SIP Calculator

Project the maturity value of a Systematic Investment Plan, with optional annual step-up.

Please note: Mutual fund investments are subject to market risk. Returns shown are assumptions, not guarantees.

What the SIP Calculator does

A SIP invests a fixed amount every month, which averages your purchase price across market highs and lows. The step-up option raises your instalment each year, which typically lifts the final corpus dramatically as your income grows.

Formula

FV = PMT × ((1 + i)ⁿ − 1) ÷ i, where i = annual return ÷ 12
With step-up, the instalment is multiplied by (1 + step) at each anniversary

Worked example

₹10,000 a month for 15 years at an assumed 12%, with a 10% annual step-up.

Monthly: 10000
Rate: 12
Years: 15
Step-up: 10

₹3,812,697.80 invested across 180 instalments grows to ₹8,597,870.72 — returns of ₹4,785,172.92, a 2.26× multiple.

Reading the result

The maturity value splits into what you contributed and what the returns added. Early in a plan the contributions dominate; the crossover typically arrives after a decade or more.
A step-up materially changes the outcome because each increase compounds for the remaining years, not just the year it is applied.
SIP returns are usually quoted as XIRR rather than a simple percentage, because each instalment is invested for a different length of time.

Assumptions and limitations

A constant annual return, compounded monthly. Equity markets do not deliver constant returns, and the order in which good and bad years arrive changes the final figure.
Every instalment is assumed to be paid on time for the full period, with nothing withdrawn.
Exit load, expense ratio and capital gains tax are not deducted, so the real amount received is lower.

Common mistakes

Entering the expected return as a monthly rate when the field expects an annual one.
Reading the projection as a guarantee. It shows the arithmetic of a chosen rate, not the behaviour of a market.
Stopping contributions during a downturn, which removes exactly the instalments that buy the most units.

Frequently asked questions

What is a step-up SIP?

You raise the monthly amount by a set percentage each year, usually in line with salary growth. It has an outsized effect because the extra money still gets years of compounding.

Is a SIP safer than a lump sum?

It spreads timing risk rather than removing market risk. In a steadily rising market a lump sum usually wins; in a volatile one a SIP smooths the entry price.
