PPF runs in 15-year blocks, extendable in 5-year steps. The rate is set by the government each quarter (currently 7.1%). The ₹1.5 lakh yearly cap is also your 80C limit — deposits are deductible, interest is tax-free, and so is the maturity. That EEE status is what makes it special.

the boring math behind it

three honest answers.

what is PPF?

The Public Provident Fund is a government savings scheme with a 15-year lock-in. You can put in ₹500 to ₹1.5 lakh a year, the government pays a set interest rate (revised quarterly), and interest compounds annually. It's about as safe as an Indian investment gets — sovereign-backed.

Its superpower is tax. PPF is EEE: deposits qualify for 80C deduction, the interest is tax-free, and so is the final maturity. Very few instruments are tax-free all the way through.

how does the math work?

Each year's deposit compounds until maturity. For equal yearly deposits at the start of each year:

M = P × ((1 + r)^n − 1) ÷ r × (1 + r)

Where P is the yearly deposit, r is the rate, and n is the number of years. Real PPF interest is figured on the lowest monthly balance, so deposit early in April each year to squeeze out a little extra.

PPF or ELSS?

Both save tax under 80C, but they're opposite animals. PPF is safe, fixed, tax-free, 15-year lock-in. ELSS is equity — higher potential return, market risk, and only a 3-year lock-in. PPF protects; ELSS grows.

Most sensible portfolios hold some of each. Try the ELSS calculator, or ask Archita what split fits your risk and your tax.
