Use this free online marks calculator to add up marks obtained across multiple subjects and instantly find your total marks, overall percentage, and grade.
How to Use the Marks Calculator
Add a row for each subject, naming it and entering the marks obtained and maximum marks.
Click "Calculate Marks" to see your total marks, overall percentage, and grade.
How Total Marks and Percentage Are Calculated
The calculator adds the marks you obtained in every row, adds the maximum marks of every row, and divides one by the other: Overall Percentage = Total Obtained ÷ Total Maximum × 100. The percentage is rounded to two decimal places and then mapped to a grade.
Each row can have its own maximum, so you can mix a 100-mark paper with an 80-mark theory paper and a 20-mark practical. A subject with more marks carries more weight in the result, which is how boards and universities calculate an aggregate.
Worked Example: Class 12 Result
Suppose a student has six subjects, each out of 100, with marks of 78, 85, 92, 88, 74 and 66.
Total obtained = 483, total maximum = 600.
Overall percentage = 483 ÷ 600 × 100 = 80.50%, which falls in the A grade band on this page.
Some colleges and scholarships use the best five subjects instead. Remove the 66-mark row and the result becomes 417 ÷ 500 × 100 = 83.40%.
Grade Scale Used by This Calculator
Overall percentage
Grade shown
90% and above
A+
80% – 89.99%
A
70% – 79.99%
B+
60% – 69.99%
B
50% – 59.99%
C
40% – 49.99%
D
Below 40%
F
This is a general-purpose scale. Indian boards and universities each publish their own grading scheme, and some award grades by relative position in the class rather than fixed percentages, so treat the grade here as a rough label.
Points to Keep in Mind
Aggregate is not the same as the average of subject percentages when maximum marks differ. Scoring 45/50 (90%) and 120/200 (60%) gives an aggregate of 165/250 = 66%, not the 75% you get by averaging 90 and 60.
A good overall percentage does not guarantee a pass. Boards usually apply the pass mark to each subject separately (CBSE, for example, requires at least 33% in each subject), so check individual rows too.
Include grace or moderation marks only if they appear on your official mark sheet. Use the final marks after any revaluation when filling in an application.
If a subject is graded only (for example, a co-scholastic subject with no marks), leave it out, because it is not part of the aggregate.
Frequently Asked Questions
It adds up marks obtained across all subjects and divides by the total maximum marks across all subjects, then multiplies by 100.
The grade uses a common percentage scale: 90%+ = A+, 80-89% = A, 70-79% = B+, 60-69% = B, 50-59% = C, 40-49% = D, below 40% = F. Your institution's grading scale may differ.
Either add the two parts together in one row (for example 64 + 18 = 82 out of 80 + 20 = 100), or enter them as two rows. Both give the same overall percentage, because the calculator works with total marks.
Enter all your subjects, then remove the row with the lowest marks (or the subject your college excludes) and calculate again. Check the admission notice first, since some institutions require a particular language or core subject to be included in the five.
When subjects have different maximum marks, the overall percentage gives more weight to subjects with more marks. A simple average of percentages treats every subject equally. If every subject is out of the same maximum, the two methods give the same answer.
