Find the monthly SIP needed to reach a future target after inflating today’s cost and earning a steady return on investments.
Explore tools that pair well with this one—loans, investing, and planning.
This calculator answers: “If my goal costs this much today and will cost more by the goal date, what fixed monthly SIP do I need?” It inflates today’s goal by your goal inflation rate to get the nominal corpus required, then solves for the monthly investment that reaches that corpus given your expected return — same monthly pattern as the standard SIP calculator.
Future corpus = today’s goal × (1 + goal inflation)^years. Monthly SIP = future corpus ÷ [((1 + monthly return)^months − 1) / monthly return], with monthly return = annual investment return ÷ 12.
Enter today’s goal cost, years until you need the money, annual inflation on that goal, and expected annual return on the SIP. Review the monthly SIP required, the inflated future cost, and how much of the total comes from your contributions versus growth.
The price or amount in today’s rupees — for example what the house or education costs now. The calculator inflates that by your goal inflation rate to estimate the nominal amount you will need at the goal date.
Goal inflation models how the thing you are saving for may get more expensive. Investment return is what you assume your mutual fund or portfolio earns. They are separate: property might rise at 6% while your equity SIP might average 12%.
No — it solves for a constant monthly SIP, matching the base SIP calculator without step-up. If you increase SIP every year, you would need less initially than shown.
It uses the standard future value of a monthly annuity with the same timing as the main SIP calculator (contribution after each month’s return). Rounding in display may differ slightly from your fund’s actual cut-off dates.
You can use it for any single lump-sum goal at a future date. For ongoing retirement spending, the retirement or SWP calculators are usually more appropriate.
Use these notes to stress-test the calculator, understand what drives the result, and choose the right tool for the decision you are making.
The tool works backward from one future lump-sum target and assumes a constant monthly SIP, a constant annual return, and a constant inflation rate for the goal itself. It does not model annual step-up, irregular contributions, or multiple goal dates.
Suppose a goal costs 20 lakh today, is 10 years away, and rises 6% annually. The calculator first inflates that cost to a future target, then computes the monthly SIP required to reach it at your expected investment return. If your return assumption falls, the required SIP rises quickly.
The suggested SIP is best read as a planning minimum under your assumptions. If the computed number already feels aggressive for your monthly budget, that is often a signal to either extend the timeline, lower the goal, or plan for periodic top-ups.
Use this tool when you want a monthly SIP answer for a future lump-sum goal. Use the Savings Goal calculator when you want to compare monthly versus yearly contribution patterns and include an existing starting balance more explicitly.
