Five Hundred and Fifty in Numbers

How to write 550 in words

The number 550 is written “five hundred and fifty” in British English. Notice the word “and”: British English places it between the hundreds and the rest of the group. American English usually leaves it out.

Because 550 is below one thousand it is a single group: name the hundreds, add "and", then name the remaining tens and units. That gives “five hundred and fifty”.

In running text the number is normally lowercase: “the fee is five hundred and fifty pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Five Hundred and Fifty. Formal documents often give both forms together, for example “five hundred and fifty (550)”, so that a reader can check one against the other.

How to write 550 on a cheque

Banks read the amount in words as the legal amount, so it must be exact. Write the pounds in words, add the word pounds, and finish with only so that nothing can be added afterwards.

• With pence: add the pence after the pounds – “Five hundred and fifty pounds and fifty pence only” for £550.50 – or write the pence as a fraction, “Five hundred and fifty pounds 50/100”.
• US check: “Five hundred fifty and 00/100 dollars”. American cheques drop the “and” after the hundreds and put it before the cents.
• Bangladesh, India and Pakistan: the currency word comes first and the amount is counted in lakh and crore – “Taka five hundred and fifty only”, with the figure written Tk. 550/=.

550 in British and American English

This is one of the numbers where the two spellings differ. British English keeps “and” after the hundreds; American English generally drops it.

Both are correct in their own country and both are understood everywhere. For a UK cheque, contract or exam, use the British form. See British vs American English numbers for the full comparison.

550 in Bangla (বাংলায় ৫৫০)

In Bangla, 550 is written ৫৫০ using Bengali digits, and in words it is পাঁচশো পঞ্চাশ. Bangla has its own word for every number from one to ninety-nine, and above that it counts in হাজার (thousand), লাখ (lakh) and কোটি (crore), the same grouping used across Bangladesh and India.

On a cheque or invoice written in Bangla the amount reads পাঁচশো পঞ্চাশ টাকা মাত্র (“পাঁচশো পঞ্চাশ taka only”). In English on the same cheque it is Taka five hundred and fifty only – see How to write a cheque in Bangladesh.

Common mistakes when writing 550

• Dropping “and”. five hundred fifty is American usage. In British English write five hundred and fifty.
• Pluralising the group words. It is hundred, never “hundreds”, “thousands” or “millions” after a number.
• Mixing words and figures. In running text keep to one style: five hundred and fifty or 550, not 550 (five hundred and fifty) unless it is a legal document.
