Understanding the Math Behind Your Results

1. Semester GPA Formula

Semester GPA is a credit-weighted average calculated using the standard academic formula:

GPA = Σ (Grade Points × Credit Hours) / Σ (Total Credit Hours)

For instance, if you earn an A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course, your total quality points equal (4.0 × 3) + (3.0 × 4) = 24. Dividing 24 by 7 total credits gives a GPA of 3.43. Test your course list now on the GPA & CGPA Calculator.

2. Cumulative CGPA Formula

Cumulative CGPA accounts for your prior academic standing combined with current term results:

CGPA = (Prior Quality Points + Current Quality Points) / (Prior Total Credits + Current Total Credits)

Entering your previous cumulative totals alongside your current courses into the RiazHub CGPA Calculator tool calculates your lifetime standing in real time.
