How to use this KVP calculator
- Enter the amount you will invest. The minimum is ₹1,000, then multiples of ₹100, with no maximum.
- Check the interest rate. It starts at 7.5%, the rate for October–December 2026. For a certificate you already hold, enter the rate from when you bought it, and the calculator uses the months for that rate.
- Open "More options" and pick your tax slab to see what you keep after tax.
The result shows the maturity value, the time to double and the yearly return, with a table of the value for each year and what the certificate pays if you encash it then. The tax figures are estimates using your slab rate plus 4% cess.
How KVP doubles your money
Kisan Vikas Patra is a government savings certificate sold at post offices and authorised banks. It has one promise: your deposit doubles at maturity. The government doesn't choose the rate and the period separately. It sets the rate, then fixes the maturity period at about the time money takes to double at that rate, compounded yearly.
Months to double ≈ (ln 2 ÷ ln (1 + r)) × 12 r is the yearly rate as a decimal. At 7.5%: 0.6931 ÷ 0.0723 × 12 is about 115 months, which is the official maturity period of 9 years and 7 months. A quick check is the rule of 72: 72 ÷ 7.5 is about 9.6 years.
Worked example
You invest ₹1,00,000 at 7.5%. It matures after 115 months at ₹2,00,000, so you earn ₹1,00,000 of interest, all paid at maturity. On paper the certificate is worth about ₹1,07,501 after one year, ₹1,43,568 after five and ₹1,91,737 after nine.
Nothing is paid before maturity. If you encash after 5 years you get ₹1,37,000 from the official table, which is ₹6,568 less than the value on paper.
KVP maturity value by amount
At 7.5%, every amount doubles in 115 months:
| You invest | Maturity value | Interest earned |
|---|---|---|
| ₹10,000 | ₹20,000 | ₹10,000 |
| ₹50,000 | ₹1,00,000 | ₹50,000 |
| ₹1,00,000 | ₹2,00,000 | ₹1,00,000 |
| ₹5,00,000 | ₹10,00,000 | ₹5,00,000 |
| ₹10,00,000 | ₹20,00,000 | ₹10,00,000 |
KVP value by year
On ₹1,00,000 at 7.5%. The middle column is the value on paper; the last is what you actually receive if you encash at that point:
| Year | Value on paper | Interest so far | If you encash |
|---|---|---|---|
| 1 | ₹1,07,501 | ₹7,501 | Only in special cases |
| 2 | ₹1,15,564 | ₹15,564 | Only in special cases |
| 3 | ₹1,24,233 | ₹24,233 | ₹1,20,800 |
| 4 | ₹1,33,551 | ₹33,551 | ₹1,28,600 |
| 5 | ₹1,43,568 | ₹43,568 | ₹1,37,000 |
| 6 | ₹1,54,337 | ₹54,337 | ₹1,45,900 |
| 7 | ₹1,65,914 | ₹65,914 | ₹1,55,400 |
| 8 | ₹1,78,359 | ₹78,359 | ₹1,65,500 |
| 9 | ₹1,91,737 | ₹91,737 | ₹1,76,300 |
| Maturity (115 months) | ₹2,00,000 | ₹1,00,000 | ₹2,00,000 |
How the months have changed with the rate
Your rate and maturity period are fixed the day you buy, so an older certificate keeps its own period. These are the rates since 2018, from the National Savings Institute:
| Bought between | Rate | Money doubles in |
|---|---|---|
| Since 1 April 2023 | 7.5% | 115 months (9 yrs 7 mos) |
| January to March 2023 | 7.2% | 120 months (10 yrs) |
| October to December 2022 | 7.0% | 123 months (10 yrs 3 mos) |
| April 2020 to September 2022 | 6.9% | 124 months (10 yrs 4 mos) |
| July 2019 to March 2020 | 7.6% | 113 months (9 yrs 5 mos) |
| October 2018 to June 2019 | 7.7% | 112 months (9 yrs 4 mos) |
| January to September 2018 | 7.3% | 118 months (9 yrs 10 mos) |
The calculator uses these official months when you enter one of these rates. For any other rate it works out the months with the formula above, so treat that as an estimate.
