Assignment Grade Calculator
Assignment grade calculator to quickly convert your scores into a final percentage, letter grade, and estimated GPA. Whether your teacher uses points (earned/possible) or weighted percentages, this tool helps you stay on track.
Points Mode Formula
If your assignment is graded by points, your final percentage is:
Final % = (Total Earned ÷ Total Possible) × 100
Example
You scored 45/50 and 18/20:
Total Earned = 45 + 18 = 63
Total Possible = 50 + 20 = 70
Final % = (63 ÷ 70) × 100 = 90%
Weighted Grade Calculation
Many rubrics use weights (for example: Content 50%, Grammar 20%, Formatting 30%). If you are wondering what is a weighted assignment, it simply means different parts count differently toward the final score.
Weighted % = (Σ (Weight × Score)) ÷ (Σ Weight)
Weighted Example
Content: 50% weight, you got 80%
Grammar: 20% weight, you got 90%
Formatting: 30% weight, you got 70%
Weighted % = (50×80 + 20×90 + 30×70) ÷ (50+20+30)
Weighted % = (4000 + 1800 + 2100) ÷ 100 = 79%
