What is CGPA and How is it Calculated?

CGPA stands for Cumulative Grade Point Average. It is a grading system used to measure a student's overall academic performance over a period of time. Instead of using percentages, a grade point (typically on a scale of 10) is used.

How it Works: The 9.5 Multiplier Rule

Many educational boards in India, most notably the Central Board of Secondary Education (CBSE), use a standard formula for converting between percentage and CGPA. This formula is based on the average marks of students who scored a perfect grade.

  • CGPA to Percentage: Percentage = CGPA × 9.5
  • Percentage to CGPA: CGPA = Percentage / 9.5

Our tool uses this widely accepted formula to ensure you get an accurate and representative conversion.

Frequently Asked Questions (FAQ)

Q1: Why is the number 9.5 used in the calculation?

Answer: According to CBSE, the number 9.5 was determined by taking the average marks of students who scored between 91 and 100 percent in previous years. This average turned out to be close to 95 percent, so a multiplier of 9.5 was established to provide a realistic conversion from a 10-point CGPA scale to a 100-point percentage scale.

Q2: Is this CGPA calculator applicable for all universities and boards?

Answer: While the 9.5 multiplier is very common (especially for CBSE schools), it is not universal. Some universities, colleges, or state boards may use a different formula or conversion scale (e.g., a 4-point GPA scale). Always check with your specific institution for their official conversion method if you need it for a formal application.

Q3: What's the difference between GPA and CGPA?

Answer: GPA (Grade Point Average) usually refers to your score for a single semester or academic year. CGPA (Cumulative Grade Point Average) is the average of all your GPAs from all semesters up to a certain point, giving a more holistic view of your academic performance.
