Weighted grade calculator

Your weighted grade

84.5% B

from the 65% of your class graded so far

35% of the class is still open. See what you need on it.

Your lowest category is midterm at 78%. A practice test from your notes before the next one is the fastest way to raise it.

Three study sets are free.

How to calculate a weighted grade

In a weighted class, each category counts for a set share of the grade: homework for 20%, the midterm for 25%, the final for 35%. You multiply each category grade by its weight, add the results, and divide by the total weight.

Weighted grade = (weight × grade + weight × grade + …) ÷ (sum of the weights)

Say homework is 92% and worth 20%, quizzes are 85% and worth 20%, and the midterm is 78% and worth 25%. That is 20 × 92 + 20 × 85 + 25 × 78 = 5490. The graded weights add up to 65, and 5490 ÷ 65 = 84.5%, which is a B.

Your grade before the final

Most of the year, part of the class has no grade yet. The calculator divides by the weight that is graded, not by 100, so 84.5% in the example is your grade on the 65% of the class that is done.

The final still counts for the other 35%. To see the score you need on it for the grade you want, use the final grade calculator. The weighted calculator links to it with your numbers filled in.

Raise the lowest category

Once you see your categories side by side, the one that pulls your grade down is usually clear, and it is often an exam category. Rereading your notes feels like studying, but answering questions is what makes the material stay.

Add your notes, slides or a PDF to Lexie and you get a practice test from your own class material, and the questions you miss come back until you know them. You can also start from the quiz generator.

Frequently asked questions

Multiply each category grade by its weight, add the results, and divide by the total weight. With homework at 92% (20%), quizzes at 85% (20%) and a midterm at 78% (25%), that is (20 × 92 + 20 × 85 + 25 × 78) ÷ 65, which gives 84.5%.
A grade where some parts of the class count more than others. A final worth 35% moves your grade more than homework worth 10%, even if both are out of 100. Most high school and college classes list the weights in the syllabus.
In the syllabus, usually under grading or assessment. Your school portal often shows them next to each category too. If your class has no weights, every assignment counts by its points instead.
Then you do not need weights. Add up the points you have earned, divide by the points possible so far, and that is your grade. Bigger assignments count more because they are worth more points.
The calculator divides by the weight that has a grade so far, not by 100. If 65% of the class is graded, your grade is the weighted average of that 65%. To see what you need on the rest, use the final grade calculator with that grade.
The calculator still works: it scales the grade to the weights you entered. A total above 100% usually means a typo or an extra credit category, so check your syllabus.
