About GPA to Percentage Calculator (SSC and HSC)
This GPA to percentage page explains how to estimate marks from an SSC or HSC GPA, and why a GPA only gives a range and not an exact percentage. It is free, needs no sign-up and runs in your browser, so nothing you enter is uploaded.
A GPA averages grade points, and each grade covers a band of marks, so many different mark sets give the same GPA. An A is 70 to 79 and an A+ is 80 to 100, which is a wide range. The best you can do is an estimate. Two methods are common: read the GPA against the lowest mark of each grade (the grade band method), or take GPA divided by 5 times 100 (the linear method).
They disagree. For a GPA of 4.50 the grade band method gives 75 and the linear method gives 90. This calculator has no GPA to percentage field, but the CGPA calculator on Ulkaa Tool does both methods under CGPA to %, with a scale for SSC and HSC. Quote the method with the number, and use your marksheet marks when you have them.
How to use GPA to Percentage Calculator (SSC and HSC)
- Pick your system in the tabs: SSC, HSC, Dakhil, Alim, US high school or US college.
- For a Bangladesh exam, choose a grade for every subject. Add or remove rows to match your group, and count a two-paper subject such as Bangla or English once, with its combined grade. Or switch on marks entry and type the mark out of 100 for each subject.
- Switch the 4th subject on or off, and choose its grade. Only the points above 2.00 count towards the GPA.
- For US courses, enter the credits and the letter grade of each course. In high school mode also choose Regular, Honors or AP / IB for each course.
- Read the result. Bangladesh tabs show the GPA with and without the 4th subject and a letter grade. US tabs show the GPA, or the weighted and unweighted pair.
Features
- SSC, HSC, Dakhil and Alim on the 5.00 board scale, with the number of starting subject rows matching each exam and rows you can add or remove.
- 4th subject support: points above 2.00 are added, the GPA is capped at 5.00, and an F in the 4th subject does not make the GPA zero.
- GPA with and without the 4th subject shown together, and a letter grade for the result.
- The F rule: an F in any main subject makes the GPA 0.00.
- Marks entry: type a mark out of 100 and the calculator finds the grade and its points.
- GPA shown to two decimals without rounding up, the way the boards print it, so 4.996 shows as 4.99.
- US high school GPA, weighted (+0.5 Honors, +1.0 AP or IB) and unweighted, weighted by credits.
- US college GPA on the 4.0 scale or the 4.3 scale where A+ is 4.3, with typical Latin honors.
- Plus and minus letters and decimal credits for US courses.
Worked examples
GPA 4.50 on the 5.00 scale gives 75.00 percent by grade band, 90.00 percent linear
GPA 5.00 on the 5.00 scale gives 80.00 percent by grade band (the A+ floor of 80), 100.00 percent linear
The band method gives the lowest mark that earns this GPA, not your actual marks.
Marks behind each SSC and HSC grade
| Letter | Grade point | Marks (%) |
|---|---|---|
| A+ | 5.00 | 80 to 100 |
| A | 4.00 | 70 to 79 |
| A- | 3.50 | 60 to 69 |
| B | 3.00 | 50 to 59 |
| C | 2.00 | 40 to 49 |
| D | 1.00 | 33 to 39 |
| F | 0.00 | 0 to 32 |
Privacy: how it works
- Subjects, marks, grades and credits are processed by code in your browser tab. Nothing is sent to Ulkaa or anyone else, and nothing is stored, so closing the tab clears the page.
Tips
- If a university asks for your GPA, quote the figure printed on your marksheet and use this page to understand it.
- Count a two-paper subject once, with its combined grade, so the number of main subjects matches the board.
- In US high school mode, check whether your school caps weighted GPA at 5.0 or weights only some grades, and adjust your reading of the result.
Frequently asked questions
Is it really free?
Yes. There is no price, no trial and no credit card. Ulkaa Tool does the work with your own device, so there is no server bill to pass on to you.
Do I need an account?
No. There is no sign-up and no login. Open the page and use it. An Ulkaa account is not needed for anything on this tool.
Does it run in my browser?
Yes. Your grades are processed by code running in your browser tab, on your own device.
Is my data uploaded?
No. Your grades are never sent to Ulkaa or to anyone else. You can check this yourself by watching the Network tab in your browser developer tools while you use the tool.
Can I get my exact percentage from my GPA?
No. A grade covers a range of marks, so a GPA only gives an estimate. Your marksheet lists the actual marks.
Which method is right?
Neither is official. The grade band method is closer to the marks, and the linear method is a simple proportion. Say which one you used.
