SGPA to CGPA Calculator

CGPA from semester SGPAs, weighted by credits. Averaging the SGPAs equally is only correct when every semester carries the same credit load, which is rarely true.

Also called: sgpa to cgpa, semester gpa average.

Leave blank to average equally.

CGPA
8.45

8.45 across 4 semesters. No credits entered, so the semesters are averaged equally. Enter credits if the loads differed, since CGPA is credit weighted. Enter a target and the semesters remaining to see what they need to average.

How this is calculated
Method and background

How this is calculated

CGPA is the credit-weighted average of semester results, not the simple average. A semester with twenty-eight credits counts more than one with eighteen, so averaging the SGPAs directly overstates a strong light semester and understates a strong heavy one. Where a target is entered the page solves for the SGPA needed across the remaining semesters, and says when the target has become unreachable rather than returning a figure above the scale.

semesters with more credits count more, so averaging the SGPAs equally is wrong wherever credit loads differ

Method and limits

What it assumes

  • Equal credits across semesters where none are entered.

What it deliberately does not model

  • Some institutions exclude failed or repeated subjects from the CGPA, which changes the answer.
  • Credit weighting conventions differ, and a few institutions genuinely do average equally.

Frequently asked questions

Can I just average my SGPAs?
Only if every semester carried the same credits. Where the loads differ the credit-weighted average is the correct figure and the simple average is not what the transcript will show.
