Remember, practice and experimentation are key to mastering percent increase calculations in Excel.
Understand the concept: Percent increase measures the change between two values.
At its core, percent increase is a mathematical calculation that measures the change between two values, typically expressed as a percentage. It quantifies the extent to which a value has increased or decreased over time or in comparison to another value.
In the context of Excel, calculating percent increase involves using a specific formula that compares two values and expresses the change as a percentage. The formula is: Percent Increase = ((New Value – Old Value) / Old Value) * 100
To understand this formula, break it down into its components:
 New Value: This is the most recent value or the value at the end of the period being measured.
 Old Value: This is the original value or the value at the beginning of the period being measured.
 Subtract (New Value – Old Value): This calculates the absolute change or difference between the two values.
 Divide by Old Value: This normalizes the change by dividing it by the old value, making the result independent of the magnitude of the old value.
 Multiply by 100: This converts the result from a decimal to a percentage.
By applying this formula, you can determine the percentage increase or decrease between any two values, providing a standardized and comparable measure of change.
Now that you understand the concept and formula, let’s move on to practical examples of calculating percent increase in Excel.
Formula: Use the formula “=(New Value – Old Value) / Old Value * 100” to calculate percent increase.
The formula for calculating percent increase in Excel is: Percent Increase = ((New Value – Old Value) / Old Value) * 100

New Value:
This is the most recent value or the value at the end of the period being measured. In Excel, this value can be a number, a cell reference, or a range of cells.

Old Value:
This is the original value or the value at the beginning of the period being measured. Similar to the new value, this can be a number, a cell reference, or a range of cells.

Subtract (New Value – Old Value):
This step calculates the absolute change or difference between the two values. The result is the amount by which the new value has increased or decreased compared to the old value.

Divide by Old Value:
This step normalizes the change by dividing it by the old value. This makes the result independent of the magnitude of the old value, allowing for meaningful comparisons between different values.

Multiply by 100:
Finally, the result is multiplied by 100 to convert it from a decimal to a percentage. This gives us the percent increase or decrease as a percentage value.
By following these steps and using the provided formula, you can accurately calculate the percent increase in Excel, making data analysis and comparison of values a breeze.
Relative vs. absolute: Specify if the percent increase is relative or absolute.
When calculating percent increase in Excel, it’s important to specify whether the percent increase is relative or absolute.

Relative Percent Increase:
Relative percent increase expresses the change as a percentage of the old value. It shows the proportional change between the two values. The formula for relative percent increase is: ((New Value – Old Value) / Old Value) * 100

Absolute Percent Increase:
Absolute percent increase expresses the change as a fixed amount, regardless of the old value. It shows the actual difference between the two values as a percentage. The formula for absolute percent increase is: (New Value – Old Value) * 100
The choice between relative and absolute percent increase depends on the context and the specific information you want to convey. Generally, relative percent increase is more useful when comparing values of different magnitudes, as it shows the proportional change. Absolute percent increase, on the other hand, is more appropriate when you want to know the actual difference between two values.
Format as percentage: Apply the percentage format to display the result as a percentage.
Once you have calculated the percent increase using the formula, it’s important to format the result as a percentage to make it readable and understandable. Here’s how to do it:

Select the Cell:
Select the cell containing the percent increase value that you want to format.

Open the Number Format Dialog Box:
Rightclick on the selected cell and choose “Format Cells” from the context menu. Alternatively, you can press “Ctrl + 1” to open the “Format Cells” dialog box.

Choose Percentage Format:
In the “Format Cells” dialog box, click on the “Percent” category under “Number.” This will apply the percent format to the selected cell.

Specify Decimal Places:
(Optional) If you want to display a specific number of decimal places in the percent increase, you can adjust the “Decimal places” field in the “Format Cells” dialog box.

Click “OK”:
Click “OK” to apply the percent format to the selected cell.
After following these steps, the percent increase value in the selected cell will be displayed as a percentage, making it easier to interpret and compare with other values.
Tip: You can also use the “Percent Style” button in the “Number” group on the Home tab of the Excel ribbon to quickly apply the percent format to a selected cell.
Handle negative values: Negative values indicate a decrease.
When calculating percent increase in Excel, it’s important to consider the possibility of negative values. Negative values indicate a decrease rather than an increase.

