When you need an overall school percentage
Almost every report card, scholarship application, and college admission form asks for an overall percentage. When subjects have different maximums (some out of 50, some out of 100), the calculation isn't just an average — it's a weighted sum with the maximums as weights. The school percentage calculator at allgradecalculator.com handles that correctly.
How to use it
- Add a row for each subject (or rename the default rows).
- Type your obtained marks.
- Type the maximum marks for that subject.
- Read the total marks, percentage, and letter grade.
Worked example
| Subject | Marks | Max |
|---|---|---|
| English | 78 | 100 |
| Math | 85 | 100 |
| Science | 72 | 100 |
| Social Studies | 80 | 100 |
| Computer (50-mark paper) | 42 | 50 |
| Total | 357 | 450 |
Percentage = 357 ÷ 450 × 100 ≈ 79.33%.
Tips
- Don't pre-convert each subject to a percentage — feed in the raw marks and let the calculator do one division at the end.
- Round only the final result. Rounding intermediate per-subject percentages introduces drift.
- For Pakistani BISE boards, use the dedicated matric percentage calculator with built-in BISE letter grades.
- For CBSE class X, use CBSE CGPA to percentage if your transcript shows CGPA rather than marks.
