No lump sum? Save monthly instead
KVP needs a one-time lump sum. If you'd rather build the same maturity from monthly savings, a recurring deposit at about 6.7% over the same 9 yr 7 mo would need roughly:

You'd contribute ₹1.42 L in total across 115 deposits — more than the ₹1.00 L KVP lump sum, because monthly money has less time to compound. RD rate is illustrative.
How much should you invest
The KVP lump sum to invest today — and the equivalent monthly RD — to reach each maturity goal at 7.5% (9 yr 7 mo to double).
| Maturity goal | Invest in KVP (lump sum) | Interest earned | Or save monthly (RD) |
|---|---|---|---|
| ₹5.00 L | ₹2.50 L | ₹2.50 L | ₹3,095/mo |
| ₹10.00 L | ₹5.00 L | ₹5.00 L | ₹6,190/mo |
| ₹20.00 L | ₹10.00 L | ₹10.00 L | ₹12,379/mo |
| ₹50.00 L | ₹25.00 L | ₹25.00 L | ₹30,948/mo |
| ₹1.00 Cr | ₹50.00 L | ₹50.00 L | ₹61,896/mo |
KVP doubles, so the lump sum is half the goal; interest makes up the other half. Monthly RD figures assume 6.7% over 115 months (illustrative).

- Designed to double your money: maturity is fixed at exactly 2× your investment.
- Fixed return — the doubling period is locked in the day you buy, immune to later rate cuts.
- Safe and predictable, suited to long-term savers who can lock money away for ~9–10 years.

Key insight
KVP's appeal is the guaranteed doubling, not a high rate. Your ₹1.00 L becomes ₹2.00 L in 9 yr 7 mo — certain and safe. But the interest is taxable, and over the same horizon equity or PPF can build more wealth (with risk or a longer lock-in). Treat KVP as a safe doubling parking spot.

Compare KVP's guaranteed doubling with NSC, PPF, FD and other safe fixed-return options.
Only KVP's 2× doubling is fixed by the scheme. The FD, PPF, RD and savings-account figures shown are typical published rates used for context, not live quotes or guarantees. KVP interest is taxable and rates are reset by the government each quarter — confirm the current rate at your post office before buying.
How a KVP maturity is calculated
t = ln(2) ÷ ln(1 + r) and M = P × (1 + r)ᵗ
- M
- maturity (fixed by the scheme at 2× the principal)
- P
- lump sum invested
- r
- annual rate ÷ 100 (compounded yearly)
- t
- doubling tenure in years = ln(2) ÷ ln(1 + r)
Worked example
With your inputs — ₹1.00 L at 7.5%: the annual rate is r = 0.075, so the doubling tenure is t = ln(2) ÷ ln(1 + 0.075) ≈ 9.58 years (115 months, or 9 yr 7 mo). Compounding annually over that tenure, M = ₹1.00 L × (1 + 0.075)9.58 ≈ a maturity of about ₹2.00L — roughly 2× your investment, with ₹99,985 of it being interest. The 2× is fixed by the scheme; this is the engine's computed figure, before tax (KVP interest is taxable).
Most asked KVP questions
KVP is a fixed-income savings certificate from India Post that compounds your money at a government-set rate until it exactly doubles. You invest a lump sum and get back twice the amount at maturity — the holding period is fixed on the day you buy, so the doubling is guaranteed by the scheme.
The doubling time depends on the rate at purchase: time = ln(2) ÷ ln(1 + rate). At the current 7.5% it works out to about 115 months (9 years 7 months). A higher rate means a shorter wait, and the period is locked in when you invest. The Rule of 72 (72 ÷ rate) is a quick mental cross-check.
Yes — KVP is a government-backed scheme and the maturity value is fixed at exactly twice your investment, with the holding period locked in on the day you buy. Unlike market-linked investments there is no uncertainty about the amount you get back, only the wait. The rate (and so the doubling period) is reset each quarter, but once you've bought, your certificate's terms don't change.
Yes. The interest earned on KVP is fully taxable as 'income from other sources' and is added to your income each year. There is no TDS at source, but you must declare and pay tax on it yourself.
No. Unlike PPF or NSC, KVP investments do not qualify for a Section 80C deduction. You invest with post-tax money and the interest is taxable too, so KVP is about guaranteed doubling, not tax savings.
Yes. A KVP certificate can be transferred from one person to another or between post offices, and you can pledge it as collateral for a loan. There's a lock-in of 2 years 6 months before premature encashment is allowed (with the applicable lower return).
Only KVP's doubling is fixed by the scheme. The FD, PPF, RD and savings-account figures here are typical current or published rates shown for context only — actual returns on those vary and are not guaranteed. Treat every comparison as a rough reference, not advice.
The complete guide to Kisan Vikas Patra
Why KVP is all about doubling
Kisan Vikas Patra is a small-savings certificate issued by India Post that is built around a single promise: your money doubles. The government sets the interest rate each quarter, and the certificate compounds annually until the maturity value reaches exactly twice your investment. Because the doubling period is fixed at the moment you buy, a higher rate simply shortens the wait — the destination never changes, only the time it takes to get there.
How the doubling time is calculated
The maturity is fixed at 2× your principal, so the only variable is time. With annual compounding, the exact doubling period is ln(2) ÷ ln(1 + rate) — at the current 7.5% that's about 115 months, or 9 years 7 months. The popular Rule of 72 (72 ÷ rate) gives a fast mental estimate that lands close to the precise figure. This calculator shows both, plus the year your balance passes each step on the way to doubling.
Is the return guaranteed?
Yes — and that's the point. KVP is government-backed, the maturity value is fixed at twice your investment, and the holding period is locked in on the day you buy. Unlike equity, gold or even a fresh FD booked later, there's no uncertainty about the amount you get back. The only thing the quarterly rate reset changes is the doubling period for new certificates, not ones you already hold.
Taxation: no 80C, and interest is taxable
KVP is not a tax-saving instrument. There is no Section 80C deduction on what you invest, and the interest is fully taxable as "income from other sources", added to your income each year. There's no TDS at source, so you must declare and pay the tax yourself. If tax efficiency matters more than guaranteed doubling, PPF (tax-free) or NSC (80C-eligible) may suit you better.
Who can invest, and how much
Any resident adult can buy KVP — singly, jointly, or on behalf of a minor — at a post office or select public-sector bank. The minimum is ₹1,000 and there's no upper limit, though investments of ₹50,000 or more need a PAN and larger amounts need source-of-funds documents. Certificates are transferable between people and post offices, and can be pledged for a loan, with a 2½-year lock-in before premature encashment.
When KVP makes sense — and when it doesn't
KVP suits savers who want a certain, government-backed return and don't mind locking money away for the best part of a decade. It's simple, safe and transferable. But its real return after tax is modest, and for long-horizon goals — retirement, a child's education years away — equity and even gold have historically built more wealth, at the cost of volatility. Confirm the current rate at your post office before buying.
