How to Calculate Percentage of Marks (Exam Score Guide)
Calculating your exam percentage seems basic until you're aggregating across subjects with different total marks. Here's how to do it right.
The basic formula
Percentage = marks obtained ÷ total marks × 100. Scored 432 out of 600? That's 72%. The exam marks percentage calculator does it and shows your grade band.
Aggregate across subjects
Add all your obtained marks, add all the total marks, then divide. Five subjects of 100 each where you scored 78, 85, 62, 90, 71: that's 386 ÷ 500 × 100 = 77.2%. Don't average the individual percentages unless every subject has the same total.
Convert from CGPA if needed
If your result is in CGPA, convert with the CGPA to percentage converter using your institution's official formula — important for application forms.
What's a good percentage?
It varies by board and competition, but broadly: 75%+ is a strong first division, 60–75% solid, 50–60% passing comfortably. For competitive admissions, percentile (your rank relative to others) often matters more than raw percentage.
