Compound Annual Growth Rate Calculator
Understanding how your investment grows over time is essential for making informed financial decisions. The Compound Annual Growth Rate (CAGR) Calculator helps you determine the average annual growth rate of an investment over a specified period, assuming profits are reinvested.
CAGR provides a smoothed annual rate that shows how much an investment would have grown each year if it had grown at a steady rate.
What Is Compound Annual Growth Rate (CAGR)?
CAGR represents the annualized rate of return over a given time period.
It answers the question:
“If my investment grew at a steady rate each year, what would that rate be?”
It is widely used in:
- Investment analysis
- Business revenue growth tracking
- Stock market evaluation
- Portfolio performance comparison
Required Inputs
To calculate CAGR, you need:
- Initial investment value
- Final investment value
- Number of years
These three inputs are essential.
CAGR Formula
CAGR = (Final Value ÷ Initial Value)^(1 ÷ Number of Years) − 1
The result is expressed as a percentage.
How the Calculator Works
Step 1: Divide Final Value by Initial Value
Step 2: Raise the result to the power of (1 ÷ years)
Step 3: Subtract 1
Step 4: Convert to percentage
The calculator performs these steps instantly.
How to Use the CAGR Calculator
- Enter starting value
- Enter ending value
- Enter number of years
- Click Calculate
The result will show the average annual growth rate.
Practical Example
Suppose:
- Initial investment: $10,000
- Final value after 5 years: $18,000
CAGR = (18,000 ÷ 10,000)^(1/5) − 1
Result ≈ 12.47% annual growth
This means your investment grew at an average rate of 12.47% per year.
Why CAGR Is Important
1. Performance Comparison
Compare different investments fairly.
2. Long-Term Planning
Estimate future growth potential.
3. Business Growth Analysis
Measure revenue expansion.
4. Portfolio Evaluation
Understand average returns over time.
