These are projections, not promises
The figures assume a steady return every year. Real markets do not behave that way — they deliver the average through a mix of strong years and sharply negative ones, and the order those arrive in matters. Figures are also before tax and before inflation. Try a rate three or four points lower and see whether the plan still works.
How SIP returns are calculated
Each instalment is invested at a different time, so each one compounds for a different length of time. The first instalment in a ten-year SIP grows for ten years; the last one grows for a month. The total is the sum of all of them.
FV = P × ((1 + i)^n − 1) / i × (1 + i)
P = monthly investment
i = annual rate / 12 / 100 (monthly rate)
n = number of months
The trailing (1 + i) is the part most explanations skip. It is there because a SIP instalment is debited at the start of the month, so every contribution earns one extra month of growth compared with the standard end-of-period formula. Leaving it out understates a twenty-year SIP noticeably, and would put these figures out of step with every other Indian calculator.
Why the later years do the work
In the early years, most of your balance is money you put in. The crossover — where accumulated returns exceed total contributions — typically arrives somewhere around year eight to ten at a 12 per cent assumption. After that, growth increasingly comes from returns on previous returns rather than from new instalments, which is why stopping early costs far more than the contributions you skip.
Frequently asked questions
What return rate should I assume?
Nobody knows what a fund will return, which is why this is an assumption rather than a projection. Indian equity indices have historically averaged somewhere around 11 to 13 per cent a year over long periods, debt funds considerably less. Whatever you pick, run the numbers again at a rate three or four points lower to see how the plan holds up, because the average conceals years that are sharply negative.
Does this account for inflation?
No. The figures are nominal, meaning they are in future rupees rather than in what those rupees will buy. At 6 per cent inflation, money roughly halves in purchasing power over twelve years, so a maturity value of one crore in twenty years is not one crore in today’s terms. A rough way to see the real value is to subtract expected inflation from your return rate.
What is a step-up SIP?
A SIP where you increase the monthly amount by a set percentage every year, usually in line with a salary rise. It makes a substantial difference over long periods, because the larger contributions still get years of compounding. A 10 per cent annual step-up on a twenty-year SIP typically ends well above a flat one.
Are returns from a SIP taxed?
Yes, and this calculator does not model that. Equity mutual fund gains are subject to capital gains tax, with the rate depending on how long each instalment was held. Because every SIP instalment has its own holding period, the tax treatment is genuinely fiddly. Treat the figures here as pre-tax, and check the current rules for your situation.
Why does the calculator assume investment at the start of the month?
Because that is when a SIP instalment is actually debited, and it is the convention every major Indian calculator uses. Assuming the end of the month would understate the result by roughly one month of growth, which over twenty years is a visible difference.
