How to Calculate Percentage of Marks – Formula & Examples
Calculating the percentage of marks is simple with the right formula. The most common method is:
Percentage (%) = (Obtained Marks ÷ Total Marks) × 100
For example, if you scored 380 out of 500 in an exam, your percentage is calculated as:
(380 ÷ 500) × 100 = 76%
This formula works for exam results, test scores, and grade calculations. Students often search for “how to calculate percentage of marks,” “marks percentage formula,” “exam percentage calculator,” and “total marks to percentage converter”—making this an essential math skill.
Alternative Methods:
- If Total Marks Differ per Subject:
- Add all obtained marks, divide by total possible marks, then multiply by 100.
- Example: Scored 85, 92, 78 out of 100, 100, 150 →
Total Obtained = 85 + 92 + 78 = 255
Total Marks = 100 + 100 + 150 = 350
Percentage = (255 ÷ 350) × 100 ≈ 72.86%
- Using Decimals:
- Convert fraction to decimal first, then multiply by 100.
- Example: 47 out of 80 → (47 ÷ 80) = 0.5875 → 0.5875 × 100 = 58.75%
