Percentage calculator for marks

This percentage calculator for marks turns a marksheet into a percentage: type the marks of each subject, one per line, and it adds them up, divides by the maximum marks and shows the percentage with the working. It can also count only your best five (or four, or three) subjects.

Source: Wolfram MathWorld – Percent (a ratio expressed as a fraction of 100). Updated: .

Write the marks obtained, for example “English 78”. If a subject has different maximum marks, add them: “Physics 54 70” or “Physics 54/70”. The subject name is optional; if it ends in a number (“Paper 2”), write the marks as “Paper 2 78/100”.
Used for every line that does not state its own maximum. Usually 100; enter 80, 50 or 150 if your papers are marked out of that.

83% – 498 out of 600 marks (6 subjects)
Calculation
  • Marks obtained: 78 + 82 + 91 + 74 + 85 + 88 = 498
  • Maximum marks: 100 + 100 + 100 + 100 + 100 + 100 = 600
  • Percentage = marks obtained ÷ maximum marks × 100 = 498 ÷ 600 × 100 = 83%

Which subjects count – all of them, the best five, or English plus the best four – is decided by your board, college or the admission notice, not by the calculator.

How it is calculated

Percentage of marks = total marks obtained ÷ total maximum marks × 100. With 498 marks out of 600 the percentage is 498 ÷ 600 × 100 = 83%.

How to calculate the percentage of your marks

  1. Add up the marks you obtained in all subjects that count.
  2. Add up the maximum marks of the same subjects.
  3. Divide the first total by the second and multiply by 100.

Example: six subjects out of 100

Best of 5 percentage

Many colleges and application forms ask for the percentage of your best five subjects. Choose “Best 5 subjects” and the calculator keeps the five subjects with the highest percentage and leaves out the rest. In the example the lowest subject, Science with 74, is dropped: 78 + 82 + 91 + 85 + 88 = 424 out of 500, which is 84.8%.

Some rules are stricter – for example English must be included, or only academic subjects may be counted. In that case delete the lines that are not allowed and keep “All subjects”.

Subjects with different maximum marks

If theory is out of 70 and practicals out of 30, or one paper is out of 150, write the maximum after the marks: “Physics 54 70”. The calculator then divides the sum of all marks by the sum of all maximum marks. That is the correct percentage for a marksheet – it is not the same as averaging the subject percentages, because a paper out of 150 must weigh more than a paper out of 50.

Example: 54 out of 70 and 28 out of 30 give 82 out of 100 = 82%. The average of the two percentages (77.14% and 93.33%) would be 85.24% – and wrong.

Frequently asked questions

How do I calculate the percentage of marks?

Divide the total marks obtained by the total maximum marks and multiply by 100. Example: 498 out of 600 is 498 ÷ 600 × 100 = 83%.

How do I calculate the percentage for 5 subjects out of 500?

Add the marks of the five subjects and divide by 5 – with 100 marks per subject, 424 out of 500 is 84.8%.

How do I calculate the percentage for 6 subjects out of 600?

Add the six marks and divide by 6. Example: 498 out of 600 is 83%.

What is a best of 5 percentage?

The percentage of your five highest-scoring subjects only. Select “Best 5 subjects” and the lowest subjects are left out automatically. Check whether your college requires particular subjects to be included.

What if my subjects have different maximum marks?

Write the maximum after the marks on that line, for example “54 70”. The calculator divides total marks by total maximum marks.

Can I average the percentages of each subject instead?

Only if every subject has the same maximum marks. Otherwise the result is wrong, because larger papers must count more.

How do I convert a percentage back to marks?

Multiply the maximum marks by the percentage and divide by 100. 85% of 600 marks is 510 marks.

Does this work for semester marks in college?

Yes, for any marksheet in marks. If your university uses credits and grade points instead, use the SGPA and CGPA calculators linked above.
