How your money grows to 2x
Value at month m = amount x 2^(m/115). The certificate pays everything at maturity; these are notional accrued values. Premature encashment (allowed after 2 years 6 months) pays scale-based amounts notified in the scheme rules.
₹1,00,000 over the same 115 months
| Scheme | Value after 115 months | Caveat |
|---|---|---|
| KVP (7.5%) | ₹2,00,000 | Guaranteed exact doubling, locked at purchase |
| Post Office 5-yr TD (7.5%) | ₹2,03,826 | If the 5-year TD rate held for 115 months (needs reinvestment after year 5) |
| NSC (7.7%) | ₹2,03,579 | If the NSC rate held for 115 months (NSC matures in 5 years, assumes reinvestment) |
KVP locks its doubling promise on the day you buy; the TD and NSC figures are projections that depend on future quarterly rate notifications. Figures rounded to the nearest rupee.
How Kisan Vikas Patra works and who it suits
KVP is the simplest promise in the Post Office stable: invest any amount and the Government of India returns exactly double on a fixed date. There is no rate to track, no compounding table to read and no payout schedule to manage. The certificate sold today matures in 115 months, and that doubling is locked on the day of purchase even if rates change in a later quarter.
It suits savers who want a guaranteed long-term outcome with sovereign backing and no investment ceiling: the minimum is ₹1,000 (multiples of ₹100) and there is no maximum, unlike PPF or SSY. The trade-offs are a long horizon, interest that is taxable at maturity, and no Section 80C deduction. Despite the name, no farming connection is needed; any resident adult can buy at a post office or authorised bank.
The doubling maths in plain language
A doubling period and an interest rate are two ways of saying the same thing. If money must double in 115 months with annual compounding, the implied rate is:
rate = 2^(12/115) - 1 = 0.0750 = 7.50% per year
That is why KVP is quoted at 7.5%: at 7.5% compounded annually, money doubles in about 115 months. When the ministry revises the KVP rate, it actually changes the doubling period (it was 124 months when the rate was 6.9%), and the calculator's timeline simply plots 2^(m/115) for each month m until it reaches 2x.
Worked example: ₹1,00,000 bought in June 2026
Buy a ₹1,00,000 certificate in June 2026 and it matures in January 2036 at exactly ₹2,00,000: ₹1,00,000 of principal back plus ₹1,00,000 of interest, all paid in one lump sum at maturity. Nothing is paid out along the way, which also means nothing is taxed along the way under the cash basis most savers use.
KVP rules at a glance

| Premature encashment | Allowed after 2 years 6 months at scale-based values |
| Pledging | Allowed; the certificate can be pledged as loan security |
| Transfer | Transferable between persons and between post offices |
| TDS | None deducted, but interest is taxable at maturity |
| Section 80C | Not available (NSC and the 5-year TD do qualify) |
KVP vs NSC vs 5-year TD: when each wins
On paper, both alternatives slightly outgrow KVP over the same 115 months if today's rates held: NSC at 7.7% compounded annually would turn ₹1,00,000 into about ₹2,03,579, and the 5-year TD at 7.5% with quarterly compounding into about ₹2,03,826, against KVP's exact ₹2,00,000. But both NSC and the TD mature in 5 years, so reaching 115 months means reinvesting at whatever rate prevails then; only KVP fixes the entire journey upfront.
- KVP wins when you want one locked, guaranteed outcome over 9.5+ years, or when you have already used up the ₹1.5 lakh 80C limit.
- NSC wins when you want the 80C deduction and a slightly higher rate over a 5-year horizon.
- 5-year TD wins when you may want yearly interest payouts or a shorter, more flexible commitment; try our Post Office FD calculator to run the numbers.

Frequently Asked Questions
How long does Kisan Vikas Patra take to double in 2026?
Exactly 115 months, which is 9 years and 7 months, at the current 7.5% rate. The doubling period is locked on the day you buy the certificate, so later rate revisions do not change your maturity. Rates effective Q1 FY 2026-27 (April - June 2026), unchanged since January 2024.
Is KVP tax free?
No. KVP has no Section 80C deduction on the investment, and the interest is fully taxable as income from other sources when the certificate matures. There is no TDS deducted by the post office, but you must declare the interest yourself. For a tax-saving alternative with a similar rate, NSC offers the 80C deduction.
Can I withdraw KVP before maturity?
Yes, after a lock-in of 2 years and 6 months from the date of purchase. Premature encashment pays a scale-based value notified in the scheme rules, which is lower than the full doubling. Encashment before 2.5 years is allowed only on the death of the holder, forfeiture by a pledgee or a court order.
KVP vs FD: which is better?
It depends on the horizon. The Post Office 5-year TD pays 7.5% with quarterly compounding and an 80C benefit, and if its rate held for 115 months it would grow ₹1,00,000 to about ₹2,03,826, marginally more than KVP's ₹2,00,000. But the TD locks its rate for only 5 years; KVP locks the full doubling for the entire 115 months on day one. Choose KVP for a long guaranteed outcome, the TD for a shorter commitment with a tax break.
Who can buy Kisan Vikas Patra? Do I need to be a farmer?
No farmer requirement at all, despite the name. Any resident Indian adult can buy KVP, singly or jointly (up to three adults), and a guardian can buy on behalf of a minor or a person of unsound mind. Minors above 10 can hold a certificate in their own name. NRIs and HUFs cannot invest.
Is there a maximum limit on KVP investment?
No upper limit. The minimum is ₹1,000 and amounts must be in multiples of ₹100, but you can invest any amount above that across any number of certificates. PAN is mandatory for investments above ₹50,000 and income proof above ₹10 lakh.
