GPA vs CGPA: the core difference
GPA and CGPA are built from the same arithmetic, so the difference between them is about scope and scale, not method.
Scope: how much they cover
A GPA (Grade Point Average) can refer to a single term or to your whole record, depending on context. A CGPA (Cumulative GPA) always refers to the running total across every semester completed so far. In Indian universities you will often see SGPA for a single semester and CGPA for the cumulative figure — the relationship is that your CGPA is the credit-weighted combination of all your SGPAs.
Scale: the numbers they sit on
In US and Canadian systems, GPA is usually on a 4.0 scale. In India, CGPA is usually on a 10-point scale. So “a 3.6 GPA” and “an 8.4 CGPA” can describe similarly strong students on different scales. They are not interchangeable numbers, which is exactly why conversion tools exist.
When each is used
You will quote a semester GPA/SGPA when tracking term-by-term progress or planning what grades you still need. You will quote your CGPA on resumes, application forms, and transcripts, because it represents your complete performance.
To work with either, use the CGPA/GPA calculator — switch the scale selector to match your system. If you have several semester SGPAs and want the cumulative figure, the SGPA to CGPA calculator combines them with the correct credit weighting. And if an application asks for a percentage or a US GPA instead, see the CGPA to percentage and CGPA to US GPA tools.
A common point of confusion
Application forms rarely spell out which figure they want. “GPA” on an international form usually means a 4.0-scale number, while an Indian form asking for “GPA” almost always means your 10-point CGPA. When a form gives no scale, the safest move is to write the number and its maximum — for example “8.4/10” or “3.6/4.0” — so it can never be misread as the wrong scale.
Key takeaways
- GPA can mean one term or your whole record; CGPA is always cumulative.
- GPA usually sits on a 4.0 scale, CGPA on a 10-point scale — they are not the same number.
- Quote your CGPA (with its scale) on resumes and transcripts; quote a semester figure when planning.
- Always state the maximum alongside the number to avoid scale confusion.
