How to Get R2 in Microsoft Excel
Calculating the R-squared (R2) value in Microsoft Excel is a process that helps you assess the goodness of fit for your data in regression analysis. Follow these simple steps using Excel’s built-in functions to get the R2 value:
-
Step 1. Input Your Data
Enter your data into two columns in Excel. Label one column as the independent variable (X) and the other as the dependent variable (Y).
-
Step 2. Select the Data
Highlight the data you have entered, including the column labels.

Step 3. Insert a Scatter Plot
Go to the “Insert” tab on the Ribbon. In the “Charts” group, click “Scatter” and select “Scatter with only Markers” to create a scatter plot of your data.
-
Step 4. Select ‘Add Trendline’
Click on any data point in the scatter plot to highlight the series. Then, right-click and select “Add Trendline” from the context menu.
-
Step 5. Display the R2 Value
In the “Format Trendline” pane, check the box that says “Display R-squared value on chart.” Excel will automatically calculate and display the R2 value on the chart.
