how to calculate a percentage increase in excel

Calculating percentage increase in Excel is a straightforward process. Here are 8 important points to remember:

• Use the formula: (New Value - Original Value) / Original Value x 100
• Enter values in adjacent cells
• Use cell references instead of values
• Format cells as percentages
• Check for errors
• Use built-in functions like PERCENTAGEINC
• Consider negative values
• Apply conditional formatting for visual representation

With these points in mind, you can confidently calculate percentage increase in Excel for various scenarios.

Use the formula: (New Value - Original Value) / Original Value x 100

At the heart of calculating percentage increase in Excel lies a simple yet powerful formula: (New Value - Original Value) / Original Value x 100.

Let's break down each part of the formula:

• New Value: This is the final value or the value after the change.
• Original Value: This is the initial value or the value before the change.
• Percentage Increase: This is the result of the formula, which represents the percentage change between the new value and the original value. It should be expressed as a percentage, hence the multiplication by 100.

To use this formula in Excel, follow these steps:

1. Enter the new value and the original value in adjacent cells.
2. In a separate cell, type the formula: =(New Value Cell - Original Value Cell) / Original Value Cell x 100
3. Press Enter to calculate the percentage increase.
4. Format the cell as a percentage by clicking the Percentage Style button in the Number group on the Home tab.

For example, if the new value is 120 and the original value is 100, the percentage increase would be calculated as: (120 - 100) / 100 x 100 = 20%.

Remember to check for errors and ensure that you are using the correct values and cell references in the formula. Negative values should also be considered, as they can result in negative percentage increases.

Enter values in adjacent cells

When calculating percentage increase in Excel, it's important to enter the new value and the original value in adjacent cells. This makes it easier to reference the values in the formula and avoid errors.

Adjacent cells are cells that are next to each other, either horizontally or vertically. For example, cells A1 and B1 are adjacent horizontally, while cells A1 and A2 are adjacent vertically.

To enter values in adjacent cells:

1. Click on the cell where you want to enter the new value.
2. Type the new value and press Enter.
3. Click on the adjacent cell where you want to enter the original value.
4. Type the original value and press Enter.

Once you have entered the values in adjacent cells, you can use the formula =(New Value Cell - Original Value Cell) / Original Value Cell x 100 to calculate the percentage increase.

For example, if you enter the new value in cell B2 and the original value in cell B3, the formula would be: =(B2 - B3) / B3 x 100.

By entering the values in adjacent cells, you can easily reference them in the formula and ensure that the calculation is accurate.

Remember to double-check the values and cell references in the formula to avoid any errors. You can also use cell formatting to highlight the cells containing the new value, original value, and percentage increase for clarity.

Use cell references instead of values

Instead of typing the new value and original value directly into the formula, it's better practice to use cell references. Cell references are the addresses of cells, such as A1, B2, or C3. Using cell references makes the formula more flexible and easier to edit.

To use cell references in the percentage increase formula:

1. Enter the new value and original value in adjacent cells.
2. In a separate cell, type the formula =(New Value Cell - Original Value Cell) / Original Value Cell x 100.
3. Replace the "New Value Cell" and "Original Value Cell" with the actual cell references. For example, if the new value is in cell B2 and the original value is in cell B3, the formula would be: =(B2 - B3) / B3 x 100.
4. Press Enter to calculate the percentage increase.

Using cell references has several advantages:

• Flexibility: If you need to change the values, you can simply update the values in the referenced cells, and the formula will automatically recalculate the percentage increase.
• Error reduction: By using cell references, you eliminate the risk of typos and errors when entering the values directly into the formula.
• Formula auditing: It's easier to audit and understand the formula when you can see the cell references instead of hard-coded values.

As a general rule, it's always better to use cell references instead of values in formulas, as it makes your spreadsheets more dynamic, error-free, and easier to maintain.

Format cells as percentages

To display the percentage increase correctly, it's important to format the cell as a percentage. This will add the percentage symbol (%) to the value and ensure that it's interpreted as a percentage.

• Select the cell containing the percentage increase value.

Click on the cell where the percentage increase is calculated.

Locate the Number group on the ribbon, which typically appears at the top of the Excel window.

Look for the button with a percent sign (%) in the Number group. It's usually located next to the Currency Style and Comma Style buttons.

