ELSS vs PPF for the 80C wallet: Post-tax IRR comparison over a 15-year horizon

Every March, the same question crashes Indian inboxes: should the Rs 1.5 lakh Section 80C wallet go into Public Provident Fund (PPF) or an Equity Linked Savings Scheme (ELSS)? Headlines call it a debate between safety and growth, but the honest answer is a number — the post-tax internal rate of return (IRR) over a realistic holding period. For the 15-year PPF cycle that anchors most investors' planning, the math has shifted twice in the last two years: the Budget 2024 LTCG rework lifted the equity tax rate from 10% to 12.5% with a bigger Rs 1.25 lakh exemption, and the new tax regime (the default for FY 2025-26) silently switched off the 80C deduction itself. Both changes alter the wallet calculation more than most templated calculators reflect.

This pulse models a household running the maximum Rs 1.5 lakh annual contribution for the full 15-year PPF lock-in. PPF is fixed by government notification at 7.1% per annum for Q1 FY 2025-26 (Ministry of Finance Department of Economic Affairs), credited annually on the lowest balance between the 5th and the last day of the month — a quirk that rewards early-April lump sums. ELSS funds are governed by the SEBI Equity Linked Savings Scheme Rules 2005, which mandate at least 80% allocation to equity and a hard 3-year lock-in (the shortest of any 80C instrument). The briefing benchmark we model — 12% pre-tax compounded annual growth — sits roughly between the 15-year CAGRs of the Nifty 500 TRI and BSE 500 TRI as published by the AMFI Benchmark Index page, and broadly aligns with what large-cap and ELSS category averages have delivered through May 2026.

Side-by-Side Comparison

The table below sets out the structural features of the two instruments as they stand on 24 May 2026. The PPF rate is the rate notified for Q1 FY 2025-26; the small savings rate is reviewed quarterly under the Shyamala Gopinath formula linking it to G-Sec yields. The ELSS return assumption is a planning assumption, not a guarantee — past performance disclaimers from SEBI Mutual Fund Regulation 1996 apply.

For a Rs 1.5 lakh annual contribution made on 1 April each year (annuity-due), PPF grows to roughly Rs 40.7 lakh by the end of year 15 at 7.1% compounding. The same Rs 1.5 lakh into a Nifty 500-style ELSS at 12% pre-tax CAGR compounds to roughly Rs 55.9 lakh over 15 years. Three numbers matter here: contributions total Rs 22.5 lakh in both legs, the equity excess is Rs 15.2 lakh, and that gap is exactly what tax treatment will whittle down.

Tax Treatment

PPF sits in the rare exempt-exempt-exempt (EEE) bracket. Section 10(11) of the Income-tax Act 1961 exempts both interest accrued and the maturity corpus, and Section 80C allows the contribution itself as a deduction up to Rs 1.5 lakh (but only if the taxpayer has opted for the old regime under Section 115BAC). For a salaried individual in the 30% old-regime slab, the 80C deduction saves Rs 46,800 in tax (Rs 45,000 base plus 4% cess) each year — a meaningful first-year boost that effectively raises the headline PPF return.

ELSS straddles two boxes. The contribution qualifies under Section 80C, but the redemption proceeds are taxed as long-term capital gains under Section 112A. The Budget 2024 amendment, notified in the Finance (No.2) Act 2024 with effect from 23 July 2024, fixed the LTCG rate at 12.5% with an annual exemption of Rs 1.25 lakh per financial year per assessee (up from Rs 1 lakh under the earlier regime). No indexation is available for listed equity.

The table below models the post-tax corpus for a single bullet redemption at year 15. For ELSS, a phased redemption strategy that harvests the Rs 1.25 lakh exemption each year can reduce the tax leakage materially — we model that scenario separately at the end of this section.

A second-order point on the 80C deduction itself: in the new regime, neither PPF nor ELSS contributions are deductible. Section 115BAC(1A), as amended by Finance Act 2025, denies all Chapter VI-A deductions other than 80CCD(2) and 80JJAA. The Section 87A rebate has been raised to Rs 60,000 for income up to Rs 12 lakh in the new regime, while the old regime retains the older Rs 12,500 rebate up to Rs 5 lakh — for many middle-income earners, the new-regime headline saving now exceeds what 80C delivered under the old regime, which means the tax-arbitrage case for PPF or ELSS has weakened sharply.

