Enter grades and weights & press the Calculate button:

%
(weights must be in %).

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

Weighted grade = w1×g1+ w2×g2+ w3×g3+...

#### Example

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

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

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

The weighted average grade is calculated by:

= w1×g1+ w2×g2+ w3×g3

= 30%×80+ 50%×90+ 20%×72 = 83.4

When the weights are not in percent (hours or points...), you should also divided by the sum of the weights:

Weighted grade = (w1×g1+ w2×g2+ w3×g3+...) / (w1+w2+w3+...)

#### Example

3 points Math course with grade of 80.

5 points Biology course with grade of 90.

2 points History course with grade of 72.

The weighted average grade is calculated by:

= (w1×g1+ w2×g2+ w3×g3) / (w1+w2+w3)

= (3×80+ 5×90+ 2×72) / (3+5+2) = 83.4
