How to use this calculator

  1. Type the SGPA of each semester in the boxes above (add more semesters with the button).
  2. Credits are optional. If you fill credits for every semester, you also get the credit-weighted CGPA, which most universities use officially.
  3. Your CGPA updates instantly as you type.

How SGPA becomes CGPA

Simple average: CGPA = (SGPA of all semesters) ÷ (number of semesters). Example: SGPAs of 8.5 and 9.0 give (8.5 + 9.0) ÷ 2 = 8.75 CGPA.

Credit-weighted: CGPA = Σ (SGPA × credits) ÷ (total credits). Semesters with more credits count more. When both are shown and your university is credit-based, use the weighted figure.

The percentage shown is an estimate using the most common formula, CGPA × 9.5. For other formulas, use our CGPA to Percentage Calculator.

Frequently asked questions

What is the difference between SGPA and CGPA?

SGPA is your grade average for one semester. CGPA is the combined average across all the semesters you have completed.

Should I use the simple average or the weighted CGPA?

If every semester has the same total credits, both are identical. If credits differ between semesters, most universities use the credit-weighted CGPA — use that one.

How many semesters can I add?

Up to 12 semesters, which covers most degree programmes.

Is my data saved anywhere?

No. The calculation happens in your browser; nothing is sent or stored.
