Goal SIP calculator
To reach ₹1 crore in 15 years at 12% a year you need about ₹19,819 a month. This calculator runs the SIP formula backwards for any target, and — the part most tools skip — re-prices your goal for inflation first, so you are aiming at what the thing will actually cost.
What you want, and when
Priced in today’s money. The inflation field converts it to what you will actually need.
An assumption, not a promise. Equity funds are usually modelled at 10–12%; see what rate to assume.
Set 0 to switch the "today’s money" column off. India’s CPI has averaged close to 6% over the past decade; the RBI targets 4% with a 2-point band.

Running the formula backwards
The forward SIP formula turns an instalment into a corpus. Rearranged, it turns a corpus into the instalment required:
P = FV ÷ ( [ ((1 + r)n − 1) ÷ r ] × (1 + r) )
This is an exact inverse, not an approximation — feed the answer back into the forward calculator and you land on your target to the rupee.
Three levers move the answer: the amount, the time, and the return. Time is by far the most powerful, and the only one fully under your control. Stretching a 10-year goal to 15 cuts the required monthly SIP by roughly 45% at 12% — a far bigger effect than any plausible change in return assumption.
Why the goal has to be re-priced first
"I need ₹1 crore in 15 years" almost always means "I need what ₹1 crore buys today". Those are different numbers. At 6% inflation, matching today's ₹1 crore of purchasing power in 15 years takes about ₹2.4 Cr.
Plan to the raw ₹1 crore and you will hit your number and miss your goal by roughly 58%. This is the most common and most expensive goal-planning mistake, and it is entirely avoidable.
So the calculator inflates the target first, then solves. If you would rather aim at the literal figure, set inflation to 0 — but do that deliberately, not by accident.
When the number comes back impossible
Frequently it will, and that is useful information rather than a failure. Four responses, in descending order of how well they usually work:
- Give it more time. The strongest lever by a wide margin, and it costs nothing but patience.
- Step it up instead of starting big. You may not afford the flat figure today but might afford a rising one. Check the step-up calculator.
- Shrink the goal. Unglamorous, frequently correct.
- Raise the return assumption. Listed last on purpose. Changing the number in a spreadsheet does not change what markets deliver, and a plan that only works at 15% is a plan that depends on luck.
Before you rely on this
An estimate, not a forecast
This is arithmetic applied to assumptions you chose. Mutual funds carry market risk, returns are not guaranteed, and past performance does not indicate future results. Nothing here is personalised advice — for decisions of any size, speak to a SEBI-registered investment adviser.
Questions people actually ask
How much SIP do I need for ₹1 crore?
At 12% a year: roughly ₹43,041 a month over 10 years, ₹19,819 over 15, and ₹10,009 over 20. The same target, and the monthly figure falls by about 77% simply by allowing twice as long.
Those figures aim at a literal ₹1 crore. For ₹1 crore of today's purchasing power, see the crorepati calculator.
Should I use one SIP for several goals or one per goal?
One per goal, if the goals have different deadlines — which they almost always do. A three-year car and a twenty-year retirement need different funds, because a twenty-year horizon can absorb equity volatility and a three-year one cannot.
Separate SIPs also make it obvious what you are raiding when you decide to raid something, which is a real behavioural benefit.
What return rate should I assume for a short goal?
Much lower than for a long one, because a short horizon cannot ride out a bad year. For anything inside three years, equity assumptions are inappropriate — a 12% projection on a two-year goal is not optimism, it is a mistake.
Debt funds or deposits at 6–7% are the honest assumption there. See the return rate guide.
Can I reach the goal with a one-time investment instead?
The calculator shows that figure too — the "or invest once, today" row is the present value of your target at the same return rate. It is normally much smaller than the SIP total, for the usual reason: it compounds for the whole period.
