Money & Trade — Mutual Fund Planning

SIP Calculator, see how small monthly investments grow.

Set a monthly amount, an expected return, and a tenure, and watch compounding turn steady contributions into a future corpus — the same math used to plan retirement, a house, or a child’s education.

Formula

Future value equals P × [((1 + r)^n − 1) ÷ r] × (1 + r), where P is the monthly amount, r is the monthly rate, and n is the number of months invested.

Rupee cost averaging

Investing the same amount every month buys more units when prices dip and fewer when they rise, smoothing out the average cost over time.

Before you commit

This is an estimate based on the return you enter, not a guarantee. Real mutual fund performance moves with the market.

Mutual fund investments are subject to market risk. This tool gives an illustrative estimate only and is not investment advice — read scheme documents carefully and consult a financial advisor before investing.

About

What a SIP calculator actually shows you

Investing regularly is one of the most effective ways to build long term wealth. A SIP calculator estimates how a fixed monthly mutual fund contribution might grow, so you can plan with numbers instead of guesswork.

What is a Systematic Investment Plan

A Systematic Investment Plan lets you invest a fixed amount in a mutual fund at regular intervals, usually monthly, instead of putting in one large lump sum. It builds a habit of disciplined investing and lets you benefit from compounding and rupee cost averaging over time.

By entering a monthly amount, an expected rate of return, and a tenure, the calculator estimates your total investment and the returns it could generate.

Why use one before you invest

  • Estimate future wealth — see roughly how much a consistent monthly habit could accumulate.
  • Plan financial goals — retirement, a house down payment, or education funding become concrete numbers.
  • Stay motivated — watching a projected corpus grow keeps monthly contributions consistent.
  • Skip the manual math — compound interest by hand is fiddly; the calculator does it instantly.

Worked example

$500/month at 12% annually for 20 years → invested $120,000 → future value around $499,000

The gap between what was invested and the final value is almost entirely compounding at work — the longer the tenure, the larger that gap tends to get.

Factors that move the outcome

Duration

Longer tenures give compounding more time to work, generally raising the potential outcome.

Expected return

Mutual funds don’t offer fixed returns — the rate you enter is only an estimate based on historical performance.

Monthly amount

A higher monthly contribution scales the future value roughly in proportion.

Market conditions

Equity funds can fluctuate in the short run but often aim for higher long term growth than traditional savings.

For background on how SIPs work in practice, see the Association of Mutual Funds in India’s overview of Systematic Investment Plans.

FAQs

Common questions

Are SIP returns guaranteed?+
No. SIP returns are market-linked, so the figure this calculator shows is an estimate based on the return rate you enter, not a promised outcome. Actual performance depends on the underlying mutual fund and broader market conditions.
What return rate should I use?+
A rate between 10% and 12% is commonly used for long term equity mutual fund projections, though this varies by fund category — debt funds, for instance, tend to run lower. Treat whatever rate you enter as a planning assumption, not a forecast.
How long should I stay invested for a SIP to be worthwhile?+
A tenure of five years or more is generally suggested so compounding has room to work. Shorter SIPs can still make sense for specific near term goals, but the long term wealth effect is strongest over longer horizons.
Can I pause, stop, or change my SIP amount later?+
Yes. Most SIPs can be increased, decreased, paused, or stopped at any time without a penalty, which is part of what makes them a flexible way to invest compared to a one-time lump sum.
What happens if I miss a monthly installment?+
Missing a single installment usually doesn’t carry a penalty, but repeatedly missing payments can lead the fund house to cancel the SIP mandate, so it’s worth staying on top of it if your circumstances change.
Are SIP investments taxed?+
The SIP contributions themselves aren’t taxed going in, but gains earned when you eventually redeem your units may be subject to capital gains tax, depending on the fund type and how long you held it.
