PPF: ₹1.5 Lakh a Year for 15 Years
Depositing ₹1.5 lakh a year in a PPF account for 15 years gives a maturity value of about ₹40.68 lakh at 7.1%. You deposit ₹22.5 lakh and the rest, ₹18.18 lakh, is interest.
PPF rates are set by the government and reviewed every quarter, so 7.1% is the rate that has applied in recent quarters, not a guarantee for the next 15 years. Check the current rate and enter it in the calculator.

Interest outgrows your deposits
Interest in year 15 alone is ₹2.7 lakh, about 1.8 times that year's ₹1.5 lakh deposit. Over the full 15 years the interest adds up to 81% of what you put in.
Why the 5th of the month matters
PPF interest is worked out each month on the lowest balance between the 5th and the month end, and credited at the end of the financial year. A deposit made by the 5th of April earns interest for all 12 months of that year. If you deposit later in the year, or in smaller monthly amounts, the first year's interest will be lower than this calculation assumes, so the real maturity value will be a little under it.
After 15 years
PPF can be extended in blocks of 5 years. Leave the ₹40.68 lakh in the account without adding more and it still earns interest, reaching about ₹57.33 lakh after 5 more years. Keep depositing ₹1.5 lakh a year and it reaches about ₹66.58 lakh. The extension rules differ for the "with deposits" and "without deposits" options, so check them with your bank or post office when you reach year 15.
Rules that affect your plan
These are the rules as we last checked them. Confirm the current ones with the scheme notification before you rely on a date or a limit.
- The yearly deposit limit is ₹1.5 lakh and the minimum is ₹500, across the whole financial year.
- The account has a 15-year lock-in. Partial withdrawals are allowed from the seventh financial year, up to a limited share of the balance.
- A loan against the balance has been available between the third and sixth years.
- Interest and the maturity amount are tax-free. The deduction for deposits applies only under the old tax regime.

Does the PPF interest rate change?
Yes. The government announces the rate every quarter. It has stayed near 7.1% for some time, but the calculator lets you test a lower or higher rate.
Can I withdraw before 15 years?
Partial withdrawal is allowed from the seventh financial year, up to a limit. Full premature closure is allowed only in specific situations and after 5 years. Check the current terms.
