An amount in words: dollars and cents written out, for a check, a receipt or a form
Many paper checks have a line where the amount is written in words. A lease, a receipt or a form can ask for it too. And then a word like forty, ninety or eighteen makes the pen stop. Type the amount in numbers, and this page writes it out in English or in Spanish, three ways, each with a button to copy it. If the paper is in Spanish, pick Spanish in the second box.
Good to know
The three lines the page writes
For the amount 1,234.56, the page writes:
- Words, with the cents as a part of 100: One thousand two hundred thirty-four and 56/100. The 56/100 says 56 cents out of the 100 in a dollar.
- Words, with dollars and cents: One thousand two hundred thirty-four dollars and fifty-six cents.
- The number alone, when there are no cents. For 850 it is: eight hundred fifty.
In Spanish, the same amount is Mil doscientos treinta y cuatro con 56/100, and Mil doscientos treinta y cuatro dólares con cincuenta y seis centavos.
Examples, worked by hand.
- 850: Eight hundred fifty and 00/100.
- 2,015.08: Two thousand fifteen and 08/100.
- 0.75: Zero and 75/100. Or: Seventy-five cents.
- 1.01: One dollar and one cent.
- 21, in Spanish: Veintiún dólares. The number alone is veintiuno.
- 100 and 101, in Spanish: cien, and ciento uno.
- 1,000,000, in Spanish: Un millón de dólares.
Every time the page is built, a program checks these examples. It also writes out every number from 0 to 99,999 and 3,000 larger made-up ones in both languages, and a second program reads the words back and has to get the number that went in.
Words that make the pen stop
- Forty has no u. Four and fourteen have one.
- Ninety and nineteen keep the e of nine.
- Twenty-one to ninety-nine take a hyphen: thirty-four, fifty-six.
- This page puts no “and” inside the number: one hundred five. Some people write one hundred and five. The page keeps “and” for the cents.
- In Spanish, cien stands alone, and ciento is used when more follows: cien, ciento uno.
- In Spanish, uno becomes un before mil, millones or the thing counted: veintiún mil, un dólar.
- Quinientos, setecientos and novecientos do not look like cinco, siete and nueve.
- Dieciséis, veintidós, veintitrés and veintiséis carry an accent mark.
- Mil, not un mil. And a round million takes de: un millón de dólares.
What this page does not do
- It does not say how to fill in the rest of a check, and it does not know what a bank, a landlord or an office accepts. The place that takes the paper can say how it wants the amount written.
- It does not check that the amount is the right one. It writes the number you type, and it does not move any money.
- It writes dollars and cents only, not other kinds of money.
- It takes amounts up to 999,999,999.99, with no more than two digits for the cents.
- It writes English the way it is common in the United States, and it has one way of writing each number. Other ways exist.
- It keeps nothing. To keep the words, copy them or write them down.
Tools that go with this

- Letters about a medical bill: put it in writing.
- Letters to your landlord: a repair, back rent, your deposit.
- Split the cost: who pays whom.

The tool and the wording around it were written with AI (Claude) for Scarlet Beast (our AI policy). There is no AI inside this tool: it only looks up the word for each part of the number. It has been checked by a program, not yet by people using it for a real check or form, and the Spanish spelling has not been read by a native speaker. It keeps nothing, so it has no line on My data on this device. Also in Spanish: Una cantidad en letras. Found a mistake? Email [email protected].
