Bangladeshi universities grade on a 4.0-point CGPA scale with letter grades from A+ down to F, broadly following guidance from the University Grants Commission (UGC) that most public universities, the National University, and many private universities have adopted in similar form. D (grade point 2.00) is generally the lowest passing letter grade, and F is a fail.
The Bangladeshi letter grade and CGPA scale
| Marks (%) | Letter Grade | Grade Point | Status |
|---|---|---|---|
| 80% and above | A+ | 4.00 | Pass |
| 75-79% | A | 3.75 | Pass |
| 70-74% | A- | 3.50 | Pass |
| 65-69% | B+ | 3.25 | Pass |
| 60-64% | B | 3.00 | Pass |
| 55-59% | B- | 2.75 | Pass |
| 50-54% | C+ | 2.50 | Pass |
| 45-49% | C | 2.25 | Pass |
| 40-44% | D | 2.00 | Pass (minimum) |
| Below 40% | F | 0.00 | Fail |
These percentage cutoffs follow the common UGC-aligned grading structure used by most public universities and the National University of Bangladesh, but individual universities — especially private universities — sometimes set slightly different boundaries. Always confirm against your specific institution's grading policy.
How CGPA is calculated
Bangladeshi universities calculate a semester-by-semester GPA and a cumulative CGPA across the full program, weighted by each course's credit hours — structurally the same approach used in the US:
CGPA = Σ(Grade Point × Credit Hours) ÷ Σ(Credit Hours)
This is why Bangladesh's CGPA is often described as one of the more directly comparable systems to US GPA among South Asian grading systems: both use a 4.0 ceiling and a credit-weighted average, even though the underlying percentage cutoffs for each letter grade differ somewhat from typical US grading scales.
Passing thresholds and honors classifications
D (grade point 2.00, roughly 40% marks) is the minimum passing grade for an individual course under the common UGC-aligned scale. Overall degree classifications and honors (such as graduating with a "First Class" designation in older nomenclature, or specific CGPA-based Dean's List recognition at individual universities) are set by each institution's academic regulations rather than a single uniform national standard.
If you're tracking a cumulative average across multiple semesters, the CGPA Calculator can handle the credit-weighted math directly; for a single semester's grade point average, the GPA Calculator works the same way.
Converting Bangladeshi CGPA to a US 4.0 GPA
Because both systems use a 4.0 scale, conversion is more direct than with many other national systems, though the percentage bands underlying each grade point still differ somewhat from typical US grading norms. A commonly referenced approximate mapping looks like this:
| Bangladeshi Grade | Bangladeshi Grade Point | Approx. US Letter | Approx. US GPA Points |
|---|---|---|---|
| A+ | 4.00 | A | 4.0 |
| A / A- | 3.50 - 3.75 | A- / B+ | 3.3 - 3.7 |
| B+ / B | 3.00 - 3.25 | B | 3.0 |
| B- / C+ | 2.50 - 2.75 | C+ | 2.3 - 2.7 |
| C / D | 2.00 - 2.25 | C / D | 1.0 - 2.0 |
| F | 0.00 | F | 0.0 |
Worked example: A student's Bangladeshi transcript shows the following results:
| Course | Credit Hours | Bangladeshi Grade | Bangladeshi Grade Point |
|---|---|---|---|
| Data Structures | 3 | A+ | 4.00 |
| Digital Logic Design | 3 | A- | 3.50 |
| Technical Writing | 2 | B+ | 3.25 |
| Discrete Mathematics | 3 | B | 3.00 |
CGPA = ((4.00×3) + (3.50×3) + (3.25×2) + (3.00×3)) ÷ 11 = (12.0 + 10.5 + 6.5 + 9.0) ÷ 11 = 38.0 ÷ 11 ≈ 3.45
This CGPA of 3.45 on Bangladesh's 4.0 scale would generally be read as roughly comparable to a similar 3.3-3.5 range on a US 4.0 GPA scale, though the exact US-equivalent letter grades for each individual course may shift slightly depending on which conversion table a receiving institution uses.
Common edge cases
- Cutoffs vary by institution: The percentage-to-grade-point boundaries shown above reflect the common UGC-aligned structure, but private universities in particular sometimes use different cutoffs (for example, a slightly higher or lower threshold for A+) — always check the specific institution's grading policy document.
- Older vs. newer grading conventions: Some older Bangladeshi academic records (particularly pre-university, or from institutions that later switched systems) use a simple first/second/third division or straight percentage system rather than CGPA — don't assume every Bangladeshi academic document uses the 4.0 letter-grade scale.
- Retake and grade improvement policies: How a repeated or improved course grade affects the cumulative CGPA varies by university policy (some average both attempts, others replace the earlier grade) — check your specific institution's rules if you're recalculating a CGPA that includes any retaken courses.
- No single authoritative Bangladesh-to-US conversion table: Treat any conversion table, including the one above, as an approximation, and confirm with your receiving institution's admissions or credential evaluation office when precision matters.
