How it's calculated
The marks you scored are added together, the maximums are added together, and the first is divided by the second once. That order matters: averaging each subject's own percentage gives a different, wrong answer whenever the subjects are out of different maximums.
Estimate only. Official results, marks and eligibility are decided by the University Grants Commission. Verify on the official website.
Worked example: two subjects, different maximums
A candidate scores 80 out of 100 in one subject and 45 out of 50 in another. Adding first gives 125 out of 150, which is 83.33%. Averaging the two subject percentages — 80% and 90% — would give 85.0%, which is wrong: the subject out of 100 carries twice the weight of the one out of 50.
When a plain percentage is the wrong answer
The arithmetic on this page is fixed, but the question of which marks go into it is not, and that is decided by whoever issues your result. Three cases come up again and again:
- Not every subject counts. Some boards and universities form an aggregate from a stated set of subjects rather than everything on the marksheet, and some admissions bodies count a different set again for their own cut-off. Put in the subjects that rule names, not all of them.
- Theory and practical may be weighted. Where a subject is split, the maximum to use is the one the regulation gives for the combined subject, not the theory paper alone.
- A grade point average does not divide into a percentage. If your marksheet shows a CGPA or SGPA, the conversion is set by your university and differs between them — some multiply, some subtract a constant first, some publish a table, and some state that no conversion is permitted. Use theCGPA to percentage calculator, which asks whose rule to apply and names the regulation behind it.
Frequently asked questions
How do I work out the percentage of marks?
Add up the marks you scored, add up what those subjects are out of, divide the first by the second and multiply by 100. The calculator does exactly that, and it adds the totals before dividing rather than averaging each subject separately.
Why not just average the percentage of each subject?
Because it gives the wrong answer whenever the subjects are out of different maximums. Scoring 125 out of 150 is 83.33%, but averaging 80% and 90% would tell you 85.0%. A subject out of 100 has to pull twice as hard as one out of 50, and only adding the totals first does that.
Does this work for one subject as well as many?
Yes. Fill in a single row for a single paper, or one row per subject for an aggregate. Rows you leave blank are ignored, so you can keep spare rows on the page.
Is a percentage of marks fixed by any rule?
No. The arithmetic is the same everywhere and no authority prescribes it. What authorities do prescribe is how an aggregate is formed: which subjects count towards it, whether practical marks are included, and how a grade point average converts. Those rules differ, and where one applies it beats the plain arithmetic.
My marksheet shows a CGPA, not marks. Can I use this?
No, and this is the commonest mistake. A CGPA does not become a percentage by dividing: each university sets its own conversion, and some publish a table or forbid conversion altogether. Use the CGPA to percentage calculator, which asks whose rule to apply and names the regulation it follows.
How is the result rounded?
To 2 decimal places, and only at the very end. Rounding each subject first and then averaging would drift, which is why the calculator keeps the exact value until the last step.
Can I enter marks higher than the maximum?
No. The calculator stops and says which row is wrong, because marks above the maximum are almost always a typo, and a percentage over 100 would be carried silently into everything after it.
