Enter a monthly investment, expected return, and duration to project your systematic investment plan's maturity value — with optional annual step-up and inflation-adjusted real value.
Cumulative invested amount vs. projected value, year by year.

SIP uses the future value of an annuity formula: each monthly investment compounds at the monthly rate for the remaining months, and all installments are summed — maturity = P × [(1+r)^n − 1] / r × (1+r), where P is your monthly amount, r the monthly rate, and n the number of months. Returns are estimates, not guarantees.
A step-up SIP increases your monthly contribution by a fixed percentage every 12 months — matching how most people's investable income actually grows. A 10% step-up on a ₹10,000/month SIP means ₹11,000/month in year two, ₹12,100/month in year three, and so on. Because later, larger contributions still get meaningful time to compound, a step-up SIP produces a noticeably larger maturity value than a flat SIP with the same starting amount.
Maturity value is the nominal future amount; real value discounts that by your expected inflation rate to show what it's actually worth in today's purchasing power: real value = maturity ÷ (1 + inflation%)^years. A large maturity number can still lose to inflation if the assumed return barely beats it.
12% is a commonly used illustrative assumption for equity mutual funds in India based on long-term historical averages, but actual returns vary year to year and aren't guaranteed. Consider also running the numbers at a more conservative rate (e.g. 8–10%) as a stress test.
Worked example: investing ₹10,000/month for 10 years at an assumed 12% annual return grows to roughly ₹23.2 lakh, of which ₹12 lakh is your own contribution and about ₹11.2 lakh is projected growth.
