About the PPF Calculator
PPF (Public Provident Fund) is India's most popular tax-free long-term savings scheme, backed by a sovereign guarantee — meaning the principal and interest are guaranteed by the Government of India, not just a bank. Minimum deposit ₹500/year, maximum ₹1.5 lakh/year, tenure 15 years (extendable in 5-year blocks indefinitely). Open at any post office, SBI, PNB, ICICI, HDFC, Axis, BoB, Canara, or any nationalized bank.
Interest is calculated on the minimum balance between the 5th and end of each month, then credited at year-end. To maximize returns, deposit your full ₹1.5 lakh contribution before April 5th of every financial year — this small timing trick adds roughly ₹50,000 to your final corpus over a 15-year tenure compared to depositing at year-end. If you can't lump it in, deposit by the 5th of every month.
Tax-free compounding at 7.1% means ₹1.5L/year for 15 years grows to ~₹40.68 lakh, of which ₹18.18 lakh is pure interest — and you pay zero tax on it. PPF is one of the only EEE (Exempt-Exempt-Exempt) instruments left in India: contributions deductible under 80C, interest tax-free, maturity tax-free. Compare to FDs where 30%-bracket taxpayers lose roughly 30% of interest to tax — making post-tax FD return ~5% versus PPF's full 7.1%.
Strategic uses of PPF that most retail investors miss: (1) Open accounts in your spouse's and children's names — each account gets its own ₹1.5L limit, multiplying tax-free corpus building, though clubbing rules apply for minor children's interest. (2) Use PPF as the 'debt' allocation in your portfolio, freeing you to be more equity-aggressive elsewhere. (3) Take a loan against PPF (years 3–6, up to 25% of balance from the 2nd-preceding year) at just 1% above PPF rate, instead of breaking other investments.
What changes after 15 years: at maturity, you have three choices. (a) Withdraw the entire corpus tax-free. (b) Extend the account in 5-year blocks without contributions — the existing balance keeps earning the prevailing PPF rate. (c) Extend with fresh contributions for another 5 years. Option (c) is powerful: extending three times takes you to 30 years, and a ₹1.5L/year contribution for 30 years at 7.1% builds ₹1.55 crore tax-free. PPF rates have ranged from 7.1% to 12% historically; the government reviews quarterly. Even at the current floor of 7.1%, PPF beats most post-tax fixed-income alternatives for retail savers.
