In Pakistan, the official way to convert a CGPA to a percentage is HEC's grade-band rule: your CGPA is assigned the minimum percentage of the grade band it falls into. HEC's own worked example makes it concrete — a 3.00 CGPA equals 71%. That is why the popular "CGPA × 25" shortcut (which would call 3.00 a 75%) is only a rough approximation, not the real figure.
The official HEC rule
HEC does not use a flat multiplier. Under its Policy Guidelines, a CGPA is converted by locating its grade band in the §13.1 table and taking that band's minimum percentage:
CGPA 3.34 → A− band (3.34–3.66) → 80%
CGPA 3.67 → A band (3.67–4.00) → 85%

CGPA-to-percentage table
Reading the §13.1 band table as a conversion — find the row your CGPA sits in and take the percentage:
| CGPA range | HEC minimum percentage |
|---|---|
| 3.67 – 4.00 | 85% |
| 3.34 – 3.66 | 80% |
| 3.01 – 3.33 | 75% |
| 2.67 – 3.00 | 71% |
| 2.34 – 2.66 | 68% |
| 2.01 – 2.33 | 64% |
| 1.67 – 2.00 | 61% |
| 1.31 – 1.66 | 58% |
| 1.01 – 1.30 | 54% |
| 0.10 – 1.00 | 50% |
Bands per the HEC Policy Guidelines (§13.1). A CGPA below 0.10 corresponds to F (below 50%).
Why "CGPA × 25" is wrong
The "CGPA × 25" method treats the scale as perfectly linear: CGPA ÷ 4 × 100. On that shortcut a 3.00 becomes 75% and a 3.50 becomes 87.5%. But HEC's band table is not linear near the middle — a 3.00 is the floor of the B band, which HEC fixes at 71%, not 75%. The gap is real and it matters: quoting 75% where HEC says 71% overstates your result by four points on any form that expects the official figure.
Worked conversions
- CGPA 3.80 → A band (3.67–4.00) → 85%.
- CGPA 3.40 → A− band (3.34–3.66) → 80%.
- CGPA 3.20 → B+ band (3.01–3.33) → 75%.
- CGPA 3.00 → B band (2.67–3.00) → 71% (HEC's own example).
- CGPA 2.50 → B− band (2.34–2.66) → 68%.
You don't have to look these up by hand — the CGPA Calculator for Pakistan shows the HEC percentage next to your CGPA as you enter your semesters, and the percentage ↔ GPA converter handles single-value conversions with each formula shown.
Which figure to use, and when
Three figures can all be "correct" depending on who's asking:
- Your transcript's printed percentage. The safest for any official Pakistani use — employers, HEC attestation, local admissions. If your university prints an equivalence, that is the number of record.
- The HEC band figure (the table above). Use it when you have only a CGPA and need HEC's standard percentage — for example, filling a form that asks for both.
- Your raw CGPA. Best for US and Gulf universities, which are already on the 4.0 scale and read the CGPA directly. See what is a good CGPA in Pakistan for the thresholds those programs look for.
Where the exact conversion varies by institution, use your own university's official scheme — browse Pakistan university GPA calculators and pick your school. The HEC grading system guide explains where the band table comes from.
