Board results, college admissions and job forms often ask for your aggregate percentage. Enter the marks you obtained and the maximum marks for each subject to get an accurate overall percentage, even when subjects are marked out of different totals.
Enter marks obtained for each subject, separated by commas.
Enter the maximum marks for the same subjects.
Read your overall percentage.
Percentage: Percentage = (Σ marks obtained ÷ Σ maximum marks) × 100
The marks percentage calculator gives your aggregate percentage from subject-wise marks: total marks obtained divided by total maximum marks, times 100. It works even when subjects have different maximum marks, such as theory papers out of 80 and practicals out of 20 or 30.
Indian students need this number constantly: for college admission forms, for scholarship applications, for eligibility rules such as '50% in Class 12' and for comparing results across schools. Parents use it to read report cards, and teachers use it to prepare result sheets.
Enter marks obtained and maximum marks in the same order, and the calculator totals both columns and shows the percentage.
1. List every subject or paper that counts toward the aggregate under your board's rule.
2. Write marks obtained and maximum marks for each.
3. Add all marks obtained to get the total obtained.
4. Add all maximum marks to get the total maximum.
5. Compute percentage = total obtained ÷ total maximum × 100.
6. Round as your institution asks, usually to two decimals, and do not round up to cross a cut-off.
Aggregate percentage treats every mark equally. Averaging subject percentages instead treats every subject equally, whatever its maximum. These give the same answer only when all maxima are equal. If you score 27 out of 30 in a practical (90%) and 58 out of 100 in theory (58%), the average of percentages is 74%, but the aggregate is 85 out of 130, about 65.4%. The larger paper rightly carries more weight in the aggregate, which is what boards and universities use.
Boards and admission bodies have rules on which subjects count. Some use all subjects, some the best five, and some require a language or exclude additional subjects. Internal assessment is often part of the subject's total, so a theory paper out of 80 plus internal marks out of 20 makes a subject out of 100. The formula does not change, but the choice of rows does. Always follow the rule written in the prospectus or notification you are applying under.
Some boards add grace or moderation marks before publishing results, and those are already in the printed marks. Eligibility rules usually apply to the exact percentage, so 59.99% does not meet a 60% requirement unless the rule explicitly allows rounding. When a form asks for percentage 'up to two decimals', truncate or round as instructed rather than choosing the direction that helps you.
Vikram's Class 12 marksheet shows 72, 65, 81 and 58 in four theory papers out of 80 each, 90 out of 100 in English, and 27 out of 30 in a practical. He needs his aggregate for an admission form.
Total marks obtained: 72 + 65 + 81 + 58 + 90 + 27 = 393
Total maximum marks: 80 + 80 + 80 + 80 + 100 + 30 = 450
Percentage: 393 ÷ 450 × 100 = 87.33%
Answer: Overall percentage 87.33%; Marks 393 / 450
Averaging subject percentages when maximum marks differ.
Leaving out internal assessment marks that belong to a subject's total.
Including an additional subject when the rule counts only the main five.
Rounding 59.6% up to 60% to meet an eligibility cut-off.
Entering maximum marks in a different order from marks obtained.
Filling college and university admission forms.
Checking eligibility for scholarships and competitive exams with percentage cut-offs.
Teachers preparing class result sheets.
Comparing performance across terms when papers have different maximum marks.
Should I include additional or optional subjects?
Follow your board's rule. CBSE, for example, often uses the best five subjects for admission percentages.
Why is my average of subject percentages different?
Because subjects with larger maximum marks carry more weight in the true aggregate.
