SIP Calculator
Enter your monthly investment, the annual return you expect and the number of years, and see how much the plan could grow to — invested capital, gains and final value side by side.
How the SIP projection works
A SIP invests a fixed amount every month, so each instalment compounds for a different length of time — the first payment grows for the full horizon, the last one for a single month. The standard future-value formula for this is FV = M × ((1+i)ⁿ−1)/i × (1+i), where M is the monthly amount, i the monthly rate and n the number of months.
The projection assumes the return is the same every month. Real fund returns vary year to year, so treat the output as a planning estimate, not a promise — and test a pessimistic rate alongside the optimistic one.
Choosing a realistic return
Equity funds have historically delivered roughly 10–14% annualised over long periods in many markets, with deep drawdowns along the way; debt funds sit lower but steadier. A practical habit is to project three cases — conservative, base and optimistic — and plan around the middle one.
The growth multiple (final ÷ invested) shows the power of staying invested: at 12% a year, a 10-year SIP roughly doubles your money; extending to 15 years pushes the multiple past 2.5× because the early instalments compound the longest.
Common uses
Goal planning. Work backwards: enter a target horizon, see the projected value, and adjust the monthly amount until it covers the goal.
Step-up decisions. Compare what adding a small amount every month does over the same horizon — the difference compounds faster than most people expect.
Discipline check. Seeing the gap between invested and final value is a reminder that time in the market, not the amount, drives most of the outcome.
Frequently asked questions
What is a SIP?
A Systematic Investment Plan invests a fixed amount into a fund at a fixed interval — usually monthly. It averages your purchase cost over time and builds the habit of investing.
Is the projected value guaranteed?
No. The calculation compounds your inputs at a constant rate. Market-linked investments move up and down, so actual results will differ — usually less for short horizons, closer for long ones.
Why does the last month get multiplied by (1+i)?
The formula treats instalments as invested at the start of each month, so the final month earns one month of return. It is the convention most SIP calculators use.
What return should I enter?
Use a range rather than a single number. A common exercise is 8% (conservative), 12% (base) and 15% (optimistic) for equity-oriented plans, and 6–7% for debt-oriented ones.
Are taxes and fees included?
No. The projection is gross of expense ratios, exit loads and capital-gains tax. Net results will be somewhat lower, especially over short horizons.
Can I share a specific projection?
Yes — amount, rate and years travel in the URL, so a shared link reopens the exact numbers.
