SIP Calculator

Calculate the estimated future value of monthly SIP investments based on your contribution, expected return, and investment duration.

Calculate SIP value
Enter a monthly contribution and an assumed return to estimate a future value.

Your SIP estimate will appear here

Enter the contribution, expected return, and duration, then select Calculate SIP.

SIP future-value formula

The annual return is divided by 12 and 100 to obtain a monthly decimal rate. This formula assumes each contribution is made at the beginning of the month, so every instalment receives one additional month of potential growth.

FV = P × [((1 + r)ⁿ − 1) ÷ r] × (1 + r)

P
Monthly SIP contribution
r
Expected monthly rate of return as a decimal
n
Total number of monthly contributions

SIP calculation example

For a ₹10,000 monthly SIP with an assumed 12% annual return over 10 years, the calculator uses 120 beginning-of-month contributions. Actual mutual fund returns will vary.

Sample inputs

Monthly investment
₹10,000
Expected annual return
12%
Investment duration
10 years

Example results

Estimated future value
₹23,23,390.76
Total invested
₹12,00,000.00
Estimated returns
₹11,23,390.76
Monthly investments
120

How to use the SIP calculator

  1. Enter the planned monthly contribution.
  2. Enter an expected annual return as an assumption, not a promise.
  3. Choose the duration and compare invested amount with estimated value.

How contribution, return, and duration affect results

Higher contributions increase the amount invested. A higher assumed return or longer duration raises the projection, but actual market outcomes may differ materially.

Compounding over longer durations

Projected returns can themselves generate later returns. Time therefore has a nonlinear effect, although market returns do not arrive smoothly or at a guaranteed rate.

Invested amount versus estimated returns

Invested amount is the sum of contributions. Estimated returns are the projected value minus those contributions and can be negative in real investments.

Beginning-of-month contribution assumption

Benefits of disciplined investing

  • Creates a regular contribution habit.
  • Spreads contributions across different market dates.
  • Makes progress easier to review against a long-term plan.

Limitations and assumptions

The projection uses a constant assumed return. It does not model volatility, inflation, taxes, fees, missed contributions, or product-specific rules unless explicitly stated.

Common SIP calculation mistakes

  • Treating the assumed return as guaranteed.
  • Ignoring fees, taxes, inflation, or volatility.
  • Confusing annual and monthly return rates.
  • Assuming contributions always occur on the modeled date.

Practical tips

  • Test a range of return assumptions.
  • Review invested amount separately from projected gains.
  • Use a duration that reflects the decision being explored.
  • Revisit assumptions when circumstances change.

Frequently asked questions

What is a SIP?

A Systematic Investment Plan, or SIP, is a way to invest a fixed amount in a mutual fund at regular intervals, commonly each month.

How is SIP maturity value calculated?

The estimate compounds each monthly contribution for its remaining investment period. This calculator assumes contributions are made at the beginning of each month.

Are SIP returns guaranteed?

No. Mutual fund returns depend on market performance and can differ significantly from the rate entered. The result is an estimate, not a guaranteed outcome.

What return rate should I enter?

Use a reasonable assumption suited to the investment being evaluated or review long-term historical information. Past performance does not guarantee future returns.

Can I stop or change my SIP?

Many SIPs allow investors to pause, stop, increase, or decrease contributions, subject to the fund and platform terms. Check the applicable scheme documents.

Does this calculator include taxes, fees, or inflation?

No. The estimate does not account for expense ratios, taxes, exit loads, transaction costs, or inflation, all of which may affect real-world outcomes.
