Calculate Annual Rate of Return

The annual rate of return (ARR) is a fundamental metric used to evaluate the profitability of an investment over a specific period, typically one year. It represents the percentage gain or loss on an investment relative to its initial cost.

Understanding your ARR helps you compare different investment opportunities, assess the performance of your portfolio, and make informed decisions about where to allocate your capital. A higher ARR generally indicates a more successful investment.

In Excel, you can easily calculate the ARR using a simple formula. The core components you'll need are the initial value of your investment and its final value after a specified period (usually one year).

How to Calculate Annual Rate of Return

The formula for calculating the annual rate of return is as follows:

Annual Rate of Return = ((Ending Value – Beginning Value) / Beginning Value) * 100

Let's break down the components:

  • Beginning Value: This is the initial amount invested.
  • Ending Value: This is the value of the investment at the end of the period (e.g., one year).

By entering these values into our calculator, you can quickly determine your investment's performance.
