Utilize this powerful Annualized Return Calculator to determine the compound annual growth rate (CAGR) for any investment over a period of time. This financial tool, similar to functions found in advanced TI calculators, allows you to solve for the missing variable: Beginning Value, Ending Value, Number of Years, or the Annualized Rate.

Annualized Return Calculator Formula
The Annualized Return is calculated using the Compound Annual Growth Rate (CAGR) formula, which is a standard method in finance to determine the geometric mean rate of return.
Variables
The calculator requires you to input three of the four variables below. The missing variable will be solved for automatically.
- Beginning Value (BV): The initial investment amount (Present Value).
- Ending Value (EV): The final value of the investment after the time period.
- Number of Years (N): The length of time the investment was held (in years).
- Annualized Rate (R): The annual percentage return (CAGR) over the period.

What is Annualized Return?
Annualized return, often interchangeable with Compound Annual Growth Rate (CAGR), is the average rate of return an investment has generated per year over a specified period longer than one year. It’s considered the most accurate measure of performance because it smooths out returns, eliminating the effects of compounding fluctuations that can distort simple arithmetic averages.
In the context of financial modeling and long-term planning, the annualized rate is crucial. It allows investors to compare the performance of investments with different lifespans and initial amounts on an equal footing. For instance, comparing a 3-year investment return to a 10-year investment return is only meaningful when both are expressed as an annual average growth rate.
How to Calculate Annualized Return (Example)
Suppose you invested $50,000 and it grew to $75,000 over 7 years. Here is how the Annualized Rate (R) is calculated:
- Identify Variables: BV = $50,000, EV = $75,000, N = 7.
- Apply the Formula: $\text{R} = (\frac{75,000}{50,000})^{\frac{1}{7}} – 1$.
- Simplify Ratios: $\text{R} = (1.5)^{\frac{1}{7}} – 1$.
- Calculate Root: $\text{R} \approx 1.0596 – 1$.
- Final Result: $\text{R} \approx 0.0596$, or 5.96%.
This means your investment had an average annual growth rate of 5.96% over the seven-year period.
Frequently Asked Questions (FAQ)
What is the difference between Annual Return and Annualized Return?
Annual Return is the actual return achieved in a single calendar year. Annualized Return (CAGR) is a hypothetical geometric average that assumes the investment compounded at the same rate every year over a specified multi-year period.
Does this calculator account for deposits or withdrawals?
No. This simple Annualized Return Calculator (CAGR) assumes a single lump-sum investment at the beginning. For investments with ongoing contributions, you would need a Modified Dietz or Time-Weighted Rate of Return (TWR) calculation.
Can the Annualized Rate be negative?
Yes, if the Ending Value is less than the Beginning Value, the investment has lost money, and the Annualized Rate (CAGR) will be negative.
Is the Annualized Return always a good measure of performance?
It’s excellent for comparison but doesn’t show volatility. Two investments with the same CAGR might have had vastly different year-to-year returns (one steady, one highly volatile).
