What a SIP calculator actually tells you

A Systematic Investment Plan is an instruction to invest a fixed amount every month into a mutual fund. A SIP calculator answers one question about it: if you keep that up for a set number of years and the fund averages a given return, what is the pot worth at the end?

The part people miss is that the answer is dominated by time, not by the amount. Doubling your monthly instalment doubles the result. Doubling the number of years does much more than double it, because every early instalment earns returns for longer, and those returns then earn returns of their own.

How the calculation works

Each instalment is compounded for however many months it has left to run. Rather than adding up hundreds of separate terms, the standard formula collapses them into one:

FV = P × ([(1 + i)^n − 1] ÷ i) × (1 + i)
  • FV is the value at the end
  • P is your monthly instalment
  • i is the monthly return, so a 12% annual rate is 0.12 ÷ 12 = 0.01
  • n is the number of instalments, so 10 years is 120

The trailing (1 + i) is there because a SIP mandate debits at the start of the month, so every instalment earns one extra month of return.

A worked example

Invest ₹10,000 a month for 10 years at 12% a year. You put in ₹12,00,000 across 120 instalments. The projection comes to about ₹23,23,391, so roughly ₹11.2 lakh of it is return rather than your own money. Extend the same SIP to 20 years and you invest ₹24,00,000, but the projection reaches about ₹99.9 lakh. You doubled the years and the returns grew more than fourfold.

What common SIP amounts grow to

The same arithmetic, run across the amounts and horizons people usually ask about, at 12% a year. Read down a column to see what an extra ₹1,000 a month is worth, and across a row to see what an extra five years is worth. The second effect is much larger than the first.

A ₹5,000 SIP held for 25 years and a ₹25,000 SIP held for five both put in exactly ₹15 lakh. The first ends near ₹95 lakh and the second near ₹21 lakh. Same money, four and a half times the result, and the only difference is when it started.

Why this calculator shows a range

Every SIP calculator you will find returns one number. That number assumes the fund delivers exactly the same return every single year, which no fund has ever done. Presenting it alone turns an assumption into what looks like a promise.

The range above is a one-standard-deviation band around the same projection, using the historical volatility of Indian equity. Roughly two periods in three land inside it. It also narrows as the horizon lengthens, which is the strongest argument for long holding periods that exists: a longer SIP is not just bigger, it is more predictable.

How to use this calculator

  1. Set the monthly amount you can genuinely sustain. A SIP you stop after eight months is worse than a smaller one you keep for eight years.
  2. Set a realistic return. 11–13% for equity funds, 6–8% for debt.
  3. Set the number of years you will leave it alone.
  4. Add a step-up if your income rises. Even 5% a year changes the outcome substantially.
  5. Toggle In today's money to see what the result buys at present-day prices, and After tax to see what you keep.

What the calculator cannot tell you

It cannot tell you which fund to buy, and that is the decision that determines whether you get anywhere near the rate you typed. Two equity funds in the same category can differ by several percentage points a year over a decade. The projection is arithmetic; the return is a research problem.

That is what a model portfolio is for: a published set of holdings and weights from a SEBI-registered desk, with a written reason behind every change, so you are not picking funds by last year's league table.

Frequently asked questions

What is a SIP calculator?

A SIP calculator estimates what a monthly investment could grow into. You enter the amount you plan to invest each month, the return you expect per year and how long you will keep going, and it compounds those instalments to give a projected value at the end.

How accurate is a SIP calculator?

The arithmetic is exact, but the answer is only as good as the return you assume. A calculator applies the same rate every year, and markets do not work that way. A fund averaging 12% might return 30% one year and fall 15% the next. Treat the result as the middle of a range, not a forecast. That is why this calculator also shows the range around the answer.

What return rate should I use for a SIP calculator?

For Indian equity mutual funds, 11% to 13% a year is a reasonable long-run assumption. Debt funds are usually modelled at 6% to 8%. Using 15% or more will produce a number that looks excellent and is unlikely to happen. If you are unsure, run the calculator twice, at 10% and at 13%, and plan against the lower one.

What is a step-up SIP and should I use one?

A step-up SIP increases your monthly instalment by a fixed percentage each year, usually in line with your salary. It matters more than most people expect: a 10% annual step-up on a ₹10,000 SIP over 20 years roughly doubles the final corpus compared with keeping the instalment flat, because the later, larger instalments still get years of compounding.

Does a SIP calculator account for inflation?

Most do not, which is why their answers feel larger than they are. ₹1 crore in 25 years buys roughly what ₹23 lakh buys today at 6% inflation. Use the 'In today's money' toggle above to convert the projection into present-day purchasing power before you decide whether the number is enough.

Do I pay tax on SIP returns?

Yes. Gains on equity mutual fund units held longer than a year are long-term capital gains, taxed at 12.5% on the amount above the annual exemption of ₹1.25 lakh. Units held for a year or less are taxed at 20%. Because each SIP instalment buys units on a different date, each has its own holding period. The 'After tax' toggle shows an illustrative post-tax figure.

Is a SIP better than a lumpsum investment?

Neither is universally better. A SIP spreads your entry across many prices, which removes the risk of committing everything at a peak and makes it easier to keep investing through a fall. A lumpsum puts the whole amount to work immediately, which wins when markets rise steadily from the day you invest. If the money already exists, a lumpsum has historically won more often; if it arrives monthly from a salary, a SIP is the only option that fits.

How much will a ₹5,000 monthly SIP be worth in 10 years?

At 12% a year, a ₹5,000 SIP run for 10 years projects to about ₹11.6 lakh, of which ₹6 lakh is your own money. Over 20 years the same instalment projects to roughly ₹50 lakh, and over 25 years to about ₹95 lakh. The table above covers the other common combinations.

How much do I need to invest monthly to reach ₹1 crore?

It depends almost entirely on how long you have. At 12% a year you need roughly ₹43,000 a month to get there in 10 years, about ₹20,000 a month over 15 years, and about ₹10,000 a month over 20 years. Switch this calculator to goal mode and enter your target to see the exact figure for your horizon.

What is the minimum amount for a SIP?

Most fund houses accept ₹500 a month, and several allow ₹100. The minimum is rarely the constraint that matters. What matters is picking an instalment you can keep paying through a bad year, because stopping during a fall is what actually damages long-run returns.

Can I stop or change a SIP?

Yes. A SIP is an instruction, not a lock-in. You can pause it, change the amount or stop it entirely without penalty, and the units you already hold stay invested. Tax-saving ELSS funds are the exception: each instalment is locked for three years from its own purchase date.
