How to use Grade Calculator
Add one row per assignment with its score, maximum and weight. Choose weights or total points and a letter scale. The grade updates as you type.
How it works
Weighted grade = Σ(score ÷ maximum × weight) ÷ Σ weights. When weights add up to less than 100 %, the result is the grade on the work graded so far.
Example
Homework 92 % (weight 20), quizzes 78 % (15), a midterm of 81 % (25) and a 45/50 project (15) give 85.13 %, a B.
