PPF
Definition
Public Provident Fund — a government-backed 15-year savings scheme with sovereign guarantee, EEE tax status (contributions, interest, and maturity all exempt), and interest rate set quarterly by the government.
Detailed Explanation
Key features: Tenure is 15 years (extendable by 5-year blocks). Minimum deposit: Rs.500/year. Maximum: Rs.1.5 lakh/year. You can make up to 12 deposits per year. The interest rate is revised quarterly by the Government (currently 7.1% p.a., compounded annually). Interest is calculated on the lowest balance between the 5th and last day of each month — so always deposit before the 5th.
Liquidity: Partial withdrawal is allowed from the 7th financial year (up to 50% of balance at end of 4th year or preceding year, whichever is lower). Loans against PPF balance are available from the 3rd to 6th year.
PPF is ideal for: Conservative investors, those in higher tax brackets (where FD interest is heavily taxed), parents opening accounts for minors, and anyone wanting a risk-free retirement corpus alongside EPF.
The main downside: The 15-year lock-in makes it inflexible. Returns (7.1%) are lower than historical equity returns (10%–15%). For young investors with a higher risk appetite, ELSS or equity mutual funds may be more suitable.
Where: P = Annual deposit, r = Annual interest rate, n = Number of years
Example
Amit deposits Rs.1.5 lakh every year in PPF for 15 years. Total investment: Rs.22.5 lakh. At 7.1% compounded annually, his maturity amount is approximately Rs.40.68 lakh — completely tax-free. If he extends for another 5 years (total 20 years), the corpus grows to approximately Rs.66.5 lakh.
