SIP Calculator: Mutual Fund SIP Returns & Maturity Value

Your browser is preparing the tool. It runs 100% locally.

Quick answer

Enter a monthly amount, an expected annual return and a number of years, and it estimates the future value, total invested and likely gains of a Systematic Investment Plan. ₹5,000 a month at 12% for 10 years projects to about ₹11.6 lakh on ₹6 lakh invested. It uses the annuity-due formula, which assumes each contribution goes in at the start of the month, and recalculates in your browser as you type.

What the SIP Calculator does

Put in a monthly investment, an expected annual return and a number of years, and the tool projects the future value, how much you'll have put in, and the estimated gains on top. It works in rupees and updates as you type.

A SIP means investing a fixed sum every month into a mutual fund. People like it for the discipline and for rupee-cost averaging: a fixed amount buys more units when prices dip and fewer when they rise. The calculator projects the compounded result at a steady assumed return.

How it works

It converts your inputs to a monthly rate (the annual return divided by 12) and a number of months (years times 12), then applies the future-value formula for an annuity due, which compounds each monthly contribution to the end of the term.

Total invested is the monthly amount times the number of months, and estimated returns are the projected future value minus what you put in.

Methodology

Step 1. Take the monthly amount M, the expected annual return, and the number of years.
Step 2. Convert to a monthly rate i (annual ÷ 12 ÷ 100) and months n (years × 12).
Step 3. Apply FV = M × ((1 + i) to the power n − 1) ÷ i × (1 + i).
Step 4. Compute invested = M × n, and estimated returns = FV − invested.
Step 5. Recalculate whenever an input changes.

SIP future value (annuity due)

FV = M × ((1 + i)^n − 1) ÷ i × (1 + i)
M = monthly amount, i = monthly rate (annual ÷ 12), n = months
Invested = M × n, Returns = FV − Invested

Worked examples
₹5,000/month at 12% p.a. for 10 years (i = 0.01, n = 120): FV ≈ ₹11,61,695 on ₹6,00,000 invested
The extra ≈ ₹5,61,695 is the projected growth at a steady 12%

The trailing × (1 + i) makes it an annuity due: each month's money is assumed to go in at the start of the period, which is how SIPs are usually modelled. Real returns change from year to year; this assumes a constant rate.

Assumptions

The same annual return every year. Real markets never behave this way, so read the result as a projection, not a promise.
The same contribution at the start of each month (annuity due), never missed.
Returns are reinvested and compound, with no withdrawals.
The figure is gross. It ignores the fund's expense ratio, exit loads and capital-gains tax.

Standards and references

Annuity-due future value: FV = M × ((1+i)ⁿ−1)/i × (1+i), the future value of a regular contribution made at the start of each period.
Systematic Investment Plan (SIP): a fixed amount invested in a mutual fund at regular intervals. In India it is a common way to invest steadily for the long term.
Rupee-cost averaging: investing a fixed sum each month buys more units when prices fall and fewer when they rise, which evens out the average cost.

Accuracy and limits

This is an estimate at one constant return. Real mutual-fund returns swing from year to year, so the actual outcome will differ, sometimes sharply, especially over shorter periods.

The figure is gross. It doesn't subtract the fund's expense ratio, any exit load or capital-gains tax, and each of those reduces what you actually keep.

Inflation isn't applied, so ₹11.6 lakh in ten years won't buy what ₹11.6 lakh buys today.

It assumes you never miss or change a contribution. A step-up SIP, a pause, or a market dip at the wrong moment all change the real result.

Projecting a monthly mutual-fund SIP
Planning toward a goal

Not the best choice for

A one-time lump sum
A bank recurring deposit
Guaranteed or after-tax figures

Investing a lump sum once? Use the compound interest calculator. A bank recurring deposit? Use the RD calculator. This is a gross projection, so subtract fund costs and tax for a realistic figure.

Frequently asked questions

What is a SIP?

A Systematic Investment Plan: investing a fixed amount into a mutual fund at regular intervals, usually monthly. Many Indian investors use it to build savings steadily over the long term.

What formula does it use?

The future value of an annuity due: FV = M × ((1+i) to the power n − 1) ÷ i × (1 + i), with M the monthly amount, i the monthly rate and n the number of months.

Why the extra × (1 + i)?

That makes it an annuity due, which assumes each contribution is made at the start of the month. SIPs are normally modelled this way, and it gives a slightly higher figure than end-of-month timing.

What does ₹5,000 a month at 12% for 10 years project to?

About ₹11,61,695 on ₹6,00,000 invested, so roughly ₹5,61,695 of projected growth, assuming a steady 12% a year.

Is the return guaranteed?

No. Mutual funds aren't guaranteed, and the constant return here is an assumption. The real outcome depends on the market and will vary.

Does it account for taxes and fund charges?

No, the figure is gross. A fund's expense ratio, any exit load and capital-gains tax all reduce the real return, so subtract them for a truer picture.

Is inflation included?

No. The future value is in nominal rupees, so what it can actually buy will be less than the number suggests.

What return should I assume?

Be conservative. Indian equity funds have historically returned roughly 10 to 12% over long periods, but past performance doesn't guarantee the future. Try a lower figure to stress-test your plan.

How is a SIP different from a lump sum?

A SIP invests a little each month; a lump sum goes in once. For a one-time investment, use the compound interest calculator instead.

How is it different from a recurring deposit?

An RD is a bank product with a fixed return; a SIP is a mutual-fund investment whose return follows the market. Use the RD calculator for a bank recurring deposit.

What is rupee-cost averaging?

Because you invest the same amount each month, you buy more units when prices are low and fewer when they're high, which evens out your average purchase cost over time.

What currency does it use?

Rupees, since that is how SIPs are described in India, but the formula works the same in any currency.

References

The projection uses the annuity-due formula (contributions at the start of each month) at one constant return. It is a gross figure before fund costs, tax and inflation, and real markets won't match it year to year.
