How to write 15,000,000,000 in words

The number 15,000,000,000 is written “fifteen billion” in British English.

Because 15,000,000,000 is below one thousand it is a single group: name the hundreds and stop. That gives “fifteen billion”.

In running text the number is normally lowercase: “the fee is fifteen billion pounds”. At the start of a sentence, in a heading, or on a legal document it takes capitals: Fifteen Billion. Formal documents often give both forms together, for example “fifteen billion (15,000,000,000)”, so that a reader can check one against the other.

To turn “fifteen billion” back into digits, work group by group. Each group word (billion, million, thousand) marks a block of three digits. The result is 15,000,000,000, or 15000000000 without separators.

Commas go after every third digit counting from the right: 15,000,000,000. In Britain and the United States this is the standard grouping; in much of Europe the same number appears as 15.000.000.000, and international scientific style uses spaces: 15 000 000 000.

How to write 15,000,000,000 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.

15,000,000,000 in British and American English

15,000,000,000 is spelled exactly the same way – “fifteen billion” – in British and American English. The two varieties only differ when a number contains hundreds followed by tens or units, where British English adds “and”. Read more in our guide to British vs American English numbers.

15,000,000,000 in lakh and crore (India, Bangladesh and Pakistan)

In India, Pakistan, Bangladesh and Nepal, large numbers are grouped differently. After the first thousand the digits are grouped in twos, and the units are lakh (100,000) and crore (10,000,000). So 15,000,000,000 becomes 15,00,00,00,000, read as “one thousand five hundred crore” – or simply 1,500 crore.

Common mistakes when writing 15,000,000,000

  • Pluralising the group words. It is billion, never “hundreds”, “thousands” or “millions” after a number.
  • Using shorthand in formal documents. 15bn is fine in a message, but a cheque or contract needs fifteen billion or 15,000,000,000.
  • Miscounting the zeros. 15,000,000,000 has 11 digits. Check the commas: every group between commas should have exactly three digits.
