Bangladeshi universities grade on a 4.0 scale where the letters step down in quarters and halves: A+ is 4.00, A is 3.75, A- is 3.50, and it keeps falling to F at zero. This calculator takes your courses with their credit hours, matches each grade to its point value, and works out a cumulative CGPA across everything you have typed in.
It is for students at public and private universities in Bangladesh, and for anyone passing a Bangladeshi transcript to an admissions office somewhere else. You start with five rows, you can stretch to sixty, and the result comes with a breakdown table showing exactly what each course contributed to the total.
Calculate your university CGPA on the Bangladesh 4.0 scale. Add each course with its letter grade and credit hours, and this works out your cumulative GPA.
The grade scale it uses
- A+ = 4.00
- A = 3.75
- A- = 3.50
- B+ = 3.25
- B = 3.00
- B- = 2.75
- C+ = 2.50
- C = 2.25
- D = 2.00
- F = 0.00
That is the table most Bangladeshi institutions work from and it is the one sitting in the dropdowns. Notice the gap between an A+ and an A is only 0.25, so one average course drags you less than you would fear. D at 2.00 is generally treated as the lowest passing grade, while an F earns nothing and still keeps its credit hours in the denominator, which is why one failed course stings twice.
How the CGPA is worked out
CGPA = total grade points ÷ total credit hours
Every course multiplies its grade point by its credit hours, you add those products together, then divide by the total credits on the table. That makes it a credit weighted mean, so a 4-credit course moves your CGPA noticeably harder than a 1-credit course carrying the same letter. The result box spells the formula out with your own numbers in it, then prints a row by row table of course, grade, credits and points so nothing is hidden.
A worked example
Five courses, sixteen credit hours between them:
- Physics – A+ (4.00) × 3 credits = 12.00 points
- Chemistry – A (3.75) × 3 credits = 11.25 points
- Calculus – B+ (3.25) × 4 credits = 13.00 points
- English – B (3.00) × 3 credits = 9.00 points
- History – C+ (2.50) × 3 credits = 7.50 points
Points add to 52.75 and credits add to 16, so 52.75 ÷ 16 = 3.296875 and the panel reports CGPA: 3.30 / 4.00 with the line “Across 16 credit hours your CGPA is 3.30 on the Bangladesh 4.0 scale.” Swap History up to an A- and the same term reads 3.48, which tells you a single 3 credit grade is worth roughly 0.18 of CGPA on its own.
Mistakes that hold the calculation up
The one that catches everybody: you get five rows but you only filled two. The empty rows still carry the default A+ with no credit hours, and the calculator stops with “Credit hours must be greater than zero” until you either fill them in or press Remove on the ones you do not need. Clear the spare rows first, then work down the list. You cannot drop below one row, and past sixty courses the add button locks and the hint says you have hit the maximum.
Beyond that, do not read 3.30 as 33 percent or as 83 percent. Different institutions convert CGPA to percentages with their own formulas, so if a form wants a percentage you need the conversion your university actually publishes. And if your department replaces a retake grade instead of averaging both attempts, enter the attempt that counts, because this tool only knows what you type into it.

Frequently asked questions
Is this the same as the American 4.0 scale?
No. The letter bands sit at different percentages and the steps here are quarters and halves rather than a straight ladder. Your transcript follows its own scale, so grade against that and not against a converted US number.
What CGPA do I need to graduate?
A lot of programmes ask for 2.50 out of 4.00 overall and some ask for 2.00, but the regulations printed by your department are the ones that count. Check those rather than trusting a figure copied off the internet.
How do I turn CGPA into a percentage?
Your university publishes its own formula and most of them differ slightly, so the official conversion is the one an employer will recognise. For a rough estimate in the meantime, the CGPA to percentage converter on this site does the job.
Does an F count against me twice?
It scores zero points and its credit hours still sit in the denominator, so you lose the marks while keeping the weight. Removing a failed course only helps if your institution lets you drop it, and if it stays on the transcript it stays in the maths.
Can I put several semesters into one list?
Yes, since CGPA is cumulative. Enter every course you have completed if you want your overall standing, or restrict the list to one term if you only want that term’s average on its own.
Why does the result say / 4.00?
Because 4.00 is the ceiling of this scale. An A+ tops out at 4.00, so no mix of courses can ever push the printed figure above it.
