Generally, school or college students are calculating the final grade manually to check what grade they need on their final exam to achieve the targeted grade in a class.

Even I was doing the same thing when I was a student. But it was a very frustrating and boring task to do it with pen and paper. Because I had to remember the formula, then place the values on it, and find the results. Sometimes it gives false results. Therefore, I turned to online resources. There were a few calculators on the Internet. But none of them met my standard.

Since I am a front-end developer now. So, I thought why don't I have to make a good final grade calculator by myself? It will help lots of students or parents who are regularly looking for this type of tool. Also, it will save time and effort.

Finally, I made it. And... here is the result. I hope it will help you out.

How to Calculate Final Exam Grade?

It's very easy to figure out the final exam grade using the formula. It's just simple math that you can do on any calculator.

  FG =  
(RG - (1 - WT) × CG)


FG = Final Exam Grade
RG = Required Grade that you want for a class
WT = Final Exam Weight
CG = Current Grade

Let's take an example to understand it more deeply.


Suppose my current grade in math class is 77% (or C+). Now I want to score at least 85% (or B) in class for the term. Final exam weight is 45%. Find out what grade(percentage) do I need on my final exam?

Firstly, apply the values to the formula.

  FG =  
(RG - (1 - WT) × CG)

CG = 77%
RG = 85%
WT = 45% = (Convert into decimal: 45 ÷ 100 = 0.45)

So, let's start the calculation.

  FG =  
(85 - (1 - 0.45) × 77)
  FG =  
(85 - (0.55 × 77))
  FG =  
(85 - 42.35)
  FG =  
FG = 94.78%

Therefore, I need to score 94.78% on my finals to get 85% in class.

It's a little bit confusing to do it manually. Right? No worries! Use the final grade calculator to make it easy, fast, and accurate. Also, you don't need to remember the formula all the time.
