How to use this calculator
- 1
Choose SIP for a fixed monthly amount or lumpsum for one investment made today.
- 2
Enter the amount, a tenure of at least 3 years (shorter entries are raised to 3, except 0, which falls back to 5) and an assumed annual return. The return is a figure you supply, not a forecast.
- 3
Pick 5%, 20% or 30% as the rate used for the Section 80C line. That line is an old-regime illustration only.
- 4
Read the maturity value, the LTCG line, the post-tax maturity and the 80C lines. All of them rest on one constant return every year.
Frequently asked questions
How does this tool compute the maturity value?
For a SIP it divides the annual return by 12, treats every instalment as paid at the start of its month, and sums the compounded instalments over tenure × 12 months. For a lumpsum it compounds once a year: amount × (1 + return)^years. Both assume the same return in every year, so it is an arithmetic illustration and not a projection of any fund.
How is the LTCG line worked out?
The tool subtracts a flat ₹1,25,000 exemption from the total gain, applies 12.5% to the remainder and adds 4% cess. These are the Section 112A figures built into this tool for listed equity and equity-oriented funds (transfers on or after 23 July 2024), and they are applied once to the whole gain as if everything were redeemed on the last day. Rules change in most Union Budgets and the tool is not updated automatically, so confirm the current rate and exemption with the Income Tax Department or a chartered accountant.
How is the 80C tax saving calculated?
The yearly amount invested (SIP amount × 12, or the lumpsum) is capped at ₹1,50,000, multiplied by the bracket you pick (5%, 20% or 30%) and then by 1.04 for cess. For a SIP the yearly saving is repeated for every year of the tenure; for a lumpsum it is counted once, because the money goes in once.
Does the 80C line apply under the new tax regime?
The tool does not check your regime. The 80C line is an old-regime illustration, and it assumes none of your ₹1,50,000 limit is already used by EPF, a home-loan principal repayment, life insurance or other items. If part of the limit is used elsewhere, the saving shown here is overstated.
What does the 3-year lock-in mean in the results?
The tool prints “3 years per SIP instalment” and raises a tenure of 1 or 2 years to 3. A tenure of 0, which is also what a cleared box becomes, falls back to 5 years. It does not model each instalment becoming redeemable on its own date; the whole maturity value is shown at the end of the tenure.
What happens with a zero return?
A return of 0, which is also what a cleared box becomes, is respected: a SIP of ₹5,000 a month for 3 years at 0% returns ₹1,80,000 with no gain and no tax line, and a lumpsum of ₹50,000 returns ₹50,000.
What costs and risks are left out?
Expense ratio, exit load, market falls, dividends, stamp duty, inflation, surcharge on high incomes and the possibility of staggered redemptions are not modelled. The only inputs are amount, tenure, return and bracket, so the output cannot show how a real fund behaved.
ELSS return and Section 80C arithmetic: how each line is built
How the maturity value is built
The tool takes the amount, the tenure and one assumed annual return, then compounds. A SIP uses a monthly rate equal to one twelfth of the annual figure, with each instalment paid at the start of the month; a lumpsum compounds once a year. Total invested, gain and post-tax maturity follow from that single maturity number. Because the return is the same every year, the result is a clean illustration of compounding, not a view on what any equity fund will deliver. Indian tax rules and limits change in nearly every Union Budget, and the tool’s tables are not updated automatically, so the Income Tax Department or a qualified chartered accountant governs the final tax position.
Two worked examples from the tool
A SIP of ₹5,000 a month for 5 years at an assumed 12% invests ₹3,00,000 and matures at ₹4,12,432, a gain of ₹1,12,432. That is below the built-in ₹1,25,000 exemption, so the LTCG line is ₹0 and the post-tax maturity equals the maturity value, ₹4,12,432. Doubling the instalment to ₹10,000 for 10 years at 12% invests ₹12,00,000 and reaches ₹23,23,391; the gain is ₹11,23,391, the LTCG line grows to ₹1,29,791 and post-tax maturity is ₹21,93,600. The longer tenure, not only the larger instalment, is what pushes the gain far past the exemption.
Four runs side by side
The table below lists the four fixed-input runs used on this page, including a lumpsum and a zero-return case. The last column shows how the 80C line treats a SIP versus a lumpsum: the ₹1,20,000 a year invested through the ₹10,000 SIP produces ₹37,440 a year at 30% with cess, while the ₹1,50,000 lumpsum produces its ₹31,200 at 20% only once.
| Inputs | Maturity value | Invested | LTCG line | Post-tax maturity | 80C saving |
|---|---|---|---|---|---|
| SIP ₹5,000, 5 years, 12%, 30% | ₹4,12,432 | ₹3,00,000 | ₹0 | ₹4,12,432 | ₹18,720 a year, ₹93,600 total |
| SIP ₹10,000, 10 years, 12%, 30% | ₹23,23,391 | ₹12,00,000 | ₹1,29,791 | ₹21,93,600 | ₹37,440 a year, ₹3,74,400 total |
| Lumpsum ₹1,50,000, 7 years, 10%, 20% | ₹2,92,308 | ₹1,50,000 | ₹2,250 | ₹2,90,058 | ₹31,200 once |
| Lumpsum ₹50,000, 3 years, 0%, 5% | ₹50,000 | ₹50,000 | ₹0 | ₹50,000 | ₹2,600 once |
How much the assumed return matters
Holding the SIP at ₹5,000 a month for 5 years and changing only the return shows the spread. At 6% the maturity value is ₹3,50,594, at 9% it is ₹3,79,949, at 12% it is ₹4,12,432 and at 15% it is ₹4,48,408. The post-tax figure is identical to the maturity value at 6%, 9% and 12% because the gain stays under the ₹1,25,000 exemption built into the tool, but at 15% the LTCG line takes ₹3,043 of the result, leaving ₹4,45,365. Use this to see how sensitive a plan is to the return you type in rather than to pick one.
What the tax lines assume and leave out
The LTCG line uses the Section 112A figures built into this tool, a 12.5% rate with a ₹1,25,000 exemption (transfers on or after 23 July 2024) and 4% cess, applied once to the entire gain. The 80C line caps the yearly investment at ₹1,50,000 and assumes the limit is otherwise unused and that you are in the old regime. Expense ratios, exit loads, surcharge, market falls and staggered redemptions are not modelled. Treat the output as arithmetic for comparing amounts and tenures, and confirm current rates and limits with the Income Tax Department or a chartered accountant.
