KVP Calculator

Kisan Vikas Patra, or KVP, is the post office scheme with the simplest promise of all: whatever you put in comes back doubled. There are no monthly payouts, no deposits to keep up and no market risk. The only question is how long the doubling takes, and that depends on the interest rate on the day you buy. The calculator above answers it, and if you enter the purchase date, it gives the date your certificate matures. This guide explains how the period is set and what else to know before you buy.

How to use the calculator

1. Set the amount you will invest, from ₹1,000 upwards, in multiples of ₹100. There is no upper limit.
2. Check the rate. It starts at the current KVP rate. For a certificate bought earlier, set the rate that applied then.
3. Enter the purchase date if you want the maturity date.

The results show the maturity amount, which is always twice the deposit, the number of months it takes, the interest earned and the equivalent yearly return. The table shows roughly what the certificate is worth at the end of each year as it grows.

How long KVP takes to double

The government announces the KVP rate every quarter together with the maturity period, the number of months in which the deposit doubles. At the current rate of 7.5%, the period is 115 months, or 9 years 7 months.

The two numbers are linked by compounding. Money growing at 7.5% a year, compounded once a year, doubles after:

Years to double = log 2 ÷ log(1 + rate ÷ 100)

At 7.5% that is 0.6931 ÷ 0.0723 = 9.58 years, or 115 months. Historically the period has been 120 months at 7.2%, 123 months at 7.0% and 124 months at 6.9%; the calculator uses the notified 115 months at the current rate, and for any other rate you try it works out the doubling time to the nearest month, which can differ by a month from what the government notified at that rate.

A certificate keeps the period that applied on the day it was bought. If the rate changes next quarter, certificates already bought are not affected.

What different amounts become

The interest is always equal to the deposit. That makes KVP easy to plan with: the deposit you need is half the amount you want in 9 years 7 months.

Finding the maturity date

Add the maturity period to the date of purchase. A certificate bought on 10 November 2026, with 115 months to run, matures on 10 June 2036. Enter your date in the calculator and it does the counting.

The amount is payable on that date. It does not earn more if you leave it uncollected for a long time, so encash it once it is due.

The value as it grows

KVP pays nothing before maturity, but the certificate's value grows every year. For ₹1,00,000 at 7.5%, it is worth roughly:

These are the values implied by doubling in exactly 115 months. If you encash early, the post office pays from its own table of encashment values, which follows the same shape but differs slightly; use it for the exact figure.

Encashing early

A KVP can be encashed after 2 years and 6 months from the date of purchase. You get the value from the encashment table, which includes interest earned so far but is well below the maturity amount.

Before 2 years and 6 months it can be closed only:

• on the death of the holder, or of any holder in a joint certificate;
• on forfeiture by a pledgee who is a gazetted government officer; or
• on an order of a court.

So KVP suits money you can leave alone for close to ten years. It can be pledged as security for a loan, which helps if you need funds without breaking it.

How KVP is taxed

• No Section 80C deduction. Unlike NSC or PPF, the amount you invest gives no tax benefit, in either regime.
• The interest is taxable at your slab rate. You can show it year by year as it accrues, or all in the year of maturity. Year by year spreads the tax; all at maturity adds nearly ten years' interest to a single year's income, which can push you into a higher slab.
• No TDS is deducted by the post office, so the responsibility for reporting the interest is yours.

At a 30% slab plus cess, the post-tax return is well below 7.5%. For a retired person with income below the taxable limit, KVP's full return is kept.

Who can buy a KVP

• Any resident Indian adult, alone or in a joint certificate of up to three adults.
• A guardian on behalf of a minor or a person of unsound mind, and a minor of 10 or older in their own name.
• Despite the name, it is not limited to farmers.
• NRIs and HUFs cannot buy KVP. Trusts cannot either.

Because there is no upper limit, there are anti-money-laundering checks: PAN is required above ₹50,000, and proof of the source of funds, such as a salary slip, bank statement or tax return, above ₹10 lakh.

KVP against an FD and NSC

KVP's return is fixed and government-backed, and it beats most bank FDs over a similar period. Its main drawbacks are the long term and no tax benefit. Compare your bank's rate with the FD calculator, and look at the NSC calculator if you also want the 80C deduction. For regular monthly income instead of a lump sum later, the Post Office MIS calculator shows what the same deposit pays each month.

Planning with KVP

Because the result is always exactly double, KVP works well for a goal with a known date roughly ten years away. Decide the amount you will need, halve it, and invest that today. For ₹10 lakh needed in about ten years, ₹5 lakh in KVP now gets there in 9 years 7 months, with five months to spare.

Two things to keep in mind:

• Inflation. ₹10 lakh in 2036 will buy much less than ₹10 lakh today. At 5% inflation, prices rise by about 60% over 9 years 7 months, so the doubling is a real gain of only about a quarter.
• Tax. If your slab is high, the post-tax amount is less than double. Plan with the post-tax figure, or keep KVP for a family member with a lower income.

Opening a KVP

Buy it at any post office counter with a filled application form (Form A), your identity and address proof, PAN where needed, and the money by cash, cheque or transfer. You receive a certificate or a passbook entry; keep it safe, since it is needed at maturity. Name a nominee when you buy, so the money reaches your family without a court process if anything happens to you. A lost certificate can be replaced by applying at the post office with an indemnity bond.

What this calculator assumes

• The deposit doubles in the maturity period notified for the current rate, 115 months at 7.5%. For any other rate, the period is the doubling time with yearly compounding, to the nearest month.
• The maturity amount is exactly twice the deposit, rounded to a multiple of ₹100 with a minimum of ₹1,000.
• The equivalent yearly return is the compounded rate that doubles money in that many months.
• The values year by year are approximate; actual early-encashment values come from the post office's table.
• The maturity date adds the maturity period in whole months to the purchase date.
