## Understanding the basic formula for percentage increase

When working with data in Excel, it is often necessary to calculate the percentage increase between two values. Understanding the basic formula for calculating percentage increase is essential for performing this task accurately.

A. Define the basic formula for calculating percentage increase

The basic formula for calculating percentage increase in Excel is:

Percentage Increase = ((New Value - Old Value) / Old Value) * 100

B. Provide an example to illustrate the formula

Let's say we want to calculate the percentage increase in sales from January to February. The sales in January were \$10,000 and in February they were \$12,000. Using the formula, we can calculate the percentage increase as follows:

Percentage Increase = ((\$12,000 - \$10,000) / \$10,000) * 100 = (2000 / 10000) * 100 = 0.20 * 100 = 20%

## Using Excel's built-in functions for percentage increase

Calculating percentage increase in Excel can be easily done using built-in functions. These functions allow users to quickly and accurately determine the percentage increase between two values. Below are the specific Excel functions that can be used for this purpose, as well as step-by-step instructions on how to use them.

### Introduce the specific Excel functions that can be used for calculating percentage increase

Excel offers several functions that can be used to calculate percentage increase. These include:

• Percentage Increase: This function is straightforward and calculates the percentage increase between two values.
• IF and ISERROR: These functions can be used in combination to handle any potential errors in the data and ensure accurate calculations.

### Provide step-by-step instructions on how to use these functions

Below are step-by-step instructions on how to use the Percentage Increase function in Excel:

1. Select the cell where you want the result to appear: This is the cell where the percentage increase will be displayed.

3. Press Enter: After entering the formula, press Enter to calculate the percentage increase.

Using the IF and ISERROR functions:

1. Use the IF function to handle potential errors: If there are any potential errors in the data, use the IF function in conjunction with the ISERROR function to handle them appropriately.
2. Enter the formula: In the selected cell, enter a formula that uses the IF and ISERROR functions to account for any errors and calculate the percentage increase accurately.

By following these steps and using the specific Excel functions outlined above, users can easily calculate percentage increase in Excel with precision and efficiency.

## Formatting the cells for percentage increase calculation

When it comes to calculating percentage increase in Excel, formatting the cells properly is crucial for accurate results. Without the correct cell formatting, your calculations can be misleading and inaccurate. In this chapter, we will discuss the importance of formatting cells for percentage increase calculations and provide some tips and tricks for effective cell formatting.

### Explain the importance of formatting cells properly for accurate percentage increase calculations

Proper cell formatting is essential for accurate percentage increase calculations because it ensures that the data is presented in the correct format for the calculation. If the cells are not formatted correctly, Excel may interpret the data incorrectly and produce inaccurate results. For example, if you are calculating percentage increase based on currency values, it is important to format the cells as currency to ensure the calculation reflects the correct monetary values.

### Provide tips and tricks for formatting cells effectively

• Use the "Percentage" format: When calculating percentage increase, it is important to format the cells as percentages. This can be done by selecting the cells, right-clicking, and choosing "Format Cells." Then, select "Percentage" from the list of number formats.
• Adjust decimal places: Depending on your preference, you may want to adjust the number of decimal places displayed for percentages. This can be done in the "Format Cells" menu by selecting the desired number of decimal places.
• Apply consistent formatting: For a professional and organized look, it is important to apply consistent formatting throughout your spreadsheet. This includes using the same number format for all cells containing percentage increase calculations.
