When a cheque, invoice or contract asks for an amount in words, you write the number out in full — 10070 becomes "ten thousand seventy". Banks, courts and tax offices treat the written words as the real amount when the figures and the words disagree, so getting it right protects you. If you want the answer in seconds, use our free number to words converter — type the number and it writes the words for you. The rest of this guide covers the rules, the two number systems used in South Asia and the West, and the mistakes that cause cheques to bounce.
Why amounts are written in words
Figures are easy to change. A 1 can become a 7 with one stroke of a pen, and a 0 can be added at the end of a number without much effort. Words are harder to alter without leaving a mark. That is the whole reason banks ask for the amount in words on a cheque. If someone changes the figures, the words still show what the cheque was really for, and the bank follows the words.
The same habit shows up in invoices, loan agreements and contracts. A loan agreement states the borrowed amount in figures and in words so both sides agree on one number. Courts treat the written words as the amount that counts when the two do not match. If you ever sign a rent agreement or a loan paper, read the words version of the amount before you sign. For loan paperwork, the figures also decide what you pay each month — our EMI calculator shows the monthly cost of a loan, and the amount in words on the agreement should match the loan amount you entered there.
The rules: hyphens, "and" and capital letters
Three rules cover most of the writing. First, use a hyphen for numbers from twenty-one to ninety-nine when they stand alone or sit inside a larger number. Twenty-one, forty-five and ninety-nine all take a hyphen. One hundred does not. Second, use "and" only before the tens and ones after a hundred or a thousand in British style. One hundred and twenty-one is the usual form in Pakistan and the UK. American writing often drops the "and" and writes one hundred twenty-one. Banks in Pakistan accept both, but pick one style and keep it through the whole document. Third, capital letters are not needed. Amounts in words are written in lower case, except at the start of a sentence or when a cheque form prints "Rupees" with a capital R. "Rupees ten thousand seventy only" reads fine on a cheque. One more point: after the full amount, write "only" at the end. It stops anyone from adding extra words after your amount.
Western numbers vs lakh and crore
In Pakistan, India and Bangladesh, people count in lakhs and crores. In the UK and the US, the same numbers are counted in millions and billions. The value is the same; only the grouping changes. A lakh is 100,000. A crore is 10,000,000. One million is 1,000,000, which is ten lakh. One billion is 1,000,000,000, which is one hundred crore. Confusion starts when a document mixes the two systems. An invoice that says "Rs 10 lakh" is clear to a reader in Lahore and confusing to a reader in London. A contract that says "one million rupees" is clear in London and needs a second look in Lahore. If your document will be read in both places, write the figure in digits next to the words and state the system once, for example "Rs 1,000,000 (one million rupees / ten lakh rupees)".
| Number | Western system | South Asian system |
|---|---|---|
| 1,000 | one thousand | one thousand |
| 100,000 | one hundred thousand | one lakh |
| 1,000,000 | one million | ten lakh |
| 10,000,000 | ten million | one crore |
| 100,000,000 | one hundred million | ten crore |
Smaller numbers read the same in both systems. 10070 is "ten thousand seventy" whether you count in millions or in lakhs, because lakh and crore only start at 100,000. The two systems only part ways above that line.
Decimals and currency: rupees and paisas
A cheque amount with decimals is written in two parts. The rupees come first, then the paisas after "and". Rs 1,250.75 becomes "rupees one thousand two hundred and fifty and paisa seventy-five only". Some banks write "paisa" in the singular and some write "paise" — both forms are accepted. When there are no paisas, write the full amount and add "only". "Rupees five thousand only" leaves no room for a later change.
Invoices follow the same pattern, with one difference. An invoice usually shows the tax and the discount as separate lines, and each line gets its own amount in words only if the form asks for it. Most invoices only need the grand total in words. If you need to work out a discount or a tax amount before you write it, a percentage calculator gives you the figure in seconds, and you can write that figure in words on the invoice.
Common mistakes
The most common mistake is putting the "and" in the wrong place. "One thousand and seventy" is wrong for 1070 — the correct form is "one thousand seventy". The "and" belongs after a hundred, not after a thousand. The second mistake is the hyphen. "Twenty one" without a hyphen looks wrong on a formal document, and "twenty-one" is the accepted form. The third mistake is mixing systems. Writing "one lakh seventy thousand" or "one hundred seventy thousand" for the same number is fine. The error is writing "1.7 lakh" in figures and "one million seven hundred thousand" in words — those are different amounts.
A fourth mistake is leaving a gap after the amount. Always close the line with "only" and draw a line through any blank space left on a cheque. An open gap invites someone to add words. The fifth mistake is spelling. "Forty" has no "u". "Ninety" has no "e" after the "t". Cheques with spelling errors are often sent back by the bank.
Convert any number to words in seconds
Rules are useful, but typing a number and getting the words back is faster — and it removes the spelling mistakes. Open the number to words converter, type the amount, and copy the words onto your cheque, invoice or contract. It handles large numbers, decimals and both the Western and South Asian systems. If you work with loans, EMIs or percentages often, the rest of the calculators in the Converters & Calculators category cover those jobs the same way — free, in your browser, with nothing to install.
Frequently asked questions
Do banks accept numbers written without "and"? Yes. Banks in Pakistan accept both "one hundred twenty-one" and "one hundred and twenty-one". The amount is what matters, not the "and".
What does 10070 look like in words on a cheque? Ten thousand seventy. Write "Rupees ten thousand seventy only" and draw a line through the space that is left.
Is "lakh" accepted on legal documents? Yes, in Pakistan, India and Bangladesh. If the document will be read abroad, add the Western form in brackets so both sides read the same amount.
