What Is SIP? The Systematic Investment Plan Guide
Understand Systematic Investment Plans (SIP). Learn how compounding, automation, and rupee cost averaging build wealth in mutual funds.
A Systematic Investment Plan (SIP) is a disciplined method of investing a fixed sum of money regularly into mutual funds or stock indexes. Instead of attempting to time the volatile market, a SIP automates your savings pattern, taking advantage of rupee cost averaging to accumulate shares over time.
Formula & Math Principles
SIP growth is modeled using the future value of an annuity due equation:
How to Calculate (Step-by-Step)
To compute systematic investment projections:
- Establish your fixed monthly deposit amount (P).
- Determine the expected annual return rate and convert it to monthly rate (i = rate / 12 / 100).
- Identify the overall number of monthly installments (n).
- Evaluate the annuity factor and multiply by P to obtain your maturity value (M).
Practical Examples & Scenarios
Workplace Automated SIP Plan
Investing $200 at the start of each month at a 10% expected return for 5 years (60 months).
Evaluating the annuity due equation yields a portfolio size of $15,616.56, earning over $3,600 in returns.
Maturity Projections of a $200 Monthly SIP (various return rates)
| Term | at 8% Return | at 10% Return | at 12% Return |
|---|---|---|---|
| 5 Years | $14,790 | $15,616 | $16,497 |
| 10 Years | $36,738 | $41,017 | $45,862 |
| 20 Years | $117,804 | $151,192 | $195,851 |
| 30 Years | $297,764 | $453,903 | $705,744 |
Common Pitfalls & Mistakes
- Assuming mutual fund return projections are guaranteed during bear markets.
- Stopping SIP installments during market downturns, when prices are cheapest.
