Marks percentage calculator
Calculate your exam percentage and grade from marks across multiple subjects. Enter marks obtained and total marks per subject for an instant aggregate result.
What is the Marks Percentage Calculator?
This calculator is built for students in India who need to calculate their exam percentage from total marks. It supports grading scales from four major systems: CBSE (Central Board of Secondary Education), ICSE (Indian Certificate of Secondary Education), typical state board scales, and UGC-style university scales. You can enter your total marks obtained and total marks directly, or switch to subject-wise mode to enter marks for each subject individually.
The tool is most useful during board exam results season — whether you're checking your Class 10 or Class 12 CBSE results, calculating your semester percentage from a university marksheet, or figuring out how many marks you need for a specific grade. Subject-wise mode lets you enter each subject separately, which is helpful when subjects have different maximum marks (for example, theory and practical components scored out of 80 and 20). All calculations happen instantly in your browser.
How to calculate marks percentage
The formula is simple: percentage = (marks obtained ÷ total marks) × 100. For example, if you scored 425 out of 500: (425 ÷ 500) × 100 = 85.00%. For subject-wise calculation, add all marks obtained across subjects and divide by the total of all maximum marks. If you scored 82/100 in English, 78/100 in Hindi, 95/100 in Mathematics, 88/100 in Science, and 82/100 in Social Studies: (425 ÷ 500) × 100 = 85.00%.
CBSE grading scale
CBSE uses a letter grade system from A1 (highest, 91% and above) to E (fail, below 33%). The pass mark is 33%. Grades A1 and A2 are considered distinction and first class respectively. For Class 10, CBSE also has a best-of-5 rule where only the five highest-scoring subjects count toward the overall percentage — this calculator sums all entered subjects equally, so if you want the best-of-5 result, enter only those five subjects in subject-wise mode.
Percentage to CGPA conversion
The CBSE standard formula for converting percentage to CGPA is: CGPA = percentage ÷ 9.5. For example, 85% ÷ 9.5 = 8.95 CGPA. The inverse formula (CGPA to percentage) is percentage = CGPA × 9.5. Note that different universities use different conversion factors — Anna University uses percentage = (CGPA − 0.75) × 10, while VTU and other state universities have their own formulas. This calculator uses the CBSE formula as a reference.

FAQ
How do I calculate my marks percentage?
Divide your marks obtained by the total marks, then multiply by 100. For example, 425 out of 500 gives (425 ÷ 500) × 100 = 85%. You can also enter marks per subject and the calculator will sum them automatically.
What is the CBSE best-of-5 rule?
For Class 10, CBSE calculates the overall percentage using only the five subjects where you scored the highest. This means if you have six subjects, the lowest-scoring one is dropped. To use this rule with the calculator, enter only your five best subjects in subject-wise mode.
How to convert CBSE percentage to CGPA?
Divide the percentage by 9.5. For example, 85% ÷ 9.5 = 8.95 CGPA. This is the standard CBSE conversion formula. To convert back, multiply CGPA by 9.5.
Is 85% a good percentage in CBSE?
Yes. Under the CBSE grading scale, 85% falls in the A2 grade (81–90%), which is classified as First Class. It corresponds to approximately 8.95 CGPA. Most competitive exams and university admissions consider 85%+ as a strong result.
Does the marks percentage calculator store my data?
No. All calculations run entirely in your browser. Your marks are never sent to a server or stored after you close the page.
How do I calculate overall percentage from multiple subjects?
Add each subject's obtained marks and total marks using the + Subject button. The calculator sums all marks and divides by the total possible marks to give you the overall aggregate percentage.
