Credit-weighted method: SGPA = (Σ (creditᵢ × gradePointᵢ)) / (Σ creditᵢ). Ensure your grade points match your university’s scale.
Semester performance is often summarized using SGPA, typically calculated as a credit-weighted average of grade points.
The SGPA Calculator helps you compute SGPA when you know each subject’s credit and grade point. It’s ideal for students tracking progress during a semester, or quickly estimating a result before final grade submission.
SGPA calculation rules vary slightly between institutions, especially in how they map letter grades to grade points and whether they include failed subjects.
This calculator uses the standard credit-weighted approach: multiply each subject’s credit by its grade point, sum across subjects, and divide by the total credits.
To stay consistent and easy to audit, the tool shows the formula, total credits, total weighted points, and the final SGPA. That makes it simple to cross-check your computed value against your university’s method.
You’ll also find worked examples to demonstrate how one high-credit subject can influence the final SGPA more than a low-credit elective.

Answers to help you use the calculator correctly.
Use the same grade point mapping your university uses (often out of 10 or out of 4). If you have letter grades, convert them using the provided mapping.
Credits should be positive. If a subject has 0 credits (rare), it won’t affect the weighted sum but typically should be excluded.
Rules vary. Some institutions include them with their grade points; others may have special handling. Use your university’s policy.
Some institutions provide SGPA-to-percentage conversions. If your university uses a proportional method, you can convert using percentage calculator logic.
Check grading scale, rounding, and inclusion/exclusion of subjects per your university’s rules.
