Grade Percentage Calculator
A fast points-based grade calculator for assignments, quizzes and exams with a familiar US letter-grade reference scale.
Points to percentage
Use this calculator when an assignment is scored in points rather than questions. The percentage is the points earned divided by the points possible, multiplied by 100.
grade % = points earned ÷ points possible × 100
Single assignment vs. a points-based course total
For one assignment, enter that assignment's earned and possible points directly. If your course is a pure points system with no category weighting, add the earned points across the included assignments, add the possible points, and enter those two totals here.
If homework, exams or other categories have separate percentage weights, do not combine them as raw points unless your syllabus says to. Use the Weighted Grade Calculator instead.
Letter-grade cutoffs, rounding and extra-credit policies vary by course, so treat the displayed letter as a reference and compare the percentage with your syllabus.
