How to Use the Final Grade Calculator?

There are three tabs for three different final grade calculations. Let's know each one by one.

1. Final Grade

Simply input the current grade, desired grade, and final exam weight. As a result, the tool returns the final grade needed to achieve the desired grade.

2. Overall Grade

This calculator is used to find the overall course grade by inputting the current average grade, final exam grade, and final exam weight.

3. Multiple Grades

This tool lets you compute the final grade needed by inputting multiple grades and weights. To add multiple grades, use the '+' button.

Also, the tool supports Percentage or Letter grades. Just select the grade type, enter the required values, and press the 'Calculate' button to get the final grade results.

Note: Make sure the sum of weights must be equal to the total weights.

Grade Weight + Final Exam Weight = Total Weights

How to Calculate the Final Grade?

The final grade is calculated using the following formula:

F =  
( R - ( 1 - W ) × C )
W

Where,

F = Final Exam Grade,
R = Required Grade that you want for a class,
W = Final Exam Weight,
C = Current Grade.

Let's take an example.

Example:

Suppose, the current grade is 77%, the desired grade is 85%, and the final exam weight is 45%. Find out the grade needed for the final exam.

Solution:

Here,

Current Grade (C) = 77%,
Required Grade (R) = 85%,
Final Exam Weight (W) = 45% (In decimal: 45 / 100 = 0.45).

Now, put all the values in the final grade formula.

F =  
(R - (1 - W) × C)
W
F =  
(85 - (1 - 0.45) × 77)
0.45
F =  
(85 - (0.55 × 77))
0.45
F =  
(85 - 42.35)
0.45
F =  
42.65
0.45

Final Grade Needed = 94.78%.
