CGPA to Percentage Conversion — Complete Guide for BD Students
Why there is no single official CGPA-to-percentage formula in Bangladesh, the formulas commonly used, and what to put on your CV or job application.
One of the most common questions on Bangladeshi student forums is: "What is my CGPA in percentage?" The honest answer is that there is no single official conversion formula, and using the wrong one on a job application or study-abroad form can make you look either dishonest or unprepared.
This guide explains how the conversion actually works in Bangladesh, the most commonly accepted formulas, and when you should — and shouldn't — convert.
Why there is no single official formula
Bangladesh's University Grants Commission (UGC) defines the 4.00 GPA scale, but it does not publish a percentage-conversion formula. Each university and each ministry uses its own:
- Most public universities issue transcripts that already include a "percentage of marks" column alongside the CGPA — that is the authoritative number for that university.
- Private universities sometimes only issue CGPA. They will provide a percentage on request.
- The Ministry of Public Administration uses one formula for BCS eligibility; WES (used for North American university applications) uses another.
If you are filling a job, scholarship, or visa form, use the percentage printed on your transcript wherever possible. Only fall back to a formula when no transcript value exists.
The three commonly used formulas
1. The 10 × CGPA formula (used by some Indian universities, not standard in Bangladesh)
Percentage = CGPA × 10
So a 3.5 CGPA = 35%. This is obviously wrong for the Bangladeshi 4.00 scale and should never be used. It only makes sense in systems with a 10.00 CGPA scale.
2. The 25 × CGPA formula (a rough approximation)
Percentage = CGPA × 25
This puts a 4.00 CGPA at 100% and a 3.00 at 75%. It's the formula most commonly used by students online, but it inflates the percentage for high CGPAs and is rarely accepted by official bodies.
3. The grade-cutoff method (most accurate)
Map each course's grade back to the midpoint of its marks range, then average. Because the UGC scale defines:
- A+ (4.00) = 80–100 (midpoint 90)
- A (3.75) = 75–79 (midpoint 77)
- A− (3.50) = 70–74 (midpoint 72)
- B+ (3.25) = 65–69 (midpoint 67)
- B (3.00) = 60–64 (midpoint 62)
- B− (2.75) = 55–59 (midpoint 57)
- C+ (2.50) = 50–54 (midpoint 52)
- C (2.25) = 45–49 (midpoint 47)
- D (2.00) = 40–44 (midpoint 42)
You weight the midpoint by credits, the same way you compute CGPA. This produces a percentage that closely matches what most Bangladeshi universities print on transcripts.
Quick reference table
| CGPA | Letter | Approx. Percentage | UK Classification |
|---|---|---|---|
| 4.00 | A+ | 85–100% | First Class |
| 3.75 | A | 75–79% | First Class |
| 3.50 | A− | 70–74% | First Class |
| 3.25 | B+ | 65–69% | Upper Second (2:1) |
| 3.00 | B | 60–64% | Upper Second (2:1) |
| 2.75 | B− | 55–59% | Lower Second (2:2) |
| 2.50 | C+ | 50–54% | Lower Second (2:2) |
| 2.25 | C | 45–49% | Third Class |
| 2.00 | D | 40–44% | Pass |
For specific use cases
BCS and government jobs
The Bangladesh Public Service Commission (BPSC) explicitly converts CGPA using a fixed chart in its circular. The cutoffs for eligibility (e.g. "first division equivalent") are defined there. Always download the latest circular instead of using a generic formula.
Study abroad — US universities
WES (World Education Services) re-evaluates your transcript using its own internal methodology. You don't convert; WES does it for you, and the WES report is what universities trust.
Study abroad — UK universities
UK universities map your CGPA directly to their classification system (First, 2:1, 2:2). Use the table above as a rough guide, but check each university's "international qualifications" page for Bangladesh.
Study abroad — Australia and Canada
Most institutions accept your transcript's percentage column. If your transcript only shows CGPA, contact admissions and ask which conversion they use.
What to write on a CV or job application
- Write "CGPA: 3.65 / 4.00" — always include the scale.
- Don't convert to percentage unless the form specifically asks for one.
- If a Bangladeshi employer asks for "marks," quote the percentage from your transcript, not a self-computed one.

FAQ
Is CGPA × 25 the official conversion?
No. It's a commonly used approximation but is not endorsed by UGC. Use your transcript's percentage column whenever possible.
How do US universities convert my CGPA?
They typically don't — they use WES or a similar credential evaluator, which uses its own internal methodology.
What CGPA is equivalent to a First Class?
Approximately 3.50 and above on the 4.00 scale, though some employers set the cutoff at 3.00.
