Basics
How grade calculation works
Percentage grade
A percentage grade compares what you earned with what was possible.
Weighted grades
Weighted grades let tests, projects, finals, or categories count more than smaller assignments.
Ungraded work
Leave the score blank for ungraded work. Enter 0 only if your syllabus counts missing work as zero.
Letter grades
Letter grade cutoffs vary, so compare the result with your class grading scale.
Formula
Grade formula explanation
Points grade
Grade = Total Points Earned ÷ Total Points Possible × 100This calculates the percentage earned across all point-based assignments.
Weighted grade
Weighted Grade = Σ(Score Percentage × Weight) ÷ Total WeightThis calculates a grade when categories or assignments have different weights.
Final exam needed
Required Final = (Target − Current × (1 − Final Weight)) ÷ Final WeightThis estimates the final exam score needed to reach a target course grade, with weights as decimals. It assumes your current grade represents all coursework other than the final.
FAQ
Grade calculator questions
