Examples

Weekly assignments

Four assignments: 92%, 88%, 76%, and 100%.

Average = (92 + 88 + 76 + 100) ÷ 4 = 89%.

Weighted categories

Homework 40% (95%), tests 60% (82%).

0.4 × 95 + 0.6 × 82 = 87.2%.

Missing assignment

Quiz average is 85% but one quiz is a zero.

Include the zero to see the true current average.

How it works

  1. 1 List each assignment or category with its score.
  2. 2 Add weights if categories contribute differently.
  3. 3 Calculate the weighted or simple average.
  4. 4 Review the output and adjust as assignments change.

FAQ

Can I use this for weighted grades?

Yes. Add the category weights and multiply each score by its weight.

What if I only have a few assignments?

Use a simple average until you have enough data for weights.

Is this the same as a GPA calculator?

No. GPA calculators use credit hours and grade points; this is for a single class.
