How to Calculate R Squared in Microsoft Excel
Microsoft Excel provides powerful tools to calculate R Squared, a key statistic that measures the goodness-of-fit of your regression models. Mastering this calculation is essential for accurate data analysis and interpretation.
How to Calculate R Squared in Microsoft Excel
Calculating R Squared in Microsoft Excel is a simple process once you learn how it works. Follow these steps to determine the R Squared value for your data accurately:
-
Step 1. Input Your Data
Begin by entering your data into two columns, one for the independent variable (X) and one for the dependent variable (Y).
-
Step 2. Create a Scatter Plot
Select your data, go to the “Insert” tab, and choose “Scatter” from the “Charts” group to create a scatter plot of your data points.
-
Step 3. Add a Trendline
Click on any data point in the scatter plot, then right-click and select “Add Trendline.” In the “Format Trendline” pane, choose the linear option.
-
Step 4. Display the R Squared Value
In the “Format Trendline” pane, check the box for “Display R-squared value on chart.” Excel will calculate and show the R Squared value on the scatter plot.
-
Step 5. Verify and Save Your Results
Review the displayed R Squared value to ensure it accurately represents your data. Save your workbook to preserve your chart and calculations.

FAQs
How do I calculate R Squared in Excel?
Create a scatter plot, add a trendline, and select “Display R-squared value on chart.”
Can I calculate R Squared without creating a chart?
Yes, use the RSQ function by typing “=RSQ(known_ys, known_xs)” with your data ranges.
What does R Squared represent in Excel?
R Squared measures the goodness-of-fit of your regression model, indicating how well the data points fit the regression line.
Is it possible to use multiple variables to calculate R Squared in Excel?
Yes, use the LINEST function for multiple regression to get the R Squared value among other statistics.
How do I interpret the R Squared value?
An R Squared value close to 1 indicates a good fit, while a value close to 0 indicates a poor fit.
