CGPA Calculator

Calculate your CGPA from semester SGPAs, with or without credits.

Add the SGPA of each semester. If you also enter the credits, the calculator gives you the exact credit-weighted CGPA. Without credits it takes a simple average, which is close when every semester has similar credits.

How CGPA is calculated

CGPA = Σ (SGPA × credits of that semester) ÷ Σ credits

Example: semester 1 has SGPA 8.0 with 20 credits, and semester 2 has SGPA 9.0 with 24 credits.

CGPA = (8.0 × 20 + 9.0 × 24) ÷ (20 + 24) = (160 + 216) ÷ 44 = 8.55.

A simple average would give 8.5. The difference comes from the second semester having more credits.

How SGPA is calculated

SGPA works the same way inside one semester: multiply each subject's grade point by its credits, add them up, and divide by the total credits of that semester.

SGPA = Σ (grade point × subject credits) ÷ Σ subject credits

Grade points usually follow the UGC 10-point scale: O = 10, A+ = 9, A = 8, B+ = 7, B = 6, C = 5, P = 4 and F = 0. Some universities use slightly different points, so check your marksheet. See the grading system in India.

Next step: CGPA to percentage

Once you have your CGPA, convert it with the CGPA to percentage calculator using your university's formula.

Frequently asked questions

Do I need credits to calculate CGPA?

For an exact CGPA, yes. Without credits you get a simple average, which is close if all semesters have similar credits.

Is CGPA the average of all SGPAs?

Only if every semester has the same credits. Otherwise CGPA is the credit-weighted average.

Can CGPA be more than 10?

No. On a 10-point scale the highest CGPA is 10.
