SIP Calculator
Project a SIP or lump sum, plan a goal and see the maths behind every number.
Market returns are not guaranteed. Equity and mutual fund returns vary from year to year and can be negative; this projection assumes the same return every month.

About the SIP Calculator
A SIP (systematic investment plan) invests a fixed amount every month, usually in a mutual fund. This calculator projects what your SIP could grow to at an expected annual return, shows how much of the final amount is your own money and how much is growth, and breaks it down year by year.
Switch to Lump sum to project a one-time investment, or to Goal planner to find the monthly SIP — or the one-time amount — needed to reach a target such as ₹1 crore. Add an annual step-up to raise your SIP every year, and an inflation rate to see the result in today's money. Every result comes with the formula and the numbers that produced it.
How to use it
- Choose SIP (a monthly investment), Lump sum or Goal planner.
- Enter the amount (or the target), the expected return per year and the investment period in years.
- Optionally add an annual step-up (for example 10% a year) and an inflation rate to see values in today's money.
- Read the estimated value, total invested and gains. The chart and the year-wise table show how the money grows; Download CSV saves the table.
Examples
Invested ₹12,00,000 · Estimated value ₹22,40,359 · Gains ₹10,40,359
With the nominal r ÷ 12 convention the same inputs give ₹23,23,391 — see why below.
Invested ₹19,12,491 · Estimated value ₹32,68,898
Monthly SIP needed ₹21,011 — or ₹18,26,963 invested once today
Common uses
- Checking what a monthly SIP could grow to before you start one.
- Seeing how much a yearly step-up adds to the final amount.
- Working out the SIP needed for a goal such as a child's education, a home down payment or retirement.
- Comparing a one-time investment with a SIP using the same return and period.
How the SIP value is calculated
Each instalment is assumed to be invested at the start of its month, so every instalment earns at least one month of returns. For a fixed SIP the future value is:
FV = P × [((1 + i)^n − 1) ÷ i] × (1 + i)
- P is the monthly instalment
- n is the number of monthly instalments (10 years → 120)
- i is the monthly rate,
(1 + r)^(1/12) − 1, where r is the expected annual return (12% a year → 0.9489% a month)
With a step-up the instalment rises every 12 months, so the calculator adds up every instalment grown from its own month to the end. A lump sum grows as L × (1 + i)^n, which is the same as L × (1 + r)^years.
Why SIP calculators give different answers
Mostly because of how the yearly return is turned into a monthly rate. Many calculators divide it by 12, so 12% becomes 1% a month. Compounded over twelve months, 1% a month is 12.68% a year — more than the 12% you typed.
Fund returns over periods longer than a year are normally stated as compound annual rates (CAGR, or XIRR for SIPs), so "12% a year" means the money grew by 12% each year. That is why this calculator uses the effective monthly rate (1 + r)^(1/12) − 1 by default. To match a calculator that divides by 12, choose Nominal: r ÷ 12 under Monthly rate from annual return.
Counting instalments at the start or at the end of each month changes the result by one month of growth as well.
Inflation and today's money
Prices rise, so ₹1 crore in 20 years will buy much less than ₹1 crore today. When you enter an inflation rate, each value is divided by (1 + inflation)^years to show what it is worth in today's rupees.
In the Goal planner the target is treated as today's money and grown by inflation first, so the SIP shown is enough for what the goal will cost at that time.
Limitations
- Assumes the same return every month. Real market returns go up and down, and the order of good and bad years changes the final value of a SIP.
- Does not deduct taxes on gains, exit loads or stamp duty. Fund returns are reported after the expense ratio, so use a return that is already net of fund costs.
- The step-up is applied every 12 months from your first instalment; your fund house may let you choose a different top-up schedule.
- Past returns do not guarantee future returns.

Frequently asked questions
What return should I assume?
There is no guaranteed figure. Use a cautious rate based on the long-term history of the fund and asset class, and try a few rates — for example 8%, 10% and 12% — to see a range. Debt funds usually return less than equity funds, and equity returns swing much more from year to year.
Is the SIP invested at the start or the end of the month?
This calculator assumes the start of each month, so every instalment earns at least one month of growth. If your SIP date is late in the month, the real figure will be slightly lower.
What is a step-up SIP?
A step-up (or top-up) SIP raises the instalment at regular intervals — here every 12 months — by a percentage or a fixed amount. A ₹10,000 SIP raised by 10% a year for 10 years grows to about ₹32.7 lakh at 12% a year, against ₹22.4 lakh for a flat SIP.
Are SIP returns guaranteed?
No. Mutual fund returns depend on the markets and can be negative, especially over short periods. The calculator shows what would happen if your money grew at a steady rate, so treat the result as a planning estimate.
Lump sum or SIP — which gives more?
If markets rise steadily, a lump sum invested on day one ends higher because all the money is invested for longer. A SIP spreads your purchases over time, which reduces the risk of investing everything at a market peak and fits a monthly income. Switch modes to compare both with the same numbers.