Encashing a KVP early
A KVP has more flexibility than an NSC, because you can leave after two and a half years. You then receive a fixed amount from the scheme's table, whatever the reason:
| Held for | Paid on ₹1,000 | Paid on ₹1,00,000 |
|---|---|---|
| 2½ years to under 3 years | ₹1,171 | ₹1,17,100 |
| 3 to under 3½ years | ₹1,208 | ₹1,20,800 |
| 3½ to under 4 years | ₹1,247 | ₹1,24,700 |
| 4 to under 4½ years | ₹1,286 | ₹1,28,600 |
| 4½ to under 5 years | ₹1,328 | ₹1,32,800 |
| 5 to under 5½ years | ₹1,370 | ₹1,37,000 |
| 5½ to under 6 years | ₹1,414 | ₹1,41,400 |
| 6 to under 6½ years | ₹1,459 | ₹1,45,900 |
| 6½ to under 7 years | ₹1,506 | ₹1,50,600 |
| 7 to under 7½ years | ₹1,554 | ₹1,55,400 |
| 7½ to under 8 years | ₹1,604 | ₹1,60,400 |
| 8 to under 8½ years | ₹1,655 | ₹1,65,500 |
| 8½ to under 9 years | ₹1,708 | ₹1,70,800 |
| 9 to under 9½ years | ₹1,763 | ₹1,76,300 |
| 9½ years to before maturity | ₹1,819 | ₹1,81,900 |
Each band works out to about 6.5% a year compounded, one percentage point below the 7.5% you earn by holding to maturity. Because each amount applies for six months, encash just after a new band starts. The last step is the biggest: leaving even a month before maturity costs you ₹18,100 on ₹1,00,000. This table applies to certificates opened on or after 1 April 2023.
Before two and a half years, a KVP can be closed only on the death of a holder, on forfeiture by a pledgee who is a gazetted officer, or by court order. You then get your deposit plus simple interest at the Post Office Savings Account rate for the complete months held.
How KVP is taxed
KVP has no tax benefit. The list of investments that count towards the old regime's ₹1.5 lakh limit names NSC but not KVP, and the new regime has no such deduction at all. The Income-tax Act does not list KVP interest as tax-free either, so treat it as taxable at your slab rate.
| On ₹1,00,000 for 115 months | You keep | Yearly return |
|---|---|---|
| Before tax | ₹2,00,000 | 7.5% |
| 20% slab plus cess | about ₹1,79,200 | about 6.28% |
| 30% slab plus cess | about ₹1,68,800 | about 5.62% |
All the interest arrives at maturity, so ask your tax adviser whether to report it each year as it builds up or in the year you receive it, and use the same approach throughout. The calculator shows the total tax, not the timing.

- Where: at post offices and authorised banks, or through post office internet banking.
- Amount: at least ₹1,000, in multiples of ₹100, with no maximum and any number of certificates.
- Term: set by the rate on the day you buy, 9 years and 7 months at 7.5%.
- Transfer: it can move between post offices, and to another person in limited cases such as the death of the holder or a court order.
- Security: you can pledge it for a loan, to a bank for example.
- After maturity: money left in earns only the Post Office Savings Account rate, 4% at present.
KVP, NSC or an FD?
If you pay tax under the old regime and have room in your limit, an NSC pays more over a shorter term and gives you the deduction, but you cannot leave early by choice. A KVP suits money you want to set aside for a long time, with a way out after two and a half years. If you prefer income, see the Post Office Monthly Income Scheme. Compare a bank deposit with the FD calculator, or a tax-free PPF account. To compare any two returns on the same footing, use the CAGR calculator.
