Mathematical Formula & Logic
Step-by-Step Worked Calculation
Scenario: Computing Portfolio Growth from $10k to $25k
Calculate the CAGR for an investment that grew from $10,000 to $25,000 in 5 years.
Step 1: Divide Ending by Beginning: 25,000 / 10,000 = 2.5.
Step 2: Raise to the 1/5th power: 2.5 ^ 0.2 = 1.2011.
Step 3: Subtract 1 to get decimal rate: 1.2011 - 1 = 0.2011.
Step 4: Multiply by 100 for percent: 20.11% CAGR.
How to Use the CAGR Calculator
- 1. Enter the starting (Beginning) value of your investment.
- 2. Enter the final (Ending) value of your investment.
- 3. Enter the total duration/period in years.
- 4. Review the annualized CAGR percentage and total return rate.

What is a CAGR calculator?
A CAGR calculator computes the compound annual growth rate of an investment over a specified time period, showing the smooth annual rate of return.
What is CAGR?
Compound Annual Growth Rate — the constant annual rate of return that would be needed for an investment to grow from its beginning balance to its ending balance.
What is compound growth?
Growth where returns are added to the principal each period, so returns themselves earn returns in subsequent periods.
What is the CAGR formula?
CAGR = (Ending Value / Beginning Value)^(1/Number of Years) - 1
What is beginning value?
The initial amount of the investment at the start of the period.
What is ending value?
The final amount of the investment at the end of the period.
What is the time period?
The number of years over which the investment growth is measured.
What is annual growth rate?
The yearly percentage increase or decrease in an investment's value.
What is average annual return?
The arithmetic mean of yearly returns, which differs from CAGR due to compounding effects.
What is the difference between CAGR and ROI?
CAGR shows annualized growth; ROI shows total return over the entire period without annualizing.
What is investment horizon?
The length of time an investor plans to hold an investment.
What is total return?
The overall gain or loss on an investment over a specific period.
What is annualized return?
A return expressed as a yearly rate, allowing comparison across different time periods.
What is portfolio growth?
The increase in value of a collection of investments over time.
What is market benchmark?
A standard against which investment performance can be measured.
