Paise & Decimal Rules — Writing Fractions of a Rupee in Words
By WordsForNumbers Editorial Team · Updated 2026-09-30 · 43 min read
Write the fraction after "and": Rs 250.75 = "two hundred fifty rupees and seventy-five paise". One paisa (singular), two paise (plural) — "paisas" is always wrong. Never let a converter drop the decimal: 125000.50 must keep its fifty paise.
The core rules
- One rupee = 100 paise.
- Read the decimal as a two-digit number: .50 → "fifty paise", .05 → "five paise", .25 → "twenty-five paise".
- Singular only for exactly one: "one paisa". Everything else takes "paise".
- On cheques: "Rupees X and Y paise only".
- In ledgers and invoices, words and decimal figures must agree.
Examples
| Amount | In words |
|---|---|
| 10.01 | ten rupees and one paisa |
| 10.50 | ten rupees and fifty paise |
| 10.05 | ten rupees and five paise |
| 999.99 | nine hundred ninety-nine rupees and ninety-nine paise |
| 125000.50 | one lakh twenty-five thousand rupees and fifty paise |
Beware the decimal-dropping bug
Some online converters silently strip the decimal point — 125000.50 becomes 12,500,050 ("twelve million…"), which is off by a factor of 100. Always sanity-check converter output on money: if the paise vanished or the number grew digits, the tool is broken. Our converter parses decimals explicitly and this site's test suite covers the exact case.
Rounding vs exact paise
On cheques and invoices, write exact paise — never round. Rounding is only acceptable in casual speech ("about twenty-five thousand rupees"). Tax filings and bank documents require the precise figure.
Paise in Urdu and Hindi
Urdu: پچاس پیسے (pachaas paise) for fifty paise; one paisa is ایک پیسہ. Hindi: पचास पैसे (pachaas paise); one paisa is एक पैसा. The singular/plural logic is identical across all three languages: one paisa, two paise.
Tricky decimals, worked out
| Amount | In words | Watch out |
|---|---|---|
| 10.10 | ten rupees and ten paise | read .10 as “ten”, never “one-zero” |
| 10.01 | ten rupees and one paisa | singular “paisa” here |
| 0.99 | ninety-nine paise | no “rupees” at all |
| 5.00 | five rupees | drop the paise entirely |
| 100.99 | one hundred rupees and ninety-nine paise | — |
Paise on Pakistani and Indian documents
Both countries use paise as the subunit word — PKR and INR alike. On Pakistani cheques the standard form is “Rupees [words] and [words] paise only”, exactly mirroring Indian cheque conventions, so one rule covers both.
On money, the decimal is never optional: a dropped .50 once turned a one-lakh cheque into a ten-million dispute in a careless converter’s output.
Paise on invoices vs cheques
On invoices and bills, paise are usually written as figures (Rs 4,250.75) with the words carrying the full amount: "Rupees four thousand two hundred fifty and seventy-five paise only". On cheques, the same rule applies — never round paise off silently, because the words must match the figures box exactly or the bank may reject the cheque.
Paise on invoices and GST bills
Indian GST invoices must show paise exactly — a taxable value of Rs 1,240.55 with 18% GST gives Rs 223.30 tax and a Rs 1,463.85 total, and the words line must carry every paisa: “Rupees one thousand four hundred sixty-three and eighty-five paise only”. Pakistani sales-tax invoices follow the same two-decimal discipline. Never round an invoice total before writing it in words — the tax authority matches figures to words.
Salary slips: where paise quietly disappear
Most payslips round to whole rupees. Deductions like provident fund (12% of basic) are computed to paise and then rounded: 12% of Rs 45,000 = Rs 5,400.00 exactly, but 12% of Rs 45,333 = Rs 5,439.96, shown as Rs 5,440. The rounding rule is usually printed in the payroll policy — half a rupee and above rounds up.
Rounding rules that actually matter
- Standard rounding (half up): Rs 10.505 → Rs 10.51; Rs 10.504 → Rs 10.50.
- Indian income tax: total income is rounded to the nearest rupee (fractions of 50 paise or more round up) before tax is computed.
- Pakistani tax returns: amounts are likewise rounded to whole rupees on the filed return.
- Bank interest: always computed to paise — the bank never rounds in its own favour silently; the exact paise appear in your statement.
The 0.5 paise problem
The paisa is the smallest legal subunit — there is no “half paisa” in words. So what do you write for Rs 10.005? Round to two decimals first (Rs 10.01), then write “ten rupees and one paisa”. Three-decimal amounts appear on petrol and diesel price boards (Rs 96.487 per litre) and in forex rates (1 USD = 283.4567 PKR), but you only ever pay rounded to paise — the words on a receipt or cheque always use two decimals.
Bank FD interest: paise in action
Fixed-deposit interest is where paise are unavoidable. Rs 100,000 at 10% per annum compounded quarterly for one year matures at Rs 110,381.29 — those 29 paise must appear in the words: “Rupees one lakh ten thousand three hundred eighty-one and twenty-nine paise only”. Banks print the maturity amount in words on the FD advice exactly like this.
| Principal | Rate | 1-year interest | In words (interest) |
|---|---|---|---|
| 100,000 | 10% | 10,000.00 | ten thousand rupees |
| 250,000 | 9.5% | 23,750.00 | twenty-three thousand seven hundred fifty rupees |
| 100,000 | 10% quarterly | 10,381.29 | ten thousand three hundred eighty-one rupees and twenty-nine paise |
Receipts: exact paise or rounded?
Digital payments (UPI, bank transfer, cards) keep paise exact — Rs 499.99 stays Rs 499.99. Cash payments round to the nearest rupee because paisa coins barely circulate anymore. A shop receipt may print Rs 1,250.50 while you hand over Rs 1,251 in cash — the receipt's words, if any, must match the printed figure, not the cash handed over.

| 1.05 | one rupee and five paise | not “zero-five” |
| 100.01 | one hundred rupees and one paisa | singular paisa |
| 1,000.10 | one thousand rupees and ten paise | .10 = ten |
| 250.05 | two hundred fifty rupees and five paise | — |
| 10,000.99 | ten thousand rupees and ninety-nine paise | — |
Writing paise on legal documents
On stamp papers and sale deeds, the consideration is written with full paise words and no abbreviations: “Rupees seventy-five lakh fifty thousand four hundred twenty and seventy-five paise only (Rs 75,50,420.75)”. Drafting tip: write the words first, then the figures — it forces you to confront every paisa instead of copying digits blindly. See the Pakistan cheque guide for the parallel cheque convention.
Fuel boards quote three decimals, forex quotes four — but the words on money you actually pay always stop at paise.
