KVP Calculator (Kisan Vikas Patra)
See how a Kisan Vikas Patra grows. Enter your investment and the interest rate — KVP doubles your money, and the calculator shows the maturity value and how long it takes.
Kisan Vikas Patra (KVP) is a government-backed savings certificate sold at post offices whose defining feature is simple: it doubles your money. You invest a lump sum, and after a fixed period set by the current interest rate, you receive exactly twice your investment. This calculator shows the maturity value and the doubling period for your chosen amount and rate.
How KVP maturity is calculated
Interest is compounded annually, and the government fixes the tenure so the maturity is always double the principal. The doubling period is derived from the rate.
Doubling period (months) = ln(2) ÷ ln(1 + rate ÷ 100) × 12
At the current 7.5% rate, KVP doubles in 115 months (9 years and 7 months).
| Investment at 7.5% | Maturity | Period |
|---|---|---|
| ₹50,000 | ₹1,00,000 | 115 months |
| ₹1,00,000 | ₹2,00,000 | 115 months |
| ₹5,00,000 | ₹10,00,000 | 115 months |
Worked example
Investing ₹1,00,000 in KVP at 7.5%:
| Maturity value (doubles) | ₹2,00,000 |
| Interest earned | ₹1,00,000 |
| Doubling period | 115 months (9y 7m) |
Is KVP right for you?
KVP suits conservative savers who want a guaranteed doubling with a sovereign guarantee and don't need the money for about a decade. There's no upper limit on investment and it can be transferred or used as loan collateral. Note the downsides: KVP does not offer a Section 80C tax deduction, and the interest is fully taxable, so post-tax returns are lower than tax-advantaged schemes like PPF or NSC. It's best seen as a safe, simple parking spot for a lump sum.
