Calculate overall percentage from multiple subject marks. Free aggregate percentage calculator for students. Add as many subjects as needed, enter marks obtained and total marks for each, and see your overall aggregate percentage with an Indian academic grade. Handles mixed totals (e.g., 100, 50, and 25) and lets you add or remove subjects dynamically.

How Aggregate Percentage Calculator Works
Aggregate percentage combines marks from several subjects — even ones scored out of different totals — into a single overall percentage. Instead of averaging each subject's percentage separately, this calculator pools every subject's obtained marks and every subject's total marks and divides one grand sum by the other.
Formula: Aggregate % = (Sum of Marks Obtained ÷ Sum of Total Marks) × 100, using only the rows where a total mark has been entered. The result also maps to a grade band: A+ ≥ 90%, A ≥ 80%, B+ ≥ 70%, B ≥ 60%, C ≥ 50%, D ≥ 40%, otherwise F.
- Subject — an optional label identifying each subject or course row you add
- Marks Obtained — the score you achieved in that subject
- Total Marks — the maximum possible marks for that subject (rows left at zero are excluded from the sum)
- Aggregate % — the combined percentage across all subjects with a total entered
- Grade — the letter grade band the aggregate percentage falls into
Example Scenarios
| Subjects (Obtained / Total) | Sum Obtained / Sum Total | Aggregate % (Grade) |
|---|---|---|
| Math 85/100, Science 72/100, English 90/100 | 247 / 300 | 82.33% (A) |
| Physics 45/50, Chemistry 18/25, Math 88/100 | 151 / 175 | 86.29% (A) |
| Hindi 60/100, Math 55/100 | 115 / 200 | 57.50% (C) |
| Science 38/50, Math 30/50 | 68 / 100 | 68.00% (B) |
| English 95/100, Math 92/100, Science 98/100 | 285 / 300 | 95.00% (A+) |
| Subject 1: 20/50, Subject 2: 15/50 | 35 / 100 | 35.00% (F) |
Common Mistakes with an Aggregate Percentage Calculator
An aggregate percentage calculator divides total marks obtained by total maximum marks. That is not the same as averaging each subject's percentage when totals differ.
Take 90 out of 100 and 10 out of 25. Averaging 90% and 40% gives 65%, but the aggregate percentage calculator returns 100 out of 125, or 80%, because the larger paper carries more weight.
- Enter the right maximum for each paper, including practicals or internals if your board adds them.
- Check which subjects count. Some boards and admission forms use a best-of-five rule or exclude additional subjects, so enter only those in the aggregate percentage calculator.
- Don't round each subject first; small roundings add up.
The grade band from the aggregate percentage calculator is a general guide. Universities and employers may apply their own formula or CGPA conversion, so check the rules in the notice you are applying to before quoting the aggregate percentage calculator figure. The weighted arithmetic mean article on Wikipedia explains why the two methods differ.
Aggregate Percentage Calculator FAQ
How is aggregate percentage different from averaging each subject's percentage?
Averaging percentages treats every subject equally regardless of its total marks, while aggregate percentage pools the actual obtained and total marks first. A subject worth 100 marks influences the aggregate more than one worth 25 marks, which better reflects overall performance.Can I use this when subjects have different maximum marks, like 100 and 50?
Yes. That's the main reason this calculator exists — it sums the obtained marks and total marks across all rows regardless of each subject's individual maximum, so mixed totals like 100, 50, and 25 are handled correctly.What Indian academic grade corresponds to my aggregate percentage?
This calculator uses a common Indian grading scale: A+ for 90% and above, A for 80-89%, B+ for 70-79%, B for 60-69%, C for 50-59%, D for 40-49%, and F below 40%. Your institution's exact grade boundaries may differ slightly.What happens if I leave a subject's total marks blank or at zero?
Rows without a total marks value greater than zero are excluded from both the obtained and total sums, so an incomplete row won't skew your aggregate percentage. Only fill in subjects you want counted.How many subjects can I add to the calculator?
The calculator starts with three rows and lets you add as many additional subject rows as you need using the "Add Row" button, or remove any row you don't need with its delete button.Is aggregate percentage the same thing as CGPA?
No. Aggregate percentage is a straight ratio of marks obtained to marks possible, while CGPA (Cumulative Grade Point Average) uses a points-based scale that many universities convert from percentage using their own institution-specific formula.Related Calculators
For a quick single-subject calculation, the general percentage calculator handles one obtained-over-total figure at a time. If your subjects should count differently toward a final grade (for example, exams weighted more than assignments), the weighted average calculator is a better fit, while the plain average calculator is useful for simple unweighted number sets.
