Questions
Frequently asked
The Public Provident Fund (PPF) is a government-backed, long-term savings scheme with a 15-year lock-in. The interest rate is notified by the government every quarter - currently 7.1% per annum - and interest is compounded annually. Both the rate and the sovereign guarantee make it one of the safest ways to build a tax-free corpus.
Each year your deposit is added to the balance and the whole balance earns the annual rate, compounded yearly. Depositing the ₹1.5 lakh annual maximum for 15 years at 7.1% grows to about ₹40.68 lakh - of which ₹22.5 lakh is your contribution and the rest is tax-free interest. This calculator runs that year-by-year compounding for your numbers.
The minimum is ₹500 and the maximum is ₹1,50,000 per financial year, across all your PPF accounts combined. Deposits qualify for a Section 80C deduction (old tax regime). To maximise returns, deposit before the 5th of the month, since interest is calculated on the lowest balance between the 5th and month-end.
Yes - PPF enjoys EEE (exempt-exempt-exempt) status: the deposit is deductible under Section 80C (old regime), the interest earned is tax-free, and the maturity amount is tax-free. This makes the effective return considerably higher than a taxable FD at the same rate.
Yes. After the initial 15-year term you can extend in blocks of 5 years, with or without further contributions, and the balance keeps earning interest. Use the tenure slider (15, 20, 25… years) to see how extending compounds your corpus further.
Partial withdrawals are allowed from the 7th year onward, subject to limits, and loans against the balance are available between years 3 and 6. Full withdrawal before maturity is permitted only in specific cases (such as serious illness or higher education) after 5 years. PPF is designed as a long-term, lock-in instrument.
