How to Calculate the Average Annual Rate of Return in Excel: A Guide

Calculating the average annual rate of return in Excel is a straightforward process. It involves inputting the initial and final values of your investment, the time frame, and applying the appropriate formula. By the end of this, you’ll have a clear picture of the yearly growth rate of your investment, vital for financial planning and comparison of investment opportunities.

After completing the calculations, you’ll have quantifiable data to assess the performance of your investment over time. This can inform decisions on whether to continue holding, adjust, or withdraw from the investment.


When it comes to investments, one of the most critical metrics to understand is the average annual rate of return. This figure tells you how much your investment grows each year, on average, which can help you make informed decisions about where to put your money and how well your investments are performing over time.

Knowing how to calculate the average annual rate of return is essential for investors, financial planners, accountants, or anyone interested in the financial growth of an investment. But why do it manually when Excel can crunch the numbers for you? Excel, with its powerful financial formulas, can save you time and reduce the chance of errors. Whether you’re evaluating stocks, bonds, real estate, or any other investment, understanding how to perform this calculation in Excel is a valuable skill to have in your financial toolkit.

Step by Step Tutorial: Calculating the Average Annual Rate of Return in Excel

Before diving into the steps, it’s important to know that the average annual rate of return represents the compounded growth rate of an investment over a period. This calculation provides insights into the performance of an investment, allowing investors to compare different opportunities.

Step 1: Gather your investment data

Input the initial and final values of your investment and the number of years it was invested.

In this step, you’ll need to have the initial value (the amount you initially invested), the final value (the amount your investment is worth now), and the time frame in years. Make sure this information is accurate and ready for input into Excel.

Step 2: Open Excel and input your data

Create a new Excel worksheet and enter your investment data into the spreadsheet.

Once you have your investment data, open up Excel and input this data into a new spreadsheet. Organize your data clearly, with labels, so that you know which number is which. This will make the subsequent steps easier.

Step 3: Use the RATE function

In an empty cell, type in the RATE function formula to calculate the average annual rate of return.

Excel’s RATE function is what you’ll use here. This function requires three pieces of data: the number of periods (years), the initial value, and the final value of your investment. Your formula should look something like this:

Step 4: Interpret the results

Once you’ve input the formula, press Enter, and Excel will calculate the average annual rate of return for you.

After hitting Enter, the cell will display the average annual rate of return, expressed as a decimal. To convert this into a percentage, multiply the result by 100. This percentage is the compounded annual growth rate of your investment.

Limited ScopeExcel’s calculation only takes into account the values provided and does not consider other investment factors like taxes or fees.

Additional Information

While the steps above will get you to the average annual rate of return in Excel, it’s important to remember a few things. Excel is a powerful tool that assumes the data you input is correct. Garbage in, garbage out, as they say. Always double-check your data before running calculations. Additionally, the average annual rate of return doesn’t tell the whole story of an investment. It doesn’t account for potential taxes, transaction fees, or market fluctuations. It’s a snapshot, not a full movie.

Another tip is to ensure that you format the result as a percentage to avoid confusion. Also, remember that the RATE function in Excel calculates the rate assuming compounding, which is the case for most investments but not all. Be mindful of the type of investment you’re evaluating.
