Excel Tutorial: How to Calculate Percentage Between Two Numbers in Excel


In today's tutorial, we will be discussing how to calculate percentages between two numbers in Excel using simple formulas. This is a fundamental skill for anyone working with data and can be applied to a wide range of tasks, from budgeting to analyzing trends.

Introduction to basic percentage formulas in Excel


Before we dive into the specific formulas, it's important to understand some basic concepts related to percentages in Excel. In Excel, percentages are typically represented as decimal values, where 1 equals 100%. This means that to calculate a percentage, you will often need to divide the percentage value by 100.

  • Percentage formula: The basic formula for calculating a percentage in Excel is: = (Part/Total) * 100. This formula can be used to find the percentage of a total value represented by a specific part.
  • Percentage as a fraction: In Excel, percentages can also be expressed as fractions, where 100% is equivalent to the fraction 1/1.

Step-by-step guide on how to use the 'percentage' formula


Now that we understand the basic concepts, let's walk through the steps to use the 'percentage' formula in Excel.

  • Step 1: Begin by entering the value of the part and the total in separate cells in your Excel worksheet.
  • Step 2: Select the cell where you want the percentage to appear and input the following formula: = (Part/Total) * 100
  • Step 3: Press 'Enter', and Excel will calculate the percentage based on the input values.

Explanation of the 'percentage difference' formula


In addition to calculating the percentage of a total value, you may also need to calculate the percentage difference between two numbers. This can be useful for analyzing changes over time or comparing data sets.

  • Percentage difference formula: The formula for calculating the percentage difference in Excel is: = ((New Value - Old Value) / Old Value) * 100. This formula will give you the percentage change between two values.
  • Visualizing percentage difference: To easily visualize the percentage difference, you can use a line chart in Excel to plot the changes over time or between different data sets.

Applying percentage calculation to a data set


When working with data in Excel, calculating percentages between two numbers is a common task. Whether you're analyzing financial data, sales figures, or any other type of numerical data, being able to calculate percentage change is essential.

A. Example data set for practice

Let's start with a simple example data set to practice calculating percentage change. Consider a data set with two columns: "Previous Value" and "Current Value."

  • Previous Value: 500
  • Current Value: 700

B. Walkthrough of how to calculate percentage change between two numbers in the data set

To calculate the percentage change between the previous value and the current value, follow these steps:

  1. Subtract the previous value from the current value: 700 - 500 = 200.
  2. Divide the result by the absolute value of the previous value: 200 ÷ 500 = 0.4.
  3. Multiply the result by 100 to get the percentage change: 0.4 x 100 = 40%.
C. Additional tips for applying percentage calculations to different types of data

When working with different types of data, it's important to consider the context of the data and the specific calculation needed. Here are some additional tips for applying percentage calculations:

  • Percentage of total: To calculate the percentage of a specific value in relation to the total, divide the value by the total and multiply by 100.
  • Year-over-year percentage change: When comparing data from different time periods, calculate the percentage change by subtracting the earlier value from the later value, dividing by the earlier value, and multiplying by 100.
  • Percentage difference: If you need to find the percentage difference between two numbers, calculate the absolute difference between the numbers, divide by the average of the numbers, and multiply by 100.


Formatting and presenting percentage calculations in Excel


When working with percentage calculations in Excel, it’s important to present the data in a clear and organized manner. This not only helps you understand the numbers better but also enables others to easily interpret the information. In this tutorial, we will discuss some tips for presenting percentage calculations, formatting cells to display percentages, and using conditional formatting for visual representation of percentage data.

Tips for presenting percentage calculations in a clear and organized manner


  • Use proper labels: Clearly label the percentage calculations to avoid any confusion. For example, if you’re calculating the percentage increase in sales, label the cell as “Percentage Increase” to make it clear for the reader.
  • Use consistent formatting: Ensure that all percentage calculations are presented in a consistent format throughout the document. This makes it easier to compare different sets of data.
  • Include additional context: Provide additional context or commentary alongside the percentage calculations to help the reader understand the significance of the numbers.

How to format cells to display percentages


Excel provides several options for formatting cells to display percentages. Here’s how you can do it:

  • Select the cell: Click on the cell where you want to display the percentage.
  • Go to the Home tab: Click on the “Home” tab in the Excel ribbon.
  • Click on the Percentage button: In the “Number” group, click on the “Percentage” button. This will format the cell to display the number as a percentage.

Using conditional formatting for visual representation of percentage data


Conditional formatting is a powerful tool in Excel that allows you to visually represent data based on certain conditions. Here’s how you can use conditional formatting for percentage data:

  • Select the cells: Select the range of cells containing the percentage data that you want to visually represent.
  • Go to the Home tab: Click on the “Home” tab in the Excel ribbon.
  • Click on Conditional Formatting: In the “Styles” group, click on “Conditional Formatting” and choose the type of visual representation you want, such as data bars, color scales, or icon sets.
