How to Use the Less Than or Equal to Option in Excel: A Step-by-Step Guide

Using the less than or equal to option in Microsoft Excel is rather simple. By using the function “<=” in a formula, you can compare two values and determine if one is less than or equal to the other. This feature is useful for various tasks such as filtering data, setting up conditional formatting, or establishing criteria within functions like COUNTIF or SUMIF.

After using the less than or equal to option, Excel will return a TRUE or FALSE value based on whether the condition is met. This can then be utilized in decision-making processes throughout your spreadsheet.


Microsoft Excel, that trusty software that’s used by millions around the world for data analysis, accounting, and much more. One of the powerful tools at your disposal in Excel is the ability to perform logical tests – comparing values to see how they stack up against each other. Enter the less than or equal to operator, a handy little function that allows you to compare numbers, dates, and even text strings.

Why is this important, you ask? Imagine you’re a teacher looking to quickly identify students who scored below a certain grade, or a business owner trying to track inventory levels that have dipped below a certain threshold. In these scenarios, the less than or equal to operator becomes incredibly useful. It’s a function that’s relevant to users across all levels of Excel proficiency, from the casual user maintaining a household budget to the data analyst crunching large datasets.

Step by Step Tutorial: Using the Less Than or Equal to Option in Excel

This tutorial will guide you through the process of using the less than or equal to function in Excel. By the end of it, you’ll be able to apply this logical test in various scenarios within your spreadsheet.

Step 1: Choose the Cell Where You Want the Comparison to Occur

Select the cell where you want the result of the less than or equal to comparison to appear.

This cell will display the outcome of the comparison – either TRUE if the condition is met or FALSE if it is not. You can reference this cell in other formulas or use it to filter and sort your data.

Step 2: Enter the Formula

Type the formula into the selected cell. The formula should follow this structure: =A1<=B1.

In this formula, A1 and B1 are cell references that can be changed based on your data. A1 represents the value you want to compare, and B1 is the value you’re comparing it against.

Step 3: Press Enter

After typing the formula, hit the Enter key to execute the comparison.

Once you press Enter, Excel will perform the comparison and the result will appear in the cell you selected in Step 1. If you want to compare a range of cells, you can drag the fill handle to copy the formula to adjacent cells.


Simplifies Data AnalysisUsing the less than or equal to operator can swiftly filter through a dataset to highlight specific data points, making analysis quicker and more efficient.
Versatile Across FunctionsThis operator can be used in various functions, such as SUMIF or COUNTIF, to apply criteria that will add or count only the values that meet the condition.
Facilitates Conditional FormattingApplying this logical test can help set up conditional formatting rules that automatically format cells based on whether they meet the specified criteria.


Limited to Binary OutcomesThe less than or equal to operator only provides a TRUE or FALSE outcome, which may not be sufficient for complex analyses that require more nuanced results.
Potential for ErrorsIf not used correctly, this function can lead to errors in analysis, especially if the wrong cell references are used or the data is not consistent.
Requires Understanding of LogicUsers must have a basic understanding of logical operators and how they work in Excel to effectively use this feature.

Additional Information

When diving into the less than or equal to option in Excel, it’s crucial to remember that this function is case-insensitive when dealing with text strings. This means that Excel sees “apple” and “Apple” as the same value. Additionally, you can combine the less than or equal to function with other logical operators, like AND or OR, to create more complex criteria.

Another tip is to use absolute cell references (by adding a $ before the column letter and/or row number) if you plan to copy the formula across multiple cells. This ensures that the comparison is always made against the specific cell you initially chose.

Lastly, you can use the less than or equal to option within Excel’s Graphical User Interface (GUI) for filtering data. By selecting a column and using the filter dropdown, you can set a criterion based on the less than or equal to function without writing a formula.
