What this cgpa calculator does

CGPA Calculator combines semester GPAs using the credits earned in each semester. A 22-credit semester counts more than a 16-credit one, which is how most universities compute a cumulative average. Enter one row per semester and the credit-weighted CGPA updates immediately.

The percentage converter uses a simple linear mapping you choose, not an official formula. Universities publish their own conversion tables, and many employers ask for the percentage or a specific band. If your institution has a conversion rule, use that instead of the estimate here.

Why use it

  • Get a cumulative average without recalculating a long spreadsheet.
  • See how a strong semester with few credits affects the total.
  • Test what a target GPA would do to your CGPA before exams.

How to use it

  1. 1Enter the GPA and credits for each completed semester.
  2. 2Add rows for any further semesters.
  3. 3Read the weighted CGPA and total credits.
  4. 4Use the converter only as a rough percentage estimate.

Worked examples

Two semesters

Input

20 credits at 8.2, 22 credits at 8.6

Output

A CGPA closer to 8.6 because the second semester carries more credits.

Uneven credits

Input

30 credits at 7.0, 10 credits at 9.0

Output

The result is 7.5, not the simple mean of 8.0.

Common mistakes

  • Averaging semester GPAs without weighting by credits.
  • Mixing 4-point and 10-point scales in one table.
  • Treating the percentage conversion as an official university formula.

Frequently asked questions

What is the difference between GPA and CGPA?
GPA usually covers one term or year. CGPA is the cumulative average across all completed terms.
How is the CGPA weighted?
Each semester GPA is multiplied by its credits; the total is divided by all credits attempted.
Does it handle a 4-point scale?
Yes. Use GPAs on whatever scale your institution uses; the weighting is identical. Do not mix scales in one calculation.
Is my data uploaded?
No. The calculation runs in this tab.
