Check Amount in Words

Type the amount. The converter writes it out the way a check expects (“One Thousand Two Hundred Fifty and 50/100 Dollars”) or as plain words with cents. Copy it as typed or in capitals.

How to use the converter

1. Type the amount in figures. You can include a decimal point and up to two digits of cents. Commas are optional.
2. Choose the format. Check style gives the wording used on the amount line of a personal or business check, with the cents as a fraction over 100 and the word “Dollars” at the end. Words only spells out both dollars and cents in plain English.
3. Copy the result, as typed or in capitals, and paste it into your check printing software, invoice template or legal document.

The words update as you type, so you can check them against the figures before you write anything by hand.

How to write the amount on a check

A US check has two places for the amount: the small box on the right for the figures (the “courtesy amount”) and the long line in the middle for the words (the “legal amount”). Write them like this:

• Start the words at the far left of the line so nothing can be added in front.
• Write the dollars in words, then “and”, then the cents as a fraction over 100.
• Finish with “Dollars” if the line does not already have it printed at the end.
• Draw a line from the end of the words to the end of the line.

Examples:

Figures	Words on the check
$45.00	Forty-Five and 00/100 Dollars
$1,250.50	One Thousand Two Hundred Fifty and 50/100 Dollars
$3,007.09	Three Thousand Seven and 09/100 Dollars
$12,480.75	Twelve Thousand Four Hundred Eighty and 75/100 Dollars
$0.99	Zero and 99/100 Dollars

For whole-dollar amounts, write “and 00/100” or “and no/100”. Leaving the cents blank invites someone to add them.

Why the words matter

Banks and the law treat the written amount as the main one. Under Article 3 of the Uniform Commercial Code, which every state has adopted, words prevail over numbers when the two disagree. A check with “$1,500.00” in the box and “One hundred fifty” on the line is legally a check for $150. In practice, many banks will return a check with mismatched amounts instead of guessing, and processing systems that read the figures automatically may flag it for manual review.

Getting the words right protects you as well. A neat, complete legal amount with a line drawn after it is much harder to alter than figures alone, which can be changed by adding a digit.

Rules for writing numbers in words

US check-writing convention follows a few simple rules, and the converter applies all of them:

• Hyphenate compound numbers from twenty-one to ninety-nine: forty-five, ninety-nine.
• Do not use “and” inside the dollar amount. Write “one hundred fifty”, not “one hundred and fifty”. The word “and” marks where the dollars stop and the cents begin.
• Leave out commas. They are fine in figures but not needed in words.
• Use thousand, million and billion. Above that you are unlikely to be writing a check.
• Write the cents as two digits over 100, including a leading zero: 05/100, not 5/100.

Capitalizing the first word is enough. The converter capitalizes each word, which is how many printed checks look, and it can also give you the whole line in capitals, which is what most check printing software uses. Banks accept all three.

The words-only format

Choose words only when the cents need to be spelled out too, or when the document is not a check. $1,250.50 becomes “One Thousand Two Hundred Fifty and Fifty Cents”, and a whole-dollar amount has no cents part at all. This is the wording used in many contracts, gift letters and receipts, where the fraction format would look out of place. Add “dollars” after the dollar amount if your document needs it, for example “One Thousand Two Hundred Fifty dollars and Fifty Cents”, and put the figures in brackets after the words.

Writing the date, payee and memo

The amount is only one part of a correct check. Write the date in full, for example “March 4, 2026”. Postdating a check does not stop a bank from paying it early unless you give the bank a formal notice. Write the payee’s full legal name, the name of a business as it appears on its invoice rather than a person who works there. Use the memo line for an invoice or account number so the payee can apply the payment to the right bill. Sign with the same signature the bank has on file. If you make a mistake anywhere, write VOID across the check and start again. Do not try to correct it.

Where else you need an amount in words

Checks are the most common use, but the same wording appears in other documents:

• Promissory notes and loan agreements, where the principal is stated in words and figures.
• Contracts and leases that state rent, deposits or purchase prices.
• Invoices and receipts, where some businesses add the total in words.
• Money orders and cashier’s checks, which you fill in by hand at the counter.
• Gift letters for a mortgage, which state the gift amount.

Legal documents often put the figures in brackets after the words: “Fifteen thousand dollars ($15,000.00).” Use the words-only format and add the figures yourself.

Common mistakes

• Writing “and” twice, as in “One hundred and fifty and 00/100”. Only the “and” before the cents belongs there.
• Forgetting the cents on a whole-dollar amount, which leaves room to add some.
• Spelling forty as “fourty”. Four, fourteen and fourth keep the u; forty does not.
• Writing “twelve hundred” for 1,200. It is understood, but “one thousand two hundred” is the safer form on a check.
• Leaving space before the words or after them without a line.

Business checks and printing software

Accounting software such as QuickBooks prints the legal amount automatically, usually in capitals and often padded with asterisks to fill the line. If you write checks by hand from a business account, or need to type the amount into a template, paste the converter’s capitals output and add asterisks or a line after it.

For payments to vendors, it is worth confirming the other numbers on the check too. The routing number validator checks the nine-digit number at the bottom left of a check, and the EIN validator checks the format of a vendor’s tax ID before you issue a Form 1099. If you are working out a figure that includes tax, the sales tax calculator gives the total first.

Mobile deposit and the amount line

When a check is deposited by phone, the bank’s software reads both the figures and the words from the photo. Clear handwriting on the legal amount line helps it match the two without sending the check to a person for review, which can delay the funds by a day or more. Keep the words on one line, write in dark ink, and avoid squeezing the cents into the margin.

Frequently asked questions

How do I write $1,500 on a check?

Write “One thousand five hundred and 00/100” on the amount line, followed by “Dollars” if it is not printed already, and draw a line to the end. “Fifteen hundred and 00/100” is also accepted by banks, but the thousands form is clearer and is what check printing software uses.

How do I write cents on a check?

Write the cents as a fraction over 100 after the word “and”. For $25.30, write “Twenty-five and 30/100”. For an amount under a dollar, such as $0.75, write “Zero and 75/100 Dollars”, and consider writing “Cents only” in the memo to make it clear.

What happens if the words and numbers on a check do not match?

Under the Uniform Commercial Code the words control. Many banks will still return the check or hold it for review rather than pay a disputed amount. If you notice a mismatch before the check is deposited, void it and write a new one rather than correcting it.

Should I write “and” in a check amount?

Only once, between the dollars and the cents. “One hundred fifty and 25/100” is correct. “One hundred and fifty and 25/100” uses “and” twice, which makes it unclear where the dollars end. The converter always places “and” in the right spot.

Do I need to capitalize the amount in words?

No. Banks accept lower case, sentence case or all capitals. Most people capitalize the first word. Printed business checks usually use all capitals because they are easier to read and harder to alter. Choose whichever you prefer and copy it from the converter.

Can I use the converter for amounts in millions?

Yes. It handles up to 15 digits, which reaches the trillions, so “Two Million Three Hundred Forty Thousand and 00/100 Dollars” is no problem. Large amounts are more common on promissory notes, closing documents and wire instructions than on personal checks, and the same wording rules apply.
