🎓 How to Calculate Your CGPA (With Simple Examples)

CGPA (Cumulative Grade Point Average) is the average of the grade points you have earned across all your semesters, weighted by the credits of each subject. If the formula has ever confused you, this guide breaks it down into three simple steps.

The CGPA formula

CGPA = (sum of grade points × credits for each subject) ÷ (total credits). In other words, subjects with more credits count more toward your final average — which is exactly why a good grade in a heavy subject helps you more than the same grade in a light one.

Step-by-step example

Imagine one semester with three subjects: Maths (4 credits, grade point 9), Physics (3 credits, grade point 8), and English (2 credits, grade point 10).

• ▸Multiply each grade point by its credits: (9 × 4) + (8 × 3) + (10 × 2) = 36 + 24 + 20 = 80.
• ▸Add up the credits: 4 + 3 + 2 = 9.
• ▸Divide: 80 ÷ 9 = 8.89. Your CGPA is 8.89.

Converting CGPA to a percentage

Many Indian universities (and CBSE) use the rule: Percentage ≈ CGPA × 9.5. So a CGPA of 8.89 is roughly 84.5%. Always check your own institution's official conversion, as it can differ.
