NU BD CGPA Calculation Formula

Official mathematical equations for SGPA, CGPA, and Percentage Conversion

Semester Level4-point

SGPA Formula

Calculates single semester grade performance weighted by subject credits:

SGPA = Σ(C_i × GP_i) / ΣC_i

Where C_i = Course Credits, GP_i = Grade Points secured.

Cumulative LevelAll Semesters

CGPA Formula

Weighted average of all completed semesters up to current session:

CGPA = Σ(SGPA_j × C_j) / ΣC_j

Where SGPA_j = Semester SGPA, C_j = Total Semester Credits.

Official EquivalenceNU BD Ordinance

Percentage Conversion

Official institutional formula to derive aggregate percentage:

Percentage (%) = (CGPA / 4.0) × 100

Standard official formula recognized for recruitment, higher admissions & competitive exams.

Important Regulatory Rule: At National University Bangladesh, grade points are awarded based on both continuous internal assessments (quizzes, mid-terms, sessionals, laboratory experiments) and semester-end examinations. Cumulative GPA (CGPA) is not a simple arithmetic average of semester SGPAs, but a credit-weighted aggregate across all earned credits.

How National University Bangladesh Calculates CGPA

Step-by-step academic evaluation procedure with a worked practical example

Obtain Letter Grades

Based on total marks in theory and practicals, the student receives letter grades corresponding to official grade points on a 4.0 scale.

Multiply Course Credits

Multiply each course's credit hours by the numeric grade points obtained to find the Quality Credit Points (Credits × Grade Point).

Compute Semester SGPA

Divide total quality credit points earned in the term by the total registered semester credits: SGPA = Total Points / Total Credits.

Calculate Final CGPA

Aggregate all semester credit points and divide by total completed degree credits to yield the cumulative CGPA and equivalent percentage.
