How to Calculate Marks Percentage

To find your marks percentage, add all obtained marks and all maximum marks, then apply the formula below.

Formula

Marks Percentage = (Total Obtained Marks ÷ Total Maximum Marks) × 100

Steps

  1. List each subject and its maximum marks and obtained marks.
  2. Add all obtained marks. This is your total obtained.
  3. Add all maximum marks. This is your total maximum.
  4. Divide total obtained by total maximum.
  5. Multiply by 100 to get the percentage.

Example

Subject-wise: English 85/100, Math 90/100, Science 78/100, Social 88/100.

Total obtained = 85 + 90 + 78 + 88 = 341

Total maximum = 100 + 100 + 100 + 100 = 400

Percentage = (341 ÷ 400) × 100 = 85.25%

Marks percentage in Indian boards: state, CBSE, ICSE, university

The base formula is the same everywhere: percentage = (marks obtained ÷ maximum marks) × 100. What changes between boards is which subjects count toward the "official" aggregate. CBSE Class 10 lists best-of-five subjects (5 subjects out of the 5–6 the student appears in). Tamil Nadu State Board uses all six subjects. ICSE adds a separate internal/external split per subject. University degrees in India typically use SGPA per semester and CGPA across semesters, which then convert to percentage with a board- specific multiplier.

Always read the official mark sheet carefully — the number printed at the bottom is what colleges, scholarship portals, and government job portals (UPSC, SSC, banking) will accept. A self-calculated "higher" percentage will not be accepted in eligibility forms.

Worked examples by board

CBSE Class 10 best-of-five: 95+92+88+85+80
Total 440/500 → 88.0%
ICSE Class 10 (six subjects): 540/600
90.0% — all six count
B.Tech CGPA 8.4 (Anna University)
(8.4 − 0.5) × 10 = 79.0% per Anna Univ formula
B.Tech CGPA 8.4 (most other Indian univs)
8.4 × 9.5 = 79.8% per CBSE-style formula

Two universities can give two different percentages for the same CGPA. Always quote both the CGPA and the conversion formula your university officially uses when applying for higher studies abroad.
