How this calculator works
This works backwards from the regular SIP formula — instead of telling you what a fixed monthly amount grows into, it solves for the monthly amount that grows into your target by the deadline you set, given your expected return rate.
Why time horizon changes the required amount so much
Reaching a ₹1 crore goal at an assumed 12% return needs roughly ₹43,041/month over 10 years — but only about ₹10,009/month over 20 years, a more than 4x difference for doubling the time available. Compounding does most of the work over a longer horizon, so the single biggest lever for hitting an ambitious goal is usually starting earlier, not finding a higher return rate.
Check your assumption against a conservative rate too
A higher assumed return rate lowers the required monthly SIP shown here, but returns aren't guaranteed. It's worth re-running this at a more conservative rate (say, 2-3 percentage points lower) to see how much more you'd need to invest monthly if actual returns come in below your optimistic assumption — that gives you a realistic range instead of a single number that only works if the market cooperates.
If the required amount doesn't fit your budget
You have three levers to adjust: extend the time horizon, accept a lower target amount, or look for a realistically higher return (without assuming an unrealistic rate just to make the numbers work). For a standard forward projection instead of working backward from a goal, see the SIP Calculator.
Frequently Asked Questions
How does this calculator work backward from a goal?
It rearranges the standard SIP future-value formula to solve for the required monthly instalment, given your target amount, expected annual return, and investment duration — the reverse of a normal SIP projection.
What if I can't afford the required monthly SIP?
You have three levers: increase the duration, accept a lower target amount, or look for a higher (but realistic) expected return — try adjusting each in the calculator to see which combination fits your budget.
Does inflation affect my goal amount?
This calculator doesn't automatically adjust for inflation — if your goal is a future expense (like a child's education), consider entering an inflation-adjusted target amount rather than today's cost.
Does the time horizon really change the required SIP that much?
Yes, dramatically — reaching a ₹1 crore goal at 12% needs roughly ₹43,000/month over 10 years, but only about ₹10,000/month over 20 years, a more than 4x difference for doubling the time available. Starting earlier is usually a bigger lever than chasing a higher return rate.
What return rate should I assume for the calculation?
This calculator doesn't recommend one — it's your assumption to make. Equity mutual funds have historically returned somewhere in the 10-14% range annually over long periods in India, but returns aren't guaranteed, so a conservative estimate is safer for planning a firm goal like a down payment or tuition.
