ELSS vs PPF: same ₹1.5 lakh, two completely different products

Both fit inside the same ₹1,50,000 Section 80C ceiling, and most people meet them as a single question at the end of the financial year: which one do I put the money in? They are not close substitutes. One is a government savings account with a fifteen-year door on it; the other is an equity fund with a three-year door. The choice is really about when you need the money and how much volatility you can hold.

The seven differences that decide it

• What it holds. ELSS is an equity fund — at least 80% in Indian shares, by SEBI rule. PPF is a government-notified rate paid on your deposit; nothing is invested on your behalf.
• Return. ELSS gets whatever the market does, with no floor and no ceiling. PPF was 7.1% for the Apr–Jun 2026 quarter and is re-notified every quarter, applying to the whole balance rather than just new deposits.
• Lock-in. Three years for ELSS, per instalment. Fifteen for PPF, extendable in five-year blocks. Both of those numbers are misread, which is the next section.
• Risk of loss. Real for ELSS, and it has happened over three-year windows. None for PPF in nominal terms.
• Tax going in. Identical, and identically conditional: an 80C deduction that exists only on the old regime.
• Tax coming out. ELSS pays 12.5% on long-term gains above ₹1,25,000 a year, like any equity fund. PPF pays nothing — interest and maturity are both exempt.
• The yearly cap. PPF has a hard ₹1,50,000 account limit. ELSS has none: 80C caps the deduction, not how much you may invest.

Two of those do most of the work.

The lock-in numbers do not mean what they look like

ELSS's "three years" is per instalment, not per account. A SIP started in April 2026 has twelve separate three-year clocks, and the instalment you paid in March 2027 is not free until March 2030. People who plan to redeem the whole thing on the third anniversary find most of it still locked.

PPF's "fifteen years" is longer than it reads. The account matures at the end of the fifteenth financial year after the one it was opened in, so an account opened in March 2026 runs to 1 April 2042 — sixteen years and a few days. From year seven you may withdraw part of it, and from year three you may borrow against it, so it is not quite the sealed box it appears to be.

Where the tax break actually lives

Neither instrument's headline benefit survives the new tax regime, which is the default. Section 80C does not exist there. If you have not opted into the old regime, both of these are ordinary investments and the comparison becomes:

• an equity fund with a three-year lock-in and 12.5% tax on its gains, versus
• a 7.1% deposit that is still tax-free at maturity.

On the new regime the ELSS lock-in buys you nothing at all — a plain flexi-cap or index fund does the same job without the door. PPF keeps its exemption regardless of regime, so it survives the switch with more of its case intact than ELSS does.

What the return gap is worth after tax

Run it rather than argue about it. The comparison below takes the same yearly contribution and puts PPF's tax-free maturity next to a fund's value after the 12.5% long-term rate:

Two things the arithmetic will show. Over fifteen years the equity assumption dominates everything else — the gap between 10% and 12% swamps the entire tax difference. And PPF's exemption is worth more than it looks: a tax-free 7.1% is roughly an 8.3% pre-tax return for someone at the 30% slab on the old regime, which is why "only 7.1%" understates it.

How to decide, in one paragraph

If the money is for something inside ten years — a house deposit, a wedding, an education bill — the fifteen-year lock rules PPF out and the equity risk rules ELSS out too; use a short-duration or hybrid fund with no lock-in at all. If it is genuinely retirement money and you are on the old regime, the honest answer is usually both: PPF for the part of your portfolio that must not fall, ELSS for the part that should grow, with the split set by your existing equity exposure rather than by the tax section they share. If you are on the new regime, PPF still makes sense as a debt allocation and ELSS almost never does — buy the same equity without the lock-in.

What people get wrong

• Treating ELSS as a three-year product. Three years is the minimum, not the plan. Equity held for three years is a coin toss; the ELSS case rests on holding it for ten. The lock-in is a floor on your patience, not a promise about returns.
• Believing PPF's rate is fixed. It is notified quarterly and applies to the whole balance, not just new deposits. It has been 7.1% since April 2020 and ranged from 7% to 8.8% in the two decades before.
• Investing ₹1.5 lakh in each and expecting a ₹3 lakh deduction. The 80C ceiling is ₹1,50,000 across everything in the section — EPF, life insurance premiums, tuition fees, home-loan principal and both of these.
• Opening the PPF account in March. Interest is computed on the lowest balance between the 5th and the month end, so a deposit made before 5 April earns a full year's interest and one made on 31 March earns none of it.

Key takeaway

They share a tax section and nothing else. On the old regime the answer is usually both — PPF for the money that must not fall, ELSS for the money that should grow, split by your existing equity exposure rather than by the ₹1.5 lakh ceiling. On the new regime, where 80C does not exist, ELSS loses its whole reason to have a lock-in and a plain equity fund does the same job better; PPF keeps its exemption and survives the switch. And for anything you need inside ten years, neither is the answer.
