## Understanding the basic formula

In this section, we will explore the basic formula for calculating percent increase in Excel and provide an example to illustrate the process.

**A. Explaining the basic formula for calculating percent increase**

The basic formula for calculating percent increase in Excel is:

**((New Value - Old Value) / Old Value) * 100**

This formula calculates the difference between the new and old values, divides it by the old value, and then multiplies by 100 to express the result as a percentage increase.

**B. Providing an example to illustrate the formula**

Let's use the following example to illustrate the formula:

- Old Value: 100
- New Value: 150

Using the formula, we can calculate the percent increase as follows:

**((150 - 100) / 100) * 100 = 50%**

So, the percent increase from the old value of 100 to the new value of 150 is 50%.

## Excel Tutorial: How to calculate percent increase in Excel

Calculating percent increase in Excel is a common task for many professionals. Whether you're analyzing sales data, financial trends, or any other numerical information, knowing how to calculate percent increase can be a valuable skill. In this tutorial, we'll walk you through the steps of applying the formula in Excel.

### Applying the formula in Excel

**A. Step-by-step guide on how to input the formula in Excel**

- Start by selecting the cell where you want the result to appear.
- Input the following formula:
`=((New Value - Old Value) / Old Value) * 100`

- Replace "New Value" with the reference to the cell containing the new value.
- Replace "Old Value" with the reference to the cell containing the old value.
- Press Enter to apply the formula and calculate the percent increase.

**B. Using cell references in the formula**

- Using cell references in the formula allows you to easily update the values without having to rewrite the formula.
- For example, if you have the new value in cell A1 and the old value in cell B1, the formula would be:
`=((A1 - B1) / B1) * 100`

- When the values in cells A1 and B1 are updated, the percent increase will automatically recalculate.

## Utilizing functions for percent increase calculation

When working with data in Excel, it is often necessary to calculate the percent increase between two values. Fortunately, Excel offers a built-in function that makes this calculation quick and easy. In this tutorial, we will explore how to use the 'Percentage Increase' function in Excel to calculate percent increase.

**A. Introducing the 'Percentage Increase' function in Excel**

The 'Percentage Increase' function in Excel is a straightforward way to calculate the percentage increase between two numbers. The formula for the function is as follows:

`=((new_value - old_value) / old_value) * 100`

Where **new_value** is the new value, and **old_value** is the original value.

**B. Demonstrating how to use the function with examples**

Let's walk through a couple of examples to illustrate how the 'Percentage Increase' function works.

### Example 1:

- Old value: 100
- New value: 150

To calculate the percent increase, we can use the 'Percentage Increase' function:

`=((150 - 100) / 100) * 100`

When we plug in the values, we get:

`=(50 / 100) * 100`

Which simplifies to:

`=50%`

So, the percent increase between 100 and 150 is 50%.

### Example 2:

- Old value: 75
- New value: 100

Using the 'Percentage Increase' function:

`=((100 - 75) / 75) * 100`

Plugging in the values:

`=(25 / 75) * 100`

Simplifying, we get:

`=33.33%`

So, the percent increase between 75 and 100 is approximately 33.33%.

As demonstrated by these examples, the 'Percentage Increase' function in Excel provides a quick and efficient way to calculate percent increase between two values.

## Formatting the Result

After calculating the percent increase in Excel, it's important to format the result in a clear and effective manner.

### Tips for Formatting the Percent Increase Result in Excel

- Use the "Percentage" number format to display the result as a percentage.
- Avoid using too many decimal places to keep the result clean and easy to read.
- Consider using a different font, color, or border to highlight the result and make it stand out within the spreadsheet.

### Using Custom Number Formats to Display the Result Effectively

Excel allows users to create custom number formats to display data in unique ways. This can be particularly useful when presenting percent increase results.

- Utilize the "Custom" option in the Number Format menu to create a format specifically for percent increase results.
- Consider including text or symbols alongside the percentage to provide additional context or clarity.
- Experiment with different formatting options to find a style that best suits the overall presentation of the data.

## Common errors to avoid

When calculating percent increase in Excel, it's important to be aware of the common errors that can occur. By identifying these mistakes and providing solutions to avoid them, you can ensure accurate calculations and reliable data.

**A. Identifying common mistakes when calculating percent increase**

- Not using the correct formula: One common mistake is using the wrong formula to calculate percent increase. This can lead to inaccurate results and misinterpretation of data.
- Ignoring the order of operations: Another mistake is failing to follow the correct order of operations when calculating percent increase, which can result in errors in the final percentage.
- Not converting decimal to percentage: Failing to convert the decimal result to a percentage is another common mistake, which can lead to incorrect representation of the percent increase.

**B. Providing solutions to avoid these errors**

- Use the correct formula: To avoid using the wrong formula, make sure to use the formula for percent increase, which is ((new value - old value) / old value) * 100.
- Follow the order of operations: It's important to follow the correct order of operations when calculating percent increase, which involves performing the subtraction before the division and multiplication.
- Convert decimal to percentage: After calculating the percent increase, always remember to convert the decimal result to a percentage by multiplying by 100 and adding the percentage symbol (%).
