KVP Calculator (Kisan Vikas Patra)
By Santaji GadepatilinUpdated October 27, 2026
Kisan Vikas Patra is a government savings certificate that doubles your money over a fixed period. The doubling time depends on the current interest rate. This free KVP calculator solves for whichever value you leave blank and shows the formula and steps.
How to use the KVP calculator
Enter the amount you will invest and the interest rate (7.5% for October–December 2026). The calculator shows how many months it takes to double and the maturity value.
How KVP works
Kisan Vikas Patra is a government-backed savings certificate sold at post offices. The amount invested doubles after a fixed period, which the government sets from the interest rate:
Months = ln 2 ÷ ln(1 + r) × 12
At 7.5% compounded yearly, that is 115 months.
