Frequently asked questions
How is the SIP future value calculated?
Each monthly instalment grows at the monthly rate (annual return ÷ 12) until the end of the period: FV = P × [(1 + i)^n − 1] / i × (1 + i). With a step-up the instalment rises once a year by the chosen percentage.
What return should I assume?
Past returns of equity funds do not guarantee future returns. Many planners use 10% to 12% a year for equity and lower values for debt funds; try several values to see the range.
Why look at the inflation-adjusted value?
Prices rise over time, so a future amount buys less than the same amount today. Dividing by (1 + inflation)^years shows the value in today's money.

How the SIP calculator works
This calculator is for mutual-fund investors in India who invest through a systematic investment plan (SIP) every month. In the first mode you enter the monthly amount, the expected annual return and the number of years, and it shows the estimated value at the end, the total invested and the estimated returns. In the second mode you enter a target amount and it shows the monthly SIP needed to reach it. You can also add an annual step-up that raises the instalment once a year, a one-time lump sum invested today, and an expected inflation rate to see the result in today's money. A year-by-year table, a chart and an indicative capital-gains tax figure complete the result.
The annual return is divided by 12 to get the monthly rate. Each instalment is invested at the start of its month and grows until the end of the period; with a step-up the instalment rises once a year by the chosen percentage. The lump sum compounds monthly at the same rate, so both parts follow one convention. In goal mode the remaining target, after the lump sum, is divided by the growth factor of one rupee of SIP. The inflation-adjusted value divides the final amount by (1 + inflation)^years. For the tax note, equity gains above ₹1.25 lakh a year are taxed at 12.5% (section 198 of the Income-tax Act, 2025, old section 112A) and short-term gains at 20% (section 196, old section 111A), plus 4% cess.
Example: a SIP of ₹10,000 a month at 12% a year for 10 years has invested ₹ 12,00,000.00 and grows to about ₹ 23,23,390.76, which is 23.23 lakh. With 6% inflation that is worth ₹ 12,97,369.27 in today's money. The tax figure assumes that all units are redeemed at the end in one financial year: gains on the last 12 instalments are short-term and taxed at 20%, the rest are long-term and taxed at 12.5% above ₹1.25 lakh; surcharge and grandfathering are ignored. Real returns vary with the market, and exit loads and expense ratios are not modelled, so use the result as a planning guide and not as a promise.
