Weighted Grade Calculator
Combine homework, quizzes, midterms and finals into one course grade using each category's syllabus weight.
If your weights don't add to 100%, that's fine mid-semester: the result is your grade on the work completed so far (the standard 'current grade' your LMS shows). Pair this with the final grade calculator โ feed this number in as your current grade and the missing weight as the final's weight.

About Weighted Grade Calculator
Most course grades aren't simple averages โ the syllabus weights homework at 20%, quizzes at 25%, the midterm at 25%, the final at 30%, and your real grade is the weighted blend. This weighted grade calculator takes any number of "score weight" pairs and computes the exact weighted average, the same arithmetic your LMS runs behind the scenes. Mid-semester, when the weights you've completed don't yet total 100%, it automatically renormalizes and reports your grade-so-far on completed work โ which is precisely the number you feed into a final-grade calculator to plan the rest of the term. No fixed number of rows, no rigid form: paste your categories and read your grade.

Frequently asked questions
How do I calculate a weighted grade by hand?+
Multiply each category score by its weight, add the products, and divide by the sum of the weights. Example: 88ร20 + 92ร25 + 79ร25 + 85ร30 = 8585; divide by 100 โ 85.85%. When weights total 100 the division is trivial; when they don't, dividing by the actual weight sum gives your renormalized grade-so-far.
What if my weights don't add up to 100%?+
Mid-semester that's expected โ the final exam's 30% hasn't happened yet. Dividing by the weights you've completed (say, 70) gives your current standing on finished work, which is exactly how Canvas and Blackboard display 'current grade'. The calculator's verdict tells you which interpretation you're seeing.
How are weighted grades different from points-based grades?+
In a points system every assignment's influence is proportional to its point value, and your grade is points earned รท points possible. In a weighted system, categories have fixed shares regardless of how many assignments they contain โ a 10-question quiz category worth 25% outweighs 500 points of homework worth 20%. Check your syllabus to know which one your course uses.
Can I use this for dropped-lowest-score policies?+
Yes โ just compute each category's score after the drop (average your quiz scores excluding the lowest, for example) and enter that adjusted score with the category's weight. The weighting math is identical; the drop only changes the category score you feed in.
