Grade Calculator
Calculate your weighted overall grade from assignment scores and weights.
When a course grade is built from multiple weighted components — assignments, quizzes, exams — the final grade isn't a simple average of the scores; it's a weighted average based on each component's importance.
Why weights change everything
A 95% on a 10%-weighted quiz and a 70% on a 40%-weighted final exam don't average to 82.5% — the final exam's higher weight pulls the overall grade closer to 70%, since it counts for much more of the total.
Frequently asked questions
What if my weights don't add up to 100%?
The calculator normalizes based on the weights you've entered so far, but for an accurate final grade, make sure your weights reflect the actual syllabus breakdown, which should sum to 100%.
Can I use this to predict what I need on a final exam?
Enter your known scores and weights, leave the final exam's weight in, and work backward by testing different exam scores to see what target you'd need to hit your desired overall grade.
