How It Works
A Systematic Investment Plan (SIP) lets you invest a fixed amount every month into a mutual fund. Each instalment buys units at the current NAV, giving you rupee-cost averaging over market cycles. The future value formula compounds each monthly investment separately — money invested in month 1 compounds for all n months, money in month 2 for (n−1) months, and so on. The extra × (1 + r) factor accounts for investments made at the start of each period (annuity due).
SIP Future Value Formula
M = P × {[(1 + r)ⁿ − 1] / r} × (1 + r) — where P is monthly SIP amount, r is monthly return rate (annual rate ÷ 12 ÷ 100), and n is total months.
Example: A ₹10,000/month SIP at 12% p.a. for 10 years — monthly rate r = 0.12/12 = 0.01, n = 120 months. Maturity ≈ ₹23.2 lakh on ₹12 lakh invested — a wealth gain of ₹11.2 lakh (93% returns).
The power of compounding accelerates significantly in the later years. In year 1 your portfolio grows modestly; by year 8–10, the compounding effect overtakes your fresh investments — this is why long tenure SIPs are so effective.
Key Terms
- P — Monthly SIP
- Fixed amount invested at the start of every month.
- r — Monthly rate
- Annual return ÷ 12 ÷ 100. E.g., 12% p.a. → 0.01/month.
- n — Total months
- Investment duration in months. 10 years = 120 months.
- Step-up SIP
- Annual increase in monthly SIP amount — aligns investment growth with salary hikes.
Frequently Asked Questions
What is a SIP?
A Systematic Investment Plan (SIP) is a method of investing a fixed amount regularly — typically monthly — into a mutual fund scheme. SIPs promote disciplined investing and benefit from rupee-cost averaging, buying more units when markets are low and fewer when high.
How is SIP maturity value calculated?
Maturity Value = P × {[(1 + r)ⁿ − 1] / r} × (1 + r), where P = monthly SIP amount, r = monthly return rate (annual rate ÷ 1200), and n = total number of months. This formula assumes investments at the beginning of each period.
What is a realistic SIP return rate?
Equity mutual funds in India have historically delivered 12–15% CAGR over 10+ year periods, though past performance doesn't guarantee future returns. Debt funds typically return 6–8%, while hybrid funds fall in between. Use a conservative 10–12% for long-term equity SIP projections.
What is rupee-cost averaging?
Rupee-cost averaging means you buy more mutual fund units when prices are low and fewer when prices are high, because your monthly SIP amount stays fixed. Over time, this lowers your average cost per unit compared to investing a lump sum at a single point.
What is a Step-up SIP?
A Step-up (or top-up) SIP automatically increases your monthly investment by a fixed percentage each year — typically 10–15%. This aligns your investment growth with your income growth and can significantly boost your final corpus compared to a flat SIP.
SIP vs lump sum — which is better?
SIPs are generally preferred for regular investors as they average out market volatility and require no market timing. Lump sum investing can outperform if done at a market bottom, but is riskier. For most retail investors, SIPs are the disciplined, lower-risk choice.
