Key facts

  • CGPA = Σ(SGPA × credits) ÷ Σ(credits).
  • Semesters with more credits pull the CGPA harder — a simple average can be off.
  • Use the credits printed on your grade card, not the number of subjects.
  • If every semester has the same credits, the weighted and simple averages match.
  • Some universities compute CGPA from course grade points directly; the result is the same when SGPAs are exact.

Worked example

Sem 1: 8.0 × 20 credits · Sem 2: 9.0 × 25 credits

(160 + 225) ÷ 45 = 8.56

A simple average would say 8.50 — the heavier semester lifts it.

FAQs

Where do I find credits?

On your semester grade card or your university's scheme of study for your branch and year.

Can I leave credits blank?

Yes. Blank credits are treated as equal weight for every semester — a simple average.

Should I round SGPAs first?

No. Enter them exactly as printed; round only the final CGPA.
