What is the difference between GPA and CGPA?

GPA (Grade Point Average) refers to your academic performance in a single semester, while CGPA (Cumulative Grade Point Average) is the weighted average across all semesters up to the current point in your degree. Many universities calculate a semester GPA first, then update the cumulative CGPA.

How is GPA calculated from grades and credits?

GPA = (Sum of [Grade Points × Credit Hours] for all subjects) ÷ Total Credit Hours. For example, if you scored A (4.0) in a 3-credit course and B+ (3.3) in a 4-credit course: (4.0×3 + 3.3×4) ÷ (3+4) = (12 + 13.2) ÷ 7 = 3.6 GPA.

What is a 4.0 GPA in the Indian 10-point system?

A 4.0 GPA on the US scale corresponds roughly to an outstanding CGPA of 9.5–10 on the Indian 10-point scale, indicating top-tier academic performance. The exact conversion varies by institution.

Can I calculate my SGPA (Semester GPA) with this tool?

Yes. Entering only the subjects from a single semester gives you the SGPA for that semester. To calculate cumulative CGPA, you would typically need a weighted average across all semesters, which your university registrar office computes officially.

What happens if I leave a subject grade blank?

Subjects with no grade selected or zero credit hours are excluded from the GPA calculation. Only subjects with a valid grade and at least 1 credit hour are included in the weighted average.

What Is GPA?

GPA, or Grade Point Average, is a standardised measure of academic performance. Each grade (A, B, C, etc.) is assigned a numerical grade point value. The GPA is calculated as the weighted average of those grade points, where each subject is weighted by its credit hours.

GPA Formula:
GPA = (Sum of Grade Points × Credits for each subject) ÷ Total Credit Hours

A subject worth 4 credits contributes four times more to the GPA than a 1-credit elective, which accurately reflects the relative academic load of each course.

Supported Grading Scales

US 4.0 Scale (International): The most widely used scale globally. Grades range from A+ (4.0) through to F (0.0), with + and − modifiers adjusting the grade point by 0.3–0.7. This scale is used across US universities and adopted by many international institutions.

Indian 10.0 Scale: Used by most Indian universities following UGC guidelines. Grades are O (10), A+ (9), A (8), B+ (7), B (6), C (5), P (4), F (0). This scale is common across IITs, NITs, and affiliated universities.

Academic Standing Classification

4.0 Scale:

3.7–4.0: Summa Cum Laude
3.3–3.69: Magna Cum Laude
3.0–3.29: Cum Laude
2.0–2.99: Satisfactory
1.0–1.99: Poor Standing
Below 1.0: Academic Probation

10.0 Scale:

9.0–10.0: Outstanding
8.0–8.99: Excellent
7.0–7.99: Very Good
6.0–6.99: Good
5.0–5.99: Average
4.0–4.99: Pass
Below 4.0: Fail
