How is PPF maturity calculated?

PPF interest is compounded annually, so the maturity is built up year by year: each year your deposit is added to the running balance, then annual interest at the notified rate is applied to that balance, and the result carries into the next year. After 15 such rounds you have the maturity value. This calculator models exactly that year-by-year roll-up for the yearly deposit, rate, and term you enter, and separates the total you deposited from the tax-free interest earned. Depositing ₹1.5 lakh a year at 7.1% for 15 years, for example, matures to about ₹40.68 lakh.

What is the current PPF interest rate?

The PPF rate is 7.1% per year as of 2025. The government reviews and notifies small-savings rates, including PPF, every quarter, so the rate can change over the long life of an account. Interest is calculated annually on the balance. Because the rate is not fixed for the whole term, this calculator keeps it as an adjustable input — use the prevailing rate for a current projection, and re-run with a different figure to see how a future change would affect your maturity.

How much can I deposit in PPF each year?

You must deposit at least ₹500 and at most ₹1,50,000 in a financial year to keep a PPF account active and compliant. The ₹1.5 lakh ceiling also aligns with the Section 80C deduction limit, which is why many savers deposit exactly that amount to maximise both tax-free growth and the tax deduction. Deposits can be made in a lump sum or in instalments through the year, up to a maximum number set by the scheme. This calculator assumes a consistent yearly deposit; vary the amount to see the effect of depositing less than the cap.

Can I withdraw from PPF before 15 years?

PPF has a 15-year lock-in, but limited access is allowed. Partial withdrawals are permitted from the seventh financial year onward, subject to limits based on the balance. Loans against the balance are available between the third and sixth years. Premature closure of the entire account is allowed only in specific situations — such as serious illness or higher education — and usually with an interest penalty. For planning purposes this calculator assumes deposits run for the full term without withdrawal, which gives the maximum maturity value.

Are the figures I enter stored anywhere?

No. The entire calculation runs in JavaScript inside your own browser. Nothing you enter — yearly deposit, rate, or term — is uploaded, logged, or stored on any server. The tool is free, needs no login, and closing the tab clears everything. There is no account and no saved history.

A PPF calculator works out what a Public Provident Fund account grows to over its term, given a yearly deposit and the government-notified interest rate. Enter the annual deposit, the rate (7.1% as of 2025), and the number of years, and it shows the maturity value, the total you will have deposited, and the tax-free interest earned. Because PPF compounds annually and is entirely tax-free, it is one of the most reliable long-term savings instruments in India. Everything runs in your browser, so nothing you type is sent anywhere.

What this is and why it matters

The Public Provident Fund is a government-backed long-term savings scheme that has anchored Indian household saving for decades. You open an account with a bank or post office, deposit between ₹500 and ₹1.5 lakh each financial year, and the balance compounds annually at a rate the government sets every quarter — 7.1% as of 2025. The account runs for a statutory 15 years and can then be extended in five-year blocks. What sets PPF apart is its EEE tax status: the deposits are deductible under Section 80C, the interest accrues tax-free, and the entire maturity amount is paid out tax-free, a combination almost no other instrument offers.

A PPF calculator matters because the maturity figure is built up year by year and is genuinely hard to estimate by hand. Each year’s deposit is added to a balance that has already earned interest, and the next year’s interest is calculated on the larger total — fifteen rounds of annual compounding. Depositing the full ₹1.5 lakh every year for 15 years at 7.1% matures to about ₹40.68 lakh, of which only ₹22.5 lakh is your own contribution; the remaining ₹18 lakh-plus is tax-free interest. Seeing that split is what makes PPF’s slow, steady compounding tangible, and why it remains a cornerstone of retirement and long-term goal planning even when its rate looks modest next to equities.

Because the notified rate changes over time, the calculator keeps the rate as an adjustable input rather than hard-coding it. You can model the current 7.1%, test what a higher or lower future rate would do to your maturity, and compare partial deposits against the full ₹1.5 lakh cap. For anyone weighing how much of their Section 80C limit to route through PPF, seeing the long-term maturity for different yearly amounts turns the decision into a concrete number.