You can also press Ctrl + Shift + %. This keyboard shortcut applies the percentage format to the selected cell.

Once you apply the percentage format, the value in the cell will be displayed with the percentage symbol. This makes it easier to read and understand the percentage increase.

Check for errors

It's crucial to check for errors when calculating percentage increase in Excel to ensure accurate results. Here are some common errors to watch out for:

• Incorrect formula:

Make sure you have entered the formula correctly. Check for typos, missing parentheses, or incorrect cell references.

Ensure that the new value and original value are valid numeric values. Avoid using text or blank cells in the calculation.

If the original value is zero, dividing by it will result in a #DIV/0! error. Make sure the original value is not zero before calculating the percentage increase.

Negative values can lead to unexpected results. Consider the context of your data and ensure that negative values are handled appropriately.

To check for errors, you can use Excel's error checking features. Go to the Formulas tab and click on the Error Checking button. This will highlight any cells containing errors, including those related to the percentage increase calculation.

Use built-in functions like PERCENTAGEINC

Excel provides a built-in function called PERCENTAGEINC that can be used to calculate percentage increase. This function simplifies the calculation and reduces the risk of errors.

• Syntax:

The syntax of the PERCENTAGEINC function is: =PERCENTAGEINC(new_value, original_value)

• new_value: The final value or the value after the change.
• original_value: The initial value or the value before the change.

To calculate the percentage increase from 100 to 120, you would use the formula: =PERCENTAGEINC(120, 100). This would return a result of 0.2, which represents a 20% increase.

• Simplicity: The PERCENTAGEINC function provides a concise and easy-to-use formula for calculating percentage increase.
• Accuracy: The function performs the calculation automatically, reducing the chances of errors.
• Consistency: Using a built-in function ensures consistency in calculations across different spreadsheets and users.

While the PERCENTAGEINC function is a convenient option, you can still use the manual formula (New Value - Original Value) / Original Value x 100 if you prefer.

Consider negative values

When calculating percentage increase, it's important to consider negative values. Negative values can arise in various scenarios, such as a decrease in sales, a drop in stock prices, or a reduction in expenses.

Negative values can affect the percentage increase calculation in the following ways:

• Positive percentage increase with negative original value: If the original value is negative and the new value is positive, the percentage increase will be positive. This indicates a recovery or improvement from a negative starting point.
• Negative percentage increase with positive original value: If the original value is positive and the new value is negative, the percentage increase will be negative. This represents a decline or decrease from a positive starting point.
• Negative percentage increase with negative original and new values: If both the original value and the new value are negative, the percentage increase will also be negative. This signifies a further decrease from an already negative starting point.

It's crucial to interpret the percentage increase in the context of your data and the business scenario. Negative percentage increases can indicate a decline or loss, while positive percentage increases represent growth or improvement.

To ensure accurate and meaningful results, always consider the possibility of negative values when calculating percentage increase in Excel. Handle negative values appropriately based on the specific context and the intended interpretation of the results.

Apply conditional formatting for visual representation

Conditional formatting is a powerful tool in Excel that allows you to apply different formatting styles to cells based on specific conditions. You can use conditional formatting to visually represent percentage increases in your data, making it easier to identify trends and outliers.

• Select the cells containing the percentage increase values.

Click and drag to select the range of cells that contain the percentage increase values you want to format.

Locate the Conditional Formatting button in the Styles group on the Home tab. It's typically represented by an icon of a colored box with a drop-down arrow.

From the drop-down menu, choose the conditional formatting rule that you want to apply. Here are a few common options:

• Color Scales: Applies a gradient of colors to the cells, with different colors representing different values of percentage increase.
• Data Bars: Adds colored bars to the cells, with the length of the bar indicating the magnitude of the percentage increase.
• Icon Sets: Assigns icons to the cells, such as arrows or symbols, to visually represent the direction and magnitude of the percentage increase.

Once you select a rule, a dialog box will appear. Here, you can adjust the rule settings to fine-tune the visual representation. For example, you can change the color scale, data bar colors, or icon set.

By applying conditional formatting, you can quickly identify cells with high or low percentage increases, track trends over time, and make your data more visually appealing and easier to understand.
