ELSS Calculator India — Tax-Saving Fund Returns & Section 80C 2026
ELSS (Equity Linked Savings Scheme) is the only mutual fund category that qualifies for Section 80C deduction — and that deduction is available only under the old tax regime. Since FY 2024-25, the new tax regime is the default for all taxpayers and allows no Section 80C deductions whatsoever. If you have defaulted to or switched to the new regime, your ELSS SIP earns equity returns normally but provides zero tax saving. For a 30% bracket investor in the old regime, investing ₹12,500/month (₹1.5 lakh/year — the Section 80C limit) saves ₹46,800 in income tax annually under the old regime. That is a guaranteed 31.2% return on that ₹1.5L before the fund earns a single rupee of market return.
The 3-year lock-in in ELSS applies per instalment, not per investment. Each monthly SIP payment is locked for exactly 3 years from its own allotment date. This means a 12-month ELSS SIP results in 12 different unlock dates spread across the fourth year — you cannot redeem the full investment on the third anniversary of your first payment. At redemption, gains qualify as Long-Term Capital Gains under Section 112A at 12.5% on gains above ₹1.25 lakh per financial year, effective 23 July 2024 (Finance Act 2024, no indexation). STCG at 20% (Section 111A) does not apply to ELSS because the mandatory 3-year lock-in guarantees all holdings are long-term. Budget 2026 made no changes to these rates. Use the Income Tax Calculator to model your exact 80C saving, and the PPF Calculator to compare ELSS equity returns against the PPF's EEE status over the same horizon.

How ELSS Works — SIP Formula, Per-Instalment Lock-in, and LTCG at Exit
ELSS uses the standard SIP compounding formula: FV = P × [((1+r)^n − 1) / r] × (1+r), where P is the monthly instalment, r is the monthly return rate (annual rate ÷ 12), and n is the number of months. The calculator above applies this formula with your inputs. What distinguishes ELSS from a plain equity SIP is what happens at the other end: the lock-in and the LTCG calculation.
The per-instalment lock-in: Each monthly SIP instalment is allotted units at that month's NAV. The 3-year lock-in clock starts from the allotment date of each specific instalment — not from the date you started the SIP. If you began an ELSS SIP in July 2023, the July 2023 instalment unlocks in July 2026, the August 2023 instalment unlocks in August 2026, and so on. Redeeming the entire ELSS portfolio on 1 July 2026 would be a mistake — only the July 2023 units are unlocked at that point. All later instalments remain locked.
LTCG at exit — Section 112A, effective 23 July 2024: Since the 3-year lock-in guarantees all ELSS units are held over 12 months, all gains are Long-Term Capital Gains. Under Section 112A (Finance Act 2024), LTCG on equity mutual funds above ₹1.25 lakh per financial year is taxed at 12.5% (no indexation). The first ₹1.25 lakh of LTCG per year is exempt. STCG under Section 111A (20%) cannot arise from ELSS redemptions because the lock-in prevents units from being held under 12 months. Budget 2026 made no changes to these rates — they apply to FY 2025-26 and FY 2026-27.
Worked example — ₹12,500/month for 5 years at 14%: Total invested: ₹7.5L. Estimated corpus at 5 years: approximately ₹10.9L. Gains: ₹3.4L. LTCG tax: 12.5% on (₹3.4L − ₹1.25L) = 12.5% on ₹2.15L = ₹26,875. Post-tax corpus: approximately ₹10.6L. Annual 80C tax savings over 5 years: ₹46,800 × 5 = ₹2.34L (30% bracket, old regime). Net-of-tax corpus after factoring in tax savings: approximately ₹10.6L + ₹2.34L benefit already received = very competitive post-tax outcome.
