Calculate a weighted grade
The weighted estimate is 85.9% because each category score is multiplied by its course weight.
Use it when your course categories have different weights.
A weighted grade calculator combines category scores according to the weights in your syllabus. For example, assignments may count 30%, quizzes 20%, exams 40%, and a project 10%. The calculator multiplies each score by its category weight, then adds the weighted parts together.
Use the Final Grade Calculator instead if your question is only “what score do I need on my final exam?” Use this page when the question is “how do my weighted categories combine into one course estimate?”
How to calculate weighted grade
To calculate a weighted grade, convert each category weight into a decimal, multiply it by the category score, then add the results. A 30% category weight becomes 0.30 in the formula.
Worked example: assignments, quizzes, exams, and project
Suppose your assignments score is 88 and assignments count 30% of the course. Quizzes are 82 and count 20%. Exams are 84 and count 40%. A project is 95 and counts 10%.
The weighted grade is 88 x 0.30 + 82 x 0.20 + 84 x 0.40 + 95 x 0.10 = 85.9%. This gives a course-grade estimate based on the categories you entered.
Weighted average vs weighted grade
The math behind a weighted average and a weighted grade is similar: each value is multiplied by its weight. The difference is context. A weighted grade uses course categories from a syllabus, such as assignments, quizzes, exams, projects, labs, or participation.
This calculator does not convert grades into GPA points. GPA depends on school-specific grade scales, credits, and transcript rules. It also does not calculate the final exam score needed to reach a target course grade.
Common mistakes and limitations
The most common mistake is entering category weights that do not match the syllabus. Another common mistake is entering raw assignment points when the calculator expects percentage scores. If your gradebook already applies dropped assignments or curves, enter the adjusted category score shown by the gradebook rather than every individual assignment.
- The calculator assumes category weights are percentage-based and transparent.
- Dropped assignments, grading curves, extra credit, minimum category rules, and instructor overrides are not modeled.
- The result is a planning estimate, not an official gradebook value, GPA, or final-exam-only calculation.
FAQ
Do the weights need to add up to 100%?
For a full course estimate, yes. If they do not total 100%, the calculator can still show a partial weighted result, but the estimate should be treated carefully.
Can this handle dropped assignments?
No. A basic weighted grade calculator assumes the category score you enter already reflects any dropped assignments or gradebook rules.
Is this the same as GPA?
No. Weighted course grade estimates a percentage course result. GPA depends on school-specific grade points and credit rules.
Is this a final grade calculator?
No. This calculator combines category scores and weights. Use the Final Grade Calculator when you need the score required on one final exam or final project.
What is the difference between weighted average and weighted grade?
The math is similar: each value is multiplied by its weight. A weighted grade is the course-specific version where the values are category scores and the weights come from the syllabus.
