CGPA to Percentage in Bangladesh

If you're a Bangladeshi student trying to convert your CGPA to a percentage, here's the honest answer most calculators won't give you: Bangladesh has no single official CGPA-to-percentage formula. The University Grants Commission (UGC) standardised a 4.0 GPA scale, but it did not mandate one conversion to percentage — so different sources use different methods that disagree by a wide margin.

The same CGPA, three different percentages

Here is how a 3.50 CGPA converts under the three methods you'll see quoted online:

That's a spread of nearly 19 percentage points for the same CGPA. The first two are mathematically identical (dividing by 4 and multiplying by 100 is the same as ×25). The third tries to account for the fact that Bangladeshi grading is stricter than a flat proportion implies. None of them is “the official” one, because there isn't an official one.

Why a flat ×25 overstates your result

On the UGC scale, a top grade (A+) often starts at 80% of marks, not 100%. So a 4.0 CGPA does not mean you scored 100% — it means you were in the top band. A flat “CGPA × 25” treats 4.0 as 100%, which inflates the figure. That's why the offset approximation exists, and why employers and universities are cautious about any single multiplier.

Public vs private universities grade differently

The picture is muddier still because grade boundaries vary by institution. Public universities (Dhaka University, BUET) typically award A+ from around 80% of marks; many private universities (NSU, BRAC, IUB) set A from around 90%, with stricter boundaries. BUET even uses A = 4.00 rather than the UGC A = 3.75. So two students with the same CGPA from different universities did not necessarily score the same marks.

What you should actually do

• Quote your CGPA, not a converted percentage, wherever you can. Most Bangladeshi employers and universities work in CGPA and prefer it. Forcing a percentage adds error.
• If a form demands a percentage, check your official transcript first — some transcripts print a conversion or a class. Use that figure, since it's the one your university will certify.
• If your transcript gives nothing, state the method you used (e.g. “(CGPA ÷ 4) × 100”) alongside the number, so the reader knows how you got it.
• For study abroad, don't self-convert — a credential evaluator (WES) or the admissions office will read your transcript directly. See the Bangladesh to US GPA guide.

Calculate your CGPA first

Whatever you do with the percentage, get the CGPA itself right. Use the CGPA calculator with the UGC 4.0 scale (set the scale selector to a 4.0 scale and enter your courses and credit hours).

We deliberately do not publish a single “Bangladesh CGPA to percentage” number, because doing so would imply a precision that doesn't exist. Anyone claiming one official formula is guessing. Your transcript and the institution requesting the figure are the authorities.
