About this tool

Not sure how to spell 1,250.50 on a check? Type the amount and get it in words instantly, with hyphens, cents and the currency. Switch between American style (one hundred five) and British style (one hundred and five), and use check mode for the classic “and 50/100 dollars”.

When to use it

Writing a check

Banks treat the written amount as the legal one if it differs from the numbers, so it has to be right.

Invoices and contracts

Loan agreements, leases and purchase contracts often spell out amounts to avoid any dispute.

Homework and spelling

Check how to write forty, ninety-nine or one hundred and one, with the right hyphens.

How to use

  1. Type the amount, with a period for cents.
  2. Choose the currency: dollar, pound, euro, rupee…
  3. Pick American or British English, and check mode if you are writing a check.
  4. Copy the result.

How it works

Numbers from twenty-one to ninety-nine take a hyphen. American English writes one hundred five; British English adds “and”: one hundred and five, one thousand and one.

Check mode writes the dollars in words and the cents as a fraction: “One thousand two hundred fifty and 50/100 dollars”.

The conversion runs in your browser: nothing is sent to a server.

Tips for best results

  • On a check, start at the far left of the line and draw a line after the words so nothing can be added.
  • Write “and” only before the cents in American English, never inside the dollar amount.
  • There is no “s” on hundred, thousand or million after a number: two hundred, five million.
  • Need the amount in Spanish, French, German, Portuguese or Indonesian? Just switch the language.

Common problems and fixes

No result appears

The amount contains a letter or two decimal points. Use only digits, commas for thousands and a period for cents.

I see “and” inside the dollar amount

British style is selected. Switch to American English for “one hundred five”.

The cents disappeared

No currency is selected, so only the whole number is written. Pick a currency to include the cents.
