Calculate your overall weighted class grade from homework, quizzes, exams, and any other graded categories.
Add your grade categories, then click Calculate
This free grade calculator combines your scores across weighted categories — homework, quizzes, exams, projects, participation, or anything your syllabus defines — into a single overall class grade and letter grade, updating live as you adjust any value.
Add a row for each graded category in your class, entering its weight (the percentage of your final grade it represents) and your score in that category (as a percentage). The calculator multiplies each score by its weight, sums the results, and divides by the total weight entered to produce your overall weighted grade, then converts that percentage into a standard letter grade.
Students tracking their current standing in a class throughout the semester, anyone testing "what-if" scenarios for an upcoming exam or assignment, and students figuring out what score they need on remaining work to hit a target grade.
The weighted average behind your overall grade
A category worth 50% of your grade affects your overall score five times as much as one worth 10%.
Each score is scaled by its weight before summing, then the total is divided by the sum of weights to return to a percentage.
The final weighted percentage is converted into a letter grade using a standard grading scale.
From syllabus weights to your overall grade
Type a category name (like Homework or Exams), its weight percentage, and your score percentage for that category.
Click "Add Category" for every graded component of the class.
See your overall weighted grade and letter grade instantly.
