Test Grade Calculator
Convert points earned and points possible into a percentage and an optional common letter grade.
Method
Percentage score = points earned ÷ points possible × 100. When the common letter-grade option is selected, the page uses A ≥ 90%, B ≥ 80%, C ≥ 70%, D ≥ 60%, and F below 60%. Extra-credit scores above 100% are allowed.
Worked example
A score of 42 points out of 50 is 84.00%. Under the optional common 90/80/70/60 scale, that corresponds to a B.
When this is useful
Useful for students, teachers, tutors, and parents who need to translate a points-based score into a percentage quickly.
Privacy
The values you enter into this calculator are processed in your browser by Practical Tools Hub application assets. The calculator does not need to send your calculation inputs to a third-party calculation service.
Limitations
Letter-grade cutoffs vary by instructor, course, school, and grading policy. The optional scale here is only a common example. This tool does not account for weighted categories, dropped assignments, curves, or course-specific policies.
