How to use this calculator

Enter the points earned and the total points possible to calculate the grade percentage. This is useful for homework, quizzes, tests, classwork, projects, and quick grade checks.

Example

If a quiz is worth 20 points and a student earns 18 points, enter 18 and 20. The calculator will show 90%.

Common mistakes to avoid

• Do not enter a percentage in the total points field.
• Make sure total points is greater than zero.
• Check how extra credit is handled by the teacher or school.

Different schools may use different letter-grade scales, so always follow the grading rules used by the class or school.
