KVP Calculator
Calculate Kisan Vikas Patra maturity amount, the money-doubling period and your exact maturity date.
What is Kisan Vikas Patra (KVP)?
Kisan Vikas Patra is a small savings certificate scheme run by the Government of India and sold through post offices and most public-sector banks. Its headline promise is simple: it doubles your money. You invest a lump sum today and, at the current interest rate of 7.5% per year compounded annually, your investment grows to exactly twice its value at maturity — currently in 115 months (9 years and 7 months).
Because KVP is backed by the central government, the returns are fully guaranteed and carry no market risk. The interest rate is reviewed quarterly by the Ministry of Finance, and the doubling period moves up or down whenever the rate changes. You can buy KVP for any amount of ₹1,000 or more (in multiples of ₹100), with no upper limit on investment.
How the KVP doubling period is calculated
The maturity amount is always double the investment, so the maturity value does not depend on the rate — only the time taken to double does. A higher interest rate doubles your money faster (a shorter period), while a lower rate stretches the period out. The calculator above rounds the doubling period up to the next whole month, exactly as India Post does on the certificate.

Frequently asked questions
How does a Kisan Vikas Patra calculator work?
A KVP calculator takes your investment amount and the current annual interest rate and works out how long your money will take to double. KVP always matures at exactly twice the amount invested, so the maturity amount is simply 2 × investment. The doubling period is found from the formula months = 12 × ln(2) / ln(1 + r), using annual compounding. At the current 7.5% rate, that is about 115 months — 9 years and 7 months.
How long does KVP take to double my money?
At the current notified rate of 7.5% per annum (compounded annually), Kisan Vikas Patra doubles your investment in 115 months, which is 9 years and 7 months. If the government changes the rate, the doubling period changes too — a higher rate doubles your money faster, a lower rate takes longer. The period applicable when you buy stays fixed for that certificate.
What is the minimum and maximum KVP investment?
The minimum investment is ₹1,000, and amounts above that must be in multiples of ₹100. There is no maximum limit on how much you can invest in Kisan Vikas Patra. However, for investments of ₹10 lakh and above, you must submit PAN and income proof.
Is there a lock-in period for KVP?
Yes. KVP has a lock-in of 2 years and 6 months (30 months) from the date of purchase. After this period you can encash the certificate prematurely. Before the lock-in ends, encashment is only allowed on the death of the holder, by a court order, or on forfeiture by a pledgee who is a gazetted officer.
Is KVP interest taxable and is it covered by Section 80C?
The interest earned on KVP is fully taxable and added to your income under the head "Income from Other Sources" at your slab rate. There is no TDS on KVP. Importantly, KVP does not qualify for any deduction under Section 80C, so it offers no tax saving on the amount invested.
Is the money safe in KVP?
Yes. Kisan Vikas Patra is a Government of India small savings scheme, so both the principal and the guaranteed doubling are backed by the sovereign. There is no market risk and the returns are assured, which makes KVP suitable for conservative investors with a long horizon.
