What is SIP? How Systematic Investment Plan Works in Global
What is SIP?
A Systematic Investment Plan (SIP) allows you to invest a fixed amount in a mutual fund at regular intervals — monthly, weekly, or quarterly.
Instead of investing a large lump sum at once, you invest small, consistent amounts. This makes investing accessible to everyone — even with ₹500/month.
How SIP Works
- 1You choose a mutual fund (e.g., HDFC NIFTY 50 Index Fund)
- 2You set an amount (e.g., ₹5,000/month) and a date (e.g., 1st of every month)
- 3The amount is automatically debited from your bank account
- 4You receive units of the mutual fund at that day's NAV
- 5Over time, you accumulate units — the value grows as the fund's NAV rises
The Power of Rupee Cost Averaging
When you invest a fixed amount every month:
- When NAV is high, you buy fewer units
- When NAV is low, you buy more units
This automatically averages your purchase cost over time — you don't need to "time the market." This is called Rupee Cost Averaging (RCA).
The Power of Compounding
Albert Einstein called compound interest the "eighth wonder of the world."
With a ₹10,000/month SIP at 12% annual return:
| Years | Total Invested | Estimated Value |
|---|---|---|
| 5 | ₹6,00,000 | ₹8.2 Lakh |
| 10 | ₹12,00,000 | ₹23.2 Lakh |
| 20 | ₹24,00,000 | ₹99.9 Lakh |
| 30 | ₹36,00,000 | ₹3.53 Crore |
The longer you stay invested, the more powerful compounding becomes.

Types of SIP
Regular SIP: Fixed amount every month — the most common type.
Step-up SIP (Top-up SIP): Your investment amount increases by a fixed % each year. E.g., start with ₹5,000/month and increase 10% annually. This mirrors your income growth.

Flexible SIP: You can change the amount each month.
