GPA vs CGPA: What's the Difference?

GPA: one term

Your GPA (Grade Point Average) is the credit-weighted average of the grades in a single semester or term. It reflects how you did in that specific period only.

CGPA: the whole journey

Your CGPA (Cumulative Grade Point Average) is the credit-weighted average across every course you have taken so far. It is the number that appears on your transcript as your overall academic standing.

Some systems call this GPA as well, or use terms like "overall GPA" — but the idea is the same: cumulative across all terms.

How this semester updates your CGPA

To find your new CGPA, you combine your existing quality points with this semester's:

1. Existing quality points = current CGPA × completed credit hours.
2. Add this semester's quality points (grade points × credits for each new course).
3. Divide by the new total credits (completed + this semester's).

This is exactly what the GPAWorld calculator does automatically once you enter your current CGPA and completed credits — using your university's own rounding at each step.

How much can one semester move it?

Less than most people expect, and less every year. Your CGPA is weighted by every credit you have already completed, so a semester is only ever a fraction of the total:

• 15 credits added to 30 already completed is a third of your record — a strong term moves the number noticeably.
• 15 credits added to 90 is a seventh — the same term barely shifts it.
• A student at 3.00 after 90 credits who scores a perfect 4.00 over 15 credits finishes at 3.14, not 3.50.

This is the arithmetic behind the usual advice to protect your average early. It is far easier to hold a high CGPA from the start than to lift a low one later, because the credits already on your record cannot be re-weighted.

Quick comparison

• GPA — one semester; changes every term.
• CGPA — all semesters combined; moves more slowly as you accumulate credits.

Terminology varies more than the concept does. Some universities call the cumulative figure "overall GPA"; Indian institutions often use SGPA for the semester and CGPA for the cumulative; a few report only the cumulative number and never publish a per-semester one at all. Your university's page on GPAWorld uses whichever convention that institution actually publishes.
