How to use this calculator

Use this calculator to estimate a semester average from multiple grading periods, quarters, or major grade checkpoints. Enter each grade that should count toward the semester average.

Example

If a student has 85% for quarter 1 and 91% for quarter 2, the calculator can average those scores to estimate the semester grade. If your school weights grading periods differently, follow your school’s rules.

Common mistakes to avoid

• Do not mix semester grades with yearly grades unless your school uses that method.
• Make sure each grading period score is entered correctly.
• Check whether exams, projects, or final assessments count separately.

Semester average rules can vary by school. This tool gives a helpful estimate, but official grades should always follow the grading policy used by the teacher, class, or school.