A third nuance worth flagging: the surcharge cap in the new regime is 25% (versus 37% in the old regime). For a high-income taxpayer comparing the regimes, the effective marginal tax saving from 80C is no longer 30% plus surcharge — it caps at the old regime's marginal rate, while the new regime offers a flatter slab structure. The standard advice that ELSS "saves tax and grows your money" assumes a regime choice that fewer than half of FY 2025-26 filers are still making.

Who Should Pick Which

The table above does not answer the question by itself. The choice depends on which of five investor profiles fits, and each profile has a defensible reason that goes beyond a CAGR delta of three to four percentage points.

Profile 1: Old-regime taxpayer in the 30% slab with a steady income. This is the textbook ELSS case. The Rs 46,800 first-year tax saving lifts the effective ELSS return by roughly 2.5 percentage points in year one, and the 3-year lock-in is short enough to permit phased exits that harvest the Rs 1.25 lakh annual LTCG exemption. The trade-off is volatility — a 30-35% drawdown in year 14 of the 15-year window would savage the bullet-exit math.

Profile 2: New-regime taxpayer who wants forced equity discipline. Here the 80C deduction is off the table for both products, so the comparison reduces to pure post-tax return versus volatility tolerance. ELSS still beats PPF on planning numbers, and the 3-year lock-in acts as a behavioural commitment device — useful for first-time equity investors who panic-sell during corrections. Our SIP calculator lets you stress-test the corpus under different return assumptions.

Profile 3: Retiree or conservative investor in any slab. PPF wins on three counts: sovereign guarantee (no NAV risk), predictable cash flow once the loan or partial withdrawal facility kicks in from year 3 and year 7 respectively, and EEE status that simplifies tax filing in retirement. The 7.1% sovereign-backed rate is comfortably above the 12-month RBI repo rate of 5.50% (April 2026 MPC decision), and small savings rates have not been cut in any of the last six quarterly reviews.

Profile 4: Goal-based investor with a sub-7-year horizon. Neither instrument is a great fit. PPF needs 15 years for the EEE benefit, and ELSS at a 3-year lock-in still exposes the corpus to equity volatility on the day the goal hits. For sub-7-year goals, a hybrid of debt mutual funds and arbitrage funds (covered in our SEBI debt MF PRC matrix primer) often dominates.

Profile 5: NRI investor. NRIs cannot open fresh PPF accounts under the PPF Scheme 2019 amendment (notification dated 12 December 2019), and existing accounts opened pre-NRI status must run to maturity without extension. ELSS remains accessible via the NRO/NRE route, with TDS at 12.5% on LTCG. For most NRI portfolios, ELSS is the de facto Section 80C instrument when the taxpayer files an Indian return under the old regime.

A rule of thumb that holds across profiles: if the household's equity allocation across all goals is below 40%, ELSS is the marginal Rs 1.5 lakh that pushes the portfolio toward its strategic asset allocation. If equity is already above 70% of household financial assets, PPF is the rebalancer that adds duration-free, sovereign-backed debt without crowding out other goals. Our ELSS calculator and PPF calculator let you side-by-side the two with your own return and tax inputs.

The Risk-Adjusted View: Sharpe, Sequence, and the 15-Year Drawdown

A pure IRR comparison hides risk. The Nifty 500 TRI standard deviation over the last 15 years (FY 2010-11 to FY 2024-25) clocked roughly 18-19% per annum on AMFI-published return data, against effectively zero for PPF. If we use the 10-year G-Sec yield of approximately 6.85% (RBI Weekly Statistical Supplement, week ending 16 May 2026) as the risk-free rate, the Sharpe ratio for the ELSS scenario at 12% return and 18% volatility comes to roughly 0.29 — modest by global equity standards.

