Test Grade Calculator
A Test Grade Calculator helps you quickly convert your test performance into a percentage, letter grade, and even an estimated GPA. Whether you know how many questions you got wrong, how many you got correct, or your total points, this tool gives you a clear result in seconds.
Test Grade Calculation: Formula and Examples
1) If you know total questions and wrong answers
Formula: Percentage = ((Total − Wrong) ÷ Total) × 100
Example: Total = 40, Wrong = 6
Percentage = ((40 − 6) ÷ 40) × 100 = (34 ÷ 40) × 100 = 85%
2) If you know total questions and correct answers
Formula: Percentage = (Correct ÷ Total) × 100
Example: Total = 50, Correct = 45
Percentage = (45 ÷ 50) × 100 = 90%
3) If your test is points-based
Formula: Percentage = (Points Earned ÷ Points Total) × 100
Example: Earned = 42, Total = 50
Percentage = (42 ÷ 50) × 100 = 84%
