A CAGR (Compound Annual Growth Rate) calculator is an online financial tool that computes the annualised rate of return of an investment over a multi-year period — representing the equivalent constant annual growth rate that would take the investment from its beginning value to its ending value over the specified time horizon. It is calculated as: CAGR = (Ending Value ÷ Beginning Value)^(1 ÷ Number of Years) – 1. The CAGR calculator helps investors compare the actual annualised returns of different investments — stocks, mutual funds, real estate, gold, or fixed deposits — on a consistent basis regardless of holding period. For example, a mutual fund NAV growing from ₹100 to ₹217 over seven years has a CAGR of 11.7% — a cleaner performance metric than the total return of 117% which doesn't indicate the time taken. In India, SEBI mandates that mutual fund performance advertisements display CAGR figures for standardised 1-year, 3-year, 5-year, and since-inception periods — making CAGR the universal return metric in Indian fund comparisons. Ventura's CAGR calculator serves dual purposes: helping investors calculate the historical CAGR of their existing portfolio to assess performance, and working in reverse — inputting a desired future corpus and current value to determine what CAGR is needed to reach the goal within the investor's target timeline.
