Questions
Frequently asked
What is PPF and what return does it give?
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.
How is PPF maturity calculated?
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.
How much can I invest in PPF each year?
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.
Is PPF tax-free?
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.
Can I extend PPF beyond 15 years?
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.
Can I withdraw from PPF before 15 years?
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.
