How IUB CGPA Calculation Works (Formulas)
Semester GPA Formula
For a single semester, the formula represents the weighted average of your performance.
Step 1: Calculate "Quality Points" for each course: (Credits × Grade Point).
Step 2: Sum all Quality Points.
Step 3: Divide by Total Credits Attempted.
IUB BD CGPA Calculator – Worked Example
Consider a student taking 3 courses in Autumn semester:
- ENG101 (3 Credits): Grade A (4.0) → 3 × 4.0 = 12.0 Points
- MAT101 (3 Credits): Grade B+ (3.3) → 3 × 3.3 = 9.9 Points
- CSC101 (4 Credits): Grade A- (3.7) → 4 × 3.7 = 14.8 Points
Total Credits: 3 + 3 + 4 = 10
Total Quality Points: 12.0 + 9.9 + 14.8 = 36.7
Semester GPA: 36.7 ÷ 10 = 3.67
What Is a Good CGPA in IUB?

Common CGPA Mistakes IUB Students Make
- Ignoring Retakes: If you retake a course to improve a grade (e.g., C to B+), the new grade replaces the old one in CGPA calculation, but the old grade remains on the transcript. This tool helps you simulate that impact.
- Confusing GPA with CGPA: GPA is for one semester; CGPA includes all semesters. Use the "Cumulative" tab in this tool for overall results.
- Rounding Errors: IUB system calculates to multiple decimal places. Manual math often fails due to early rounding.
