Grade percentage is calculated by dividing obtained marks by total marks and multiplying the result by 100. This gives your score as a percentage out of 100.
Example: If you got 85 marks out of 100, your grade percentage is 85 ÷ 100 × 100 = 85%.
This calculator uses a common grading scale. Your school, college, or teacher may use a different grade scale, so always follow your official grading policy when needed.

| Type | Meaning | Example |
|---|---|---|
| Obtained Marks | The marks you earned. | 42 out of 50 |
| Total Marks | The maximum possible marks. | 50 total marks |
| Percentage | Your score converted out of 100. | 84% |
| Letter Grade | A grade based on percentage range. | B |
