The Indian Number System — Lakhs and Crores
India uses a unique number system that differs from the international (Western) system in how large numbers are grouped and named. After one thousand, the Indian system groups numbers in pairs rather than threes.
| Number | Indian Format | Indian Words | International Words |
|---|---|---|---|
| 1,000 | 1,000 | One Thousand | One Thousand |
| 10,000 | 10,000 | Ten Thousand | Ten Thousand |
| 100,000 | 1,00,000 | One Lakh | One Hundred Thousand |
| 1,000,000 | 10,00,000 | Ten Lakh | One Million |
| 10,000,000 | 1,00,00,000 | One Crore | Ten Million |
| 1,000,000,000 | 1,00,00,00,000 | One Arab | One Billion |
💡All Indian legal documents, cheques, bank drafts, property deeds, and official financial papers must use Indian number terminology — lakhs and crores. Using "million" or "billion" on Indian official documents can cause confusion and may be rejected.
How to Write Rupees in Words on a Cheque
Writing cheque amounts correctly is essential — errors can lead to payment disputes, rejection by banks, or fraud opportunities. RBI guidelines specify that the amount in words is authoritative if there is a mismatch with the numeric figures.
- Start from the highest denomination: Crores → Lakhs → Thousands → Hundreds → Rupees → Paise
- Use "and" only before paise: "Five Thousand Rupees and Fifty Paise Only" — not "Five Thousand and Fifty Rupees"
- Always end with "Only": This prevents fraudulent additions to the amount
- No corrections allowed: If you make an error, cancel the cheque and rewrite on a new leaf
- Cross remaining blank space: Draw a horizontal line after the words to prevent additions
⚠️If the amount in words and figures differ on a cheque, the bank pays the amount written in words. Always verify both match before signing. A cheque with overwriting or corrections may be returned by the bank as "mutilated".
Number Words in Legal and Official Documents
Beyond cheques, writing numbers in words is required in many official Indian documents — property agreements, court filings, affidavits, demand drafts, fixed deposit receipts, and government applications. The conventions are slightly different from cheque writing:
- Property sale deeds: Both figures and words are mandatory. Example: "Rupees Fifty Lakh (₹50,00,000/-) Only"
- Court documents: Amounts written as "a sum of Rupees [amount in words] (₹[amount in figures])"
- Tender documents: Bid amounts must be in both words and figures — words prevail if different
- Bank instruments (DD, Pay Order): Same as cheques — words are authoritative
Frequently Asked Questions
Write the full amount starting from the highest denomination. For ₹1,25,500.75: "One Lakh Twenty-Five Thousand Five Hundred Rupees and Seventy-Five Paise Only". Always end with "Only" to prevent tampering. Use the Indian number system — lakhs and crores, not millions.
After hundreds, the Indian system groups in pairs: 1,00,000 = one lakh (not hundred thousand), 1,00,00,000 = one crore (not ten million). The sequence is: ones, tens, hundreds, thousands, ten-thousands, lakhs, ten-lakhs, crores, ten-crores, arab. Indian official and financial documents must use this system.
"Only" prevents fraudulent additions. Without it, "Five Thousand Rupees" could have "and Nine Hundred" appended. With "Only": "Five Thousand Rupees Only" is unambiguous. It's a mandatory security practice recommended by RBI for all bank instruments.
1 lakh = "One Lakh". In numbers: 1,00,000. In international format: One Hundred Thousand. For all Indian financial and legal documents, write "One Lakh" — not "One Hundred Thousand".
1 crore = "One Crore". In numbers: 1,00,00,000. In international format: Ten Million. For Indian official documents, always write "One Crore" — never "Ten Million".
Yes. RBI guidelines require amounts in both figures and words on cheques. If the two differ, banks honour the amount in words. Cheques without the amount written in words may be returned unpaid. Always complete both fields and verify they match before signing.
10 lakh = 10,00,000 = One Million in international format. Quick conversions: 1 lakh = 100 thousand, 10 lakh = 1 million, 1 crore = 10 million, 10 crore = 100 million, 100 crore = 1 billion.
