How to Calculate Matric and Inter Percentage from Marks (Formula and Chart)
To find your percentage, divide your obtained marks by the total marks and multiply by 100. For example, 900 marks out of 1100 is 900 ÷ 1100 × 100 = 81.82%. The same simple formula works for matric, inter, FSc, ICS, F.A, A-Level and any other exam.
Below you will find worked examples, a ready-made chart for the common totals of 1100 and 1200, a reverse method to find the marks you need for a target percentage, and the mistakes to avoid when you use your percentage in an admission form.
The Percentage Formula
Percentage = (Obtained marks ÷ Total marks) × 100
Use the total of the exam as printed on your result card. Many boards use 1100 as the total for matric and for inter, while others use 1200 or different totals depending on the group and the year. Never assume the total; always read it from your own marksheet.
How to Calculate Matric Percentage
Matric result cards usually show the marks of Class 9 and Class 10 together, with a combined total. Add the obtained marks of both parts, then divide by the combined total.
Example
A student gets 450 marks in Class 9 and 420 marks in Class 10. The total of both classes is 1100.
- Add the marks: 450 + 420 = 870.
- Divide by the total: 870 ÷ 1100 = 0.7909.
- Multiply by 100: 0.7909 × 100 = 79.09%.
How to Calculate Inter (FSc / FA / ICS) Percentage
The method for inter is the same. Add Part 1 and Part 2 marks, then divide by the combined total. If your marksheet shows a single combined figure, use that directly.
Example
A student gets 470 marks in Part 1 and 441 marks in Part 2, out of a combined 1100. The sum is 911, and 911 ÷ 1100 × 100 = 82.82%.

How Many Marks Do You Need for a Target Percentage?
Sometimes you know the percentage you want and need the marks. Multiply the total by the percentage and divide by 100.
Marks needed = Total marks × Target percentage ÷ 100
| Target percentage | Marks out of 1100 | Marks out of 1200 |
| 90% | 990 | 1080 |
| 80% | 880 | 960 |
| 70% | 770 | 840 |
| 60% | 660 | 720 |
| 50% | 550 | 600 |

Common Mistakes to Avoid
- Using the wrong total. A different total, such as 1200 instead of 1100, changes the percentage a lot.
- Counting only one part. For matric and inter, add both parts before dividing.
- Rounding too early. Keep two decimal places until the final answer.
- Mixing percentage with grade or GPA. A grade such as A+ is not a percentage. Admission forms usually ask for the exact marks.
- Ignoring the official figure. If your board or university publishes its own percentage on your result, that number is the one to trust.
