About the Marks Percentage Calculator
Enter each subject’s marks and maximum marks and the calculator adds them up: total marks, the overall percentage (total ÷ total maximum × 100) and every subject’s percentage, with the working. Many colleges ask for the percentage of your best five subjects, often with a compulsory language — set “Best of” and tick Always count on the subject that must be included, and the calculator picks the highest of the rest.
It also checks every subject against a pass mark: 33% by default, the CBSE minimum, or any figure you set. With Theory and practical marks separately, each part is checked on its own as well as the total, as CBSE requires for Class XII subjects with practical work.
How to use it
- For each subject, type the marks you got and the maximum (out of). Add or remove rows as needed, or paste them from a spreadsheet or marksheet.
- Set Best of to the number of subjects your college counts (usually 5), and tick Always count for a compulsory subject such as English.
- Set the pass mark (33% for CBSE) or clear it to skip the check. Tick Theory and practical marks separately to enter the two parts.
- Read the overall percentage, the best-five percentage and the subject-wise table, then Copy result or Download CSV.
Examples
English 72, Mathematics 95, Physics 88, Chemistry 79, Computer Science 91, Physical Education 74 — each out of 100
Overall 499 / 600 = 83.17%. Best five with English: 72 + 95 + 91 + 88 + 79 = 425 / 500 = 85%
Without the compulsory English, the best five would be 95, 91, 88, 79 and 74: 427 / 500 = 85.4%.
45/50, 160/200 and 70/100
275 / 350 = 78.57% overall; the average of the subject percentages (90%, 80%, 70%) is 80%
The overall percentage weights each subject by its maximum marks.
Physics: theory 20/70, practical 28/30
Total 48/100 = 48%, but below the pass mark: theory 20/70 is 28.6%, under 33%
How the percentage is worked out
Overall percentage = (sum of marks obtained) ÷ (sum of maximum marks) × 100. When every subject has the same maximum this equals the average of the subject percentages; when maxima differ, subjects with more marks count for more, and the calculator shows the plain average of the subject percentages as well.
For best of N, the subjects you mark “Always count” are taken first, then the remaining subjects with the highest percentages (with equal maximum marks, the highest marks), and their total is divided by their total maximum.
CBSE: pass marks, no aggregate, best five
The CBSE Examination Bye-Laws set the pass mark in each subject at 33%; in Class XII a subject with practical work needs 33% in theory and 33% in practical separately, besides 33% overall (Rules 40.1 and 41.1). The same rules say no overall division, distinction or aggregate is awarded.
CBSE’s notice adds that the Board does not calculate or declare a percentage of marks: if a percentage is needed for higher education or a job, the admitting institution or employer works it out, and when you took more than five subjects it decides which best five count. So check that institution’s own rule — for example, whether a language must be one of the five.

Limitations
- Boards, universities and colleges count percentages differently — which subjects, whether additional or vocational subjects and grace marks count — so use the rule of the institution that asks for the figure.
- The pass check compares percentages only; it does not apply grace marks, compartment rules or a board’s minimum for internal assessment.
- Up to 20 subjects, with maximum marks up to 1,00,000 each.

Frequently asked questions
How do I calculate my percentage of marks?
Add the marks you got in all subjects, divide by the total maximum marks and multiply by 100. With 499 out of 600: 499 ÷ 600 × 100 = 83.17%.
How do I work out my best of five percentage?
Take the five subjects with the highest marks (including any compulsory subject, such as English, that your college requires), add their marks and divide by 500 if each is out of 100. Set Best of to 5 and tick Always count on the compulsory subject.
Does CBSE give an aggregate percentage or division?
No. Its bye-laws say no overall division, distinction or aggregate is awarded, and its notice says the Board does not calculate a percentage — the institution or employer that needs one works it out.
What are the pass marks in CBSE?
33% in each subject. In Class XII, a subject with practical work needs 33% in theory and 33% in practical separately, besides 33% overall — tick Theory and practical marks separately to check both parts.
Why is my overall percentage different from the average of my subject percentages?
Because your subjects have different maximum marks: the overall percentage divides total marks by total maximum, so a 200-mark paper counts twice as much as a 100-mark one. The average of the subject percentages treats each subject equally.
