What is a Grade Calculator?
This tool calculates your overall grade as a percentage and letter grade. It supports two modes:
- Points mode: Enter earned points and total possible points
- Weighted mode: Enter multiple scored items each with a weight percentage
Grading scale
| Letter | Percentage |
|---|---|
| A | 90% and above |
| B | 80% – 89% |
| C | 70% – 79% |
| D | 60% – 69% |
| F | Below 60% |
How to use this tool
Points mode: Enter your earned points (e.g. 87) and the total points possible (e.g. 100).
Weighted mode: Add each graded item (quiz, exam, homework), enter your score (0–100%), and assign each item a weight percentage. The tool calculates the weighted average.
Example use cases
- Exam: Scored 42 out of 50 points → 84% → B
- Course grade: Homework (30%), midterm (30%), final (40%) → weighted final grade
- What-if analysis: Estimate your grade before taking a final exam