Interpreting Negative Percent Increase:
If the result of your percent increase calculation is a negative value, it means that there has been a decrease in the value. For example, a percent increase of 5% indicates a 5% decrease.

Absolute vs. Relative Interpretation:
Whether you interpret the negative percent increase as absolute or relative depends on the context. In the case of absolute percent increase, a negative value directly represents the amount of decrease. For relative percent increase, the negative value indicates the percentage decrease relative to the old value.

Using Absolute Value:
Sometimes, it’s useful to work with the absolute value of the percent increase, especially when you’re interested in the magnitude of the change without regard to the direction (increase or decrease). The absolute value of a negative percent increase is the positive value of the decrease.

Formatting Negative Percent Increase:
When formatting negative percent increase values, it’s common to enclose them in parentheses or add a minus sign () before the percentage to clearly indicate a decrease.
By understanding how to handle negative values in percent increase calculations, you can accurately interpret and communicate changes in data, whether they represent increases or decreases.
Use cell references: Reference cells instead of typing values for dynamic calculations.
To make your percent increase calculations dynamic and flexible, it’s recommended to use cell references instead of typing values directly into the formula.

Benefits of Using Cell References:
Using cell references offers several benefits:
 Easy Updates: If the underlying values change, the percent increase calculation will automatically update, saving you time and reducing errors.
 Dynamic Results: Cell references allow you to easily recalculate percent increase values based on changing data, making your spreadsheets more interactive and responsive.
 Error Reduction: By eliminating the need to manually enter values, you minimize the risk of errors and ensure the accuracy of your calculations.

How to Use Cell References:
To use cell references in your percent increase formula, simply enter the cell addresses of the new value and old value instead of the actual values. For example, if the new value is in cell B3 and the old value is in cell B2, your formula would be: =(B3 – B2) / B2 * 100

Relative vs. Absolute Cell References:
When using cell references, you can choose between relative and absolute references. Relative references adjust automatically when you copy or move the formula, while absolute references remain fixed to specific cells. Use absolute references when you want to ensure that the formula always refers to a specific cell, regardless of its location.

Mixed Cell References:
You can also use mixed cell references, where one part of the reference is absolute and the other is relative. This allows you to lock specific cells while maintaining the flexibility of relative references.
By incorporating cell references into your percent increase calculations, you can create dynamic and errorresistant spreadsheets that adapt to changing data and provide accurate results.
Apply conditional formatting: Use conditional formatting to highlight significant increases or decreases.
Conditional formatting is a powerful tool in Excel that allows you to visually highlight cells based on specific conditions. You can use conditional formatting to easily identify significant increases or decreases in your percent increase calculations.

Select the Data Range:
Select the range of cells containing the percent increase values that you want to format.

Open the Conditional Formatting Dialog Box:
Go to the “Home” tab in the Excel ribbon and click on the “Conditional Formatting” button. Alternatively, you can press “Ctrl + Shift + F” to quickly open the dialog box.

Create a New Rule:
In the “Conditional Formatting” dialog box, click on the “New Rule” button.

Choose a formatting style from the “Select a Rule Type” section. You can apply colors, font styles, borders, and more to highlight the cells.

Set the Formatting Conditions:
In the “Format cells that are” section, specify the condition that will trigger the formatting. For example, you can choose to highlight cells that are greater than or equal to a certain percentage increase or less than or equal to a certain percentage decrease.

Click “OK”:
Click “OK” to apply the conditional formatting rule to the selected cells.
Once you have applied conditional formatting, the cells that meet the specified conditions will be automatically highlighted, making it easy to identify significant increases or decreases in your data at a glance.
Tip: You can create multiple conditional formatting rules to highlight different levels of increases or decreases, allowing you to easily categorize and analyze your data.
Create charts and graphs: Visualize percent increase trends using charts and graphs.
Visualizing percent increase trends using charts and graphs can be a powerful way to communicate data and insights. Excel offers a variety of chart types that can be used to effectively display percent increase information.
