Returns are estimates based on a constant annual rate. Actual market returns vary year to year — mutual fund SIPs carry market risk.

About this tool

A SIP — Systematic Investment Plan — is investing a fixed amount into a mutual fund every month, regardless of market conditions. It's the default way millions of people invest, especially in India, because it automates discipline and averages out market timing: you buy more units when prices dip and fewer when they rise.

This calculator answers the question every SIP investor asks: if I invest this much monthly at an expected return, what will it be worth? Enter the monthly amount, expected annual return, and period; the calculator applies the standard SIP future-value formula (contributions at the start of each month, the industry convention) and splits the result into what you invested versus what compounding earned. The visual bar makes the most motivating fact of SIP investing obvious: over long periods, the gains eventually exceed the contributions.

An honest note shown on the tool itself: the calculation assumes a constant annual return, but mutual fund returns vary year to year. The customary planning assumption for equity funds is around 10–12% annually over long periods — historical, not guaranteed. Use a conservative rate for planning and treat the output as an estimate.

Frequently asked questions

How is the SIP maturity value calculated?

With the standard future-value-of-annuity-due formula: FV = P × ((1+i)^n − 1)/i × (1+i), where P is the monthly amount, i the monthly rate, and n the number of months. Contributions are assumed at the start of each month, the SIP convention.

What return rate should I assume?

For equity mutual funds, 10–12% annually is the customary long-term planning assumption; debt funds are typically assumed lower, around 6–8%. These are historical patterns, not guarantees — using a conservative figure gives more dependable plans.

Is SIP better than investing a lump sum?

They serve different situations. SIP suits monthly income and removes timing decisions by averaging purchase prices. A lump sum invested early can outperform in steadily rising markets. Many investors do both: lump sums when available, SIP for regularity.

Does this calculator account for market risk?

No calculator can — it projects a constant rate. Real returns fluctuate, sometimes sharply. SIP results over short periods can be negative; the approach is designed for long horizons where averaging has time to work.
