Use this Test Grade Calculator to calculate a test percentage from the number correct, number wrong, or points earned. It can also estimate a letter grade using the editable grade thresholds in the calculator.
Calculation Method
Percentage = correct answers ÷ total questions × 100
If the number wrong is entered:
Correct = total − wrong
For a points-based test:
Percentage = points earned ÷ total points × 100
Example
If a test has 40 questions and 7 are wrong:
Correct = 40 − 7 = 33
Grade = 33 ÷ 40 × 100 = 82.5%
The letter grade depends on the grading thresholds selected in the calculator.
Important Note
Letter-grade cutoffs are not universal. Use the grading scale provided by your teacher, school, course, or exam board.
If questions have different point values or partial credit, use points earned and total points rather than simple question counts.
