What is a SIP?
A Systematic Investment Plan (SIP) is a way of investing a fixed amount at regular intervals, usually every month, in a mutual fund or similar investment. Instead of trying to time the market with a lump sum, you invest steadily. When prices are low, your fixed amount buys more units; when prices are high, it buys fewer. This is known as rupee-cost or dollar-cost averaging. Similar monthly plans exist worldwide, often called regular savings plans or automatic investment plans.
How the SIP calculator works
For a fixed monthly amount, the standard SIP formula is:
FV = P × ((1 + i)n − 1) ÷ i × (1 + i)
- P is the monthly investment.
- i is the monthly rate of return: the annual rate ÷ 12 ÷ 100.
- n is the number of monthly installments.
The final “× (1 + i)” reflects that each installment is invested at the start of the month and grows for that month. With a step-up, the calculator simulates every month individually and raises the installment at the start of each new year.
Example
Investing 5,000 per month for 10 years at an expected 12% a year means investing 600,000 in total. The estimated value at the end is about 1,161,695, of which about 561,695 is growth.
With a 10% annual step-up (5,000 in year 1, 5,500 in year 2, and so on), you invest about 956,245 and the estimated value rises to about 1,687,163.
The power of time
Compounding means returns themselves start earning returns. That makes the length of time you stay invested one of the biggest drivers of the final value, often more important than the exact monthly amount. Try changing the period from 10 to 20 years in the calculator: the invested amount doubles, but the estimated value grows by far more than double.
Important to remember
- Returns are not guaranteed. Equity and hybrid funds go up and down. The calculator assumes a constant return every year, which real markets never deliver.
- Use conservative assumptions. Plan with a return you would be comfortable with if markets underperform.
- Costs and taxes are not included. Fund expense ratios, exit loads and capital-gains taxes reduce your actual returns.
- Inflation reduces purchasing power. A future value in today’s money will buy less than the same amount today.
