A proper review must distinguish between two types of calculations students look for:
Input: list of courses where each course has credits, gradeLetter
Map gradeLetter -> gradePoint (use AIUB table)
qualityPoints = 0
totalCredits = 0
for each course in list:
if course.gradeLetter in countedGrades:
gp = gradePoint(course.gradeLetter)
qualityPoints += gp * course.credits
totalCredits += course.credits
if totalCredits == 0:
CGPA = 0
else:
CGPA = qualityPoints / totalCredits
Output CGPA rounded per official rule
For cumulative updates, store cumulativeQualityPoints and cumulativeCredits and add term values before dividing.
Many students think a 'D' is a pass. It is, but it is a GPA killer (1.00 point). If you get a D in a 3-credit course, you need two A+'s (rare) to compensate. Always retake a D if your CGPA is below 3.00.
A CGPA calculator tailored to AIUB is not just a convenience — it is a strategic academic tool. It enables students to:
Students are advised to use official transcripts as the source of truth, but a well-designed CGPA calculator (manual or digital) is highly recommended for ongoing academic planning.

To calculate your CGPA at American International University-Bangladesh (AIUB), you must use a weighted average system based on credit hours and grade points. The university operates on a 4.00 scale, where your overall performance is determined by dividing your total earned quality points by your total attempted credits. AIUB Official Grading Scale
AIUB uses a specific point system to convert your numerical scores into grade points: Numerical % Letter Grade Grade Point 90 – 100 A+ 85 – < 90 A 80 – < 85 B+ 75 – < 80 B 70 – < 75 C+ 65 – < 70 C 60 – < 65 D+ 50 – < 60 D F How to Calculate CGPA Manually
You can follow these four steps to find your current standing:
Find Quality Points for each course: Multiply the Grade Point you earned by the course's Credit Hours (e.g., an 'A' in a 3-credit course gives
Sum Total Quality Points: Add up all these points across all semesters. cgpa calculator aiub
Sum Total Credit Hours: Add up all credit hours you have attempted. Divide:
Example Calculation:If you took two semesters with 15 credits each and earned 57 points in the first and 50.25 in the second, your CGPA would be:
57+50.2515+15=107.2530=3.575≈3.58the fraction with numerator 57 plus 50.25 and denominator 15 plus 15 end-fraction equals 107.25 over 30 end-fraction equals 3.575 is approximately equal to 3.58
Note: AIUB rounds to two decimal places. If the third digit is 5 or higher, the second digit increases by one. Essential AIUB Academic Policies
Graduation Requirement: You must maintain a minimum CGPA of 2.50 to graduate.
Academic Probation: If your CGPA falls below 2.50, you are placed on probation for one semester. Failing to recover within the next semester can lead to termination of enrollment. Retake Rules:
You can retake a course if you receive a grade below 2.50 (passing 'D' or below).
For the first four (UG) or two (PG) courses, a retaken grade replaces the 'F' in the CGPA calculation. From the fifth (UG) or third (PG) 'F' onward, both the 'F' and the new grade are counted, which can significantly lower your CGPA.
Scholarship Eligibility: To maintain a merit-based scholarship, students typically need a CGPA of 3.75 or higher with no failing grades or retakes. If you'd like, I can:

To calculate your Cumulative Grade Point Average (CGPA) at American International University-Bangladesh (AIUB), you must follow the university's specific grading scale and weightage system. AIUB uses a 4.00 scale, where the calculation is based on the total points earned divided by the total credits attempted. 📊 AIUB Grading Scale
The following table shows how numerical marks translate into grade points at AIUB: Numerical Range Letter Grade Grade Point 90% – 100% A+ 85% – < 90% A 80% – < 85% B+ 75% – < 80% B 70% – < 75% C+ 65% – < 70% C 60% – < 65% D+ 50% – < 60% D F Calculation Formula
AIUB calculates CGPA by taking the sum of the products of grade points and credit hours for all courses, then dividing by the total number of credit hours. Formula:
CGPA=∑(Grade Point×Credit Hours)∑Credit HoursCGPA equals the fraction with numerator sum of open paren Grade Point cross Credit Hours close paren and denominator sum of Credit Hours end-fraction Calculation Example: If you take 3 courses in a semester: Course 1: 3 Credits, Grade A+ (4.00) →3×4.00=12.00right arrow 3 cross 4.00 equals 12.00 Course 2: 3 Credits, Grade B+ (3.50) →3×3.50=10.50right arrow 3 cross 3.50 equals 10.50 Course 3: 3 Credits, Grade A (3.75) →3×3.75=11.25right arrow 3 cross 3.75 equals 11.25 Total Points: Total Credits: GPA: 📝 Key Academic Policies
Graduation Requirement: Students must maintain a minimum CGPA of 2.50 to earn their degree.
Academic Probation: If your CGPA falls below 2.50, you are placed on probation for one semester. Failure to improve within the deadline can lead to termination. Retake Rules:
You can retake a course if the grade is below 2.50 (e.g., D+, D, or F). SGPA (Semester GPA): Most tools handle this perfectly
For the first 4 F grades (Undergraduate) or 2 F grades (Graduate), the new grade will be used for CGPA, though the 'F' still appears on the transcript. Beyond this limit, both the 'F' and the new grade are factored into the CGPA. Academic Honors: Summa Cum Laude (Gold): CGPA 3.95 – 4.00. Magna Cum Laude (Silver): CGPA 3.80 – 3.94. Cum Laude (Bronze): CGPA 3.65 – 3.79.
💡 Pro-tip: For a quick calculation, you can use independent tools like the AIUB Student Support or official portal resources if available. Grading System - AIUB
To understand the calculator, you need to understand the formula. Many students confuse SGPA (Semester GPA) with CGPA (Cumulative GPA).
The Formula: $$CGPA = \frac\textTotal Quality Points Earned\textTotal Credit Hours Attempted$$
Where:
American International University-Bangladesh (AIUB) follows a semester-based credit hour system with a 4.00 grading scale. A CGPA (Cumulative Grade Point Average) calculator is an essential tool for students to track their academic performance, project future GPAs, and identify grade requirements for target CGPAs.
This report outlines the grading system, the calculation methodology, features of an ideal AIUB-specific CGPA calculator, and a practical example.
Your CGPA is more than just a number; it determines your eligibility for scholarships, internships, and graduation honors. While manual calculation is a good skill to have, leveraging an AIUB CGPA Calculator saves time and ensures accuracy.