Three ELSS Decisions That Reveal What the 80C Benefit Really Costs and Returns
Scenario 1: Ravi, 32, 30% bracket in old regime — ELSS as the primary 80C instrument
Ravi invests ₹12,500/month in ELSS for 15 years at 14% annual return. Total invested: ₹22.5L. Corpus at 15 years: approximately ₹1.01 crore. Total gains: ₹78.6L. LTCG tax across all redemption years (assuming ₹1.25L exempt per year): his annual redemptions produce LTCG well above the exemption — tax of approximately ₹9.8L over the redemption phase. Post-tax corpus: approximately ₹91.2L.
Over the same 15 years, Ravi saved ₹46,800/year in income tax (30% of ₹1.5L): total tax saved = ₹7.02L. These savings, if reinvested, grow at the same rate. Net position: ELSS delivered equity market returns, the 80C deduction offset a significant portion of the eventual LTCG tax cost, and the post-tax outcome substantially outperforms PPF (₹40.7L fully exempt at 7.1% for same ₹1.5L/year).
Scenario 2: Shalini, 28, switches to new regime in FY 2025-26 — the ELSS orphan problem
Shalini had been running a ₹12,500/month ELSS SIP for 3 years in the old regime, claiming ₹46,800/year in tax savings. In April 2025, her employer defaults her to the new tax regime. She does not notice — and continues her ELSS SIP for another 2 years.
Under the new tax regime, Section 80C deductions do not exist. Her ELSS SIP continues to generate equity market returns — but zero tax saving. She has been paying into a locked-up equity fund for 2 years with no tax benefit that she was not aware of losing. What should Shalini do? First, confirm which regime she is in with her employer. If she wants tax benefits, she must opt out of the new regime. If she stays in the new regime, she can continue the ELSS (returns are identical) but should also consider a plain diversified equity fund with no lock-in — giving her the same market exposure with more flexibility.
Scenario 3: The ₹1.25L LTCG exemption — three investors at different redemption amounts
All three are redeeming ELSS in FY 2026-27. All gains are long-term (3+ years held). Under Section 112A, ₹1.25 lakh of LTCG per financial year is exempt.
- Investor A — gains of ₹1.10L: Fully within the exemption. LTCG tax = ₹0.
- Investor B — gains of ₹2.50L: Tax = 12.5% × (₹2.50L − ₹1.25L) = 12.5% × ₹1.25L = ₹15,625.
- Investor C — gains of ₹6.00L: Tax = 12.5% × (₹6.00L − ₹1.25L) = 12.5% × ₹4.75L = ₹59,375.
Practical implication: if your total ELSS corpus has accumulated large gains and you plan to redeem, spreading redemptions across financial years to stay near the ₹1.25L exemption each year is a tax-efficient strategy. Redeem in March (end of one FY) and again in April (start of the next FY) — and use two exemptions in quick succession.
ELSS Rules — Section 80C, Section 112A, Old Regime Requirement & SEBI Framework
Old regime only for Section 80C: The Section 80C deduction for ELSS investments is available exclusively under the old tax regime. The new tax regime (default since FY 2024-25 under Section 115BAC) does not allow any Chapter VI-A deductions including Section 80C. If you are in the new regime, your ELSS investment earns returns but provides no tax benefit. The ₹1.5 lakh Section 80C limit is shared across all eligible instruments: EPF employee contribution, PPF, LIC premiums, ELSS, NSC, home loan principal repayment, and tuition fees for up to two children.
ELSS definition and SEBI framework: ELSS is defined under SEBI (Mutual Funds) Regulations, 1996 and SEBI's October 2017 circular on mutual fund categorisation (SEBI/HO/IMD/DF3/CIR/P/2017/114). SEBI requires ELSS funds to maintain at least 80% of assets in equity and equity-related instruments, with a 3-year statutory lock-in per unit. Only one ELSS fund per scheme category per AMC is permitted. ELSS is the only open-ended equity category with a tax benefit — all other equity categories (large cap, mid cap, flexi cap, etc.) do not qualify for Section 80C.
