The pure math, 15-year horizon
A ₹1.5 lakh/year contribution at 7.1% (PPF) for 15 years builds roughly ₹40 lakh — fully tax-free at maturity. The same ₹1.5 lakh/year in ELSS at 12% builds roughly ₹62 lakh pre-tax, ~₹60 lakh after LTCG. Equity ELSS comes out ~50% ahead on return.
The catch: equity returns are not linear. A 30% drawdown in years 7-9 is a real possibility — and emotionally hard to ride through. PPF's certainty has behavioural value, not just mathematical.
The right answer is usually 'both'
Most planners suggest allocating part of the 80C limit to PPF (the safety/certainty leg) and part to ELSS (the growth leg). A 50-50 split is a reasonable default for an investor in their 30s; the ELSS share can be higher for younger investors with longer horizons.
PPF also serves as the EEE-tax debt portion of your overall portfolio — useful for asset-allocation reasons beyond just 80C.
Liquidity matters more than people think
PPF allows partial withdrawal only from year 7, capped at 50% of the year-4 balance. ELSS becomes fully liquid 3 years after each instalment. If you might need the money before 15 years for an emergency or goal, the ELSS liquidity is materially valuable.
