How to Calculate Marks and Percentage

Percentage Formula:

Percentage = (Total Marks ÷ Maximum Marks) × 100

Example:
If the maximum marks per subject are 100 and you have 3 subjects:

Maximum Marks = 100 × 3 = 300
Percentage = (245 ÷ 300) × 100 = 81.67%

Grade Calculation

Grades are usually assigned based on percentage ranges. A common grading system is:

• 90% and above – A+
• 80% to 89% – A
• 70% to 79% – B
• 60% to 69% – C
• 50% to 59% – D
• Below 50% – F

Pass or Fail Criteria

Most educational institutions consider 40% as the minimum passing percentage. If your percentage is equal to or above this threshold, you are marked as Pass; otherwise, the result is Fail.

Common Mistakes Students Make

• Forgetting to calculate total maximum marks correctly
• Using wrong percentage formula
• Ignoring subject-wise maximum marks
• Rounding off marks too early

Using an online calculator avoids these mistakes and ensures accurate results.