Sequence-of-returns risk matters too. An investor who started SIPs in 2008 and exited in 2013 saw a 5-year post-tax IRR of less than 4% on most large-cap funds, despite a long-run CAGR closer to 11%. PPF carries no such sequencing risk: the rate may change quarterly, but the corpus value does not move sideways. For the 15-year horizon, three calendar quarters of equity weakness in years 13-15 can shave 200-400 basis points off the realised IRR — which is why phased redemptions starting in year 12 dominate bullet exits at maturity.

A practical hedge: investors with the temperament for equity but the calendar of a goal-bound saver often run a 50:50 ELSS-PPF split. The blended planning IRR comes to roughly 9% post-tax, with about half the volatility of pure ELSS. That hybrid also gives the household two separate 80C levers, which helps if income or marginal rate changes mid-cycle.

FAQ

Can I claim 80C deduction for both PPF and ELSS in the same financial year?

Yes — the Rs 1.5 lakh ceiling under Section 80C is across all eligible instruments combined, not per instrument. Splitting the wallet between PPF and ELSS is a common strategy under the old regime; it changes nothing in the new regime, where the deduction is denied.

Is the LTCG exemption of Rs 1.25 lakh available every year for ELSS phased redemptions?

Yes, the Rs 1.25 lakh exemption under Section 112A is per assessee per financial year and resets every 1 April. Staggering ELSS redemptions across multiple financial years is the cleanest way to harvest the exemption legally.

What happens if I miss a PPF deposit in any year?

The account is treated as discontinued and reactivation requires a Rs 50 penalty plus a Rs 500 minimum deposit per defaulted year, under Rule 4 of the PPF Scheme 2019. Interest continues to accrue on the existing balance during the dormant period, but no fresh loans or partial withdrawals are allowed until the account is regularised.

Can I extend the PPF account beyond 15 years?

Yes, in 5-year blocks. The first extension can be opted with or without further contributions, and the choice has to be made within one year of maturity by submitting Form H. Without an active election, the account is treated as extended without further contributions and continues to earn the prevailing rate.

Does the LTCG tax on ELSS apply if I redeem after exactly 3 years?

Yes. The 3-year period is only the SEBI lock-in. The capital gains classification still follows the general rule for listed equity under Section 2(42A) — gains are long-term if held over 12 months, which is automatically satisfied at the 3-year mark.

How does the new regime change the ELSS investment case?

The 80C deduction is denied in the new regime, so ELSS becomes a pure investment decision based on post-tax return and risk tolerance rather than a tax-saving instrument. For new-regime taxpayers, a regular non-ELSS equity fund without a 3-year lock-in often dominates ELSS for the same risk-return profile.

What is the post-tax IRR of EPF for comparison?

EPF earned 8.25% for FY 2024-25 (EPFO Central Board declaration, December 2024). Employee contributions up to Rs 2.5 lakh per year and the matching employer contributions remain EEE, making EPF effectively the highest-yielding EEE instrument for salaried employees — but it is not optional in the same way PPF or ELSS are.

The 80C wallet decision, distilled

The spreadsheet answer is that ELSS post-tax IRR of roughly 10.9% beats PPF's 7.1% by about 380 basis points over a 15-year cycle, generating Rs 11-12 lakh extra wealth on a Rs 22.5 lakh contribution. The behavioural answer is that the 380 basis points come bundled with 18% annual volatility, drawdowns of 30-40% in the worst rolling 3-year windows, and sequencing risk that can compress the realised IRR if the exit lands in a bear market. Investors who can hold through both 2008 and 2020-style shocks deserve the equity premium; those who cannot are better served by the sovereign-backed certainty of PPF. The honest 80C wallet, for households still on the old regime, is usually a deliberate split — not a winner-take-all bet on either side.

For a household running the calculation today on the new regime, the most important number is not the IRR delta — it is that the 80C deduction has been removed entirely, which means the choice is now a pure investment decision unmoored from tax arbitrage. The right framing then becomes: does this Rs 1.5 lakh per year belong in the household's equity bucket or its sovereign-debt bucket? That answer rarely depends on the wrapper, and almost always on the asset allocation the household already has.
