About the KVP Calculator
This KVP calculator shows what a Kisan Vikas Patra investment is worth at maturity and exactly when it matures. KVP is a Government of India small savings certificate sold at post offices and authorised banks whose defining feature is simple: your money doubles. Enter the amount you invest and the date of investment, and the calculator returns the maturity value, the interest earned, the doubling period in months, the maturity date and the equivalent annual return, plus a year-by-year view of how the certificate’s value builds.
KVP suits conservative investors who want a sovereign-backed, fixed return and do not need the money for nearly ten years. The rate is fixed on the day you invest and applies until maturity. The National Savings Institute lists 7.5% compounded annually, with money doubling in 115 months, for deposits from 1 April 2023, and the Department of Economic Affairs kept small savings rates unchanged for October–December 2026. You can also pick an older notified rate to check a certificate you already hold, or enter a custom rate to see how a future rate change would alter the doubling period.
Rules to know: the minimum investment is ₹1,000, in multiples of ₹100, with no upper limit. Certificates can be encashed early only after 2½ years, at the lower values in the government’s premature encashment table. KVP interest is taxable as income from other sources and there is no Section 80C deduction.
With the default inputs, the maturity value is ₹200,000.00. Change any value above to recalculate instantly.

Formula and method
A Kisan Vikas Patra is designed to double your money, so the maturity amount is always twice the investment. What the interest rate determines is how long doubling takes: at an annual compounded rate r, money doubles after ln 2 ÷ ln(1 + r) years. At 7.5% that is 9.58 years, which the government notifies as 115 months. Notified periods are set by the government, so for listed rates the calculator uses the official figure; for a custom rate it rounds the formula to the nearest month.
The year-wise table shows the certificate’s value growing at the equivalent annual rate. It is indicative only — if you encash early (allowed after 2½ years) the post office pays the amount in the official premature encashment table, which is slightly lower.

Worked examples
₹1,00,000 invested on 1 October 2026 at 7.5%
At the current 7.5% rate KVP doubles in 115 months, so ₹1,00,000 becomes ₹2,00,000 on 1 May 2036 — 9 years and 7 months later. Doubling in 115 months is equivalent to about 7.5% a year compounded annually.
Older certificate at 6.9% (124 months)
A ₹50,000 KVP bought in June 2021 earned 6.9% and doubles in 124 months, paying ₹1,00,000 on 15 October 2031.
What if the rate rose to 8%?
At 8% compounded annually money doubles in ln 2 ÷ ln 1.08 = 9.006 years, about 108 months, so a ₹1,00,000 certificate would mature on 1 October 2035.
