Sometimes professors give more weight to a certain exam or quiz which means those exams contribute some value than other exams. In that case, the weighted percentage will come into account. Using these weighted percentages, the professors give the final result of a student. This article will show how to calculate the grades with weighted percentages in Excel. I think you find this really interesting and effective in the long run.

## Overview of Weighted Average

The weighted average is defined as the average where a weight is assigned to every quantity to show its importance. Using this weighted average, professors can **calculate the final grade** of a student with different weighted percentages. The Weighted average is more accurate than the normal average because it takes importance into account. The weighted average is the summation of the product of weights and quantities divided by the summation of the weights.

Letâ€™s consider some exams and their corresponding marks. Now, to get the final grade, you can use **the AVERAGE function**.

But the basic problem of this process is that it takes all the exams in a similar weight. In real life, it canâ€™t be possible because the final examâ€™s weight is higher than the quiz and assignment. In that case, the weighted average is much more accurate than the normal average. Letâ€™s assume, the assignment counts twice as much as a quiz and the final exam takes thrice as much as a quiz.

To calculate the weighted average, you need to apply the following formula.

In Excel, you can use **the SUMPRODUCT function** to calculate the product of weight and marks. Then use divide it by the summation of the weight by using **the SUM function**.

So, the weighted average takes the importance of each quantity and gives the final result which is far more accurate than the normal average. That is why the professors and teachers utilize the weighted average to calculate the final grade.

## 3 Easy Methods to Calculate Grades with Weighted Percentages in Excel

To calculate grades with the weighted percentages in Excel, we have found three different methods through which you can have a clear idea. In this article, we utilize the **SUMPRODUCT** function, **SUM** function, and the combination of **SUMPRODUCT** and **SUM** functions. All of these methods are fairly easy to understand. All of these methods give us the final grades with weighted percentages in Excel. We take a dataset that includes some exams and their corresponding weight.

### 1. Using SUMPRODUCT Function

Our first method is based on using** the SUMPRODUCT function**. When teachers take several exams or assignments, it is a must to have some weight in each exam or assignment. Because each exam is different from others in terms of importance. The final exam carries the highest importance so, the weight of the final exam is higher than any other exams or assignments. To use the **SUMPRODUCT** function, follow the steps carefully.

**Steps**

- First, merge the cells
**C14**and**D14**. - Then, select it and write down the following formula in the formula box.

`=SUMPRODUCT(C5:C13,D5:D13)`

**đź”Ž Breakdown of the Formula**

**SUMPRODUCT(C5:C13,D5:D13): **The **SUMPRODUCT** function multiplies the first element (**C5**) of the first array with the first element (**D5**) of the 2nd array. Then, it multiplies the 2nd element (**C6**) of the first array with the 2nd element (**D6**) of the 2nd array. Follow the same procedures until the array ends. Finally, add all the products one after another. As the overall weight percentage is 100%, So, there is no need to divide it by the summation of the weight percentage.

- Then, press
**Enter**to apply the formula. - It will give the final grade of a certain student using the weighted percentage.

### 2. Applying SUM Function

Our next method is based on **the SUM function**. This method is more of a conventional method. Here, you need to multiply its element and weight percentages in the **SUM** function. The main task of the **SUM** function is to add them. Follow the steps.

**Steps**

- First, merge the cells
**C14**and**D14**. - Then, select it and write down the following formula in the formula box.

**=**

`SUM(C5*D5,C6*D6,C7*D7,C8*D8,C9*D9,C10*D10,C11*D11,C12*D12,C13*D13)`

- Then, press
**Enter**to apply the formula. - It will give the final grade of a certain student using the weighted percentage.

### 3. Combining SUMPRODUCT and SUM Functions

Our third method is based on the combination of the **SUMPRODUCT** and **SUM** functions. This method can apply to every case to calculate the grades with weighted percentages in Excel. Sometimes, the total weighted percentage is higher or lower than **100%**. In that case, we can utilize the combination of **SUMPRODUCT** and **SUM** functions. It will provide us with the perfect solution.

**Steps**

- First, merge the cells
**C14**and**D14**. - Then, select it and write down the following formula in the formula box.

`=SUMPRODUCT(C5:C13,D5:D13)/SUM(D5:D13)`

**đź”Ž Breakdown of the Formula**

**SUMPRODUCT(C5:C13,D5:D13)/SUM(D5:D13): **The **SUMPRODUCT** function multiplies the first element (**C5**) of the first array with the first element (**D5**) of the 2nd array. Then, it multiplies the 2nd element (**C6**) of the first array with the 2nd element (**D6**) of the 2nd array. Follow the same procedures until the array ends. Finally, add all the products one after another. After that, using the **SUM** function, calculate the summation of the range of cells **D5** to **D13Â **which returns the total weighted percentage. Finally, it returns the final grade by using the value from **SUMPRODUCT** and **SUM** functions.

- Then, press
**Enter**to apply the formula. - It will give the final grade of a certain student using the weighted percentage.

## Things to Remember

- When the weighted percentage is equal to
**100%**, you can use the both**SUMPRODUCT**function and the combination of the**SUM**and**SUMPRODUCTÂ**functions. - But when the weighted percentage is less than or greater than
**100%**, you must use the combination of the**SUM**and**SUMPRODUCT**functions to get the final grades of a student.

## Conclusion

To calculate grades with weighted percentages in Excel, we have shown three effective methods through which you can get the final grade of a certain student. The weighted average takes the importance of each exam and finally gives the final results. To calculate this, we utilize three simple Excel functions.
