The **Annualized Return Calculator** is an essential tool for investors to determine the geometric mean rate of return that was earned on an investment over multiple periods. This is often referred to as the Compound Annual Growth Rate (CAGR).

Annualized Return Calculator Formula
The Annualized Return Rate (R), or Compound Annual Growth Rate (CAGR), is typically calculated using the following formula:
Variables
To use the calculator, you need to provide three of the four variables below. The calculator will solve for the missing one.
- Beginning Investment Value (P): The initial amount of money invested.
- Ending Investment Value (V): The final value of the investment after T years.
- Number of Years (T): The total time period (in years) the investment was held.
- Annualized Return Rate (R): The geometric mean rate of return you wish to solve for (or use to solve for other variables).

What is Annualized Return?
Annualized return provides a single number that expresses the annual rate of return earned on an investment over a specified holding period longer than one year. It’s crucial because it smooths out the effects of compounding and makes it easier to compare the performance of different investments, regardless of how long they were held.
Unlike simple arithmetic averages, the Annualized Return (CAGR) takes into account the compounding effect. This means it represents the theoretical rate at which the investment would have grown if it compounded at the same rate every year, making it a more accurate representation of investment performance.
How to Calculate Annualized Return (Example)
Let’s find the Annualized Return (R) for an investment that grew from $10,000 to $15,000 over 5 years.
- Identify Variables: P = $10,000, V = $15,000, T = 5 years. R is missing.
- Apply Formula: $$R = \left( \frac{15,000}{10,000} \right)^{\frac{1}{5}} – 1$$
- Calculate Ratio: $$R = (1.5)^{\frac{1}{5}} – 1$$
- Solve Exponent: $$R = 1.08447 – 1$$
- Final Result: R = 0.08447 or 8.45%.
Frequently Asked Questions (FAQ)
Is Annualized Return the same as CAGR?
Yes, for most practical purposes in finance, the Annualized Return refers to the Compound Annual Growth Rate (CAGR), which is the geometric mean rate of return.
Why is CAGR better than Average Return?
CAGR (Annualized Return) is superior because it accounts for compounding. The average return is an arithmetic mean that ignores the path-dependency of returns, often overstating the actual growth rate achieved.
What is the difference between Simple and Compound Annualized Return?
Simple Annualized Return typically refers to the average annual return without considering compounding, while Compound Annualized Return (CAGR) is the rate that includes the compounding effect, making it the standard for long-term investment analysis.
Can the Annualized Return be negative?
Yes. If the Ending Value (V) is less than the Beginning Value (P), the investment has lost money over the period, and the resulting Annualized Return (R) will be negative.
