Annualized Return Calculator (best calculator for statistics)
Annualized Return Formula
Where:
- ARR = Annualized Rate of Return
- FV = Future Value (Final Investment Value)
- PV = Present Value (Initial Investment Value)
- T = Time Period (in years)
Variables Explained
- Present Value (PV): The initial principal amount or the starting value of the investment.
- Future Value (FV): The final value of the investment after the time period (T), including all gains, losses, and reinvestments.
- Time Period (T): The total duration of the investment, expressed in years. This must be a positive, non-zero number.
- Annualized Rate of Return (ARR): The geometric average return an investment earns each year over a specified period.

What is Annualized Return?
The Annualized Rate of Return (ARR) is a vital metric for investors and analysts as it provides a standardized, geometric average return on an investment over a specific period, usually exceeding one year. Unlike simple arithmetic returns, the ARR accounts for compounding, offering a more accurate picture of an investment’s true performance.
It allows for direct, apples-to-apples comparisons between investments with different holding periods or different compounding frequencies. By “annualizing” the return, it converts the total change in value into a rate that represents the average percentage of growth per year, assuming the growth was steady and compounded annually.
How to Calculate Annualized Return (Example)
- Identify Inputs: Suppose you invested $25,000 (PV) and after 7 years (T), the value grew to $40,000 (FV).
- Calculate the Ratio: Divide the Future Value by the Present Value: $40,000 / $25,000 = 1.6$.
- Raise to the Power of Inverse Time: Raise the ratio (1.6) to the power of $(1/7)$, which is approximately $0.142857$. $$\text{Power} = 1.6^{0.142857} \approx 1.0697$$
- Subtract One: Subtract 1 from the result to get the Annualized Rate of Return in decimal form: $1.0697 – 1 = 0.0697$.
- Final Percentage: Convert the decimal to a percentage: $0.0697 \times 100 = 6.97\%$. The Annualized Rate of Return is 6.97%.
Frequently Asked Questions (FAQ)
Is Annualized Return the same as CAGR?
Yes, they are essentially the same. CAGR (Compound Annual Growth Rate) is another term for Annualized Return, specifically when calculating the growth rate of an investment, assuming profits are reinvested.
Why can’t I use a negative Time Period (T)?
The calculation assumes a duration for growth. A negative time period is nonsensical in this context, as is an investment period of zero. The time (T) must always be greater than zero for the formula to be mathematically and practically valid.
What happens if the Future Value (FV) is less than the Present Value (PV)?
If FV < PV, the ratio $(FV/PV)$ will be less than 1. This will result in a negative Annualized Rate of Return, correctly indicating that the investment has lost value over the period.
Is this calculator suitable for monthly contributions?
No. This specific calculator is for a single lump-sum investment (Present Value). For investments with regular contributions (monthly, yearly), you should use a more complex Investment Return Calculator or a TVM (Time Value of Money) model.
