Calculate Your Course Grade
Enter the name of each assessment, your score, and its weight. The total weights should normally add up to 100%.
What is a Grade Calculator?
A grade calculator helps students determine their overall course grade by combining scores from assignments, quizzes, exams, projects and other assessments according to their weights.
How Does a Grade Calculator Work?
Each assessment contributes to the final grade according to its percentage weight. For example, if an exam is worth 30% of your course grade, its score contributes 30% of the final weighted grade.
Grade Calculator Formula
Weighted Grade = Σ (Score × Weight) ÷ 100
Example
Suppose you score 90% on an assignment worth 20%, 80% on an exam worth 30%, and 95% on a project worth 50%. The calculator combines each score with its corresponding weight to calculate the overall course grade.
Common Letter Grade Scale
- A: 90–100%
- B: 80–89%
- C: 70–79%
- D: 60–69%
- F: Below 60%
Grade boundaries can vary between schools, colleges and universities, so always check your institution's grading policy.
