Marks percentage calculator
Percentage of marks = marks obtained ÷ maximum marks × 100. For a whole marksheet, add your marks in every subject and divide by the total of their maximum marks: 432 out of 500 is 86.4%. When a college counts only your best five subjects, add those five instead.
Example: all 6 subjects
527 out of 600 marks
- English86/100 · 86%
- Mathematics92/100 · 92%
- Science88/100 · 88%
- Social Science81/100 · 81%
- Hindi85/100 · 85%
- Information Technology95/100 · 95%
How to calculate the percentage of marks
Add the marks you obtained, add the maximum marks, divide the first total by the second and multiply by 100. Five subjects marked out of 100 with 86, 92, 88, 81, 85 come to 432 out of 500:
432 ÷ 500 × 100 = 86.4%
For one exam the rule is the same: 43 out of 50 is 86%. Common single scores have their own pages, such as 43 out of 50 and 17 out of 20, and the test grade calculator takes any score.
Subjects with different maximum marks
Add the marks and the maximums; do not average the subject percentages. With 72 out of 80 and 45 out of 70, the total is 117 out of 150, 78%. Averaging 90% and 64.29% would give 77.14%, because it counts the 70-mark paper as much as the 80-mark one.
When every subject is out of 100, both ways give the same answer.
Best five: which subjects count
On Class 12 marksheets CBSE prints marks for each subject and no overall percentage. Its Senior School curriculum says the percentage is to be worked out by the norms of the college or institution you apply to, so the subjects that count are that college’s choice, often the best four or five. Read the admission notice for its rule, then tick “Count only my best” above.
With a sixth subject at 95, the six subjects above total 527 out of 600, 87.83%; the best five total 446 out of 500, 89.2%.
Marks you need for a percentage
Multiply the maximum marks by the percentage you need. 90% of 500 is 450 marks, so the 432 above are 18 short. Enter the percentage in the calculator to see the gap for your own marks.
Results that show a CGPA instead of marks, such as CBSE Class 10 results from its grading years, need a conversion first: CGPA to percentage.
