What is CGPA and why does it matter?
CGPA stands for Cumulative Grade Point Average. It represents your overall academic performance across all completed semesters. In Bangladesh’s higher education system, your CGPA is calculated by dividing your total grade points by the total credit hours attempted. Universities use it to determine academic honours, scholarship eligibility and whether you meet graduation requirements. For example, at IUB you need at least a 2.0 CGPA to graduate, and a CGPA below 2.0 may place you on probation. It’s worth paying attention!
A common question is “How is CGPA different from GPA?” A GPA measures your performance in a single semester, while CGPA averages your performance across multiple semesters. If you’re still early in your studies, one bad term can drag your CGPA down—so it pays to track it regularly.
Official grading scales
To calculate CGPA accurately, you need to convert letter grades to grade points. Each university has its own scale.
NSU grading scale (4.0 system)
The official North South University grading policy assigns grade points to score ranges such as A (93+ = 4.0 points), A‑ (90–92 = 3.7), B+ (87–89 = 3.3) down to D (60–66 = 1.0) and F (below 60 = 0.0). Knowing these ranges helps you understand how each percentage affects your CGPA.
| NSU score range | Letter grade | Grade point |
|---|---|---|
| 93 and above | A (Excellent) | 4.0 |
| 90–92 | A‑ | 3.7 |
| 87–89 | B+ | 3.3 |
| 83–86 | B (Good) | 3.0 |
| 80–82 | B‑ | 2.7 |
| 77–79 | C+ | 2.3 |
| 73–76 | C (Average) | 2.0 |
| 70–72 | C‑ | 1.7 |
| 67–69 | D+ | 1.3 |
| 60–66 | D | 1.0 |
| Below 60 | F | 0.0 |
BRAC University grading scale (BRACU)
BRACU uses a similar 4.0 system but with slightly different ranges. According to GPAWise, an A+ covers 80–100 with 4.00 points, A is 75–79 (3.75 points), A‑ is 70–74 (3.50 points), and the scale continues down to F (below 40 = 0.00). Unlike many universities, BRACU rounds up the CGPA if the third decimal is 5 or more—for example, a calculated CGPA of 3.895 becomes 3.90
| BRACU marks range | Letter grade | GPA value |
|---|---|---|
| 80–100 | A+ | 4.00 |
| 75–79 | A | 3.75 |
| 70–74 | A‑ | 3.50 |
| 65–69 | B+ | 3.25 |
| 60–64 | B | 3.00 |
| 55–59 | B‑ | 2.75 |
| 50–54 | C+ | 2.50 |
| 45–49 | C | 2.25 |
| 40–44 | D | 2.00 |
| Below 40 | F | 0.00 |
IUB grading scale (IUB)
IUB follows a straightforward 4.0 scale: A for 90–100 (4.0 points), A‑ for 85–89 (3.7 points), B+ for 80–84 (3.3 points), B for 75–79 (3.0 points) and so on down to F (below 45 = 0.0).
| IUB score range | Letter grade | Grade point |
|---|---|---|
| 90–100 | A | 4.0 |
| 85–89 | A‑ | 3.7 |
| 80–84 | B+ | 3.3 |
| 75–79 | B | 3.0 |
| 70–74 | B‑ | 2.7 |
| 65–69 | C+ | 2.3 |
| 60–64 | C | 2.0 |
| 55–59 | C‑ | 1.7 |
| 50–54 | D+ | 1.3 |
| 45–49 | D | 1.0 |
| Below 45 | F | 0.0 |
How to calculate CGPA manually
Understanding the formula is empowering (even when you use a calculator). Here’s a universal approach:
Convert each course grade to a grade point – Use the appropriate grading table above.
Multiply each grade point by the course’s credit hours – this produces the Total Grade Points (TGP) for each course.
Sum all Total Grade Points.
Sum all credit hours.
Divide the total grade points by the total credit hours – the result is your CGPA
Example: Suppose an IUB student completed five courses with the following grades and credits: ENG 101 (3 credits, A), MAT 102 (2 credits, B+), CSC 103 (3 credits, B), PHY 104 (4 credits, A‑), and ECO 105 (3 credits, C+). Multiplying grade points by credits and summing yields 49.3 grade points. Dividing by 15 total credits gives a CGPA of 3.29.
While it’s good to know the method, doing this repeatedly can be tedious—hence the need for a reliable online calculator.
