Convert CGPA to percentage — or percentage back to CGPA — instantly, using Pakistan's HEC-recognised methods. Pick a direction, enter your number, choose your scale (4.0 or 5.0), and get the official result with the exact formula shown. Free, no sign-up, works on any device.
How to use this calculator
- Choose your direction. Converting a transcript CGPA into a percentage for a CV? Keep "CGPA → Percentage". Filling a foreign application that asks for CGPA when your result card shows marks? Switch to "Percentage → CGPA (reverse)".
- Enter your number exactly as it appears on your transcript or result card.
- Select your grading scale. Almost every Pakistani university uses 4.0. Choose 5.0 only if your transcript states it.
- Choose a conversion method. Forward: Linear formula for job applications and everyday use, or HEC band table for the officially certified equivalent. Reverse: HEC reverse band formulas for the official number, or the linear shortcut to see how far the common estimate drifts.
- Click Convert. Your result appears instantly, with the exact method shown underneath so you always know which number you are looking at.
The formulas, explained
Linear formula
Percentage = (CGPA ÷ Maximum scale) × 100. On the 4.0 scale this simplifies to CGPA × 25. It treats every decimal of CGPA proportionally: 3.50 → 87.5%, 3.00 → 75%, 2.50 → 62.5%. This is the working standard for CVs, job portals, and informal comparisons.
HEC band-equivalence table
HEC's examination policy guidelines (section 13.1 of the Draft Policy Guidelines) print one grade-point value per percentage band and define the equivalence rule as the minimum of the band — HEC's own example: CGPA 3.00 → 71%. The CGPA boundaries in the table below follow the portal rounding convention (3.67 for HEC's printed 3.66, and so on) that universities' own calculators use; the percentage bands and assigned minimums are HEC's, verified against the primary document:
| Grade | CGPA band (portal convention) | Percentage band | Assigned % |
|---|---|---|---|
| A | 3.67–4.00 | 85+ | 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% |
Reverse formulas (percentage → CGPA, HEC official)
HEC defines separate piece-wise formulas for the reverse direction — one per percentage band. For any percentage: CGPA = base + (your % − band bottom) × multiplier.
| % band | 4.0: base / mult | 5.0: base / mult |
|---|---|---|
| 90–100 | 3.63 / 0.037 | 4.63 / 0.037 |
| 80–89 | 3.25 / 0.037 | 4.25 / 0.037 |
| 70–79 | 2.88 / 0.036 | 3.88 / 0.036 |
| 60–69 | 2.50 / 0.037 | 3.50 / 0.037 |
| 50–59 | 1.80 / 0.069 | 2.80 / 0.069 |
| 40–49 | 1.00 / 0.079 | 2.00 / 0.079 |
| Below 40 | % × 0.0248 | 1 + (% × 0.0248) |
Example: 87.5% on the 4.0 scale → band 80–89 → 3.25 + (87.5 − 80) × 0.037 = 3.53. The ÷25 shortcut would say 3.50 — close here, but it drifts by up to 0.4 CGPA at lower marks.

Worked examples
Linear: (3.67 ÷ 4.0) × 100 = 91.75%
HEC band: A band → 85%
Linear: (3.50 ÷ 4.0) × 100 = 87.5%
HEC band: A− band → 80%
Linear: (3.00 ÷ 4.0) × 100 = 75%
HEC band: B band → 71%
Linear: (2.50 ÷ 4.0) × 100 = 62.5%
HEC band: B− band → 68%
Linear: (4.50 ÷ 5.0) × 100 = 90%
HEC band: n/a (4.0 scale only)
Linear: (2.00 ÷ 4.0) × 100 = 50%
HEC band: C band → 61%
Frequently asked questions
Percentage = (CGPA ÷ 4.0) × 100 for everyday use. HEC's official band-equivalence table separately assigns each CGPA band the minimum of its percentage band (e.g. 3.50 → 80%). Use the linear formula on applications and the band figure for certified equivalence.
No. CGPA × 9.5 is India's CBSE formula for its 10-point school scale. On Pakistan's 4.0 scale it gives wrong results.
Because Pakistan genuinely has two recognised conversions: the proportional linear formula and HEC's band table. They answer different questions — the calculator shows you both so you can pick the right one.
Apply to your university's Controller of Examinations — HEC does not issue these directly. The university certifies your percentage from the official band table.
Almost certainly 4.0 — NUST, FAST-NUCES, LUMS, COMSATS, UET, NED, GIK, IBA Karachi and most public universities all use it. Check your transcript; if it says "out of 5.00", use the 5.0 option.
