Kisan Vikas Patra (KVP) is a post office savings scheme with one simple promise: it doubles your money in a fixed period. Despite the name, anyone can invest, not just farmers. It is backed by the Government of India, so the return is guaranteed.
Key KVP rules
- Doubling period: 115 months (9 years 7 months) at the July–September 2026 rate of 7.5%, compounded yearly.
- Investment: minimum ₹1,000, in multiples of ₹100. There is no upper limit.
- Lock-in: you can encash it early only after 2 years and 6 months, at a lower value.
- Tax: there is no tax deduction on the investment, and the interest is taxable.
How to use the KVP calculator
- Enter the investment amount.
- Check the interest rate (the doubling period is worked out from it).
- Pick the date of investment to see the exact maturity date.
How the doubling period is calculated
Doubling period (months) = ln 2 ÷ ln(1 + rate ÷ 100) × 12At 7.5%, this gives 115 months. The rate on the day you invest decides your doubling period, and it stays fixed.
Example
You invest ₹1,00,000 in KVP on 1 October 2026 at 7.5%.
- Money doubles in 9 years 7 months
- Maturity date: 1 May 2036
- Maturity amount = ₹2,00,000
- Interest earned = ₹1,00,000
