Weighted Grade Calculator is designed for the exact search intent behind “weighted grade calculator”. Calculate a course or category average when assignments, exams or grade categories contribute different percentages to the final result. Calculate a course or category average when assignments, exams or grade categories contribute different percentages to the final result. Weighted grade formula Convert each weight to a decimal, multiply it by the corresponding score, then add the contributions: weighted grade = Σ(score × weight) . Weights should be checked For a complete course calculation, weights normally total 100%. If they total less, you may be calculating only the graded portion; if they exceed 100%, review the syllabus or extra-credit rules. Points vs weights A weighted grade is different from simply dividing total points earned by total points possible when categories carry independent weights. Worked example: If exams are 80% of the grade at 90% and homework is 20% at 75%, the weighted grade is 90×0.80 + 75×0.20 = 87%. Common practical uses include Calculate category-weighted course grades; Model assignment scenarios; Check syllabus grade weights; Compare current and target grades. Important limitations: Dropped assignments, extra credit and category caps can require special rules. Missing categories can make a current-grade calculation differ from the eventual final grade. Rounding policy can differ by instructor. Key questions this page should answer include: How do I calculate a weighted grade? Multiply each score by its decimal weight and add the weighted contributions. Do grade weights have to total 100%? For a complete ordinary weighted course they usually do, though special grading policies can differ. What if my weights total less than 100%? You may be calculating only part of the course; interpret the result according to the syllabus. Is a weighted grade the same as total points? Not when categories or assignments have independent percentage weights. How does extra credit affect a weighted grade? It depends on the course policy; extra credit can be added within a category or outside the normal 100% structure. The page should stay focused on this differentiator: Exact weighted-average math plus weight-total diagnostics; avoid mixing it with simple points percentage.
How to use this tool
Weighted grade formula
Convert each weight to a decimal, multiply it by the corresponding score, then add the contributions: weighted grade = Σ(score × weight).
Weights should be checked
For a complete course calculation, weights normally total 100%. If they total less, you may be calculating only the graded portion; if they exceed 100%, review the syllabus or extra-credit rules.
Points vs weights
A weighted grade is different from simply dividing total points earned by total points possible when categories carry independent weights.
Examples
Two-category example
If exams are 80% of the grade at 90% and homework is 20% at 75%, the weighted grade is 90×0.80 + 75×0.20 = 87%.
Common use cases
- Calculate category-weighted course grades
- Model assignment scenarios
- Check syllabus grade weights
- Compare current and target grades
