PPF is one of India's safest ways to build long-term wealth. You can invest between ₹500 and ₹1.5 lakh a year, and the government sets the interest rate each quarter (around 7.1% recently), compounded annually.
Its biggest draw is the tax treatment. Contributions qualify for a Section 80C deduction, the interest is tax-free, and the maturity amount is tax-free too — a rare triple exemption known as EEE.
The catch is liquidity: the account matures in 15 years, though partial withdrawals are allowed from year seven. For example, investing ₹1.5 lakh a year for 15 years at 7.1% builds a corpus of roughly ₹40 lakh, entirely tax-free.
