What each PPF input means
- Yearly deposit
- What you put in each financial year: at least ₹500 and at most ₹1,50,000 across all your deposits, made in up to 12 instalments or at once.
- Interest rate
- The PPF rate, 7.1% since 1 January 2024. The government reviews it every quarter; the rate you enter is held constant.
- Tenure
- 15 for the standard term, or 20, 25 and so on if you extend in five-year blocks with deposits.
PPF formula
Balance_y = (Balance_{y−1} + Deposit) × (1 + r)
Each year's deposit is added to the balance and the whole sum earns the year's interest, compounded once a year. The government sets the PPF rate every quarter; it has been 7.1% since 1 January 2024. Interest is worked out each month on the lowest balance between the fifth day and the end of the month and credited at the end of the year, so a deposit made by 5 April earns interest for the whole year, which is what this calculator assumes. The account runs for 15 full financial years and can then be extended in blocks of five years, with or without further deposits.
PPF worked example
Depositing the maximum ₹1,50,000 every year for 15 years at 7.1% gives a maturity value of ₹40,68,209 against ₹22,50,000 deposited, ₹18,18,209 of it interest. Contributions, interest and the maturity payout are all tax-free under the old regime, the reason PPF is a long-term staple.
More PPF examples
₹50,000 a year for 15 years at 7.1% matures at ₹13,56,070: ₹7,50,000 deposited and ₹6,06,070 of interest.
Extending twice, for 25 years in all, and keeping up the ₹1,50,000 deposits takes the balance to ₹1,03,08,015, over a crore from ₹37,50,000 deposited: the last ten years add more interest than the first fifteen.
₹1,00,000 a year with one five-year extension, 20 years in all, reaches ₹44,38,859, of which ₹24,38,859 is interest: more than was ever deposited.
Where the PPF calculator can give the wrong answer
- Deposits above ₹1,50,000 in a year aren't allowed in a real account and earn no interest, even though the calculator accepts a larger number.
- Deposits made after the 5th of a month earn no interest for that month; spreading deposits through the year gives slightly less than this projection, which assumes a deposit by 5 April.
- The government revises the rate every quarter; the projection holds the rate you enter constant for the whole term.
- Partial withdrawals, allowed from the seventh year, and loans in years three to six aren't modelled.

PPF FAQ
- 7.1% a year, compounded yearly, the rate in force since 1 January 2024. The Ministry of Finance reviews small-savings rates every quarter, so check the current notification before relying on it.
- By the 5th of April. Interest is worked out each month on the lowest balance between the 5th and the month's end, so a deposit on or before the 5th earns interest for that month, and a single deposit by 5 April earns it for the whole year.
- Yes, in blocks of five years, with or without further deposits. Extending with deposits at the maximum is how ₹1,50,000 a year turns into more than a crore after 25 years at 7.1%.
- Partly. One withdrawal a year is allowed from the seventh financial year, and loans are available between the third and sixth years. Closing the account early is allowed only for specific reasons, such as serious illness or higher education.
- The account is treated as discontinued. It can be revived by paying the minimum ₹500 for each missed year plus a ₹50 penalty for each; until then it can't be used for loans or withdrawals.
- No. PPF is exempt at every stage: the interest each year and the maturity payout are tax-free, whichever regime you file under.
- No, it projects the balance only. Deposits qualify for the 80C deduction under the old regime; under the new regime they don't, but interest and maturity stay tax-free either way.
