PPF's 15-year lock-in and government-backed returns make it one of the safest long-term investments.

What is PPF?

The Public Provident Fund (PPF) is a government-backed long-term savings scheme with a mandatory 15-year lock-in. It offers a fixed interest rate set by the government every quarter, and both the interest earned and the maturity amount are entirely tax-free. Anyone, including a parent on behalf of a minor child, can open a PPF account at a bank or post office.

Worked Example — ₹1,50,000/year at 7.1%

15 years (minimum term)₹40,68,209.22Invested ₹22,50,000.00 · Interest ₹18,18,209.22
25 years (two 5-year extensions)₹1,03,08,014.97Invested ₹37,50,000.00 · Interest ₹65,58,014.97

Frequently Asked Questions

Depositing the maximum ₹1,50,000.00/year doesn't reach ₹1 crore within the base 15-year term — it takes about 25 years (the 15-year minimum plus two 5-year extensions) at a 7.1% rate to cross it, as shown in the worked example above.

Common Mistakes to Avoid

  • Deposits are modeled annually, not monthly. If you contribute monthly, enter your total for the year — PPF interest is credited annually regardless of how often you deposit.
  • The maximum is ₹1,50,000 per year, per person — not per account. Depositing more than the limit doesn't earn extra interest; the excess isn't eligible for interest or the Section 80C deduction.
  • 15 years is a minimum, not a fixed end date. PPF can only be extended in 5-year blocks after the initial 15 — a 17 or 22-year tenure isn't a valid closed term.
