The rule for CGPA to percentage in Bangladesh

The Ministry of Education's notification of 2 June 2009 counts the top of a university's CGPA scale, 4 or 5, as 80% marks. So the percentage is 80 ÷ scale × CGPA: CGPA × 20 on a 4-point scale, and CGPA × 16 on a 5-point scale. The class comes from the percentage:

The notification prints the percentages, and calls these first, second and third class or division. It gives no class below 33%. The CGPA columns are worked out from the rule.

Its own examples: 3.00 on a 4-point scale is 60%, first class, and 3.00 on a 5-point scale is 48%, second class.

Made-up example: a CGPA of 3.43 on a 4-point scale is 3.43 × 20 = 68.6%, first class. A CGPA of 2.80 is 2.80 × 20 = 56%, second class.

Pick the right scale

The same CGPA gives a lower percentage on a 5-point scale, because 80% then sits at 5.00. Made-up example: 3.43 on a 5-point scale is 3.43 × 16 = 54.88%, second class, not 68.6%.

On a 5-point scale, second class starts at a CGPA of 2.8125, between two CGPAs with 2 decimals. Made-up example: 2.81 is 44.96%, third class, and 2.82 is 45.12%, second class.

SSC and HSC GPA to division

The Ministry of Education's notification of 2 March 2010 sets the division for SSC, HSC and equivalent exams, until further order. In the calculator, pick SSC or HSC GPA, to a division.

Made-up example: an SSC GPA of 2.75 is second division. Below 1.00 the notification gives no division.

The 2010 notice amends the one of 2 June 2009 for these exams and leaves its other parts, the CGPA rule among them, as they were. The 2009 notice had used 4.00 and 3.00 as its cut-offs for results from 2004 on, and 3.50 and 2.50 for SSC 2001 to 2003 and HSC 2003. The 2010 notice names no years, so it appears to replace both, but it does not say so.

Where the rule comes from

Both notifications are in one PDF, a scan of the signed notices. The Rajshahi Education Board's page links it under the title প্রচলিত গ্রেডিং পদ্ধতির সঙ্গে পূর্বের বিভাগ/শ্রেণীর সমতাকরণ, the equivalence of the current grading system with the former divisions and classes. We read the PDF from its page images on 4 November 2026: the notice of 2 March 2010 is on page 1, and the notice of 2 June 2009 on page 2.

We found no rounding rule in either notice, so the calculator shows the exact percentage. Since 80 ÷ 4 and 80 ÷ 5 are whole numbers, a CGPA with 2 decimals never gives a percentage with more than 2.

Not verified yet

How an SSC or HSC GPA is worked out, and how the fourth subject counts: no board or ministry rule could be opened, because the board sites showed bot checks or did not load. How universities average and round a CGPA: the pages opened give the UGC scale but no formula. Whether the 2009 cut-offs for SSC 2001 to 2003 and HSC 2003 still apply: the 2010 notification names no years.

So GradeCat has no SSC or HSC GPA calculator and no university CGPA calculator for Bangladesh yet. We add a rule only after we have read it in the document that sets it.

The percentage that counts

This calculator applies the published rule to the number you type. It is an estimate, not an official result. Where a form asks for a percentage, a class or a division, the figure that counts is the one your university or board gives.

CGPA to percentage FAQ

What CGPA is first class in Bangladesh?

By the Ministry of Education's 2009 rule, 60% and above is first class. On a 4-point scale that is a CGPA of 3.00 or more, since 3.00 × 20 = 60%. On a 5-point scale it is 3.75 or more, since 3.75 × 16 = 60%.

What is 3.50 CGPA in percentage?

On a 4-point scale, 3.50 × 20 = 70%, first class. On a 5-point scale, 3.50 × 16 = 56%, second class.

Is a CGPA of 3.00 first class?

On a 4-point scale, yes: 3.00 × 20 = 60%, first class. On a 5-point scale, no: 3.00 × 16 = 48%, second class. These are the notification's own examples.

Why is a CGPA of 4.00 only 80%?

The notification counts the top of the scale as 80% marks, not 100%. So 4.00 on a 4-point scale and 5.00 on a 5-point scale are both 80%.

What division is an SSC GPA of 2.75?

Second division. Since the notification of 2 March 2010, a GPA of 2.00 to below 3.00 is second division for SSC, HSC and equivalent exams.

Can I turn my SSC or HSC GPA into a percentage?

The notifications we read give an SSC or HSC GPA a division, not a percentage. The 80% rule is for a university CGPA.

Does the rule round the percentage?

We found no rounding rule in the notifications, so the calculator shows the exact percentage. A CGPA of 3.43 on a 5-point scale gives 54.88%.
