What makes ELSS different
An Equity Linked Savings Scheme is a diversified equity mutual fund with two features bolted on: investments qualify for a deduction under section 80C, and every unit is locked for three years from the date it was bought.
That is the whole difference. The portfolio is equity, the risk is equity, and the return is whatever the fund manager achieves. The tax break and the lock-in are rules wrapped around an ordinary equity fund.
Among 80C options, three years is the shortest lock-in available. A tax-saving fixed deposit locks money for five years, PPF for fifteen. That is the usual argument in ELSS's favour — along with the fact that it is the only 80C instrument whose returns are driven by equity markets.
Note that the 80C deduction only exists under the old tax regime. If you have moved to the new regime, ELSS is still a perfectly good equity fund, but it carries no tax advantage over any other, and the lock-in becomes a cost with nothing bought by it.
How the lock-in actually works with a SIP
This catches people out. The three years runs from each purchase, not from when you started.
If you run a monthly SIP, each instalment is a separate purchase with its own three-year clock. The instalment you paid in April becomes redeemable three years later in April; May's in May. You cannot redeem the whole holding three years after starting — the final instalment is still locked for almost three more years.
A lumpsum has one clock and becomes fully redeemable on one date. If you expect to need the money at a specific point, that difference matters.
How to use this calculator
- Choose SIP for monthly instalments or Lumpsum for a one-time investment.
- Enter the amount. Remember that only ₹1.5 lakh a year attracts the 80C deduction, across all 80C instruments combined — EPF, life insurance premiums, principal on a home loan and the rest all share that limit.
- Set an expected return rate. ELSS is equity, so model it like equity; 10–12% is a common long-run assumption.
- Set the time period. Three years is the minimum, but ELSS is an equity fund and three years is a short horizon for one. Most investors should be modelling considerably longer.
The tax position, start to finish
Going in. Up to ₹1.5 lakh a year is deductible under 80C in the old regime. At the 30% slab that is up to ₹46,800 of tax saved including cess — a real return on day one, but only once, and only on the first ₹1.5 lakh.
While invested. Nothing is taxed. There is no annual charge on the growth.
Coming out. Because the lock-in is three years, every redemption is long-term by definition. Long-term capital gains on equity above ₹1.25 lakh in a financial year are taxable at 12.5%. The calculator's output is before this.
So the complete picture is: a deduction going in, tax-free growth throughout, and capital gains tax on the way out above the annual exemption.
Things worth weighing
- It is equity. The 80C label does not reduce the volatility. A three-year horizon in an equity fund can easily end below where it started.
- The lock-in cuts both ways. It prevents panic selling, which helps most investors. It also means you cannot exit a fund that is underperforming.
- Don't let the tax break choose the fund. Among ELSS funds, the deduction is identical. The only thing separating them is the portfolio, the manager and the expense ratio.
