How to Do a Sensitivity Analysis in Microsoft Excel

Microsoft Excel makes sensitivity analysis accessible for anyone looking to understand how different variables impact their outcomes. Whether you’re a business professional or financial analyst, learning how to perform a sensitivity analysis in Excel can enhance your decision-making process.

How to Do a Sensitivity Analysis in Microsoft Excel

Performing a sensitivity analysis in Microsoft Excel is a powerful way to understand how changes in key variables impact your results. Follow these simple steps to conduct a sensitivity analysis effectively.

• Step 1. Prepare Your Data

Begin by organizing your data clearly and logically. Input your key variables and their respective values into the Excel sheet. Make sure you have a formula that connects these variables to your outcome of interest.

• Step 2. Create a ‘Data Table’

Select the range of cells where you want the data table to appear. Go to the “Data” tab, click on “What-If Analysis,” and then select “Data Table.”

• Step 3. Set Up the ‘Data Table’

In the dialog box that appears, you’ll need to specify the row and column input cells. These cells correspond to the variables you want to analyze. For a one-variable “data table” use only one input cell. For a two-variable data table, use both row and column input cells.

• Step 4. Input Variable Values

Enter the range of values you want to test for each variable in the appropriate rows or columns. This will allow Excel to calculate the outcome for each combination of variable values.

• Step 5. Analyze the Results

Once you’ve set up your data table, Excel will automatically populate it with results based on the different input values. Analyze these results to see how changes in your key variables affect the outcome. For more complex analyses, consider using Excel’s Scenario Manager. This tool allows you to create and save scenarios with varying input values. Access it through the “Data” tab under “What-If Analysis” and compare multiple scenarios to understand the potential range of outcomes.
