How to convert CGPA to percentage
On a 4.0 scale, percentage = CGPA ÷ 4 × 100, which is the same as CGPA × 25: a CGPA of 3.2 is 80%. If your transcript prints its own conversion, use that instead, because HEC does not set one formula for every university.
The short version
- Check your scale. Most Pakistani universities use 4.0; some use 5.0.
- Divide your CGPA by the scale. 3.2 ÷ 4 = 0.8.
- Multiply by 100. 0.8 × 100 = 80%.
- Check your transcript. If it has a conversion key, use the key's figure for official forms.

Quick conversions (4.0 scale)
| CGPA | Percentage |
|---|---|
| 4.00 | 100% |
| 3.75 | 93.75% |
| 3.50 | 87.5% |
| 3.25 | 81.25% |
| 3.00 | 75% |
| 2.50 | 62.5% |
| 2.00 | 50% |
To go the other way, CGPA = percentage ÷ 100 × 4: 75% is 3.0 and 60% is 2.4.
Why your university's figure may differ
The straight proportion treats the 4.0 scale as a simple stretch of 0-100%. Many universities grade on bands instead - an A from 85%, say - and some print a table on the transcript that maps grade points back to percentages. Their numbers can differ by a few percent from CGPA × 25. When an application says "percentage as per university", use the university's table; when it just asks you to convert, CGPA × 25 is the accepted method.
Calculating CGPA from semesters
CGPA is credit-weighted. Multiply each semester's GPA by its credit hours, add those up, and divide by the total credit hours:
The simple average of the three GPAs is 3.47, which is close but not what the transcript shows, because the first semester carried more credit hours. On a 4.0 scale, a 3.45 CGPA is 86.25%.
Other scales
The same idea works for any scale: divide by the scale and multiply by 100. A 4.2 out of 5.0 is 84%; an 8.0 out of 10 is 80%. Do not mix scales - a 3.2 on a 5.0 scale is 64%, not 80%.
Common mistakes
- Averaging semester GPAs. A plain average ignores credit hours; always weight by them, as above.
- Rounding too early. The exact CGPA in the example is 3.4529, which converts to 86.32%. Rounding to 3.45 first gives 86.25%. Use the figure your transcript prints, and round only the final percentage.
- Using the wrong multiplier. Multiplying by 10 or 20 only works on 10-point or 5-point scales. On a 4.0 scale the multiplier is 25.
- Treating a percentage as a grade. 80% from a CGPA conversion is not the same as 80% marks in a board exam; when an application compares them, follow the instructions it gives.
