Grade Calculator

Calculate a weighted final grade from the score and percentage weight of each component, such as homework, midterm, and final exam.

About Grade Calculator

A weighted grade counts each component in proportion to its weight: grade = sum of (score × weight) ÷ sum of weights. With scores of 85, 78, and 90 weighted 30%, 30%, and 40%, the result is 84.9. Because the calculator divides by the total weight entered, weights that do not add up to 100% still give the average of the work graded so far, and it flags that the total is not 100%.

Questions about Grade Calculator

What if my weights do not add up to 100%?

The result is still correct for the components you entered, because the total is divided by the sum of the weights. It shows your current standing before the remaining work is graded.

Can I use points instead of percentages?

Yes, if each score is on the same scale. Convert each component to a percentage first (points earned ÷ points possible × 100), then enter that percentage with its weight.
