Write any euro amount in words in English, for a cross-border invoice or a contract — plus the one question this currency raises that no other does.
Check format sets its own capitalisation: banks expect Title Case, so the option is fixed here.
Type a number to see it spelled out. Pick a currency for an amount with cents, or Check to get the line a bank expects.

01 · the short answer
Ten euros and fifty cents. The amount, then the currency, then the cents — the same shape English uses for any money.
For an amount under one euro, the cents stand on their own: "fifty cents". For a whole amount, the cents are dropped entirely: "one thousand two hundred fifty euros". English does not carry a written zero-cents the way an American check line does, because there is no printed line here that needs closing.
That is the whole rule, and it would make for a short page — except that the euro has an argument attached to it that no other currency does.
Writing euros in words matters most on documents that cross a border, and that is also where the two traps on this page live: the plural, and the decimal separator. Neither is a matter of taste, and both change what the reader understands.
02 · the plural
Both are correct, and which one is correct depends on what you are writing. This is not a style preference — it is a genuine split with a documented boundary.
EU legislative acts
100 euro
In EU legislation, "euro" and "cent" are invariable: no "s" in the plural, departing from ordinary English. The founding texts were drafted that way and later acts follow suit.
Everything else
100 euros
Invoices, contracts, journalism, and the EU's own material for the general public: the ordinary English plural, with the "s", for both euros and cents.
The European Commission's own translation guidance is explicit about the split: use the invariable form when amending or referring to legal texts that observe it, and the natural plural everywhere else — especially in documents written for the general public.
So the practical rule is short. Unless you are drafting or amending EU legislation, write euros and cents. The converter above does exactly that, which is the right default for the invoices and contracts most people are writing.

Straight from the converter above, in the plural form you want for anything that is not a legislative act.
| Figure | In words |
|---|---|
| €1.00 | one euro |
| €0.50 | fifty cents |
| €10.50 | ten euros and fifty cents |
| €99.99 | ninety-nine euros and ninety-nine cents |
| €1,250.00 | one thousand two hundred fifty euros |
| €45,600.75 | forty-five thousand six hundred euros and seventy-five cents |
04 · the separator
This is the euro's real trap, and it has nothing to do with grammar. Most of the euro area writes €1.234,56 and means one thousand two hundred thirty-four euros and fifty-six cents. Read with English conventions, that same string is one euro and a fraction — off by a factor of a thousand.
Cross-border invoices are exactly where the two conventions meet, and neither side is doing anything wrong. The document just has to pick one. In an English-language document, use the English convention throughout: a comma for thousands, a point for decimals.
Writing the amount in words as well is the cheapest possible insurance against this, because "one thousand two hundred thirty-four euros" reads the same in every convention there is. That is the same reason the amount is written twice on any instrument that matters.
05 · where it appears
Written-out euro amounts turn up in different places from written-out dollars or pounds, because the euro area largely skipped the cheque. SEPA transfers and cards took over, and several member states retired cheques almost entirely. There is no euro equivalent of the American 45/100 line or the British "only", because there is no shared payment instrument that needed one.
What is left is documents. Contracts state the consideration in words with the figures in brackets. Higher-value invoices repeat the total. Notarial deeds, which are far more central to civil-law practice than to common-law practice, spell amounts out as a matter of course. In every one of those the reason is the familiar one: the written words are what binds if the two versions disagree.
This site also writes euro amounts in Spanish, where the currency word is the same but everything around it — the gender agreement, the long scale, the decimal comma — is not.
06 · mistakes
— €1.234,56 in an English document
+ €1,234.56
Most of the euro area writes the decimal comma, but an English-language document uses the English convention. Mixing the two on the same page is how an amount gets read a thousand times wrong.
— Euro 1,250
+ €1,250 or EUR 1,250
The currency name is lowercase and goes after the figure in running text; the symbol and the ISO code go before it. "Euro 1,250" is neither.
— one thousand two hundred and fifty euro
+ one thousand two hundred fifty euros
Two things at once: the American form drops the connector, and in a document for the general public the plural takes its "s".
— ten euros and fifty cent
+ ten euros and fifty cents
The invariable "cent" belongs to legislative texts. In an invoice or a contract, use the ordinary plural.
— €10.5
+ €10.50
Two decimal places on any money amount. One is ambiguous exactly where it should not be.
07 · questions
Q01
Name the amount, then the currency, then the cents: "ten euros and fifty cents". For an amount under one euro, the cents stand alone: "fifty cents". The converter above produces this form for any figure.
Q02
Both, in different places. EU legislative acts use "euro" and "cent" invariably — "100 euro" — because the founding regulations were drafted that way. Everywhere else, including documents the EU itself writes for the general public, the normal English plural applies: euros and cents. Unless you are amending a legal text that already uses the invariable form, write euros.
Q03
Before the figure in English: €1,250. The ISO code also goes before: EUR 1,250. The written name goes after: 1,250 euros. Several euro-area languages put the symbol after the figure, which is correct in those languages and wrong in English.
Q04
In an English-language document, a point for the decimal and a comma for the thousands: €1,234.56. Most of the euro area does the opposite in its own languages, so this is worth being deliberate about on any cross-border invoice — the same string means two very different amounts under the two conventions.
Q05
No. Like dollar and pound, euro is a common noun and takes no capital in running text: "fifty euros". It is capitalised only where any word would be, at the start of a sentence or in a heading in Title Case.
Q06
Rarely, and in several of them not at all. The euro area moved to SEPA transfers and cards, and the cheque conventions that shaped English and American amount lines have no single counterpart here. When a euro amount is spelled out, it is normally in a contract or an invoice rather than on a payment instrument.
Q07
Words first, figures in brackets: "the sum of Fifty Thousand Euros (€50,000.00)". As with any currency, if the words and the figures disagree, the written words are what the parties are taken to have agreed.
Q08
"Cents" alone is fine once the euro amount is established: "ten euros and fifty cents". "Euro cents" appears where the currency might otherwise be unclear — a document that also quotes dollar amounts, for instance — and is not wrong, only heavier.
Unless you are drafting EU legislation, the ordinary plural is the right one. Keep the English decimal convention on an English document, and write euros in words where it matters — that version reads the same in every convention, which is exactly why contracts and invoices ask for it.
