🇮🇳 ELSS Calculator

An Equity Linked Savings Scheme, or ELSS, is India's tax-saving mutual fund: equity exposure with a Section 80C deduction up to ₹1.5 lakh per year and the shortest lock-in of any tax-saving option at just three years per installment. This calculator projects what a monthly ELSS SIP could grow into, so you can weigh the tax saving today against the wealth compounding tomorrow.

How to Use This Calculator

The Formula

Each SIP installment compounds for its own remaining term, which is the future value of an annuity due:

The lock-in applies per installment, not per account: every SIP payment is locked for three years from its own date. Gains are taxed as long-term capital gains at 12.5 percent on amounts above ₹1.25 lakh per financial year.

Worked Example

Priya invests ₹10,000 per month for 10 years at an assumed 12 percent annual return. Her total investment is ₹12,00,000. Compounding monthly, the projected maturity value is ₹23,23,391, of which ₹11,23,391 is gains. Along the way she claims up to ₹1.20 lakh per year under Section 80C, saving roughly ₹37,440 annually in tax if she is in the 30 percent slab plus surcharge math. The three-year lock-in keeps her invested through market dips she might otherwise have fled.

Tips for ELSS Investors

Prefer SIPs over lump sums for ELSS: twelve lock-ins expiring monthly after three years beats one giant lock-in, and rupee-cost averaging smooths entry prices. Do not redeem the day the lock-in ends unless you need the money; ELSS is an equity fund first and a tax product second, and compounding rewards the patient. Compare funds on 5-year rolling returns and downside capture, not last year's chart-topper. For a full deduction picture, pair this with our income tax calculator for India to see your slab.

Common Mistakes

The classic error is stopping the SIP after the first three years because "the lock-in is over." The lock-in ending is not a sell signal; it is simply the earliest exit date. Another is investing the full ₹1.5 lakh in March to "save tax" without checking whether the old regime even benefits you, since the new regime offers no 80C deduction at all. A third is assuming the projected return is promised: 12 percent is a planning assumption, and real equity returns arrive in lumps, with years of nothing followed by years of plenty.

ELSS vs PPF vs NSC

Against the Public Provident Fund's tax-free 7.1 percent and 15-year term, ELSS offers higher expected returns with market risk and a far shorter lock-in. Against the National Savings Certificate's 5-year guaranteed return, ELSS trades certainty for growth. For a young earner in a high slab who can tolerate volatility, ELSS usually wins on post-tax wealth; for someone who cannot watch a portfolio fall 20 percent without panic, the guaranteed options win on sleep. Match the product to your temperament, not just the math.

ELSS and the 80C Basket

Section 80C gives you one ₹1.5 lakh bucket shared across ELSS, PPF, NSC, EPF contributions, home-loan principal, children's tuition fees, and life insurance premiums. Most salaried earners fill half the bucket without trying: EPF deductions plus a home loan often cross ₹1 lakh. The strategic question is what fills the remainder, and ELSS usually wins that slot for anyone under 40 with equity tolerance.

The ordering logic is simple: fund the mandatory items first (EPF happens automatically), then allocate the leftover 80C room to the highest expected post-tax return, which is ELSS for long horizons. PPF suits the remainder only if you want guaranteed returns or have exhausted your risk appetite. One caution: do not invest extra in ELSS beyond the ₹1.5 lakh deduction purely for tax reasons; beyond the limit it is just another equity fund competing with flexi-caps on merit.

Track the basket yearly in March, not April. The investors who scramble in the last week buy whatever the distributor pushes; the ones who plan in April spread ₹12,500 monthly SIPs across the year. Same deduction, better averaging, zero stress. The 80C bucket rewards the calendar-conscious.

When ELSS Disappoints

ELSS has produced stretches that test every thesis. SIPs started at the 2007 peak spent years underwater; the three-year lock-in that normally prevents panic selling became a cage investors rattled. Anyone who began ELSS in 2018 watched the 2020 crash erase two years of gains in a month. The lock-in cuts both ways: it stops you from selling low, but it also stops you from reallocating when your thesis genuinely changes.

The honest framing is that ELSS returns are equity returns with a tax wrapper, not a separate asset class. Over rolling ten-year periods Indian equity SIPs have rarely disappointed, but three-year windows, exactly the lock-in length, have frequently shown flat or negative results. Invest money you will not need at the lock-in's end, and judge performance over seven-plus years.

The disappointment hedge is diversification across fund styles and continuing the SIP through the pain. Every great ELSS vintage was built by installments paid during scary headlines. The lock-in forces the behavior; your job is to choose funds worth being locked into, with consistent processes rather than star managers who might leave mid-lock-in.