LTCG — Section 112A, Finance Act 2024: Effective 23 July 2024, long-term capital gains on equity mutual fund units (held over 12 months) are taxed at 12.5% on the amount exceeding ₹1.25 lakh per financial year. There is no indexation benefit. Previously (before 23 July 2024), the rate was 10% above ₹1 lakh. Budget 2026 made no further changes — these rates apply to FY 2025-26 and FY 2026-27.
STCG — Section 111A: Short-term capital gains on equity mutual funds (held under 12 months) are taxed at 20% (raised from 15% by Finance Act 2024, effective 23 July 2024). STCG cannot arise from ELSS redemptions because the statutory 3-year lock-in prevents units from being held under 12 months. Budget 2026 made no changes to the STCG rate.
Each SIP instalment — independent holding period: For LTCG/STCG determination in any mutual fund, each SIP instalment is treated as a separate purchase with its own holding period. In a regular equity fund, one redemption can produce a mix of LTCG (instalments bought over 12 months ago) and STCG (recent instalments). In ELSS, this distinction is moot because the 3-year minimum lock-in guarantees all units are always long-term.
AMFI registration: All ELSS funds are sold through AMFI-registered mutual fund distributors or directly via fund houses. You can invest in ELSS via direct plan (lower TER, no commission) through the fund house's website or platforms like MF Central, or via regular plan through a distributor or bank. The direct plan TER for ELSS funds typically runs 0.5–1.0% lower than the regular plan.
What Most ELSS Investors Get Wrong
Continuing ELSS SIP without checking the regime. Since FY 2024-25, the new tax regime is the default. An investor who did not explicitly opt for the old regime at the start of the year has no 80C benefit — but may not realise it. Check your Form 16 Part B: it shows whether your employer applied old or new regime deductions. If 80C is not listed, you are in the new regime and your ELSS provides no tax saving.
Assuming the 3-year lock-in clock starts from the SIP registration date. It does not. It starts from each instalment's individual allotment date. If you registered your SIP on 1 January 2023, you can redeem the 1 January 2023 instalment on 1 January 2026 — but the 1 February 2023 instalment is only unlocked on 1 February 2026, and so on for all 12 months of that first year. Attempting to fully redeem an ELSS SIP exactly 3 years after the registration date will be partially rejected by the fund house.
Treating ELSS as entirely tax-free. ELSS provides a Section 80C deduction on investment — it does not provide tax-free maturity like PPF. Gains above ₹1.25 lakh per FY at redemption are taxed at 12.5% under Section 112A. The distinction matters: a 30% bracket investor saves 31.2% on the investment amount today but pays 12.5% on net gains at redemption. The net effect is still strongly positive, but it is not EEE status.
Comparing ELSS CAGR to PPF without adjusting for LTCG. Fund houses advertise ELSS 15-year CAGR of 14–16%. PPF offers 7.1% with full EEE status. The correct comparison is: ELSS 14% CAGR minus effective LTCG rate at exit vs PPF 7.1% with zero tax. For most investors with moderate corpus sizes (gains under ₹5–6L total at redemption), ELSS still wins significantly — but the comparison should be done on a net-of-tax basis.
Investing more than ₹1.5L in ELSS for 80C purposes. The Section 80C deduction caps at ₹1.5 lakh across all eligible instruments combined, including EPF. If your EPF contribution already consumes ₹1 lakh of this limit, investing ₹1.5L in ELSS gives only ₹50,000 in actual 80C deduction — not ₹1.5L. Calculate your remaining 80C headroom (₹1.5L minus EPF employee share minus LIC minus any other 80C items) before setting the ELSS SIP amount.
Frequently Asked Questions
What is ELSS and how does it save tax?
ELSS (Equity Linked Savings Scheme) is a type of mutual fund that qualifies for tax deduction under Section 80C of the Income Tax Act. Investments up to ₹1.5 lakh per year in ELSS reduce your taxable income by the same amount — but only if you are in the old tax regime. For someone in the 30% tax bracket under the old regime, this saves up to ₹46,800 in income tax annually (30% of ₹1.5L + 4% cess). If you are in the new tax regime (the default since FY 2024-25), ELSS provides no Section 80C benefit.
