SIP is the simplest way to invest in mutual funds. Put in a fixed amount every month and let compounding do the heavy lifting over time.

Short answer: a monthly SIP grows by M × ((1+r)^n − 1) ÷ r × (1+r). At 12% a year, ₹5,000 a month becomes ₹11.62 lakh in 10 years against ₹6 lakh invested — so roughly ₹5.6 lakh of it is compounding rather than contribution.

The biggest advantage of SIP is not the returns — it is the discipline. When you set up a SIP, a fixed amount is automatically deducted from your bank account every month. You do not have to remember to invest, time the market, or panic when markets fall. In fact, when markets fall, your SIP buys more units at lower prices — this is called rupee cost averaging, and it smoothens out volatility over the long term.
Consider this: if you had started a ₹5,000 monthly SIP in a Nifty 50 index fund 15 years ago, your total investment of ₹9 lakh would be worth approximately ₹25-30 lakh today. The power of starting early and staying consistent cannot be overstated. Every year you delay costs you significantly in the long run.
Starting a SIP is surprisingly simple these days. Download a SEBI-registered app like Groww, Zerodha Coin, or Kuvera — all are free. Complete KYC with PAN and Aadhaar (5 minutes). Search for a Nifty 50 Index Fund from UTI, HDFC, or ICICI. Set up a monthly SIP for whatever you can afford — even ₹500 is a perfectly fine starting point. Then forget about it and let it grow.
For beginners, index funds are the best starting point because they simply track the market index, have low expense ratios, and have outperformed most actively managed funds over 10+ year periods. You do not need to pick stocks or understand technical charts — just stay invested consistently.
