Convert any dollar amount to words for writing checks, legal documents, and invoices.
Write the numeric amount in the box (e.g. $1,250.00)
On the amount line, write the words: "One thousand two hundred fifty and 00/100"
Draw a line after "100" to fill the remaining space and prevent alterations
Capitalize the first letter and sign in ink
Write the full dollar amount in words followed by "and 00/100" for whole dollar amounts, or "and XX/100" for amounts with cents. Example: $1,250 → "One thousand two hundred fifty and 00/100".
Yes — capitalize the first letter of the written amount. Banks expect "One thousand" not "one thousand". This also makes the amount harder to alter fraudulently.
"and 00/100" represents zero cents (zero out of one hundred cents). If the amount has cents, write "and 50/100" for 50 cents, etc.
Banks typically honor the written amount in words over the numeric amount in the box. Always make sure both match to avoid issues.
