CGPA Calculator
Average completed term GPAs equally or by entered credits without percentage or grading-scale conversion.
Aggregate completed term GPAs
Select a mode explicitly. Changing mode clears incompatible rows rather than reinterpreting them.

CGPA result
Select a mode, enter at least one active row, and calculate. Blank structural rows are ignored.
Formulas and worked examples
Simple CGPA = sum of active term GPAs / active term count. The terms 3.2, 3.5, and 3.8 give 10.5 / 3 = 3.5 CGPA.
Weighted CGPA = sum of each GPA x credits / total credits. GPA 3.0 over 12 credits and GPA 4.0 over 18 credits give (36 + 72) / 30 = 3.6 weighted CGPA.
Row products and totals retain full numeric precision until final formatting.
Assumptions and limitations
All GPA values must use one institutional scale. Simple mode treats every term equally; weighted mode uses only the credits entered for each row.
The calculator does not convert CGPA to percentage or between GPA scales. Institutions may calculate from individual courses and apply exclusions, transfer, repeat, rounding, or truncation rules. This is not an official CGPA certification.
Use the GPA Calculator to project one new term, or the Grade Calculator for a remaining assessment.
Quick answers
What this calculator answers
- Simple mode: Averages completed term GPAs equally.
- Weighted mode: Weights each completed term GPA only by the credits entered for that row.

Accuracy and limitations
Calzivo tools are built for practical estimates, conversions, and checks. Some tools use standard formulas or simplified assumptions, and results can be affected by input accuracy, rounding, units, local rules, or changing official requirements.
Education results depend on the scale and grading rules you enter. Schools and institutions may use different official policies, so confirm important results with your syllabus or records office.

Frequently Asked Questions
Common questions about CGPA Calculator and how to read the result.
What is the difference between simple and weighted CGPA?
Simple mode gives every entered term equal influence. Weighted mode gives more influence to terms with more entered credits.
Can a term GPA be zero?
Yes. An explicit zero GPA is valid. In weighted mode its credits must still be entered and greater than zero.
Does this convert CGPA to percentage?
No. It only aggregates GPA values already expressed on the same institutional scale.
Is this an official CGPA?
No. Institutions may calculate from individual courses and apply repeat, exclusion, transfer, rounding, or truncation rules.
