The Core Trade-Off
PPF offers guaranteed 7.1% tax-free returns with full capital safety. ELSS offers market-linked returns — historically 12–14% CAGR over 10+ years — but with equity volatility and a 3-year lock-in. Both qualify for Section 80C deduction up to ₹1.5 lakh per year.
The Numbers Over 10 Years
₹1.5 lakh invested annually for 10 years: PPF compounds to roughly ₹21.5 lakh (at 7.1%). Top ELSS funds have compounded the same amount to ₹34–40 lakh over 10-year periods. Even at conservative ELSS returns of 10%, the outcome (₹26 lakh) beats PPF.
When PPF Wins
PPF is the right choice when: (1) your investment horizon is under 5 years, (2) you are in a 30% tax bracket and need capital safety, (3) you are already sufficiently invested in equity. PPF and ELSS complement each other — the ideal 80C allocation often combines both.
