How to use it
- Choose Monthly SIP (a fixed amount every month) or Lumpsum (a one-time investment).
- Enter the amount, the return you expect per year and the number of years — type the numbers or drag the sliders.
- For a SIP, optionally add a yearly step-up, for example 10% if you plan to raise your SIP with every salary hike.
- Read the estimated maturity value, invested amount and estimated returns. Tap “Show yearly growth” for the year-by-year table.
How the SIP calculator works
A SIP (Systematic Investment Plan) puts the same amount into a mutual fund every month. Like most Indian SIP calculators, this one assumes each instalment is invested at the start of the month and grows at a fixed monthly rate:
FV = P × [((1 + r)ⁿ − 1) ÷ r] × (1 + r)
- P = monthly SIP amount
- r = expected annual return ÷ 12 ÷ 100
- n = number of monthly instalments (years × 12)
Worked example
₹10,000 a month for 10 years at an expected 12% a year:
- r = 12 ÷ 12 ÷ 100 = 0.01, and n = 10 × 12 = 120
- (1.01)¹²⁰ ≈ 3.3004, so ((1.01)¹²⁰ − 1) ÷ 0.01 ≈ 230.04
- FV = 10,000 × 230.04 × 1.01 ≈ ₹23,23,391
- You invest ₹12,00,000, so the estimated returns are about ₹11,23,391.
For a lumpsum, the calculator uses yearly compounding: FV = P × (1 + R ÷ 100)ᵗ. ₹1,00,000 for 10 years at 12% becomes 1,00,000 × 3.1058 ≈ ₹3,10,585.
Time matters more than you think
The same ₹10,000 monthly SIP at an assumed 12% a year, left for different periods:
| Period | You invest | Estimated value |
|---|---|---|
| 5 years | ₹6,00,000 | ₹8,24,864 |
| 10 years | ₹12,00,000 | ₹23,23,391 |
| 15 years | ₹18,00,000 | ₹50,45,760 |
| 20 years | ₹24,00,000 | ₹99,91,479 |
| 25 years | ₹30,00,000 | ₹1,89,76,351 |
These are calculations at a constant rate, not predictions. Real returns go up and down from year to year, but the table shows why starting early helps: in later years the growth on earlier growth does most of the work.
What is a step-up SIP?
A step-up (or top-up) SIP raises your monthly instalment by a fixed percentage every year. Starting at ₹10,000 with a 10% yearly step-up, you would invest ₹11,000 a month in year 2, ₹12,100 in year 3, and so on. Over 10 years at an assumed 12%, that works out to about ₹19.12 lakh invested and an estimated ₹33.74 lakh, compared with ₹23.23 lakh for a fixed SIP.
Read the result with care
- Returns are not guaranteed. Mutual fund investments are subject to market risks. Equity funds can fall in value, sometimes for years, and past returns do not promise future ones. Read the scheme documents before investing.
- It is slightly optimistic. Dividing the yearly rate by 12 compounds to a little more than that rate: 1% a month is about 12.68% a year, not 12%. Fund returns are usually quoted as yearly CAGR or XIRR, so treat the result as a rough upper estimate.
- Costs and taxes are not included. Expense ratios, exit loads and capital-gains tax reduce what you actually receive.
