Example calculations
Example 1: Single exam
If a student gets 72 marks out of 100, then the percentage is: (72 / 100) × 100 = 72%.
Example 2: Board exam result
If marks are 391 out of 450, then: (391 / 450) × 100 = 86.89%.
Example 3: College semester total
If total obtained marks are 820 out of 1000, percentage is: (820 / 1000) × 100 = 82%.
Percentage for multiple subjects
Many students make the mistake of averaging subject percentages directly. The safest method is:
- Add all obtained marks from every subject.
- Add total maximum marks from every subject.
- Apply the same formula once on the final totals.
This method gives an accurate overall percentage, especially when subjects have different maximum marks.

These are not the same:
