To calculate CAGR, you need the starting value, ending value, and the investment duration in years. It shows the average annual growth rate, assuming the investment grew steadily, smoothing out short-term market fluctuations.
Formula of Compound Annual Growth Rate (CAGR)
Here's the standard CAGR formula in text form:
CAGR = [(Ending Value / Beginning Value)^(1 / Number of Years)] – 1
Once the formula is applied, the result is typically expressed as a percentage.
Example of Compound Annual Growth Rate (CAGR) Calculation
Let’s say you invested ₹1,00,000 in a stock, and its value after 5 years became ₹1,61,051.
Using the CAGR formula:
CAGR = [(161051 / 100000) ^ (1/5)] - 1
CAGR = [1.61051 ^ 0.2] - 1
CAGR ≈ 10%
So, your investment rose at an average rate of 10% per annum over 5 years.
