Weighted Grade Calculator
Find your true average by factoring in the weight of each assignment, project, and exam in your course.
How It Works
Weighted Avg = Σ (Score × Weight) / Σ (Weights)Multiply each assignment score by its weight, sum all weighted scores, then divide by the total sum of all weights. This produces your true weighted average, accounting for the relative importance of each assignment.
Quick Tips
Common Mistake
Simple averages ignore weight — a 40% exam counts more than a 5% homework.
Check Weights
Ensure all weights in your syllabus add up to 100%. If not, ask your professor.
Strategic Focus
Prioritize high-weight assignments for maximum impact on your overall grade.
Multiple Categories
Group assignments by category (homework, quizzes, exams) for easier tracking.
Step-by-Step Instructions
- 1Enter each assignment or category name.
- 2Enter the score/grade you received for each.
- 3Enter the weight of each assignment (e.g. 20%).
- 4See your weighted average calculated instantly.
Understanding Weighted Categories
In most university and high school classes, assignments do not contribute equally to your final grade. A 'weighted' system means the teacher assigns different percentages of importance to different categories.

To find a weighted grade manually: multiply each category's average score by its weight (as a decimal). (80 * 0.2) + (90 * 0.8) = 16 + 72 = 88% overall.
Frequently Asked Questions
What is the difference between weighted and unweighted grades?▼
An unweighted grade treats all assignments equally, while a weighted grade factors in how much each assignment counts toward your final grade.
What if my weights don't add up to 100%?▼
The calculator normalizes the weights automatically, so it works even if weights don't sum to 100%. However, check with your instructor in case there are missing components.
Can I use this for multiple courses?▼
Yes — calculate each course separately and then use the results to determine your overall semester GPA.
