Exam Percentage Calculator
Turn your exam marks into a percentage — for a single subject or an overall aggregate across subjects.
How to calculate exam percentage
An exam percentage expresses your marks obtained as a portion of the maximum marks, out of 100: percentage = (marks ÷ maximum) × 100. For an overall result across several subjects, total all the marks obtained and divide by the total maximum.
Real-world example
Score 76 out of 90 and your percentage is (76 ÷ 90) × 100 = 84.4%. Across five subjects scoring 78, 85, 69, 92 and 81 out of 100 each, the aggregate is 405 ÷ 500 × 100 = 81%.
Weighted results
If components carry different weights — say finals 70% and coursework 30% — multiply each percentage by its weight and add them: 80% in finals and 90% in coursework gives (80 × 0.7) + (90 × 0.3) = 83%.
Frequently asked questions
