SIP Growth Summary
What is SIP (Systematic Investment Plan)?
A Systematic Investment Plan (SIP) is a method of investing a fixed amount in a mutual fund at regular intervals — typically monthly. Instead of timing the market with a lump sum, SIP averages your purchase cost over time through a process called rupee cost averaging. When markets fall, your fixed investment buys more units; when markets rise, it buys fewer. Over long periods, this disciplined approach has historically generated significantly higher returns than keeping money in a bank account or FD.
SIP Return Formula
The future value of a SIP investment is calculated using the annuity formula: FV = P × [(1 + r)^n − 1] / r × (1 + r), where FV is the future corpus, P is the monthly SIP amount, r is the monthly return rate (annual rate ÷ 12 ÷ 100), and n is the total number of months. Each monthly investment compounds independently from its investment date — the first instalment compounds for the full period, while the last compounds for just one month.
SIP Growth Examples at Different Amounts and Durations
At 12% annual return: ₹5,000/month for 10 years → corpus ≈ ₹11.62 lakh (invested ₹6 lakh, wealth gained ₹5.62 lakh). ₹5,000/month for 20 years → corpus ≈ ₹49.96 lakh (invested ₹12 lakh, wealth gained ₹37.96 lakh — over 3× the invested amount). ₹10,000/month for 15 years → corpus ≈ ₹50.46 lakh (invested ₹18 lakh). These numbers demonstrate why starting early and staying invested is far more powerful than investing a larger amount later.
How Much SIP to Become a Crorepati?
This is one of the most searched questions in Indian personal finance. At 12% annual return: to reach ₹1 crore you need ₹5,500/month for 20 years, or just ₹1,100/month for 30 years. The 10-year difference cuts the required monthly amount by 80% — entirely due to compounding. At 14% return, you need only ₹2,500/month for 25 years. The key insight: time in the market is more powerful than the amount invested.
What Return Rate Should You Use for SIP Calculations?
For conservative planning, use 10–11% for large-cap equity funds — this reflects a realistic long-term historical average for Indian markets (Nifty 50 has delivered approximately 12–13% CAGR over the last 20 years). For aggressive scenarios, 12–15% may be used for mid and small-cap funds, but these carry higher short-term volatility. For hybrid or balanced funds, 8–10% is reasonable. Never treat these as guaranteed returns — mutual fund returns are market-linked and can be negative in any given year.
SIP vs FD vs RD — Long-Term Comparison
For a ₹5,000/month investment over 15 years: an RD at 7% gives approximately ₹15.5 lakh. An FD strategy at 7% gives a similar result. A SIP in an equity fund at 12% gives approximately ₹25.2 lakh — over ₹10 lakh more for the same monthly investment. Over 20 years, the gap becomes even more dramatic: RD gives ₹26.5 lakh while an equity SIP at 12% gives ₹49.96 lakh. The trade-off is market risk — in any given year, equity SIPs can decline 20–30%, unlike guaranteed-return products. For goals beyond 7 years, SIPs have historically been the superior wealth-creation tool in India.

FV = P × [(1 + r)^n − 1] / r × (1 + r), where P = monthly investment, r = monthly return rate (annual ÷ 12 ÷ 100), n = total months. Each instalment compounds from its investment date — the first for the full period, the last for one month only.
₹5,000/month at 12% for 10 years → corpus ≈ ₹11.62 lakh. Total invested = ₹6 lakh. Wealth gained = ₹5.62 lakh. Over 20 years at the same rate, the corpus grows to ₹49.96 lakh — invested ₹12 lakh, wealth gained ₹37.96 lakh.
At 12% return: ₹5,500/month for 20 years or ₹1,100/month for 30 years. At 14% return: ₹2,500/month for 25 years. Starting 10 years earlier can cut the required monthly SIP amount by 80% — this is the power of compounding over time.
For conservative planning: 10–11% (large-cap equity funds historical average). For moderate: 12% (Nifty 50 long-term CAGR). For aggressive: 12–15% (mid/small-cap, higher volatility). For hybrid funds: 8–10%. Never treat these as guaranteed — mutual fund returns are market-linked.
For 7+ year goals, equity SIPs have historically outperformed significantly. ₹5,000/month for 15 years: RD at 7% → ₹15.5 lakh; SIP at 12% → ₹25.2 lakh. The trade-off is market risk — SIPs can fall 20–30% in any year, unlike guaranteed FD/RD returns. For short-term goals under 5 years, FD or RD is safer.
