How PPF interest works
PPF interest is calculated monthly on the lowest balance between the 5th and the last day of the month, and credited once a year on 31 March. In practice that means compounding yearly, as long as you deposit before the 5th. You can deposit ₹500 to ₹1.5 lakh a year, in one go or in parts.
Tax benefits (EEE)
Under the old tax regime, deposits qualify for the ₹1.5 lakh Section 80C deduction. The interest and the maturity amount are fully tax-free under both regimes. That is why the post-tax return beats most FDs for people in the higher slabs.
Lock-in, withdrawals and extension
The account matures after 15 full financial years. Partial withdrawals are allowed from the 7th year. After maturity you can extend in blocks of 5 years, with or without fresh deposits. The balance keeps earning interest either way.
