What HEC actually publishes
Two HEC documents matter here. The first is the Policy Guidelines for Implementation of Uniform Semester System in Higher Education Institutions of Pakistan. Section 13.1 sets out a “fractionalized grading system” and says the equivalence of GPA/CGPA and percentage below is recommended for adoption. A note under the table says a student with any CGPA is given the minimum percentage of the matching band, so a 3.00 CGPA is 71%.
The second is HEC Notification No. 8-65/HEC/A&A/2007 of 14 January 2008. It records that universities use different formulas to convert CGPA into percentage, directs that CGPA be used for semester-system graduates, and states that HEC will no longer carry out CGPA-to-percentage conversion itself.
HEC recommended equivalence (section 13.1)
| Grade | Grade points | Percentage | Percentage this calculator shows |
|---|---|---|---|
| A | 3.67–4.00 | 85 and above | 85% |
| A- | 3.34–3.66 | 80–84 | 80% |
| B+ | 3.01–3.33 | 75–79 | 75% |
| B | 2.67–3.00 | 71–74 | 71% |
| B- | 2.34–2.66 | 68–70 | 68% |
| C+ | 2.01–2.33 | 64–67 | 64% |
| C | 1.67–2.00 | 61–63 | 61% |
| C- | 1.31–1.66 | 58–60 | 58% |
| D+ | 1.01–1.30 | 54–57 | 54% |
| D | 0.10–1.00 | 50–53 | 50% |
| F | 0.00 | Below 50 | Below 50% |
HEC's bands leave small gaps between printed ranges, for example between 3.00 (end of B) and 3.01 (start of B+). The document does not say how to treat a CGPA such as 3.005. This calculator keeps such a value in the lower band, because it has not reached the next band's starting point, so 3.005 shows 71%. CGPAs are normally reported to two decimals, so this rarely matters.
HEC table vs linear conversion
| CGPA (4.0) | HEC table | Linear CGPA ÷ 4 × 100 |
|---|---|---|
| 3.80 | 85% | 95% |
| 3.50 | 80% | 87.5% |
| 3.00 | 71% | 75% |
| 2.50 | 68% | 62.5% |
| 2.00 | 61% | 50% |
For a passing CGPA of 2.00 or more, the two methods disagree by up to 15 points (4.00 is 85% in the HEC table and 100% linearly). Neither is binding on every university, which is why the transcript figure always wins. Below a CGPA of about 2.85 the HEC table gives the higher figure.
The linear formulas
4.0 scale: Percentage = (CGPA ÷ 4.0) × 100. 5.0 scale: Percentage = (CGPA ÷ 5.0) × 100. These are simple proportions, not HEC rules. HEC recommends a 0.00 to 4.00 scale for all universities, so a 5.0 scale is now rare.
How to use this calculator
- Keep “HEC recommended table” selected, or switch to a linear option if your university uses it.
- Enter your CGPA as shown on your transcript.
- Read the percentage and the HEC band it comes from.
- Use the university lookup panel for notes on your institution.
Common mistakes
Calling the linear figure “the HEC formula”. CGPA ÷ 4 × 100 is not in HEC’s grading guidelines. If a form asks for an HEC-based figure, the section 13.1 table is the HEC source.
Mixing up the 4.0 and 5.0 scales. A 3.5 on a 5.0 scale is not the same as 3.5 on a 4.0 scale. Check the scale printed on your transcript.
Treating a converted percentage as your result. Your transcript shows a CGPA. Any percentage is a calculated equivalent, and admission offices may ask for the transcript itself.

Disclaimer: The default result follows the equivalence table HEC recommends in its Uniform Semester System policy guidelines (section 13.1), which is a recommendation, not a binding rule. Universities may use their own conversion, relative grading, or rounding. The figure on your transcript or from your registrar is the one to use on formal applications.
