The Percentage Formula
The percentage of marks is calculated with one simple formula:
- Percentage = (Marks Obtained ÷ Total Maximum Marks) × 100
This works for a single subject, a full exam, or an entire academic year, as long as you use the matching totals.
Step-by-Step Calculation
Suppose you scored 425 marks out of a total of 500 across five subjects:
Add Up Marks Obtained
Total marks obtained across all subjects = 425.
Find the Maximum Marks
Five subjects of 100 marks each gives a total maximum of 500.
Divide and Multiply by 100
Percentage = (425 ÷ 500) × 100 = 85%.

For a single subject, divide the marks in that subject by its maximum. For an overall percentage, add every subject's marks and divide by the combined maximum. The overall percentage is not simply the average of individual percentages unless each subject carries the same maximum marks.
Frequently Asked Questions
What is the formula for percentage of marks?
Percentage = (Marks Obtained ÷ Total Maximum Marks) × 100. For example, 425 out of 500 is 85%.
How do I calculate overall percentage for multiple subjects?
Add the marks from all subjects, divide by the combined maximum marks, and multiply by 100.
Is average of subject percentages the same as overall percentage?
Only when every subject has the same maximum marks. Otherwise, use total marks over total maximum for an accurate result.
