GPA vs CGPA: What Students Should Know

GPA and CGPA answer different timeframes

Students often use GPA and CGPA as if they mean the same thing. In most academic systems they are related, but they cover different periods:

• GPA usually measures performance in one term or semester.
• CGPA combines results across multiple terms into a cumulative average.

Admissions offices, scholarship committees, and transfer evaluators often care about both: recent GPA for trajectory, and CGPA for overall consistency.

How a basic GPA is calculated

Each course grade is converted to grade points, then weighted by credit hours:

Example: A 3-credit A (4.0) and a 4-credit B (3.0):

((4.0 × 3) + (3.0 × 4)) ÷ (3 + 4) = 24 ÷ 7 ≈ 3.43

What “weighted” means

Weighted GPA gives more influence to courses with more credits. An A in a 4-credit lab matters more than an A in a 1-credit seminar. Some secondary schools also weight advanced courses higher than standard ones, so a school’s “weighted GPA” scale may go above 4.0.

How CGPA builds over time

CGPA is typically the credit-weighted average of all completed terms, not a simple average of semester GPAs. If one semester had fewer credits, it should not pull the cumulative result equally.

That is why improving one strong semester helps, but a heavy earlier load still remains in the cumulative record until more credits are earned.

CGPA to percentage conversions

Many universities publish their own conversion. A common approximation is:

Do not treat any single multiplier as universal. Always check your board, university, or employer guidelines before submitting converted marks.
