What is PPF (Public Provident Fund)?
Public Provident Fund (PPF) is an Indian government-backed long-term savings scheme. Deposits up to INR 1.5 lakh per year qualify for Section 80C deduction. The interest (currently 7.1% for Q4 FY 2024/25) and maturity proceeds are completely tax-free, giving PPF the rare EEE (exempt-exempt-exempt) tax status with a 15-year lock-in.
Detailed definition
PPF was launched by the Government of India in 1968 to encourage long-term savings and provide retirement security to non-salaried citizens. It is administered through post offices and authorised banks. Anyone (resident individual) can open one account; a parent or guardian can open one on behalf of a minor.
PPF has the most generous tax status in the Indian system. Deposits qualify for Section 80C deduction (up to INR 1.5 lakh per year). The interest, which compounds annually and is announced quarterly by the Ministry of Finance, is completely tax-free. Maturity proceeds and partial withdrawals are also tax-free, making PPF a true triple-tax-exempt (EEE) instrument.
The trade-off is illiquidity. PPF has a 15-year lock-in from the date of opening. Partial withdrawals are permitted after the end of the 7th financial year, subject to limits. Premature closure is only allowed in cases of life-threatening illness, higher education, or change of residency status. After 15 years, the account can be extended in 5-year blocks, with or without further contributions.
The timing of deposits within each month directly affects returns. PPF interest is calculated monthly on the minimum balance held in the account between the 5th and the last day of the month. If you deposit on the 6th, you forfeit interest for that entire month. Disciplined subscribers either set a standing instruction to credit on the 1st of every month, or make a single lump-sum deposit on or before 5 April (the start of the financial year) to capture interest on the full INR 1.5 lakh for all 12 months. Over a 15-year horizon this timing discipline can add INR 60,000 to INR 70,000 to the final corpus relative to year-end depositors.
PPF also offers a low-cost loan facility that few subscribers exploit. From the start of the 3rd financial year through the end of the 6th, you can borrow up to 25% of the balance at the end of the 2nd preceding year. The rate is 1% above the PPF rate (currently 8.1%) and the loan must be repaid within 36 months. This is far cheaper than personal-loan rates (typically 11% to 18%) and the borrowing does not interrupt the EEE tax status. Note that once a loan is outstanding, you cannot borrow again until it is fully repaid - so plan the request size carefully.
Formula
Future Value at Maturity = P x [((1 + r)^n - 1) / r] x (1 + r)
- P = Annual contribution (up to INR 1,50,000)
- r = Current PPF interest rate (decimal, e.g., 0.071 for 7.1%)
- n = Number of years (15 for original term)
Worked example
Suppose you contribute INR 1.5 lakh per year to PPF for the full 15-year term, and the interest rate averages 7.1% per annum.
- Annual contribution: INR 1,50,000
- Years: 15
- Average interest rate: 7.1% per annum
- Total contributed: INR 1.5 lakh x 15 = INR 22.5 lakh
- Maturity corpus (approx.): INR 40.7 lakh

Frequently asked questions
What is the current PPF interest rate?
PPF interest is 7.1% per annum for Q4 FY 2024/25, unchanged since April 2020. The Ministry of Finance reviews and announces the rate every quarter based on government securities yields.
What is the PPF deposit limit?
Minimum deposit is INR 500 per financial year, maximum INR 1,50,000. The cap applies across all PPF accounts held by the same individual (including minor accounts opened in their name).
How is PPF interest calculated?
Interest is calculated on the minimum balance between the 5th and last day of each month. Deposits made before the 5th of a month earn interest for that month - so contributing early in the month is more efficient.
Can I withdraw money from PPF before 15 years?
Partial withdrawals are allowed from the end of the 7th financial year, up to 50% of the balance at the end of the 4th preceding year. Premature closure is only allowed for serious illness, higher education, or NRI status change.
What is the difference between PPF and EPF?
PPF is a voluntary scheme open to any resident individual; EPF is a mandatory employer-employee scheme for salaried workers in covered organisations. EPF rates (currently 8.25%) are higher and EPF has an employer match, while PPF has lower contribution limits.
Is PPF interest fully tax-free?
Yes. PPF enjoys EEE status - deposits, interest, and maturity are all exempt from income tax. This is one of the few remaining EEE instruments in India after the 2021 changes to high-EPF interest taxability.
Can I take a loan against my PPF balance?
Yes. From the start of the 3rd financial year until the end of the 6th, you can borrow up to 25% of the balance at the end of the 2nd preceding year. The interest rate is 1% above the PPF rate (currently 8.1%), and the loan must be repaid within 36 months. No further loan is allowed until the first one is fully repaid.