What is the lock-in period for ELSS?
ELSS has a mandatory lock-in of 3 years per instalment, measured from each unit's allotment date. Each SIP instalment is individually locked. An instalment allotted in January 2024 unlocks in January 2027; one allotted in February 2024 unlocks in February 2027. You cannot redeem the entire ELSS portfolio on the 3-year anniversary of your first instalment — only units allotted 3+ years ago can be redeemed. ELSS has the shortest statutory lock-in among all Section 80C instruments (PPF: 15 years, NSC: 5 years, tax-saving FD: 5 years).
Is ELSS return tax-free at maturity?
No. ELSS does not have EEE (Exempt-Exempt-Exempt) status like PPF. At redemption, Long-Term Capital Gains (LTCG) are taxed under Section 112A at 12.5% on gains above ₹1.25 lakh per financial year, effective 23 July 2024 (Finance Act 2024). The first ₹1.25 lakh of LTCG each year is exempt. STCG (Section 111A, 20%) cannot arise from ELSS because the 3-year lock-in ensures all holdings are long-term. Budget 2026 made no changes to these rates.
ELSS vs PPF — which is better for tax saving in India?
Both instruments qualify for Section 80C deduction (old regime only). ELSS has historically delivered 12–16% CAGR over long periods vs PPF's 7.1% (current rate, unchanged since the April–June 2020 quarter). ELSS has a 3-year lock-in vs PPF's 15 years. PPF maturity is completely tax-free (EEE status); ELSS gains above ₹1.25L/year are taxed at 12.5% under Section 112A. On a net-of-tax basis over 15 years at maximum ₹1.5L/year: ELSS at 14% gives approximately ₹1.01 crore pre-tax vs PPF's ₹40.7L tax-free. Even after LTCG, ELSS wins significantly for investors comfortable with equity volatility.
Is ELSS available under the new tax regime?
ELSS mutual funds are available to everyone regardless of tax regime — you can buy and hold ELSS units even as a new-regime taxpayer. However, the Section 80C deduction (up to ₹1.5L) does not apply in the new tax regime. The new regime, which is the default since FY 2024-25, allows no Chapter VI-A deductions including Section 80C. As a new-regime investor, your ELSS earns the same equity market returns as any other equity fund — but you receive zero tax saving on the investment amount.
What happens to my ongoing ELSS SIP if I switch to the new tax regime?
Your SIP continues running and units continue to be allotted normally. The ELSS fund is not affected by your tax regime choice. What changes is: you no longer receive a Section 80C deduction on the new contributions. Units already allotted before your regime switch retain the 80C deduction for those years (if you filed under the old regime those years). From the switch year onwards, no 80C benefit. Consider switching to a direct-plan diversified equity fund (same returns, no lock-in) for any incremental investment beyond what is already running.
Can I invest more than ₹1.5 lakh in ELSS in a year?
Yes, you can invest any amount in ELSS without an upper limit. However, the Section 80C deduction is capped at ₹1.5 lakh per year across all 80C instruments combined — EPF employee contribution, PPF, LIC, ELSS, NSC, home loan principal, and tuition fees. Investments above your remaining 80C headroom get no additional tax deduction but earn normal equity market returns. For amounts beyond the 80C limit, a plain equity mutual fund with no lock-in is usually preferable.
What return should I use for ELSS projections?
Use 12% for conservative planning, 14% for moderate estimates. The ELSS category has delivered approximately 12–16% CAGR over 10–15 year periods in aggregate, with the top-performing funds reaching higher returns. Do not use more than 16% — equity returns are highly path-dependent and extended periods of below-average returns (2000–2003, 2008–2009, 2020) occur regularly. Past performance does not guarantee future returns. For planning purposes, the difference between 12% and 14% CAGR on ₹12,500/month over 15 years is approximately ₹25 lakhs in final corpus — so the assumption matters.
