Weighted Average Calculation

The calculation or mechanism behind this tool is very simple. See the formula and definition below.

Defination: It’s a sum of each grade(G) multiple by credit/weight(W) and then divide whole result by total number of credits/weights(W).


Weighted Average =
G1 * W1 + G2 * W2 + G3 * W3 + … + Gn * Wn
W1 + W2 + W3 + … + Wn

Now let’s take an example to get more ideas.

Assume that there are three courses for that we have to find the weighted average.

The values are as below:

1) Quizzes have 90 numbers of grade and its weight is 30.
2) Mid Exam Paper has grade 85 and weight 20.
3) The physics course has grade 65 and weight 40.

In table format it looks like this:

Courses Grade Weight
Quizzes 90 30
Mid Exam 85 20
Physics 65 40

The final calculation is:

(30 * 90 + 20 * 85 + 40 * 65)
(30 + 20 + 40)
= 77.77777778
