Calculate Percentage of Marks Obtained
To find out how much percent you scored in your exam, you need to follow the following formula.
- First of all, calculate the total marks you obtained or scored in your subjects by adding every single subject’s marks.
- Then, calculate the total marks for all the subjects by adding up their maximum marks(M.M.).
- Now, divide the obtained marks with the total maximum marks.
- Multiply the result with 100 to get a percentage of your marks.
For example, a student scored the following marks in his exams.
| Subject | Obtained or Scored Marks | Maximum Marks |
| Subject 1 | 57 | 80 |
| Subject 2 | 89 | 100 |
| Subject 3 | 97 | 100 |
| Subject 4 | 65 | 80 |
| Subject 5 | 63 | 80 |
| Subject 6 | 73 | 80 |
| Total | 444 (Total scored marks) | 520 (Total maximum marks) |
Now, to calculate the percentage follow the below formula
= Total scored marks × 100
Total maximum marks
= 444 × 100 = 85.38
520
Therefore, the above student scored 85.38% in his exams.
