Marks Percentage Calculator

How to Calculate Marks Percentage

To find your overall percentage across one or more subjects, add up the marks you obtained in every subject and divide by the total maximum marks possible, then multiply by 100. This works whether you're calculating a single test's percentage or a combined percentage across an entire report card.

Add a row for every subject with the marks you scored and the maximum marks for that subject, then read off your combined percentage and approximate grade band below.

Example

A student scores 85/100 in one subject, 72/100 in another, and 91/100 in a third. Total obtained is 248 out of a total maximum of 300, giving a percentage of (248 ÷ 300) × 100 = 82.67%.

Common Use Cases

FAQs

Is this the same as averaging each subject's percentage?

Only if every subject has the same maximum marks. When subjects have different maximum marks (e.g. one out of 100 and another out of 50), this calculator correctly weights by total marks rather than simply averaging each subject's individual percentage, which would distort the result.

What grading scale does the grade band use?

The grade band shown (A+ down to F) uses a common general-purpose scale: 90%+ is A+, 80-89% is A, 70-79% is B+, 60-69% is B, 50-59% is C, 40-49% is D, and below 40% is F. Your school or exam board may use a different scale, so treat this as a general reference rather than an official grade.

Can I use this for a single subject only?

Yes — remove the extra rows so only one remains, enter the marks obtained and maximum marks for that one subject, and the calculator will show that subject's individual percentage.
