How Do I Add Times In Excel

Adding times in Excel can be a bit tricky at first, but once you understand the process, it becomes quite simple. Whether you’re adding up hours worked, calculating time spent on different tasks, or just adding up a series of times, Excel provides several methods to accomplish this. In this article, I’ll walk you through the different ways to add times in Excel and provide some helpful tips along the way.

Add Times Using the SUM Function

One of the easiest ways to add times in Excel is by using the SUM function. Simply select the cell where you want the total to appear and enter the formula =SUM(A1:A5), where A1:A5 represents the range of cells containing the times you want to add. You can also use the AutoSum button on the Home tab to quickly sum a range of cells.

Formatting Time Cells

It’s important to format your cells correctly when working with times in Excel. To ensure accurate calculations, format the cells as “Time” with the appropriate time display format. You can do this by right-clicking on the cell, selecting “Format Cells,” and then choosing the “Time” category.

Using the TIME Function

Another method for adding times in Excel is by using the TIME function. This function allows you to input specific hours, minutes, and seconds as arguments to create a time value. For example, =TIME(8,30,0) would represent 8:30 AM. You can then use the SUM function to add these time values together.

Dealing with Time Formats

Excel stores time as fractions of a day, so 24 hours is equal to 1. Therefore, when adding times, make sure to convert any hours and minutes to the appropriate decimal format. For example, 30 minutes would be expressed as 0.5 in Excel (30 minutes out of 60 minutes in an hour).


Adding times in Excel can be a valuable skill, especially for professionals who need to track and calculate time-related data. By using functions like SUM and TIME, and understanding how Excel interprets time values, you can accurately and efficiently add times in your spreadsheets.
