Grade Calculator

Free grade calculator. Calculate your class grade from assignment scores and total points with letter grade.

How the Grade Calculator works

The calculator sums all points earned across assignments and divides by the total possible points to get a percentage. That percentage is then mapped to a letter grade using a standard grading scale (e.g., 90-100% = A, 80-89% = B).

Formula

Grade % = (Σ Points Earned / Σ Total Points) × 100
