SIP full form is Systematic Investment Plan. A SIP is a method of investing in mutual funds where a fixed amount is invested at regular intervals — typically monthly. It allows investors to build wealth gradually without needing a large sum upfront.

In India, SIPs have become one of the most popular ways to invest in equity mutual funds. Millions of retail investors use SIPs to participate in financial markets without the need to time the market.

What Does SIP Stand For?

SIP stands for Systematic Investment Plan. The word "systematic" refers to the regular and disciplined nature of the investment. Instead of investing a large amount once, a SIP spreads investments over time. The word "plan" reflects the structured nature of the commitment — an investor authorises fixed automatic deductions on a chosen date each month or quarter.

How Does a SIP Work?

When you start a SIP, you choose a mutual fund scheme and a fixed investment amount. On the SIP date, the amount is automatically debited from your bank account. The fund house uses this amount to buy units of the chosen scheme at the prevailing Net Asset Value (NAV).

Over time, you accumulate units in the fund. When the NAV is high, you buy fewer units. When it is low, you buy more. This natural averaging of purchase cost is called rupee cost averaging.

Types of SIP in India

  • Regular SIP: A fixed amount invested at fixed intervals. The most common type. Suitable for salaried investors with stable monthly income.
  • Step-Up SIP: The investment amount increases annually by a fixed percentage or fixed amount. Also called a top-up SIP. Suitable for investors expecting income growth over time.
  • Flexible SIP: The investor can vary the amount invested each month based on available cash flows. Suitable for those with irregular income.
  • Trigger SIP: Investments are made only when a specific market event or index level is triggered.
  • Perpetual SIP: A SIP with no fixed end date. Continues until the investor manually stops it. Useful for long-term wealth creation goals.

What is SWP? — Related Term

SWP full form is Systematic Withdrawal Plan. It is the reverse of a SIP. In a SWP, an investor withdraws a fixed amount from an existing mutual fund investment at regular intervals. SWP is commonly used during retirement to create a regular income stream from accumulated investments.

Minimum SIP Amount in India

Most mutual funds in India allow SIPs starting from ₹100 per month, though the minimum varies by fund house and scheme. ELSS (tax-saving) funds, index funds, and large-cap funds typically allow low minimums. Some direct plans offer SIPs starting from ₹500.

How to Start a SIP in India

  1. Open a demat and trading account or register with a mutual fund distributor.
  2. Complete KYC (Know Your Customer) verification using Aadhaar and PAN.
  3. Choose a mutual fund scheme based on your investment goal and risk tolerance.
  4. Set the SIP amount, frequency (monthly, quarterly), and start date.
  5. Register the bank mandate for automatic deductions.

Once set up, the SIP runs automatically each month. Investors can pause, modify, or stop a SIP at any time by submitting a request to the fund house or through their investment platform.

SIP and Mutual Fund Regulation in India

SIPs are regulated by the Securities and Exchange Board of India (SEBI). Mutual fund houses that offer SIPs must be registered with SEBI and comply with its investment guidelines. AMFI (Association of Mutual Funds in India) oversees fund house conduct and investor protection norms.
