A PPF calculator projects the maturity value of a Public Provident Fund account — India's flagship long-term, government-backed savings scheme — from your yearly investment, the interest rate, and the tenure. Working as a combined PPF maturity calculator and PPF interest calculator, it's built for anyone planning retirement savings, a child's education fund, or any other long-horizon goal who wants to see how a fixed yearly contribution compounds over the mandatory 15-year lock-in, or over an extended tenure beyond 15 years in 5-year blocks.
You enter your planned yearly investment (up to the ₹1,50,000 annual cap), the interest rate (defaulting to the current government-notified rate of 7.1% p.a.), and the tenure in years. The calculator applies the annuity-due compounding formula — M = P × [((1+r)ⁿ − 1) ÷ r] × (1+r) — which assumes each year's deposit is made at the start of the financial year, the convention that maximizes interest and matches how PPF interest is actually credited by banks and post offices.
Salaried employees looking to supplement their EPF savings, self-employed individuals and freelancers who have no employer-sponsored retirement scheme, parents building a long-term fund for a child's education or marriage, and anyone wanting a zero-risk, tax-free component in a broader retirement plan alongside vehicles like NPS or a gratuity payout.
PPF is one of the few investment vehicles in India with full EEE (Exempt-Exempt-Exempt) tax status — the contribution qualifies for a Section 80C deduction, the interest is tax-free, and the maturity amount is tax-free too. Because the account locks funds in for 15 years (or longer with an extension), seeing the year-by-year growth and total maturity value upfront helps you decide how much of your annual investment budget to allocate to PPF versus other options like FDs, EPF, or market-linked SIPs. Modeling this before you commit avoids the frustration of realizing years into a 15-year lock-in that you allocated too much or too little.
This calculator assumes you invest at the start of each financial year, which maximizes interest — the standard PPF calculation convention
From yearly investment to maturity value in under a minute
Input the amount you plan to deposit each financial year — anywhere from ₹500 up to the ₹1,50,000 annual cap, which also doubles as your maximum Section 80C deduction for PPF.
The field defaults to 7.1% p.a., the current government-notified rate. Leave it as-is for a best-estimate projection, or lower it slightly to stress-test a long tenure against a possible future rate cut.
Select the standard 15-year lock-in, or an extended tenure of 20, 25, 30, 35, or 40 years to model continuing the account through one or more 5-year extension blocks.
The calculator applies the annuity-due formula instantly and displays your maturity value, total investment, and interest earned.

A full ₹1,50,000-a-year PPF projection over the standard 15-year term
Suppose you deposit the maximum ₹1,50,000 every financial year, before April 5th, into a PPF account earning the current 7.1% p.a., for the full 15-year lock-in.
| Year | Opening Balance | Deposit | Interest | Closing Balance |
|---|---|---|---|---|
| 1 | ₹0 | ₹1,50,000 | ₹10,650 | ₹1,60,650 |
| 2 | ₹1,60,650 | ₹1,50,000 | ₹22,046 | ₹3,32,696 |
| 15 | ₹36,72,650 (approx.) | ₹1,50,000 | ₹2,45,556 (approx.) | ₹40,68,206 |
Explanation: Notice how the interest credited each year keeps growing — from about ₹10,650 in year 1 to well over ₹2 lakh in year 15 — because interest compounds on an ever-larger balance. Roughly 45% of the final maturity value in this example comes from interest alone, illustrating why starting a PPF account early and staying consistent for the full tenure matters more than trying to time contributions later in life.
Extension example: if the same account is extended for one more 5-year block (20 years total) with continued ₹1,50,000 deposits at 7.1%, the maturity value grows to roughly ₹66,58,000 — illustrating how each additional 5-year block adds disproportionately more than the previous one, purely from compounding on a larger base.
How the interest rate you model changes your 15-year growth multiple
A useful way to sanity-check a PPF projection is the growth multiple — maturity value divided by total investment, for the standard 15-year term. This isn't an official benchmark, but it's a quick way to see whether the rate you've entered is producing a realistic outcome.
| Modeled Interest Rate | 15-Year Growth Multiple | Read |
|---|---|---|
| Below 6% | ~1.4x – 1.6x invested | Below the recent historical PPF band — still tax-free and guaranteed, but a smaller multiple |
| 7% – 8% (current: 7.1%) | ~1.7x – 1.9x invested | Matches the current and recent historical PPF rate range |
| 9% and above | ~2.1x invested or more | Above the current rate — useful for stress-testing an optimistic future scenario |
For long-term planners: since PPF's rate is revised quarterly and has generally stayed in the 7–8% band in recent years, using the default 7.1% is a reasonable base case. Model a lower rate for a conservative projection, especially for tenures beyond 20 years, since a lot can change over that horizon.
For extension decisions: compare the growth multiple at your planned tenure against a shorter one — each additional 5-year block compounds on an already-large balance, so extensions tend to add disproportionately more value than the same block would have added earlier.
Risk considerations: PPF carries no market or credit risk since it's a sovereign-backed scheme, but it does carry reinvestment/rate risk — the government can revise the rate every quarter, and a lower future rate reduces your actual maturity value versus this projection.
