How to Write a Check Amount in Words
Updated: June 2026
The “amount in words” line is the part of a check that banks treat as legally binding, so getting it right matters more than the box of digits beside it. This guide walks through the exact format, shows worked examples for whole dollars and odd cents, and points out the small mistakes that get cheques bounced or rejected.

Why the words line matters
Every check has two places to record the amount: a small box where you write figures such as 1,234.56, and a longer line where you spell the same amount out. When the two disagree, almost every bank in the United States, Canada, the UK, India and beyond is required to honour the written words, not the digits. That single rule is the reason the line exists — handwritten words are far harder to alter than a number, so they act as the legal source of truth and a guard against fraud.
Because the words win, a sloppy or ambiguous line can cause real problems. A teller who cannot read your amount, or who reads something different from the figure box, may hold or return the cheque. Writing the amount clearly and in the conventional format keeps the payment moving.
The standard format
The accepted pattern is: the dollar amount in words, then the word “and”, then the cents as a fraction over one hundred. The cents are written as digits — never spelled out — because a fraction like 56/100 is compact and unambiguous. So $1,234.56 becomes:
One thousand two hundred thirty-four and 56/100
The word “Dollars” is usually pre-printed at the end of the line, so you stop right after the fraction. If your check has no printed “Dollars”, add it yourself. Capitalising the first letter is conventional but not required, and many people draw a horizontal line through any leftover space so nothing can be added later.
Worked examples
| Amount | Written on the line |
|---|---|
| $100.00 | One hundred and 00/100 |
| $45.50 | Forty-five and 50/100 |
| $1,234.56 | One thousand two hundred thirty-four and 56/100 |
| $2,000.05 | Two thousand and 05/100 |
| $15,000.00 | Fifteen thousand and 00/100 |
Notice that the compound numbers between 21 and 99 take a hyphen — thirty-four, forty-five — and that whole-dollar amounts still need the 00/100 so no one can squeeze extra cents onto the line.
Handling zero cents and odd amounts
For an exact dollar amount, the safest forms are and 00/100 or and xx/100; both clearly mean “no cents”. Some writers add the word “only” at the end — One hundred and 00/100 only — which is common on Indian and British cheques and makes tampering even harder. For amounts under a dollar, write Zero and 99/100 or simply Ninety-nine cents only. The converter on this site produces the fraction form automatically in Currency mode, so you can paste a clean, consistent line every time.
Common mistakes to avoid
- Spelling out the cents (“fifty-six cents”) instead of using
56/100— the fraction is the banking standard. - Forgetting the hyphen in twenty-one through ninety-nine.
- Leaving blank space after the words, which lets someone add to the amount. Draw a line to fill it.
- Letting the words and the figure box disagree. Always write both from the same number.
- Adding extra “and” words inside large amounts. American style keeps it simple: one thousand two hundred thirty-four, with the single “and” reserved for the cents.
Frequently asked questions
How do you write $1,234.56 on a check?
Write One thousand two hundred thirty-four and 56/100 on the words line, with “Dollars” printed or added at the end.
What do you write for zero cents?
Use and 00/100 or and xx/100. For example One hundred and 00/100 is exactly one hundred dollars.
Should I add the word “only”?
It is optional in the US but common in the UK and India. It signals the end of the amount and helps prevent tampering.
What if the words and numbers disagree?
Banks generally pay the written words, so make sure both match before signing.
