Common Grade Calculation Formulas
Showing the underlying calculation makes it easier to understand and verify a result. The mathematical percentage is different from the letter-grade label assigned by a particular grading scale.
Test Percentage
percentage = (correct answers ÷ total questions) × 100
This applies when all questions have equal value.
Points Percentage
percentage = (points earned ÷ points possible) × 100
Use this for points-based assignments, tests and exams.
Weighted Grade
weighted grade = Σ(score × category weight)
Each category contributes according to its assigned weight.
Check the Grading Scale Used by Your Course
Letter-grade cutoffs are not universal. Schools, colleges, instructors and individual courses can use different grading thresholds. A percentage calculation can be exact even when its letter-grade interpretation varies.
Use the grading scale specified in your course syllabus or grading policy whenever an exact letter grade matters.
Explore Grading Scales →| Letter Grade | Example Minimum | Example Range |
|---|---|---|
| A | 93% | 93–100% |
| A− | 90% | 90–92% |
| B+ | 87% | 87–89% |
| B | 83% | 83–86% |
| C | 73% | 73–76% |
| D | 60% | 60–69% |
| F | Below 60% | Below passing threshold |
