Calculating the percentage of marks is a fundamental mathematical process used globally in education systems. Whether you are a student evaluating your performance or a teacher grading papers, understanding the marks percentage formula is essential.

The Standard Formula

Percentage = (Obtained Marks ÷ Total Marks) × 100

Step-by-Step Guide

  2. Identify Total Marks: This is the maximum absolute score possible for the test (e.g., 50).
  3. Divide: Divide the obtained marks by the total marks (45 ÷ 50 = 0.9).
  4. Multiply: Multiply the result by 100 to get the percentage value (0.9 × 100 = 90%).
