How to Increment a Number in Excel: Step-by-Step Guide

Incrementing a number in Excel is a simple task that involves using basic formulas or functions. Simply put, you can either manually add a specific value to a number or use the fill handle to drag and auto-increment the values down a column or across a row. After this action, the cells you’ve selected will display a series of numbers increased by the value you’ve specified.

After completing this action, the numbers in the cells you’ve selected will be incremented by the value you chose. This can be particularly useful when working with numerical data that requires sequential order, such as invoice numbers, days of a month, or serial numbers.


Excel is a powerful tool that we often take for granted. It’s easy to think of it as just a giant calculator, but it’s so much more. Among its many features is the ability to increment numbers, which is one of the fundamental tasks that Excel users need to know. This skill is crucial for creating organized data sets, performing calculations on a series of numbers, and managing lists that require sequential numbering. Whether you’re a business professional analyzing financial data, a researcher organizing study results, or a student creating a project timeline, knowing how to increment a number in Excel will save you time and enhance your spreadsheets’ functionality.

For those who think that such a simple task doesn’t warrant much attention, think again. Excel’s increment feature is the bedrock upon which complex formulas and data analysis tools are built. So, let’s dive in and get you started on mastering this essential Excel task.

Step by Step Tutorial: Incrementing a Number in Excel

Before diving into the steps, it’s important to understand that incrementing a number in Excel means increasing its value by a specific amount in a patterned sequence.

Step 1: Enter the starting number

Type your starting number into a cell.

This step is pretty straightforward. The number you type in is where your sequence will begin. It could be any number, depending on what you require for your data set.

Step 2: Use the fill handle to drag down or across

Click and drag the fill handle from the bottom-right corner of the cell down the column or across the row.

After typing in your starting number, you’ll notice a little square at the bottom-right corner of the cell. That’s the fill handle. Clicking and dragging it down or across will copy the number to the other cells.

Step 3: Release the fill handle and choose ‘Series’

After releasing the mouse, a small box or ‘Auto Fill Options’ will appear. Select ‘Series’ from this box.

Selecting ‘Series’ will open up a dialog box that gives you various options for how you want your numbers to increment.

Step 4: Set the step value and stop value

In the ‘Series’ dialog box, set the ‘Step value’ to define by how much each number should increase. Set the ‘Stop value’ to define where the sequence should end.

The step value is the amount by which each number in the sequence will increase. The stop value is the number at which the sequence will stop. This step is crucial for ensuring your sequence increments the way you want it to.

Step 5: Click OK

Click ‘OK’ in the ‘Series’ dialog box to apply the sequence to your selected cells.

Clicking ‘OK’ will execute the action and your cells will now display an incremented sequence of numbers.


Saves TimeIncrementing numbers manually can be time-consuming, particularly for large data sets. Using Excel to increment numbers automates the process, allowing you to fill hundreds of cells with sequential numbers in seconds.
Reduces ErrorsManual entry is prone to errors, as it’s easy to lose count or skip numbers. An automated increment ensures accuracy across the board.
CustomizableThe ability to set the step value allows you to customize the increments to your specific requirements, whether you need to count by twos, fives, tens, or any other interval.


Limited to Linear SequencesExcel’s basic increment feature is limited to linear sequences. For more complex patterns, additional formulas or programming may be required.
Can Be OverwrittenIf you’re not careful, dragging the fill handle can overwrite existing data. It’s important to check that the cells you’ll be filling are empty.
Requires Understanding of ExcelFor a beginner, understanding how to increment numbers and access the ‘Series’ dialog box might not be intuitive. A basic understanding of Excel’s interface is necessary.

Additional Information

While we’ve covered the basics of incrementing a number in Excel, there are a few more tricks worth mentioning. One such trick is using the ROW or COLUMN function to increment numbers based on the row or column number. This can be particularly useful when you want to create a dynamic data set that automatically adjusts the sequence as you add or remove rows and columns.

Another useful tip is to combine incrementing with other Excel functions to create more complex formulas. For example, you can use the incremented numbers as part of a SUM function to add up a running total. Or you could use the increment as part of an IF statement to create conditional formatting rules. The possibilities are virtually endless once you start experimenting with different combinations.

Remember, the key to mastering Excel is practice. Don’t be afraid to try out different settings in the ‘Series’ dialog box to see how they affect your sequence. And if you ever get stuck, Excel’s help feature and online forums are full of knowledgeable users who can offer assistance.


  1. Enter the starting number into a cell.
  2. Use the fill handle to drag down or across.
  3. Release the fill handle and choose ‘Series’.
  4. Set the step value and stop value in the ‘Series’ dialog box.
  5. Click OK to apply the sequence.

Frequently Asked Questions

What if I want to increment by a number other than 1?

In the ‘Series’ dialog box, set the ‘Step value’ to whatever number you want to increment by.

Can I increment dates or times in Excel?

Yes, Excel can increment dates and times using the same steps, but you’ll need to select ‘Date’ or ‘Time’ in the ‘Series’ dialog box and adjust the step value accordingly.

How do I increment a number across a row instead of down a column?

The process is the same; just drag the fill handle across the row instead of down the column.

Can I increment numbers in a non-linear sequence?

Yes, but you will need to use more advanced formulas or functions. The basic increment feature is for linear sequences only.

What if I need to increment a number by a decimal or fraction?

You can set the ‘Step value’ to a decimal or fraction in the ‘Series’ dialog box to increment by that amount.


Knowing how to increment a number in Excel is a key skill that can help you organize and analyze data more efficiently. From creating sequential lists to performing complex data operations, the ability to automate number incrementation is a significant time saver. Whether you’re a student, a professional, or just someone looking to streamline your spreadsheet tasks, mastering this feature will undoubtedly elevate your Excel game.

So go ahead, give it a try, and watch your productivity soar. And remember, as with any new skill, practice makes perfect. Don’t be afraid to experiment with different sequences and formulas. The more you use Excel, the more you’ll discover just how versatile and powerful it can be. Incrementing a number may seem like a small step, but it’s one that opens up a world of possibilities.
