Equity Linked Savings Scheme (ELSS) Calculator: Returns, Tax Saving and Lock-in

Growth uses the same engines as the CalcMate SIP and lumpsum calculators: a SIP instalment is invested at the start of each month at a monthly rate of the annual return divided by 12, and a lumpsum compounds once a year. The return is an assumption you choose; ELSS funds invest mainly in shares and their value can fall.

Tax saving applies only in the old regime. There, ELSS investments count towards the Section 80C deduction, which is capped at ₹1,50,000 per financial year in total, shared with EPF, PPF, life insurance premiums, home loan principal and other eligible items. Enter those other investments and the calculator uses only the room that is left. The tax saved is the deduction multiplied by your slab rate, plus 4% health and education cess. Under the new regime, which applies unless you opt out, there is no Section 80C deduction and the tax saved is zero.

For a SIP, each year's twelve instalments are treated as one financial year's investment, so the deduction can be claimed every year the SIP runs, up to the cap. A lumpsum gives a deduction only in the year it is invested, so investing more than ₹1,50,000 in one go does not bring extra tax benefit.

Every ELSS investment is locked for 3 years from its own date. For a SIP that means each instalment unlocks separately: the January instalment of one year becomes free in January three years later. So at the end of a SIP, the instalments from roughly the last 3 years are still locked, and the calculator shows their value and when the last one frees up.

Gains on equity funds held for more than 12 months are long-term capital gains, taxed at 12.5% on the amount above ₹1,25,000 in a financial year, plus cess. The calculator shows an indicative figure for the part that is unlocked at the end, as if it were all sold in one financial year with no other equity gains that year. Spreading redemptions over several years can reduce it.

Worked example: a ₹12,500 monthly SIP puts exactly ₹1,50,000 into ELSS each financial year. At the 30% old-regime slab, with no other 80C investments, that saves ₹46,800 a year in tax (₹1,50,000 x 30% x 1.04). If EPF already uses ₹1,00,000 of the limit, only ₹50,000 of the ELSS counts and the saving drops to ₹15,600.

ELSS is not the only 80C option, and it is the riskiest one. It has the shortest lock-in, 3 years against 15 for PPF, but its return is market-linked and its gains are taxed, while PPF pays a government-set rate that is fully tax-free. Before investing for the deduction, check which regime you will actually file under with the Income Tax Calculator and the old vs new regime guide.
