuer, remittance service, or bank teller will use for a same-day transaction; do not apply a reference rate published for one working day to a weekend or holiday transaction not covered by that day's concertation procedure.
Where this calculation stops
The ECB's own framework states the rates are for information purposes only. They exclude any provider spread, transfer fee, or cash-handling charge, and the ECB has suspended publication for at least one currency (the Russian rouble) since March 2022, so availability is not guaranteed for every currency.
A second reference-rate conversion, another currency and date
Reference rates are quoted for many currencies beyond the dollar on the same daily page. Suppose the ECB's published euro/Japanese yen reference rate on a given working day is 172.30, meaning one euro was quoted as worth 172.30 yen for that day's reference. Converting a €15,000 hotel deposit into yen at that reference rate: €15,000 times 172.30 is 2,584,500 yen. As with the dollar example, a bank settling an actual same-day transfer would apply its own dealt rate once a spread is added, not this information-only reference figure.
Why the reference rate has no entry on some days
The ECB publishes a new reference rate only on working days when TARGET, the euro-area payment system, is open; on a TARGET closing day such as certain EU-wide holidays, no new rate is concertated and no new figure is published for that date. A calculation that needs a rate for a non-publication date has to use the most recently published business-day rate instead, and should record which date's rate was actually used.
The dispute this guide resolves: why the Russian rouble has no current rate
On the ECB's own euro foreign exchange reference rates page, the euro/Russian rouble reference rate has been suspended, with the final published rate dated March 1, 2022, because the ECB states it could no longer establish a representative rate given trading conditions in that market. A calculation that needs a current EUR/RUB reference rate cannot be completed from this ECB series at all; the page's absence of a rouble figure is a deliberate suspension, not a missing data point to substitute with an old value.
Checking a converted amount by reversing the multiplication
To verify the 2,584,500 yen result, divide it back by the same 172.30 reference rate: 2,584,500 divided by 172.30 returns 15,000.00, confirming the original euro amount. The same check applies to the dollar example already worked above: $2,339.80 divided by the 1.1699 reference rate returns €2,000.00. A reverse calculation that does not return the starting amount signals a transcription error in the rate or the amount, not a rounding artifact, since reference rates are published to four decimal places.
How the ECB series differs from the Fed's H.10 series
Both are official central-bank reference series, but they answer different questions with different mechanics: the ECB publishes euro-based reference rates for a wide currency list on every TARGET working day, while the U.S. Federal Reserve's H.10 release, covered in this site's own H.10 guide, publishes dollar-based noon buying rates for a smaller set of currencies once a week. Reading a Monday-published H.10 figure as if it were a same-day snapshot, or reading the ECB's daily figure as if it only updated weekly, produces a rate for the wrong date in either direction.
How many currencies the ECB reference-rate list actually covers
The ECB's reference-rate page lists 32 actively quoted currencies alongside the suspended Russian rouble, a wider list than the 23 currencies covered by the U.S. Federal Reserve's weekly H.10 release discussed above. A currency present in one official series is not guaranteed to appear in the other, since each central bank chooses its own currency list independently, and a calculation that needs a specific pair should confirm which of the two official series actually publishes it before assuming a reference rate exists at all.
Checking the day-of-week assumption before using a reference rate
Because the ECB publishes on TARGET working days only, a rate labeled for a Friday can still be the most recent published figure used through the following Monday if the intervening weekend has no new concertation. A calculation that treats every calendar day as having its own fresh reference rate will silently reuse Friday's figure for Saturday and Sunday without saying so; recording the actual publication date next to the rate, not just the transaction date, avoids that ambiguity.
A worked EUR/GBP cross-check using the same reference-rate mechanics
The ECB publishes sterling alongside the dollar on the same daily page, so a euro/pound figure can be read directly rather than derived. If the published EUR/GBP reference rate for a given day is 0.8620, converting the same €2,000 used in the dollar example gives €2,000 times 0.8620, or £1,724.00 - a directly quoted rate, unlike the euro/pound cross rate this site's own currency conversion formula guide instead derives by dividing two dollar-based legs.
Source and verification
The European Central Bank publishes the euro foreign exchange reference rates, states their publication timing and concertation method, and states that using them for transaction purposes is strongly discouraged. Read the named source. Verify the source date and the controlling statement, agreement, payroll record, or accounting record before relying on the illustrated result.
