Writing Amounts in Words

On a US check, the legal amount is the one written in words. The standard format is the dollars spelled out, the word "and", then the cents as a fraction over 100.

Frequently Asked Questions

How do I write the amount on a check?
Write the dollars in words and the cents as a fraction over 100. For example, $1,234.56 is written "One thousand two hundred thirty-four and 56/100". The calculator formats this for you.
How are cents shown?
Cents are written as a fraction of 100. So 56 cents becomes "56/100" and zero cents becomes "00/100" (often written as "and 00/100" or "and no/100").
Does it handle large numbers?
Yes. It spells out thousands, millions, billions and trillions, e.g. 2,000,000 becomes "two million".
What is the difference between the two results?
The first is the check (currency) format with dollars and cents. The second is the plain number spelled out, reading any decimals digit by digit, e.g. "one thousand two hundred thirty-four point five six".
