# How to Increase a Number by a Percentage in Excel?

Are you struggling with calculating a number by a percentage in Excel? If so, you’re not alone. Many people struggle with this task, but it’s easier than you think! In this guide, we’ll show you how to increase a number by a percentage in Excel and provide you with a few tips to make the process even simpler. So, if you’re ready to learn how to calculate a number by a percentage in Excel, let’s get started!

## Understanding the Basics of Increasing a Number by a Percentage in Excel

Increasing a number by a percentage in Microsoft Excel is a simple task. It involves using the formula =number+(number*percentage). This formula multiplies the number by the percentage and adds the result to the original number. This can be used to calculate sales taxes, interest rates, or any other calculation that requires a percentage increase.

To use this formula in Excel, you need to have the original number and the percentage ready. The percentage should be expressed in decimal form, with a value between 0 and 1. For example, if you want to increase a number by 10%, the percentage should be expressed as 0.10. Once you have the required data, you can enter the formula into a cell in Excel.

### Entering the Formula into Excel

To enter the formula into Excel, simply type =number+(number*percentage) into the desired cell. Replace “number” with the original number and “percentage” with the decimal representation of the percentage. If you are increasing the number by 10%, the formula should look like this: =B2+(B2*0.10).

After entering the formula, press enter to calculate the result. The cell will display the result of the formula, which is the new number after the percentage increase. You can then use this number in other calculations or to display the final result.

### Tips for Using the Formula

When entering the formula into Excel, it is important to use the correct syntax. Make sure that the original number and the percentage are separated by parentheses and that the percentage is expressed as a decimal. If the formula is not entered correctly, the result will be incorrect.

If you need to increase a number by a percentage multiple times, you can use the same formula with different numbers. This is especially useful if you need to calculate sales taxes or other fees that are applied multiple times.

If you don’t want to manually enter the formula each time, you can use a pre-formatted spreadsheet. Microsoft Excel comes with several pre-formatted spreadsheets that can be used to calculate the percentage increase. These spreadsheets contain the formula already entered, so you just need to enter the original number and the percentage.

### Using Other Formulas

In addition to the formula =number+(number*percentage), there are several other formulas that can be used to calculate the percentage increase. These formulas include the basic percentage calculation formula (percentage of number=number*percentage) and the percentage increase formula (percentage increase=final number-original number). While these formulas may be more complicated than the standard formula, they can be useful if you need to calculate the percentage increase for multiple numbers.

### Creating a Custom Function

If you need to use the percentage increase calculation frequently, you can create a custom function in Microsoft Excel. This function can be used to quickly calculate the percentage increase for multiple numbers. To create the function, open the Visual Basic Editor and enter the following code:

#### Function IncreaseByPercentage(originalNumber As Double, percentage As Double) As Double

IncreaseByPercentage = originalNumber + (originalNumber * percentage)

End Function

Once the code is entered, save the file and close the Visual Basic Editor. The custom function can then be used in Excel just like any other formula.

## Top 6 Frequently Asked Questions

### What is a Percentage?

A percentage is a way to express a number as a fraction of 100. It is often expressed as a whole number or a decimal, but is always out of 100. For example, 25% is the same as 0.25 and is equal to 25 out of 100.

### How do I Increase a Number by a Percentage in Excel?

To increase a number by a percentage in Excel, use the following formula: =Original Number + (Original Number x Percentage). For example, to increase the number 25 by 10%, you would use the formula =25+(25*10%). This would result in the number 27.5, which is an increase of 10% from the original number.

### What is the Difference Between Increasing and Decreasing a Number by a Percentage?

The difference between increasing and decreasing a number by a percentage is the sign used in the formula. To increase a number by a percentage, you use the plus sign (+) in the formula. To decrease a number by a percentage, you use the minus sign (-) in the formula.

### What is the Formula for Decreasing a Number by a Percentage in Excel?

To decrease a number by a percentage in Excel, use the following formula: =Original Number – (Original Number x Percentage). For example, to decrease the number 25 by 10%, you would use the formula =25-(25*10%). This would result in the number 22.5, which is a decrease of 10% from the original number.

### What is the Formula for Increasing or Decreasing a Number by More than One Percentage in Excel?

To increase or decrease a number by more than one percentage in Excel, you can use the same formulas as mentioned above. However, rather than inserting a single percentage into the formula, you would insert a range of percentages. For example, if you wanted to increase the number 25 by 10%, 20%, and 30%, you would use the formula =25+(25*10%)+(25*20%)+(25*30%).

### What is the Formula for Finding the Percentage Increase or Decrease Between Two Numbers in Excel?

To find the percentage increase or decrease between two numbers in Excel, use the following formula: =(New Number – Original Number)/Original Number. For example, if the original number is 25 and the new number is 27.5, you would use the formula =(27.5-25)/25. This would result in 0.1, which is equal to a 10% increase.

Excel is an incredibly powerful tool that can help you increase a number by a percentage quickly and easily. With the right formulas and a bit of practice, you can learn how to do this in no time. You’ll also be able to take advantage of Excel’s other features, such as charts and pivot tables, to make your data visualization tasks easier. With its powerful features and ease of use, Excel is the perfect tool for increasing numbers by a percentage.
