Questions
Frequently asked
KVP is a government-backed savings certificate sold at post offices that doubles your investment over a fixed period. You invest a lump sum; at the notified rate (currently around 7.5%, compounded annually) it grows to exactly twice your money. The capital is fully guaranteed.
The doubling period is set by the rate. At 7.5% compounded annually, money doubles in about 115 months (9 years 7 months). The government announces both the rate and the corresponding maturity period each quarter; if the rate rises, the doubling period shortens.
It follows the rule of compound growth: months to double = ln(2) ÷ ln(1 + rate) × 12. At 7.5% that works out to ~115 months. This calculator shows the exact period for whatever rate you enter, alongside the doubled maturity amount.
Yes. KVP does not offer a Section 80C deduction, and the interest is taxable at your slab rate. There’s no TDS on KVP, but the gain should be declared. It’s best suited to those who simply want a safe, guaranteed doubling of capital rather than tax savings.
KVP has a lock-in of 2 years 6 months, after which premature encashment is allowed at set intervals with the applicable interest. Before that, withdrawal is permitted only in special cases such as the holder’s death or a court order. It’s designed to be held to maturity.
