Step by Step Tutorial to Use a Percentage Formula in Excel 2013

This tutorial will guide you through the steps to use the percentage formula in Excel 2013 effectively.

Step 1: Open Microsoft Excel 2013

Open the Excel 2013 application on your computer to get started.

When you open Excel 2013, you’ll be greeted with a blank spreadsheet or the option to select a template. For percentage calculations, a simple blank spreadsheet will do just fine.

Step 2: Enter the Numbers You Want to Calculate

Type the numbers you want to perform the percentage calculation on into the cells.

Ensure that the numbers are entered correctly, and remember that Excel treats numbers with a percent sign differently than those without.

Step 3: Select the Cell Where You Want the Result to Appear

Click on the cell where you want the percentage result to be displayed.

Choosing the right cell is important because it determines where the result of your calculation will show up. Make sure it’s not a cell already containing data, as the formula will overwrite it.

Step 4: Type the Percentage Formula

Enter the percentage formula into the formula bar. The basic formula for calculating a percentage of a number is =(Part/Total)*100.

The formula bar is located at the top of your Excel worksheet, where you can enter or edit data in the selected cell.

Step 5: Press Enter to Display the Result

After typing the formula, hit enter on your keyboard to see the percentage result in the selected cell.

Once you press enter, Excel 2013 will calculate the percentage based on the formula you entered, and the result will appear in the cell you selected.

Additional Information

Using the percentage formula in Excel 2013 is just the beginning of what you can do with percentages in Excel.

Another tip is to ensure your cells are formatted correctly. Excel offers a ‘Percentage’ format, which automatically converts the decimal value into a percentage and adds the percentage symbol. To apply this, simply select the cell, right-click, choose ‘Format Cells’, and then select ‘Percentage’.

Lastly, remember that understanding the context of your data is critical. A percentage increase might look good on paper, but what does it mean in real-life terms? Always interpret your results with the bigger picture in mind.
