How marks are converted to a percentage
The formula is the same regardless of how many subjects you have or how different the maximums are. Add the marks obtained in every subject, add the maximum marks for every subject, then divide the first total by the second and multiply by 100.
Formula: Percentage = (Total Marks Obtained ÷ Total Maximum Marks) × 100
Step-by-step example
A five-subject result with mixed maximums:
| Subject | Marks obtained | Maximum marks |
|---|---|---|
| English | 78 | 100 |
| Mathematics | 92 | 100 |
| Science | 65 | 75 |
| Social Studies | 55 | 75 |
| Urdu | 83 | 100 |
| Total | 373 | 450 |
Percentage = (373 ÷ 450) × 100 = 82.9%, which falls in the B range on the standard US scale. Under most Pakistan board systems this is an A grade.
Understanding your result
The calculator shows a US letter grade alongside the percentage. Here is how the two scales compare:
| Percentage | US letter grade | Pakistan boards | Indian universities |
|---|---|---|---|
| 90 to 100 | A range | A1 | Distinction |
| 80 to 89 | B range | A | First Class |
| 70 to 79 | C range | B | Second Class |
| 60 to 69 | D | C | Pass |
| 50 to 59 | F (US) | D / Pass | Pass (some boards) |
| Below 50 | F | Fail | Fail |
Grade divisions vary by board and institution. Use the percentage figure as the universal reference when applying to different systems.
How to use this calculator
- Add a row for every subject on your result sheet.
- Enter the marks you received in the Marks column.
- Enter the maximum marks for that subject in the Out of column.
- Read the total marks, percentage, and letter grade in the result tiles below.
Subject names are optional. They help you keep track when entering a long result sheet, but the calculation does not need them.
When to use this calculator
Use it when a university application, scholarship form, or job portal asks for an overall percentage and your result sheet only shows marks per subject. It also works for internal tests and mid-term results that mix subjects with different total marks. For Pakistan board-specific calculations, the Matric Percentage Calculator and FSc Grade Calculator cover the BISE formula. For CBSE class X, use the CBSE CGPA to Percentage converter instead.
Common mistakes
Rounding marks before summing. Enter the raw marks exactly as they appear on your result sheet. Rounding each subject first and then adding introduces small errors that grow with more subjects.
Using the same maximum for every subject. Practical subjects, labs, and oral exams often carry different maximums. Set each row's Out of field to the actual maximum for that subject, not a blanket figure.
Including pass or fail subjects. Most boards exclude pass or fail items from the percentage calculation. Leave those rows out, or the total maximum will be inflated.
Separating theory and practical into two calculators. If your board reports theory and practical on the same result sheet as one subject, enter them as one row using the combined marks and maximum. If they appear as separate line items, enter them as two rows.
