How to calculate percentage of marks
Updated: 28 October 2026
Your marks percentage tells you what share of the total marks you scored. Add up the marks you got, add up the maximum marks, divide and multiply by 100.
Worked example: Class 10 marksheet
| Subject | Marks obtained | Maximum |
|---|---|---|
| English | 84 | 100 |
| Hindi | 78 | 100 |
| Mathematics | 92 | 100 |
| Science | 88 | 100 |
| Social Science | 83 | 100 |
| Total | 425 | 500 |
Percentage = 425 ÷ 500 × 100 = 85%.
When subjects have different maximum marks
Practicals, internal assessment or college papers are often out of 50, 75 or 150. Add every mark obtained and every maximum mark separately, then divide. For example, 45/50 + 90/150 + 70/100 = 205/300 = 68.33%. Averaging the three subject percentages (90%, 60% and 70%) would give 73.33%, which is wrong, because the 150-mark paper carries more weight. Always use the totals.
Marks needed for a target percentage
To reach 75% in a 500-mark exam, you need 500 × 75 ÷ 100 = 375 marks. Enter a target above and the calculator shows how many more marks you need, or how far ahead you are.
Percentage to division
| Percentage | Division (common rule) |
|---|---|
| 75% and above | First Division with Distinction |
| 60% to 74.99% | First Division |
| 45% to 59.99% | Second Division |
| 33% to 44.99% | Third Division / Pass |
| Below 33% | Below pass mark |
These bands are widely used in India, but boards and universities differ (some use 35% or 40% as the pass mark). Your marksheet's own rule is final.
Frequently Asked Questions
How do I calculate percentage of marks?
Add the marks you scored in all subjects, divide by the total maximum marks and multiply by 100. For example, 425 out of 500 is 425 ÷ 500 × 100 = 85%.
How do I calculate percentage when subjects have different maximum marks?
Add all marks obtained and add all maximum marks separately, then divide the first total by the second. Do not average the subject percentages, because that gives the wrong answer when maximum marks differ.
How do I calculate 10th or 12th percentage?
Enter the marks of the subjects your board counts. For all subjects, use this calculator. CBSE often uses the best five subjects, and ICSE and ISC have their own best-of rules with ICSE and ISC calculators on EzyCalc.
What percentage is first division?
Most Indian boards and universities treat 60% and above as first division, 45% to 59% as second division and 33% to 44% as third division or pass. Some use 75% for distinction. Check your own board rules.
How many marks do I need for a target percentage?
Multiply the total maximum marks by your target percentage and divide by 100. For 75% of 500, you need 375 marks. The calculator shows this when you enter a target.
