What the result means

CGPA is the average of your grade points across all subjects. A higher CGPA indicates better academic performance. The percentage conversion is approximate and varies by institution.

How to use this calculator

  1. 1Enter the number of subjects.
  2. 2Select your grading scale (10-point or 4-point).
  3. 3Enter the grade point for each subject.
  4. 4Press Calculate to see your CGPA.

The formula

The calculation uses a standard, verifiable formula. Here it is in its simplest form.

CGPA = Sum of Grade Points / Number of Subjects Percentage (10-point) ≈ CGPA × 9.5 Percentage (4-point) ≈ CGPA × 25

Step-by-step example

Example: 5 subjects with grade points 9, 8, 10, 7, 9

Subjects:5Grade points:9, 8, 10, 7, 9
  1. 1Sum = 9 + 8 + 10 + 7 + 9 = 43
  2. 2CGPA = 43 / 5 = 8.6
  3. 3Percentage ≈ 8.6 × 9.5 = 81.7%

Result

CGPA = 8.6, Percentage ≈ 81.7%

What changes the result

  • Each subject's grade point contributes equally (unweighted).
  • Some institutions use credit-weighted CGPAs.
  • The conversion factor varies by institution.

Edge cases to be aware of

Unusual situations handled correctly

  • Zero grade points result in a CGPA of 0.
  • Maximum CGPA equals the scale maximum (10 or 4).
  • Different institutions may use different conversion formulas.

Common mistakes

Avoid these errors

  • Using credit-weighted averages when credits are not provided.
  • Assuming the ×9.5 conversion is universal.
  • Entering percentages instead of grade points.

Assumptions

  • All subjects have equal weight.
  • Grade points are on the selected scale.

Limitations

  • The percentage conversion is approximate.
  • Credit-weighted CGPAs require additional information.
  • Different universities may calculate CGPA differently.
