How the Goal-Based SIP Calculator Works

This calculator flips the usual SIP question around: instead of asking 'what will my monthly investment grow to', it asks 'how much do I need to invest monthly to reach a specific target'. Set your goal amount, how many years you have, and an expected annual return, and it works backward using the inverse of the standard SIP future-value formula to tell you the required monthly contribution.

This is the calculation most useful for goal planning -- a child's education fund, a house down payment, a retirement corpus -- where the target amount and timeline are fixed and the open question is simply how much you need to set aside each month. As with the regular SIP calculator, the result depends entirely on the return rate you assume actually holding up over the full period, so it's worth revisiting the number periodically as real returns come in.

Required Monthly SIP = M × i / [((1 + i)^n − 1) × (1 + i)], where M = target corpus, i = annual return ÷ 12 ÷ 100, n = years × 12

Worked example (the calculator's own defaults)

To reach a ₹50,00,000 goal in 20 years at an assumed 12% annual return, you'd need to invest approximately ₹5,004 a month -- a total of roughly ₹12,01,023 out of pocket over 20 years, with the remaining ₹37,98,977 coming from compounding.

Frequently asked questions

What happens if I can't afford the required monthly amount?

You have three levers to adjust: extend the timeline, lower the target amount, or increase the assumed return by choosing a higher-growth (and higher-risk) asset allocation. Try adjusting each one to see which combination fits your actual budget.

Should I use a conservative or optimistic return assumption for a fixed goal?

Conservative is safer for a goal you can't miss (education, a wedding, retirement) -- an optimistic assumption that doesn't pan out means falling short right when you need the money. Many planners use a lower assumed return for near-term or non-negotiable goals.

Does this account for inflation eating into my goal amount?

No -- the target amount you enter is treated as a fixed rupee figure. If your goal is years away, consider entering an inflation-adjusted target (today's cost inflated forward) rather than today's cost, so the corpus is actually enough when you need it.
