Understanding basic percentage calculation
In Excel, calculating percentages is a common task for various purposes such as analyzing data, creating reports, and making financial projections. Understanding the basics of percentage calculation in Excel is essential for utilizing this powerful tool to its full potential.
A. Explaining the concept of percentage in Excel Percentage is a way of expressing a fraction or a ratio as a whole number out of 100.
 In Excel, percentages are commonly used to compare values, track changes, and calculate growth rates.
B. Showing examples of basic percentage calculations using formulas
 To calculate a percentage in Excel, you can use the formula:
= (part / total) * 100
.  For instance, if you want to calculate the percentage of a specific value (part) in relation to a total value, you can input the formula in a cell and replace "part" and "total" with the respective cell references.
 Excel also provides builtin functions such as
=PERCENTAGE()
and=PERCENTRANK()
for performing percentage calculations.
Calculating percentage change
When working with data in Excel, it's often important to calculate percentage change in order to analyze trends or compare values. Understanding how to calculate percentage change in Excel is a valuable skill for anyone working with spreadsheets.
Explaining the concept of percentage change and its importance
The percentage change is a measure of the difference between two values as a percentage of the original value. It is commonly used in business and finance to analyze changes in variables such as sales, revenue, or expenses. Calculating percentage change allows you to see the relative increase or decrease in a value over time or in comparison to another value.
Providing examples of how to calculate percentage change in Excel
There are a few different methods for calculating percentage change in Excel, depending on the specific scenario. Here are a couple of common examples:

Simple percentage change: To calculate the percentage change between two values, you can use the formula:
((New Value  Old Value) / Old Value) * 100
. This will give you the percentage increase or decrease between the two values. 
Percentage change over time: If you want to calculate the percentage change over multiple periods, such as months or years, you can use the formula:
((New Value  Old Value) / Old Value) ^ (1 / Number of Periods)  1
. This will give you the average percentage change per period.
By using these formulas in Excel, you can easily calculate percentage change and gain valuable insights from your data.
Excel Tutorial: How to calculate percentage in excel spreadsheet
Calculating percentages in Excel is a common task for many users. Fortunately, Excel provides builtin functions to make this process fast and accurate. In this tutorial, we will introduce these functions and demonstrate how to use them with examples.
A. Introducing the builtin functions for percentage calculation in ExcelExcel offers several builtin functions for calculating percentages. These include:
 PERCENTAGE: This function calculates the percentage of a number.
 PERCENTILE: This function returns the kth percentile of values in a range.
 PERCENTRANK: This function returns the rank of a value in a data set as a percentage of the data set.
 PERMUT: This function returns the number of permutations for a given number of objects.
 COMBIN: This function returns the number of combinations for a given number of items.
B. Demonstrating how to use these functions with examples
Now let's take a look at how to use these functions with examples.
1. Percentage Function (PERCENTAGE)
The PERCENTAGE function calculates the percentage of a number. For example, if you want to find 15% of 200, you can use the formula =PERCENTAGE(15, 200), which will return 30.
2. Percentile Function (PERCENTILE)
The PERCENTILE function returns the kth percentile of values in a range. For example, if you have a set of data in cells A1:A10 and you want to find the 75th percentile, you can use the formula =PERCENTILE(A1:A10, 75).
3. Percentrank Function (PERCENTRANK)
The PERCENTRANK function returns the rank of a value in a data set as a percentage of the data set. For example, if you have a set of data in cells A1:A10 and you want to find the percent rank of the value in cell A11, you can use the formula =PERCENTRANK(A1:A10, A11).
4. Permut and Combin Functions (PERMUT and COMBIN)
The PERMUT and COMBIN functions are used to calculate permutations and combinations, respectively. For example, if you want to find the number of permutations of 5 items taken 3 at a time, you can use the formula =PERMUT(5, 3).
Formatting cells for percentage display
When working with Excel spreadsheets, it's important to be able to display percentages accurately. Fortunately, Excel provides several options for formatting cells to display percentages.
Explaining the different options for formatting cells to display percentages
 Standard Percentage Format: This option displays percentages with two decimal places, and the % symbol. It is the most common way to display percentages in Excel.
 Custom Percentage Format: This option allows users to customize the display of percentages by specifying the number of decimal places, the use of commas, and the positioning of the % symbol.
 Accounting Percentage Format: This option is similar to the standard percentage format, but it aligns the % symbol with the currency symbol for a cleaner look.
