In the world of finance and investing, understanding returns accurately is key to making informed decisions. One powerful tool that helps investors measure performance over time is the CAGR formula. Often used in mutual funds, stocks, business growth analysis, and more, the CAGR Calculator simplifies complex return data into a single, annualized growth rate.
What is CAGR?
CAGR stands for Compound Annual Growth Rate. It is a mathematical formula used to calculate the mean annual growth rate of an investment over a specific period of time, assuming profits are reinvested each year.
Unlike average annual returns, CAGR smooths out fluctuations and presents a consistent rate of growth—ideal for comparing different investments over time.
The CAGR Formula
The CAGR formula is:
CAGR=(Ending ValueBeginning Value)1n−1\text{CAGR} = \left( \frac{\text{Ending Value}}{\text{Beginning Value}} \right)^\frac{1}{n} - 1CAGR=(Beginning ValueEnding Value)n1−1
Where:
Ending Value = Value of the investment at the end of the period
Beginning Value = Value at the start of the period
n = Number of years\
Example:
Suppose you invested ₹1,00,000 in 2020, and by 2025 it grew to ₹1,61,000.
CAGR=(161000100000)15−1=(1.61)0.2−1≈0.10 or 10%\text{CAGR} = \left( \frac{161000}{100000} \right)^\frac{1}{5} - 1 = (1.61)^{0.2} - 1 \approx 0.10 \text{ or } 10\%CAGR=(100000161000)51−1=(1.61)0.2−1≈0.10 or 10%
This means your investment grew at an average rate of 10% per annum over five years.
Why Use a CAGR Calculator?
Manually calculating CAGR using the formula is straightforward, but for multiple investments or long durations, using a CAGR calculator is much faster and error-free. These online tools allow you to enter the start value, end value, and number of years—instantly returning the CAGR result.
Benefits of Using a CAGR Calculator:
Saves time on complex calculations
Useful for quick comparisons of investment options
Helpful in business revenue or sales analysis over time
Eliminates manual errors in large datasets
Applications of CAGR in Real Life