How to use this tool

Enter the yearly deposit. Type the amount you plan to deposit each financial year, between ₹500 and the ₹1.5 lakh annual cap. The breakdown updates as you type, with nothing submitted anywhere. Many savers deposit the full ₹1.5 lakh to maximise both the tax-free growth and the Section 80C deduction, but any consistent amount works.

Set the interest rate. The rate defaults to 7.1%, the notified PPF rate as of 2025. Because the government revises it every quarter, you can adjust it to model a different rate — for instance to see how a future cut or rise would affect your maturity. For a current projection, leave it at the prevailing rate.

Choose the term. PPF has a statutory minimum of 15 years, which is the default. If you intend to extend the account in five-year blocks after maturity, set a longer term (such as 20 or 25 years) to see how much the extension adds — the later years benefit from the largest compounding base and add disproportionately to the final corpus.

Read the breakdown. The panel shows the maturity value at the end of the term, the total amount you will have deposited, and the tax-free interest earned. Adjust any input to plan: raise the yearly deposit toward the cap, extend the term, or test a different rate, and watch how the maturity and the deposit-versus-interest split respond.

Examples and use cases

Maximising the annual limit

A salaried saver in Mumbai deposits the full ₹1,50,000 every year into PPF at 7.1% for the full 15-year term. Entering ₹1,50,000, 7.1%, and 15 years shows a maturity of about ₹40.68 lakh, against total deposits of ₹22.5 lakh — more than ₹18 lakh of tax-free interest. Because the entire amount is tax-free on withdrawal, this is the headline figure that makes PPF a retirement cornerstone.

A smaller, steady contribution

A freelancer in Indore deposits ₹50,000 a year at 7.1% for 15 years. The calculator shows a maturity of about ₹13.56 lakh against ₹7.5 lakh deposited — roughly ₹6 lakh in tax-free interest. It demonstrates that even a modest but consistent yearly deposit, well under the cap, builds a meaningful tax-free corpus over the full term.

The effect of extending beyond 15 years

A saver who has maxed out ₹1.5 lakh a year extends the account by one five-year block, to 20 years total, at 7.1%. The maturity rises from about ₹40.68 lakh at 15 years to roughly ₹66 lakh at 20 years — the extra five years add far more than the first five, because they compound on the largest balance. Modelling the extension shows why many savers keep PPF running well past the minimum.

Planning around a rate change

A cautious planner wants to see what happens if the PPF rate falls from 7.1% to 6.5% for a full-cap deposit over 15 years. Re-running at 6.5% gives a maturity of about ₹38.9 lakh versus ₹40.68 lakh at 7.1% — a difference of nearly ₹1.8 lakh. Keeping the rate adjustable lets savers stress-test their long-term plan against the quarterly revisions the government makes.

Frequently asked questions

How is PPF maturity calculated?: PPF interest is compounded annually, so the maturity is built up year by year: each year your deposit is added to the running balance, then annual interest at the notified rate is applied to that balance, and the result carries into the next year. After 15 such rounds you have the maturity value.

Deposits can be made in a lump sum or in instalments through the year, up to a maximum number set by the scheme. This calculator assumes a consistent yearly deposit; vary the amount to see the effect of depositing less than the cap.
Is PPF really completely tax-free?: Yes. PPF carries EEE (exempt-exempt-exempt) status, which means it is tax-free at all three stages: the deposits qualify for deduction under Section 80C (up to ₹1.5 lakh a year), the interest that accrues each year is exempt from tax, and the entire maturity amount is paid out tax-free. Very few Indian instruments offer this complete exemption, which is why PPF’s effective post-tax return is higher than its headline rate suggests when compared with a taxable instrument like a fixed deposit at the same rate.
Can I withdraw from PPF before 15 years?: PPF has a 15-year lock-in, but limited access is allowed. Partial withdrawals are permitted from the seventh financial year onward, subject to limits based on the balance. Loans against the balance are available between the third and sixth years.
