Percentage from marks for one exam or every subject, with best of five and pass marks
Runs in your browser. Nothing you type is sent anywhere. Checked against sources on 30 Oct 2026.Percentage of marks is the marks obtained divided by the maximum marks, times 100. Six subjects scoring 519 out of 600 give 86.5%; dropping the lowest, 78, leaves 441 out of 500, or 88.2% over the best five. CBSE's pass mark is 33% in each subject.
Rates and rules read from the sources listed on this page (the earliest on 30 Oct 2026); they may have changed since.
Under "Your marks", type each subject with its "Marks obtained" and "Maximum marks", using "Add a subject" for more rows.
Choose "All subjects" or "Best five" under "Subjects counted".
Set the "Pass mark per subject", the "Target percentage" and, if exams remain, "Exams still to come, max marks".
Read the "Percentage" and the "Subject by subject" table, then press "Share result" to copy a link.
The Marks Percentage Calculator turns marks into a percentage for a single exam or a whole marksheet. Enter each subject with its name, the marks you scored and the maximum marks, and the page shows the overall percentage, each subject's percentage, whether each subject clears the pass mark, and how many more marks a target percentage would need.
The formula is marks obtained divided by maximum marks, multiplied by 100. With several subjects the marks are added first and then divided by the added maximums, which is not the same as averaging the subject percentages when the papers carry different maximums. A 45 out of 50 and a 60 out of 100 make 105 out of 150, which is 70%, not the 75% an average of 90% and 60% would suggest.
Best of five. CBSE does not calculate a percentage. Its notice of 30 November 2023 says the Board does not calculate or declare one, and that when a candidate offered more than five subjects the admitting institution or employer decides which five count. Switch on best of five and the page counts the five highest subject percentages, shows which subject was dropped, and keeps the all-subject figure beside it. Some institutions fix a subject, such as a language, into the five, so check the admission rules.
Pass mark. The CBSE Examination Bye-Laws set the pass mark at 33% in each subject. That is the default here and an editable box, because state boards, universities and school tests set their own. The check is on the subject total. It does not test Class XII's separate 33% in theory and in practical.
Target. Enter a target percentage to see the marks it needs, rounded up to a whole mark, and the gap from what you have. If exams are still to come, enter their maximum marks to see the percentage you need in them.
The page does not convert grades or CGPA; use the CGPA to Percentage calculator for that. Nothing you type leaves your browser.
Divide the marks obtained by the maximum marks and multiply by 100. For several subjects, add all the marks obtained, add all the maximum marks, and divide the first total by the second. Six papers scoring 519 out of 600 give 519 divided by 600, times 100, which is 86.5%.
Take the five subjects with the highest marks, add their marks and divide by 500. CBSE itself does not calculate a percentage: its notice of 30 November 2023 leaves the choice of five subjects to the admitting institution or employer, and some require a language among the five, so check their rule.
The CBSE Examination Bye-Laws set the pass mark at 33% in each subject. In Class X the theory and internal assessment marks are combined; in Class XII a subject with practical work needs 33% in theory and in practical separately. The page checks the subject total only, and the pass mark is editable.
Only when every paper has the same maximum marks. A 45 out of 50 and a 60 out of 100 average to 75%, but together they are 105 out of 150, which is 70%. Adding the marks first is the correct method, and it is what this page does.
Multiply the total maximum marks by 0.9 and round up to a whole mark. Out of 500 that is 450; out of 600 it is 540. Enter a target and the page shows the marks needed and the gap, or, with exams still to come, the percentage required in those papers.
Only if the college counts the same subjects. Admission rules differ on best of five, compulsory subjects and whether additional subjects count, and a few colleges round differently. Treat this as a check of the arithmetic, and follow the admission notice where it says how the percentage is worked out.
