How do I calculate the percentage of marks?
Divide the obtained marks by the total marks and multiply by 100. For example, 412 out of 500 is 412 ÷ 500 × 100 = 82.4%. On the Pakistani board scale 82.4% is grade A1; the pass mark on boards is 33%, and many schools use 40%.

What is the formula for percentage of marks?
Percentage = (obtained marks ÷ total marks) × 100.
Example 1: 385 out of 550 → 385 ÷ 550 = 0.7, × 100 = 70%.
Example 2: 1,020 out of 1,100 (Matric) → 1,020 ÷ 1,100 = 0.9273, × 100 = 92.73%.
For several subjects, add all obtained marks and all total marks first, then use the same formula. Do not average the subject percentages if the subjects have different total marks — that gives the wrong answer.
What grade is my percentage in Pakistan?
Pakistani boards (BISE) give A1 from 80%, A from 70%, B from 60%, C from 50%, D from 40% and E from 33%. Below 33% is fail.
Schools set their own scale, so check your school’s policy. Switch the calculator between the board scale and the school scale to see both.
| Percentage | Board grade | Common school grade |
|---|---|---|
| 80% and above | A1 | A+ |
| 70% – 79% | A | A |
| 60% – 69% | B | B |
| 50% – 59% | C | C |
| 40% – 49% | D | D |
| 33% – 39% | E | F (fail at 40%) |
| Below 33% | F (fail) | F (fail) |
How many marks do I need for a target percentage?
Multiply the target percentage by the total marks and divide by 100, then round up. For 80% in 1,100 marks: 80 × 1,100 ÷ 100 = 880 marks.
Use the “Marks needed” mode to work this out for any target, such as the 33% passing marks in a 75-mark paper (25 marks).
