How to Write a Check Amount in Words: Complete Guide (with Examples)

Writing a check sounds simple — until you're staring at the written-amount line wondering whether to write "One thousand five hundred" or "One Thousand Five Hundred and 00/100 Dollars." Get it wrong and your bank may reject the check or hold it for verification.

This guide shows you exactly how to do it, with real examples and a free browser-based converter at the end.

The Anatomy of a Check's Written Amount Line

A US check has two amount fields:

The written line is the legally controlling one. If $1,500 is in the box but the written line says "One hundred fifty," most banks will pay $150. Always double-check they match.

Step-by-Step: How to Write the Amount

1. Write the dollar amount in words

Start with the whole dollar number, capitalized:

• $25 → Twenty-Five
• $100 → One Hundred
• $1,500 → One Thousand Five Hundred
• $12,750 → Twelve Thousand Seven Hundred Fifty

2. Write the cents as a fraction over 100

Even if there are no cents, you must include the fraction:

• No cents → and 00/100
• 50 cents → and 50/100
• 99 cents → and 99/100

3. End with "Dollars" (or "DOLLARS" in uppercase)

Most banks accept both styles. Some check designs print "DOLLARS" at the end already — in that case, stop before the word.

4. Draw a line to fill the rest of the space

After the amount, draw a straight line to the end of the field to prevent tampering:

One Thousand Five Hundred and 00/100 ——————————— DOLLARS

Examples: Common Check Amounts Written Out

Uppercase vs. Sentence Case: Which Is Correct?

Both are legally valid. Banks accept either. The difference:

• Uppercase (formal): ONE THOUSAND FIVE HUNDRED AND 00/100 DOLLARS
  Commonly used on printed checks, payroll systems, and official documents.

• Sentence case (standard): One Thousand Five Hundred and 00/100 Dollars
  More readable and widely used for handwritten checks.

Tip: Whatever style you choose, be consistent across the entire check.

Common Mistakes to Avoid

1. Writing "Forty" vs "Fourty"

There is no "u" in forty. It's always forty, not fourty. This is the most frequent spelling error in check writing.

2. Forgetting "and" before the cents

Correct: Two Hundred **and** 50/100 Dollars
Incorrect: Two Hundred 50/100 Dollars

The word "and" is the separator between dollars and cents in check writing. It's technically optional but strongly conventional.

3. Using "dollars" with a number vs "Dollars" at the end

Don't write "Two hundred dollars and 50/100." The currency word goes at the very end: Two Hundred and 50/100 Dollars.

4. Leaving blank space unfilled

Always draw a line after the amount to prevent someone from adding words like "teen" or "hundred" after what you wrote.

5. Mismatching the numeric and written amounts

Always verify they match. If they differ, your bank will likely honor the written amount — which could be more or less than you intended.

How Banks Handle Mismatched Amounts

Under the UCC (Uniform Commercial Code) which governs US checks:

If there is a conflict between words and figures, words control. But if the words are ambiguous, figures control.

In practice: most banks flag discrepancies and contact you. Some smaller amounts may clear automatically at the written value. Don't rely on "close enough" — write it right the first time.

Cents-Only and Round-Dollar Checks

Round dollar amounts (no cents):
One Thousand and 00/100 Dollars — always include the /100 fraction.
Some people write One Thousand and no/100 or One Thousand even — these are also accepted.

Cents-only (less than $1.00):
and 75/100 Dollars — start with "and" since there are no whole dollars.

FAQ

Can I write "one-thousand" with a hyphen?

Hyphens are used for compound numbers 21–99 (e.g., "twenty-one," "forty-five") but not around "hundred" or "thousand." Correct: "One Thousand Four Hundred Twenty-Three." Incorrect: "One-Thousand Four-Hundred Twenty-Three."

Is it okay to write checks in all lowercase?

It's technically valid but unusual. Banks might question it. Stick with title case or uppercase for clarity.

What if I make a mistake writing the amount?

Void the check and write a new one. Do not use correction fluid (white-out) on checks — banks won't accept corrected amounts and may flag it as fraudulent.

Do I write "Dollars" or "USD"?

Always write Dollars (or DOLLARS). "USD" is not standard for US checks.

My check already has "DOLLARS" printed at the end — do I still write it?

No. Just write the amount words up to the printed "DOLLARS": One Thousand Five Hundred and 00/100

What's the correct format for $0.50?

Fifty Cents or and 50/100 Dollars (starting with "and"). Both work; the second is more common on formal checks.
