How to Calculate Percentage of Marks (Exams, Matric, Inter & University)
Board results, admission forms and job applications all ask for your percentage. Here is the one formula behind it, worked examples for every common situation — single exams, all subjects, Matric and Inter, grace and practical marks, CGPA and weighted aggregates — and the mistakes that cost students marks on forms.
Percentage of marks = (marks obtained ÷ total marks) × 100. For example, 945 out of 1100 = 945 ÷ 1100 × 100 = 85.91%. Always add the marks of every subject first and divide by the combined total — never average the subject percentages when subjects carry different total marks. To convert a CGPA, use your board’s or university’s own formula, such as CGPA × 9.5 for CBSE.
The percentage of marks formula
Percentage = (Marks obtained ÷ Total marks) × 100
- Add up the marks you obtained in every subject that counts.
- Add up the maximum marks for the same subjects.
- Divide obtained by total.
- Multiply by 100 and round to two decimal places.
Example 1: one exam or one subject
You scored 68 out of 75 in a test: 68 ÷ 75 = 0.9067 → × 100 = 90.67%.
For multiple-choice tests, the test grade calculator shows the percentage and letter grade for every possible number of wrong answers.
Example 2: all subjects (total percentage)
| Subject | Marks obtained | Total marks |
|---|---|---|
| English | 82 | 100 |
| Urdu | 78 | 100 |
| Mathematics | 95 | 100 |
| Physics (theory + practical) | 88 | 100 |
| Chemistry (theory + practical) | 84 | 100 |
| Biology | 90 | 100 |
| Total | 517 | 600 |
Percentage = 517 ÷ 600 × 100 = 86.17%.
Example 3: Matric or Inter result out of 1100
Board results print your total marks obtained and the total marks for the whole exam. If your result card shows 945 out of 1100:
945 ÷ 1100 × 100 = 85.91%
If your board’s total is different (for example 1200 for some recent schemes), use the total printed on your result card — the formula never changes.
Example 4: subjects with different total marks
This is where most students go wrong:
| Subject | Marks | Out of | Subject % |
|---|---|---|---|
| Mathematics | 140 | 150 | 93.3% |
| Computer Science | 40 | 75 | 53.3% |
| Total | 180 | 225 | — |
- ✅ Correct: 180 ÷ 225 × 100 = 80.00%
- ❌ Wrong: average of 93.3% and 53.3% = 73.3%
Averaging percentages gives every subject equal weight, even though Mathematics is worth twice as many marks. Always divide total obtained by total maximum.
Example 5: weighted aggregate (admissions)
Admission merit is often a weighted aggregate, not a simple percentage. For medical colleges in Pakistan, our MDCAT aggregate calculator uses MDCAT 50%, FSc 40% and Matric 10%. For example, MDCAT 170/180, FSc 1050/1100 and Matric 1080/1100 give:
(170 ÷ 180 × 50) + (1050 ÷ 1100 × 40) + (1080 ÷ 1100 × 10) = 47.22 + 38.18 + 9.82 = 95.22%
Each component is first turned into a percentage, then multiplied by its weight. Always check the weights in the current year’s admission policy.
How to convert CGPA to percentage (and percentage to CGPA)
There is no single formula — use the one your board or university publishes:
| Rule | CGPA → percentage | Percentage → CGPA |
|---|---|---|
| CBSE (Class 10) | CGPA × 9.5 | Percentage ÷ 9.5 |
| Many Indian universities | CGPA × 10 | Percentage ÷ 10 |
| Some universities (e.g. VTU) | (CGPA − 0.75) × 10 | Percentage ÷ 10 + 0.75 |
Example: 8.4 CGPA × 9.5 = 79.8% (CBSE), and 85% ÷ 9.5 = 8.95 CGPA. For 4.0-scale CGPAs (Pakistan, the US), most universities do not define a percentage; request an official equivalence certificate if a form insists.

Percentage vs percentile
They are not the same:
- Percentage is your own score out of 100.
- Percentile is the share of test-takers who scored below you. A 90th percentile means you beat 90% of candidates, even if your percentage was 70%.
Entrance tests and merit lists often report percentiles or ranks; your board result reports a percentage.
Rounding and form-filling tips
- Round only at the end, normally to two decimal places (85.909 → 85.91%).
- Don’t round up across a cut-off. 59.99% is not 60% unless the institution’s rule says so.
- Use the marks on the final result card, including improvement or supplementary results if your board has replaced the original marks.
- Include practical marks when they are part of the subject total on your result card.
- Check whether a form wants “percentage” or “aggregate” — they can be different numbers.
Quick conversions
| Marks | Out of 1100 | Out of 1200 | Out of 500 |
|---|---|---|---|
| 90% | 990 | 1080 | 450 |
| 85% | 935 | 1020 | 425 |
| 80% | 880 | 960 | 400 |
| 75% | 825 | 900 | 375 |
| 70% | 770 | 840 | 350 |
| 60% | 660 | 720 | 300 |
To find the marks for a target percentage: marks needed = target % × total marks ÷ 100. Need the score for a target grade in one class? Use the grade converter or, for semester GPAs in Pakistan, the Pakistan GPA & CGPA calculator.
Frequently asked questions
How do I calculate the percentage of my marks?
Divide the marks you obtained by the total marks and multiply by 100. For example, 945 out of 1100 is 945 ÷ 1100 × 100 = 85.91%.
How do I calculate percentage of marks for all subjects?
Add the marks obtained in every subject, add the maximum marks of the same subjects, divide the first total by the second and multiply by 100. Do not average the subject percentages.
How do I calculate Matric percentage?
Divide the total marks on your result card by the total marks of the exam (for example 1100) and multiply by 100. 980 out of 1100 is 89.09%.
How do I convert percentage to CGPA?
Reverse your board’s formula. For CBSE, CGPA = percentage ÷ 9.5, so 85% equals 8.95. Many universities use percentage ÷ 10. Always use the formula on your marksheet.
Is percentage the same as percentile?
No. Percentage is your score out of 100; percentile is the share of candidates who scored below you.
How many marks do I need for 80% out of 1100?
80% of 1100 is 880 marks. Use marks needed = target percentage × total marks ÷ 100.
Sources and methodology
All examples use the standard percentage formula and are rounded to two decimal places. Board totals and admission weights vary by year and province; always use the figures printed on your own result card and in the current admission policy.
