This calculator use this formula

Where,

F = Final exam grade

G = Grade you want for the class

w = Weight of the final exam, divided by 100 (put weight in decimal form vs. percentage form)

C = Your current grade

Example, My grade in English class is 85%. I want to get at least an A- or 90% in the class for the term. What score do I need on the final exam if it is worth 40% of my grade?

Using the Final Exam Grade formula above, I want a 90 in the class, and I currently have an 85. The final is worth 40% of the term grade.

First, convert the weight of the final exam from percent to decimal: 40 ÷ 100 = 0.40

The weighted grade is equal to the sum of the product of the weights (w) in percent (%) times the grade (g):

Example

Math course with grade of 80 and weight of 30%.

Biology course with grade of 90 and weight of 50%.

History course with a grade of 72 and weight of 20%.

The weighted average grade is calculated by:

Weighted grade =

 = w₁×g₁+ w₂×g₂+ w₃×g₃

 = 30%×80+ 50%×90+ 20%×72 = 83.4
