PPF Calculator — Public Provident Fund Maturity

PPF is India's most loved safe investment — zero risk, tax-free returns, government-backed guarantee. See how your deposits grow.

Corrected 29 August 2026. An earlier version of this page excluded target variable pay from both received cash and taxable salary, which understated income tax. Figures are recalculated under model PS-A3. What changed →

Short answer: PPF pays 7.1% a year, compounded annually, tax-free at every stage, with a 15-year lock-in and a ₹1.5 lakh annual cap. Depositing the full ₹1.5 lakh every year for 15 years builds a corpus of about ₹40.68 lakh, none of which is taxed on withdrawal.

Why PPF Remains India's Favourite Investment

PPF has been running since 1968 — over 55 years of unbroken service. The reason it survives is simple: it just works. You put money in, it grows at a guaranteed rate, and when it matures, you get everything back without paying a single rupee in tax. This EEE (Exempt-Exempt-Exempt) status is incredibly rare — your investment gets 80C deduction, interest is tax-free, and maturity amount is fully exempt.

At 7.1%, if you invest the maximum ₹1.5 lakh every year for 15 years, your total deposit of ₹22.5 lakh grows to approximately ₹40.68 lakh. That is ₹18.18 lakh in interest — completely tax-free. No mutual fund, FD, or any other instrument can guarantee that combination of safety and tax efficiency.

💡 The April 5th Rule: PPF interest is calculated on the minimum balance between the 5th and last day of each month. Deposit before April 5th to earn interest for that month. Depositing on April 6th means losing one full month of interest — about ₹887 at the ₹1.5 lakh limit, which compounds to roughly ₹22,000 of lost interest over 15 years.
⚠️ Disclaimer: PPF interest rate is set quarterly by the government and may change. Currently 7.1% for Q2 FY 2026-27. Always verify at your bank or post office.
