Free Test Score Calculator - Calculate Your Score Percentage
Quickly calculate test scores and percentages based on correct and incorrect answers.
Formula & Methodology
Test score percentage is calculated by dividing correct answers by total questions and multiplying by 100. This gives a percentage from 0% to 100% that maps to a standard letter grade. Some tests use partial credit or penalty scoring, where incorrect answers subtract from the total points earned.
- Score % = (Correct Answers / Total Questions) × 100
- Points Earned = Correct Answers × Points per Question
- Letter Grade = Score % mapped to grading scale (e.g., 90–100% = A)
Worked Example
Using the Test Scores Calculator: apply the formula above to your input values. For instance, Score % = (Correct Answers / Total Questions) × 100, then Points Earned = Correct Answers × Points per Question. The tool performs each step instantly and shows the result.
