Marks Percentage Overview
This calculator finds the percentage of marks you scored out of a total possible score — useful for exam results, test scores, or aggregating marks across multiple subjects for a board exam or semester result.

- Get your overall aggregate percentage across all subjects
- Useful for school, college, and competitive exam results
- Free and works on mobile or desktop
Calculation Formula
Percentage = (Marks Obtained ÷ Total Marks) × 100
Example: 420 out of 500 = 84%
Worked example: subject-wise marks percentage
You scored 78/100 in math, 64/80 in physics, and 42/50 in a lab practical.
- 1Add obtained marks: 78 + 64 + 42 = 184.
- 2Add total marks: 100 + 80 + 50 = 230.
- 3Divide obtained by total: 184 / 230 = 0.80.
- 4Multiply by 100 to get 80%.
This weighted-by-marks method is more accurate than averaging 78%, 80%, and 84%, because each subject has a different maximum mark value.
How this differs from percentage calculator
Marks percentage is built for exam scores and subject totals. The general percentage calculator is for everyday percent-of, increase, decrease, and reverse-percentage problems.
Common mistakes to avoid
- Do not average subject percentages when total marks differ.
- Do not enter grade points or CGPA in a marks calculator.
- Do not forget practical, lab, or internal-assessment marks if they appear in total marks.

Frequently Asked Questions
How is percentage different from a grade or GPA?
Percentage is a direct ratio of marks scored to marks possible; GPA and letter grades map ranges of percentages to point values or letters, and those mappings vary by institution.
Can this calculate percentage for board exam results with multiple subjects?
Yes — add each subject's marks and totals, and the calculator computes both individual and overall percentages.
Does this account for grace marks or moderation?
No — enter your final marks after any grace marks or moderation have already been applied by your board or institution.
What percentage is considered a good score?
This varies widely by country, institution, and exam — there's no universal cutoff, though many systems consider 60%+ satisfactory and 90%+ excellent.
Can this handle exams with negative marking?
Yes — simply enter your final net marks (after any deductions for wrong answers) as the 'marks obtained' value.
What is aggregate percentage?
Aggregate percentage is the overall percentage calculated by combining marks from all subjects or all years of a program, rather than looking at just one subject or one exam in isolation.
How do universities calculate percentage for merit lists?
Most universities calculate aggregate percentage using the same total-obtained-over-total-possible method shown here, though some apply subject-specific weighting or best-of-N subject rules — check your specific merit list criteria.
Should I include absent subjects?
Follow your official result rules. If the subject is counted in total marks, include it.
Can this calculate aggregate percentage?
Yes. Add all obtained marks and all maximum marks across subjects.
Why is aggregate different from average percentage?
Aggregate uses marks weight. Average percentage gives each subject equal weight even if maximum marks differ.
