PPF Calculator
Estimate your Public Provident Fund maturity value across a 15-year term, year by year.
The government reviews the PPF rate every quarter, so a 15-year projection at today's rate is an estimate, not a guarantee. See our Disclaimer.

The formula
PPF interest is compounded annually. This calculator assumes the full annual contribution is made at the start of each year, then adds interest on the resulting balance at year-end, repeated for the full tenure — a standard simplification used by most PPF calculators.
Worked example
₹1,50,000 invested every year for 15 years at 7.1% p.a.: maturity ≈ ₹40.68 lakh, against ₹22.5 lakh invested — interest earned ≈ ₹18.18 lakh.
Current PPF interest rate
As of the July–September 2026 quarter, the PPF rate is 7.1% p.a., set by the Ministry of Finance and reviewed every quarter (it has in fact stayed at 7.1% since April 2020). Since the rate can change in future quarters, a 15-year projection at today's rate is an estimate — check the current rate at the official source before relying on this for planning.
Method and sources
The deposit limits (₹500 to ₹1,50,000 a year) and the 15-year term follow the Public Provident Fund Scheme, 2019. The interest rate is notified each quarter by the Department of Economic Affairs, Ministry of Finance; the 7.1% shown here was announced on 30 June 2026 for July–September 2026. The maturity value is computed year by year as described above, and the worked example was recalculated independently when this page was last reviewed.
Limitations
Real PPF interest is calculated monthly on the lowest balance between the 5th and the end of each month, not once a year on a lump-sum deposit — depositing after the 5th of a month costs you that month's interest on that amount. This calculator uses the simplified start-of-year assumption above, which is accurate for a single deposit made on or before April 5th each year, and approximate otherwise. It also doesn't model partial withdrawals, loans against the account, or extensions beyond 15 years in 5-year blocks.
Frequently asked questions
Why is the maturity higher than what I get from just adding up the interest each year?
Because PPF compounds annually — each year's interest becomes part of the balance that itself earns interest the following year, so growth accelerates over the 15-year term rather than staying linear.
Can I withdraw money before 15 years?
Partial withdrawals are allowed from the 7th year onward, and loans against the balance from the 3rd year, both within limits set by PPF rules. This calculator only estimates the maturity value assuming no withdrawals.
What happens after 15 years?
You can withdraw the full maturity value, or extend the account in blocks of 5 years, with or without making further contributions. This calculator only estimates the value at the end of the initial term you enter.
