What Is a Grade Calculator?

A grade calculator helps students estimate their overall course grade using assessment scores and their assigned weights. You can use it for assignments, quizzes, projects, midterms, final exams, and other graded activities.

How to Calculate a Weighted Grade

Each assessment contributes to the final result according to its percentage weight.

Weighted Score = Score × Weight ÷ 100

The overall percentage is the sum of all weighted scores.

Example

Suppose you receive 80% on an assignment worth 20% of your course grade and 90% on an exam worth 40%. The calculator combines these weighted scores with your other assessments to estimate your overall grade.
