What is SIP?

A SIP allows you to invest as little as ₹500 per month into a mutual fund scheme of your choice. Unlike a lump-sum investment, a SIP spreads your investment over time, which protects you from investing all your money at a market peak.

Rupee-cost averaging is the key advantage: when the market falls, your fixed SIP amount buys more fund units at a cheaper price. When the market rises, the units you bought cheaply are now worth more. Over a long period (10–20 years), this averaging effect significantly improves returns compared to trying to 'time the market'.

SIP returns are calculated using the compound interest formula. A ₹5,000/month SIP at a 12% annual return over 10 years grows to approximately ₹11.6 lakhs — despite investing only ₹6 lakhs. The extra ₹5.6 lakhs is pure compounding return.

SIP stands for Systematic Investment Plan. It is not an investment product by itself. It is a way of buying a mutual fund: instead of investing a large amount once, you instruct your bank to move a fixed sum, for example ₹5,000, into a chosen fund on a fixed date each month.

People often ask whether SIP means the same as a mutual fund. It does not. The mutual fund is the thing you own, and the SIP is the schedule you use to buy it. The same fund can be bought through a SIP or through a one-time lump sum.

If you invest ₹5,000 a month and the fund earns an assumed 12% a year, the corpus after 10 years is about ₹11.6 lakh on ₹6 lakh invested. Run the same SIP for 20 years and it grows to about ₹50 lakh on ₹12 lakh invested. Doubling the time does far more than doubling the result, which is why starting early matters more than the monthly amount.

These figures are illustrations, not promises. Equity mutual fund returns are market-linked and vary year to year, so the 12% in an example is an assumption you can change in the SIP Calculator.

Stopping the SIP when markets fall is the biggest one. A falling market is exactly when a fixed amount buys more units, so pausing defeats the rupee-cost-averaging idea. Equally, a SIP does not guarantee profit or remove market risk, and it cannot rescue a poorly chosen fund.

Choose the fund by your goal and time horizon: an equity fund for goals seven or more years away, a debt or hybrid fund for shorter ones. Review once a year, and consider a step-up SIP that raises your instalment as your income grows. Read the scheme documents before investing, as this site does not give personalised investment advice.
