Student Percentage Calculator
Total marks to a percentage, across subjects with any maximums.
About this calculator
Add each subject with the marks you scored and the marks it was out of, and this gives your overall percentage: total obtained divided by total maximum. Subjects can have different maximums — a 100-mark theory paper alongside a 50-mark practical — and the totals account for that instead of assuming every paper is out of 100.
The average of the individual subject percentages is shown separately, because it is a different number whenever the maximums differ, and different boards use one or the other. Nothing you type is stored or sent anywhere.
Frequently asked questions
How do I calculate percentage of marks?
Divide the total marks you obtained by the total marks available and multiply by 100. Scoring 209 out of a possible 250 is (209 ÷ 250) × 100 = 83.6%.
How do I calculate percentage when subjects are out of different totals?
Sum the marks obtained and sum the maximums separately, then divide. 88/100, 76/100 and 45/50 gives 209 obtained out of 250 available, which is 83.6%. Averaging the three subject percentages instead would give 84.67% — a different figure, which is why both are shown.
Does this calculator give a grade or a CGPA?
No, deliberately. Grade boundaries, pass marks and GPA scales differ by board, country and year, and a calculator that guessed at them would be wrong for most people using it. This does the arithmetic every board agrees on and leaves the grading to your own mark sheet.
Can I add more than five subjects?
Yes — use the Add subject button for as many papers as you need, and remove any rows you do not. Empty rows are ignored rather than counted as zeros, so a half-filled form will not drag your percentage down.
