How is SGPA calculated?

Multiply each subject's credits by its grade points, add the results, then divide by the total credits.

What grade-point scale should I use?

Use your institution's own grading system. Scales differ, so this calculator doesn't assume a maximum.

Can a subject have 0 grade points?

Yes. A 0 still adds its credits to the total, which lowers your SGPA.

Why can't credits be 0?

A subject with 0 credits has no weight, and if all credits are 0 the SGPA can't be calculated.

How many subjects can I add?

Up to 20 subjects, with at least one.

Grading scales and grade-point values differ between institutions. Enter grade points exactly as your institution's grading system defines them; this calculator does not assume a maximum scale.

SGPA = sum of (credits × grade points) ÷ total credits. For example, 4 credits at 8 points and 3 credits at 9 points give (32 + 27) ÷ 7 = 8.43. Enter grade points on your own institution's grading scale.

Subjects with more credits affect your SGPA more than subjects with fewer credits.

What is the SGPA Calculator?

What the tool does, who it is for and what it cannot tell you.

SGPA (semester grade point average) is a credit-weighted average of your grade points for one semester. Subjects with more credits count more.

Each institution sets its own grading system — which grades map to which points and what the maximum is. Enter the grade points your institution awards.

SGPA Calculator formula

The exact maths behind every number on this page.

SGPA = Σ(credits × grade points) ÷ Σ credits

credits: Credit value of each subject
grade points: Points earned in that subject on your institution's scale

SGPA Calculator calculation example

Hypothetical example: three subjects — 4 credits at 8 points, 3 credits at 9 points, 2 credits at 7 points.

1Weighted points4×8 + 3×9 + 2×7 = 32 + 27 + 14 = 73
2Total credits4 + 3 + 2 = 9
3SGPA73 ÷ 9 ≈ 8.11

The SGPA is about 8.11.

Important assumptions

What this calculation includes, and what it leaves out.

Every subject entered counts toward the SGPA.
No institution-specific rules (such as excluding failed or audit subjects) are applied.

Financial tips

Practical guidance to act on your result.

Use the credits printed on your grade card or syllabus, not the number of classes.
To estimate CGPA from SGPA values, check your institution's rule — many weight each semester by its credits.
