Calculators
Marks Percentage Calculator
Add your subjects to get your overall percentage, count only the best few if your admission rules allow it, and combine weighted components.
Marks by subject
Enter marks obtained and maximum marks (obtained no more than the maximum) for at least one subject.
Weighted components (internal and external)
Use this when parts are scaled, e.g. internals out of 50 that count for 20% and a theory paper out of 100 that counts for 80%. Result = Σ weight × (obtained ÷ out of) ÷ Σ weight.
Enter obtained marks, maximum marks and a weight above zero for at least one component.
Your grade scale
Each row is the lowest percentage for that grade. Replace these with your board’s or university’s table. The starting rows are the 10-point table printed in VTU’s 2022 regulations (22OB 6.1) and the University of Mumbai’s NEP 2020 circular (Table 4.3); other institutions use different tables.
Best-of-N rules differ between boards and admitting institutions. CBSE does not award an aggregate: its notice of 30 November 2023 says the admitting institution or employer decides which best five subjects to use and does any percentage calculation.

Frequently asked questions
How do I calculate the percentage of my marks?
Add the marks you obtained in every subject, divide by the total maximum marks and multiply by 100. Scoring 412 out of 500 across five subjects gives 412 ÷ 500 × 100 = 82.4%. The calculator does this for any number of subjects, including ones with different maximum marks.
Should I total the marks or average the subject percentages?
They give the same answer only when every subject has the same maximum. With 45 out of 50 (90%) and 60 out of 100 (60%), the total is 105 out of 150, or 70%, while the average of the two percentages is 75%. This calculator uses totals, the usual meaning of an aggregate, but check which method your institution asks for.
How does the best-of-five calculation work?
Only the chosen number of subjects is counted. Any subject you mark as “always count” goes in first, then the remaining subjects with the highest percentages fill the rest. CBSE’s notice of 30 November 2023 says the Board does not award an aggregate, and that the admitting institution or employer decides which best five subjects to take, so follow that institution’s rules on which subjects qualify.
How do I combine internal and external marks?
If the parts already add up to the subject total, such as 20 internal plus 80 external out of 100, just add them. If they are scaled, use the weighted section: each part counts as weight × obtained ÷ maximum. Internals of 40 out of 50 weighted 20% give 16, a theory paper of 60 out of 100 weighted 80% gives 48, and together that is 64%.
Which grading scale does the calculator use?
Whichever one you enter. It starts with the 10-point table printed in VTU’s 2022 B.E./B.Tech regulations and the University of Mumbai’s NEP 2020 circular (O from 90%, A+ from 80%, down to P from 40%), but every row can be edited, added or removed. Boards and universities use different tables, so replace it with your own.
Are my marks stored or uploaded?
No. Everything is calculated in your browser, and nothing you type is sent to a server or saved. Reloading the page resets the tables.
About this tool
This marks percentage calculator turns a set of subject marks into the percentage figures that admission forms and applications ask for. Enter marks obtained and maximum marks for each subject, and it shows each subject’s percentage, the overall aggregate and the working behind it. Subjects can have different maximum marks, since the aggregate is total obtained ÷ total maximum × 100.
Many admission rules count only some subjects, such as the best five or the best four including a language. Tick “Count only the best”, choose the number and mark any subjects that must always count. The remaining places go to your strongest subjects, ranked by percentage so that a paper out of 50 is compared fairly with one out of 100, and subjects left out are faded so you can see exactly which ones were used. CBSE’s notice of 30 November 2023 says the Board does not award an aggregate and leaves any best-five calculation to the admitting institution or employer, so check that institution’s own rules.
The weighted section handles subjects whose parts are scaled, such as internal assessment and an external exam. Each component contributes its weight × obtained ÷ maximum, and the calculator lists every contribution so they visibly add up to the result. If your weights do not add up to 100, each is treated as a share of their total and the calculator tells you so.
Grades are shown against a scale you control. The starting rows are the 10-point table from VTU’s 2022 regulations and the University of Mumbai’s NEP 2020 circular, both linked on the page, but there is no single national table, so edit the rows to match your own board or university. All calculations stay in your browser.
