How to Find the Percentage of Two Cells in Excel: A Step-by-Step Guide

Calculating the percentage of two cells in Microsoft Excel is as simple as dividing one cell by another and then multiplying the result by 100. This basic formula can be used to quickly find percentages, which can be particularly useful for financial analysis, grading, or comparing data.

After completing the action, the cell where the formula is entered will display the percentage value calculated from the two cells. This percentage can then be formatted to show the percentage symbol or to limit the number of decimal places.


Calculating percentages is a fundamental skill in data analysis, and Microsoft Excel is a powerful tool that makes this task easier. Whether you’re a student assessing your grades, a business owner analyzing sales data, or a researcher examining survey results, knowing how to find the percentage of two cells is essential. The process is not only quick but also incredibly versatile, allowing you to gain insights and make decisions based on quantitative data.

Imagine you want to know what percentage of your monthly budget you’ve spent, or maybe you need to calculate the percentage increase in sales from one quarter to the next. Excel can handle these calculations with ease. But why is this so important? Well, percentages are a way to understand relationships between numbers, putting them on a level playing field for comparison. In a world increasingly driven by data, Excel proficiency can give you an edge in numerous professional and academic settings.

Step by Step Tutorial: Finding the Percentage of Two Cells in Excel

The following steps will guide you through the process of calculating the percentage of two cells in Microsoft Excel.

Step 1: Identify the Cells

Select the two cells you want to use for your percentage calculation.

In this step, you need to determine which cell will be divided by the other. Typically, you would divide a part by the whole. For instance, if you’re looking to find out what percentage of your total sales a single product makes up, the product’s sales would be the numerator (dividend), and the total sales would be the denominator (divisor).

Step 2: Enter the Formula

Type the formula =A1/B1*100 into a new cell, replacing A1 and B1 with the references of the cells you’re calculating the percentage for.

This formula divides the value in cell A1 by the value in cell B1 and then multiplies the result by 100 to give you a percentage. It’s the multiplication by 100 that converts the decimal into a percentage, as the result of division would otherwise be a decimal less than 1.

Step 3: Press Enter and Format the Cell

After typing the formula, press Enter to calculate the percentage. Then, select the cell and format it as a percentage if needed.

Once you press Enter, the calculated percentage will appear in the cell. If it doesn’t automatically format with the percentage symbol, you can right-click on the cell, choose ‘Format Cells,’ and then select ‘Percentage’ to display it correctly.


Ease of UseMicrosoft Excel’s formula feature makes calculating percentages straightforward, requiring just a basic understanding of division and multiplication.
AccuracyBy using Excel to find percentages, you reduce the risk of manual calculation errors.
VersatilityExcel’s percentage calculations can be applied to a wide range of data analysis tasks across various industries.


Learning CurveSome users may find Excel formulas intimidating, leading to a learning curve for those less familiar with the program.
Over-reliance on FormulasRelying too heavily on formulas can lead to mistakes if the wrong cell references are used or if the formula is copied incorrectly.
Data Formatting IssuesIf cells aren’t properly formatted, Excel may not recognize values as numbers, which can lead to incorrect percentage calculations.

Additional Information

When using Excel to find the percentage of two cells, there are a few additional tips to consider. Remember that Excel uses a specific order of operations, following the PEMDAS rule (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). If your calculation is more complex, including other operations, you might need to use parentheses to ensure the correct order.

Another useful tip is to use absolute cell references (by adding a dollar sign before the column letter and row number, like $A$1) if you plan to copy the formula across multiple cells. This keeps the reference constant and prevents it from changing as you drag the formula across the spreadsheet.

Lastly, keep in mind that you can always use Excel’s built-in ‘Percentage’ format to instantly convert decimal numbers to percentages without needing to multiply by 100 in your formula.


  1. Identify the two cells for the percentage calculation.
  2. Enter the formula =A1/B1*100 into a new cell.
  3. Press Enter to calculate and format the result as a percentage if needed.

Frequently Asked Questions

What if the result shows as a decimal and not a percentage?

Simply format the cell where your result is displayed. Right-click on the cell, select ‘Format Cells,’ and then choose ‘Percentage’ to see the result as a percentage.

Can I use this method to calculate the percentage difference between two cells?

Yes, you can. Instead of dividing one cell by the other, subtract one from the other, divide by the original number, and then multiply by 100.

What do I do if I get a #DIV/0! error?

This error occurs when you’re trying to divide by zero. Make sure that the cell being used as the divisor (denominator) has a number other than zero in it.

How can I show more or fewer decimal places in the percentage result?

After formatting the cell as a percentage, you can increase or decrease the number of decimal places using the ‘Increase Decimal’ or ‘Decrease Decimal’ buttons on the Home tab.

Can I use this percentage calculation in charts or graphs?

Absolutely! Once you have the percentage calculated in a cell, you can use that cell as a data point in various charts and graphs within Excel.


Mastering how to find the percentage of two cells in Microsoft Excel is a valuable skill that can streamline your data analysis and enhance your decision-making processes. Whether you are a student, business professional, or casual Excel user, understanding percentages is crucial for interpreting data meaningfully.

With the easy-to-follow steps outlined in this article, and the additional insights provided, you’re well-equipped to use percentages in Excel to your advantage. Remember, Excel is more than just a spreadsheet tool; it’s a gateway to unlocking the stories hidden within your data.
