See how long Kisan Vikas Patra takes to double your money at the current 7.5% rate (as of Q1 FY 2026-27 (verify quarterly notification)), and the guaranteed 2× maturity amount.
How KVP doubles your money
Kisan Vikas Patra is built around one promise: at the rate fixed when you buy, your investment grows to exactly twice its value at maturity. The doubling period depends only on the rate, because compounding is annual:
Years to double = ln(2) ÷ ln(1 + r)
The government publishes the doubling period in months each quarter alongside the rate. Once you buy a certificate, that period is locked in for that certificate, regardless of later rate changes.
Worked example: ₹1,00,000 at 7.5%
At the current 7.5% rate, ₹1,00,000 grows to ₹2,00,000 in about 9 years 4 months (112 months). The interest earned equals your original investment — that is the whole point of KVP. Enter today's notified rate above to see the exact period, since the rate is reviewed every quarter.
Who KVP suits
KVP is sold at post offices and select banks to any resident individual — the "kisan" in the name is historical, not a restriction. It carries a sovereign guarantee, has a minimum of ₹1,000 (then multiples of ₹100) and no maximum. The lock-in is 2 years 6 months, after which premature encashment is allowed. It is ideal for someone who wants a guaranteed doubling within a known, fixed time frame.
The tax catch — and the alternatives
KVP gives no Section 80C deduction, and the interest is fully taxable at your slab rate. That makes its after-tax return weaker than the headline suggests. If you can lock money for 15 years, PPF — whose interest is entirely tax-free — usually wins. For flexible tenures, compare a bank FD, and for regular income in retirement see the SCSS calculator. Choose KVP specifically for the certainty of doubling, not for tax efficiency.
Frequently Asked Questions
What is Kisan Vikas Patra (KVP)?
KVP is a fixed-return savings certificate from India Post that doubles your money over a fixed period set by the current interest rate. Despite the name (kisan = farmer), it is open to all resident individuals. It carries a sovereign guarantee and is sold at post offices and select banks.
How long does KVP take to double money?
At the current 7.5% rate (as of Q1 FY 2026-27 (verify quarterly notification)), KVP doubles in about 9 years 4 months — 112 months. The exact period is fixed when you buy and stays unchanged for that certificate, even if the government revises rates later. The calculator shows the period for any rate you enter.
How is the KVP doubling period calculated?
KVP compounds annually (the government publishes the doubling months each quarter). Mathematically, the time to double is years = ln(2) ÷ ln(1 + r), then converted to months and rounded. At 7.5% that works out to 112 months. Enter today's notified rate above for the current period.
Is KVP interest taxable?
Yes. KVP offers no tax deduction on investment (it is not under Section 80C) and the interest is fully taxable at your slab rate. There is no TDS on the maturity payout, but you must declare the interest in your income tax return. Estimate the tax with our
income tax calculator.
Can I withdraw KVP before maturity?
KVP has a lock-in of 2 years and 6 months. After that you can encash it prematurely at the post office. Before the lock-in, premature closure is allowed only on the holder's death or by a court order. Held to maturity, you receive exactly double your investment.
KVP vs FD vs PPF — which should I choose?
KVP gives a guaranteed doubling with a clear time frame but no tax benefit. A
bank FD is more flexible on tenure.
PPF is the standout if you can lock money for 15 years — its interest is completely tax-free (EEE), which usually beats KVP's taxable return. Pick KVP mainly for the certainty of doubling within a known period.
What is the minimum and maximum investment in KVP?
The minimum is ₹1,000, and thereafter in multiples of ₹100. There is no maximum limit on the total you can invest. KVP can be bought singly, jointly, or by a guardian on behalf of a minor.
