If you work with numbers in Excel, you may have come across decimal values that you need to convert to whole numbers. In such cases, using the INT formula can be particularly useful. By applying the INT formula, you can truncate a decimal number down to its nearest whole number value, which can simplify calculations or clear up any confusion caused by working with decimal values. In this blog post, we’ll explore what the INT formula is, how to use it, and some practical examples to help you get started.
What is the INT formula?
The INT formula in Excel is used to convert decimal numbers to whole numbers by rounding down to the nearest integer. The formula takes one argument, which is the decimal value you want to convert into a whole number. When applying the INT formula, Excel removes any trailing numbers after the decimal point, which effectively rounds the number down to the nearest integer.
How to use the INT formula in Excel
Using the INT formula in your Excel spreadsheet is simple. Follow these steps:
Step 1: Select a cell where you want to display the whole number result
Choose a cell where you want to view your whole number result after applying the INT formula.
Step 2: Enter the INT formula
In the selected cell, type =INT( in the formula bar and then add the decimal value that you want to round down. For example, if you want to round down to the nearest whole number value for the decimal value in cell A1, the formula will be =INT(A1).
Step 3: Press enter
Press enter, and Excel will display the roundeddown whole number result in the selected cell.
Example: How to use the INT formula in Excel
Let’s say you’re managing a sales team, and you need to calculate their monthly bonuses based on the total sales they generated. You have a spreadsheet that shows each salesperson’s total sales, including the decimal values. To calculate the bonuses, you need to convert the decimal values into whole numbers.
Step 1: Select a cell where you want to display the whole number result
Choose a cell where you want to view the bonus result after applying the INT formula.
Step 2: Enter the INT formula
In the selected cell, type =INT( in the formula bar and add the cell reference for the total sales value that you want to convert into a whole number. For example, if you want to convert the total sales value in cell A1 to a whole number, the formula will be =INT(A1).
Step 3: Press enter
Press enter, and Excel will display the roundeddown whole number bonus result in the selected cell.
Using INT formula with other functions
The INT formula can be used in combination with other Excel functions such as SUM, AVERAGE, and MAX/MIN. By using the INT formula in these functions, you can round down decimal numbers to the nearest integer and perform calculations with whole numbers.
Example: Using the INT formula with SUM function
Let’s say you have a list of sales for the year, including decimal values. You want to calculate the total sales for the year, but you only want to include whole number values. Here’s how to use the INT formula with the SUM function:
 Select a cell where you want to display the total sales result
 Enter the formula =SUM(INT(A1:A12)) in the selected cell, where A1:A12 is the range of cells that contain the sales values you want to include in the calculation
 Press enter, and Excel will display the roundeddown whole number total sales result in the selected cell
Example: Using the INT formula with MAX function
Let’s say you have a list of product sales, including decimal values. You want to find the highest whole number value in the list. Here’s how to use the INT formula with the MAX function:
 Select a cell where you want to display the highest whole number result
 Enter the formula =MAX(INT(A1:A12)) in the selected cell, where A1:A12 is the range of cells that contain the sales values you want to include in the calculation
 Press enter, and Excel will display the roundeddown highest whole number result in the selected cell
Using the ROUNDUP function to round up decimal numbers
The INT formula rounds down decimal numbers to the nearest whole number by default. If you need to round up decimal numbers, you can use the ROUNDUP function. The ROUNDUP function takes two arguments – the number you want to round up and the number of digits to which you want to round up. Here’s an example:
 Select a cell where you want to display the roundedup result
 Enter the formula =ROUNDUP(A1,0) in the selected cell, where A1 is the decimal number you want to round up
 Press enter, and Excel will display the roundedup whole number result in the selected cell
Final Thoughts
The INT formula is an essential feature in Excel that can help you simplify calculations, and avoid confusion when working with decimal numbers. Knowing how to use the INT formula can save you time and effort and improve your efficiency while using Excel. With the examples and instructions provided in this blog post, you should be able to use the INT formula easily and confidently in your work.
