How to calculate a percentage grade
Divide the points earned by the points possible, then multiply by 100 to get a percentage. Map to the standard letter scale: A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60, F below 60. See the full grading chart for the plus/minus breakdown.
Formula
percentage = (points earned ÷ points possible) × 100
Example
42 out of 50 → 42 ÷ 50 = 0.84 → 84% (B)
