Today we will discuss another important topic on how to calculate the average percentage increase for marks in Excel formula. Here, we took an Excel sheet that represents ADAMâ€™s average percentage of marks in 5 different terms where each subject carries 100 marks. To represent the information Iâ€™ve taken 7 columns. These are Name, Terms, Physics, Chemistry, Mathematics, Avg. % (Average Percentage), and Avg. % Increase (Average Percentage Increase) respectively. We will calculate the average percentage increase from cell H6 to downward since we need a minimum of two percentage values to calculate the increase. Thatâ€™s why cell H5 is kept unoperated.

How to Calculate Average Percentage Increase for Marks in Excel Formula: 3 Easiest Ways

In this article, I will show you how to calculate the average percentage increase for marks using the Excel formula in 3 different and easiest ways.

1. Calculate Average Percentage Increase in Excel by Using Basic Formula Method

In this method, we will discuss the basic formula method to calculate the average percentage increase for marks in Excel.

• To start that method, we need to select cell H6 first.

• Now, we need to apply the following formula.
`=(G6-G5)/G5`
Formula Explanation
Here, G6-G5Â represents the difference between the two averages in Terms 1 and 2. Thatâ€™s why we need to divide it by G5 to calculate our desired average percentage increase.

• By clicking the ENTER button, we can find the increased value in fractions.
• Go to the Home tab >> Select % (Percentage) icon.

Immediately after selecting the % (Percentage) option from the Home tab, we can see there appears the average percentage increase in percentage form.

Here, we can see a negative percentage in cell H9, which means the average percentage decreases for marks in this Excel sheet.

2. Calculate Average Percentage Increase in Excel by Using Alternative Basic Formula Method

This one is all the same as the previous method. But here, we will use that formula in a different way and for this.

• We need to select cell H6.

• Now, we need to apply the following formula.
`=G6/G5-1`
Formula Explanation

Here, G6/G5 represents the respective average increase between Terms 1 and 2. Thatâ€™s why we need to subtract it by 1 to calculate our desired average percentage increase.

• Then, by clicking the ENTER button, we will find our desired increased value.

• After that, use Fill Handle to AutoFill the formula for the rest of the cells to get the average percentage increase of marks in Excel.

Eventually, we will be able to find the average percentage increase for all the Terms in this Excel sheet. Note that, why cell H9 represents the negative value is discussed earlier in the very first method of this article.

3. Calculate Average Percentage Increase in Excel by Using SUM Function

We can also calculate the average percentage increase in Excel by using the SUM function.

• We need to select cell H6.

• Now we need to apply the following formula.
`=SUM(G6-G5)/G5`
Formula Explanation

Here, SUM(G6-G5) represents the difference between the two averages in Terms 1 and 2. Thatâ€™s why we need to divide it by G5 to calculate our desired average percentage increase.

• Then, by clicking the ENTER button, we will find our desired increased value.

• After that, use Fill Handle to AutoFill the formula for the rest of the cells to get the average percentage increase of marks in Excel.

Eventually, we will be able to find the average percentage increase for all the Terms in this Excel sheet. Note that, why cell H9 represents the negative value is discussed earlier in the very first method of this article.
