Calculate your SGPA from subject credits and grade points, then convert it to a percentage or combine semesters into CGPA.
Enter credit hours and grade points for current semester
Save this semester and add Semesters 1 through 8 to calculate your overall cumulative CGPA.
First Class with Distinction
SGPA (Semester Grade Point Average) is a credit-weighted average: SGPA = (sum of Credits x Grade Point for each subject) / (sum of Credits). Each subject contributes to the total in proportion to its credit hours, not equally.
Because SGPA is credit-weighted, a 4-credit subject with a high grade point affects the result more than a 1-credit lab with the same grade point, so it is not the same as a simple average of grade points. Cumulative CGPA extends this same credit-weighted approach across every saved semester rather than just one.
With subjects worth 4, 4, 3, 3, and 1.5 credits earning grade points of 10, 9, 8, 9, and 10, total credits are 15.5 and total grade points are 142, giving an SGPA of 142 / 15.5 = 9.16. Converting that SGPA to a percentage using the CBSE 9.5 multiplier gives 9.16 x 9.5 = 87.0%, while the VTU/AICTE formula would give (9.16 - 0.75) x 10 = 84.1%.
Use the Percentage to CGPA Calculator when you already have percentage marks and need the equivalent grade point instead of building it from subject credits, and the CGPA to Percentage Calculator once all semesters are combined into a final CGPA.

SGPA measures one semester; CGPA measures your entire academic record. Here is the exact credit-weighted formula for both, with a multi-semester example.
