Formula and How It Works
The Marks Percentage Calculator uses the universal percentage formula accepted by all examination boards worldwide. Here is how the math works:
- Obtained Marks
- The marks you actually scored in the exam or across all subjects combined.
- Total Marks
- The maximum possible marks for the exam or the sum of maximum marks across all subjects.
- Percentage
- The result expressed as a value out of 100, showing your relative performance.
- GPA (10-point scale)
- Calculated as Percentage Ãˇ 9.5, which is a widely used conversion in Indian universities.
For multiple subjects, the calculator sums all obtained marks and all total marks first, then applies the formula to the totals. This gives the correct weighted overall percentage.
