Calculating the **average percentage** may appear to be an uncomplicated task. But it is not like the average where the total value is divided by the number of values. For that reason, sophisticated and authentic methods are essential. Today, in this article, I will discuss **three **suitable methods to **calculate average percentage in Excel **effectively with appropriate illustrations.

## Percentage Basics

The word **‘percent’ **refers to **‘for hundreds each’** and it is also expressed as the **%** symbol. A **percentage **is a quantity or ratio that is a fraction of 100. Divide the number by the whole number and **multiply by 100** if we need to **calculate the percent of a number**. But the word **‘percentage’ **also means “to be a part of a whole,” which can be expressed in hundredths.

The **difference between percentage** and percent isn’t clear to many of us. That’s why we often use these two words interchangeably. Generally, the percent encloses a specific number, whereas the percentage refers to the change between numbers.

## Average Basics

In a set of numbers, the average value is the value, calculated by dividing the total by the number of numbers. For instance, the average of 5, 6, 8, 10, and 11 will be 8 where the sum of total values is 5+6+8+10+11=40 and the number of values is 5. To express a basic **Average Formula**, we can write,

`Average = (Sum of numbers of a set) / (Total numbers in that set)`

## Introduction to Average Percentages

The average percentage is basically the mean value of percentages. The number of percentages may be two or even more, it actually depends on the dataset. For example, in an educational institution, the preference for sports in the case of teachers is **40%** whereas in the case of students it is **80%**. Now, what will be the average percentage? Actually, it is **64%** and it will be discussed in this article how this percentage is calculated.

## Common Mistakes While Calculating Average Percentage

Usually, we use the **AVERAGE** formula of **MS Excel **to determine the average of any quantities. If we calculate the average percentage in such a way, it will undoubtedly be wrong. So, be careful and avoid this mistake. As shown in the following figure, the average percentage is determined in cell **D8 **using the **AVERAGE** formula, though it is not correct.

## 3 Suitable Ways to Calculate Average Percentage in Excel

The average percentage can be calculated using the following **three **methods. Whatever the methods, the output will be the same. To calculate average percentages, we will use the **SUMPRODUCT**, **SUM****, **and **AVERAGE** functions and **Mathematical **formulas. Here’s an overview of the dataset for today’s task.

### 1. Combine SUMPRODUCT and SUM Functions to Calculate Average Percentage

In this section, we will apply the **SUMPRODUCT** and **SUM** functions to calculate average percentages in **Excel**. From our dataset, we can easily do that. Let’s follow the instructions below to learn!

**Steps:**

- First of all, select cell
**D7**and write down the below**SUMPRODUCT**and**SUM**functions in that cell. The functions are,

`=SUMPRODUCT(C5:C6,D5:D6)/SUM(C5:C6)`

- Hence, simply press
**Enter**on your keyboard. As a result, you will get an average percentage which is the return of**the SUMPRODUCT and SUM functions**. The return is**0.64.**

- Now, we will convert the fraction into a percentage. To do that, firstly select cell
**D7**. Hence, from your**Home**tab, go to,

**Home → Number → Percentage**

- As a result, you will be able to calculate
**average percentages**which have been given in the below screenshot.

### 2. Calculating Average Percentage by Using Data from A Survey

In the following dataset, we see that the number of participants surveyed and preference for sports in percentage are given. We have to find out the average percentage of preference for sports. It’s astonishing that we can determine our expected value simply if we proceed with the following steps. The steps are as follows:

**Step 1: Determine the number that each percentage of preference denotes**

- First of all, select cell
**E5,**and write down the below**Mathematical**formula in that cell. The**Mathematical**formula is,

`=C5*D5`

- Now, press
**Enter**on your keyboard. As a result, you will get the return of the**Mathematical**The return is**320**.

- Hence,
**AutoFill**the**Mathematical**formula to the rest of the cells in column**E**.

**Note: **You can do the same thing by converting the percentage into a decimal. For this, you have to proceed with the following steps-

- Select cells
**D5**to**D6**. Presson your keyboard.**Ctrl + 1**

- As a result, a
**Format Cells**window pops up. From the**Format Cells**window, firstly, choose the**Number**Secondly, select the**General**option under the**Category**drop-down list. At last, press the**OK**option.

- The result will remain unchanged.

**Step 2: Find the Total Value**

- In this situation, you have to use
**the SUM function**of excel to determine the total number of participants.

`=SUM(C5:C6)`

- Hence, press
**Enter**on your keyboard. As a result, you will get the return of the**SUM function**. The return is**2000**.

- Similarly, apply
**the SUM function**to calculate the total number of preferences like the following.

`=SUM(E5:E6)`

- Further, press
**Enter**on your keyboard. As a result, you will get the return of the**SUM function**. The return is**1280**.

**Step 3: Determine the Average Percentage**

- Chose the cell After that, write down
**the SUM function**in that cell.**The SUM function**is,

`=E7/C7`

- Hence, press
**Enter**on your keyboard, and you will get an average percentage. The average percentage is**64%.**

### 3. Utilizing a Defined Formula to Calculate Average Percentage

In the following figure, we see a dataset of the given sample size and percentage. Now you have to calculate the average percentage.

The formula for the average percentage is:

`(((Percentage1*number1)+(percentage2*number2))/total number))*100`

Here the **Teachers **are **Number 1** and the **Students **are **Number 2**. The percentages are also respectively given. The Total Number is the combined number of **Teachers **and **Students**.

Then you may proceed with the following steps to learn!

**Steps:**

- First of all, select cell
**D8**, and write down the below formula,

`=(C5*D5+C6*D6)/C7`

- Hence, press
**Enter**on your keyboard. As a result, you will get the return of the**average percentage**into fractions. The fraction is**0.64**.

- Now, we will convert the fraction into a percentage. To do that, press
on your keyboard.**Ctrl + Shift + %**

- As a result, you will be able to convert fractions into percentages. The average percentage is
**64%.**

## Calculate Average Percentage of Marks in Excel

The **AVERAGE function** is categorized under** the Statistical functions** in Excel. This function returns the average value of a given argument. From the description of the **AVERAGE** function, you might have understood that the basic use of this function is to find the **average** of several numbers in an **Excel** Sheet.

To show examples, we have brought a simple dataset of six students and their respective scores in three tests. For this, you need to **insert** an **extra column** of **Average** before the **Average Percentage** column. Let’s follow the instructions below to learn!

**Steps:**

- First, we have to select
**cell F5**. After that, write down the below**AVERAGE**function in that cell. The function is,

`=AVERAGE(C5:E5)`

- Hence, simply press
**Enter**on your keyboard. As a result, you will get an average percentage which is the return of**the AVERAGE function**. The return is**77.6666667.**

- Hence,
**AutoFill**the**AVERAGE**function to the rest of the cells in column**F**.

- Again, write down the below formula in cell
**G5**.

`=F5/100`

- Hence, press
**Enter**on your keyboard, and you will get the output of the formula. The output is**0.78**. - Here,
**F5/100**will show the**average percentage of marks**in fraction form.

- Hence,
**AutoFill**the**Mathematical**formula to the rest of the cells in column**G**.

- Now, we will convert the fraction into a percentage. To do that, press
**Ctrl + Shift + %**on your keyboard.

- As a result, you will be able to convert fractions into percentages which have been given in the below screenshot.
