Understanding SIP Returns and Compound Interest in India

Systematic Investment Plan (SIP) is one of the most popular investment methods in India. By investing a fixed amount regularly in mutual funds, you benefit from rupee cost averaging and the power of compounding. Our Investment Calculator shows you exactly how your money can grow over time.

For example, a monthly SIP of ₹5,000 at 12% annual return for 15 years can grow to over ₹22 lakhs. The longer the investment period, the higher the wealth creation due to compounding. This tool uses the standard future value of annuity formula for precise projections.
