HEC CGPA and Board GPA to Percentage, Explained
Convert a university CGPA or a matric/intermediate board GPA into a percentage, using HEC's and the boards' own published tables, not just a guessed formula.
About CGPA to Percentage Calculator
This calculator converts a CGPA or GPA into a percentage for two separate situations, switched with the buttons at the top: a Pakistani university CGPA (the 4.0 or 5.0 scale used after your bachelor's or master's semesters), and a matric or intermediate board GPA (the 0-to-5 scale BISE and FBISE have used for school results since 2023). They are different systems with different tables, so the tool never mixes them.
In University mode, enter your CGPA directly, or build it from each semester's SGPA and credit hours if you have not added them up yet. The result shows two figures side by side: a quick estimate using the common CGPA × 25 shortcut (CGPA × 20 on a 5.0 scale), and a second figure from HEC's own 2008 grading-band table, which is not a formula at all — it assigns the minimum percentage of whichever band your CGPA falls into. The two numbers genuinely differ, and the tool shows both rather than picking one, because different universities and purposes expect different answers. The multiplier is also editable, since some universities use 24 instead of 25.
In Board mode, enter your GPA to get a percentage, or a percentage to get the matching grade and GPA. A percentage-to-grade lookup is exact, straight from the published table. A GPA that matches one of the board's ten official grade points (5.0, 4.7, 4.3, 4.0, 3.7, 3.3, 3.0, 2.0, 1.0 or 0) also gets an exact band. An overall GPA in between, such as 3.85, is estimated by interpolating between the two nearest published points, and the tool says plainly when it has done this, because boards do not publish a formula for an averaged overall GPA.
How to use CGPA to Percentage Calculator
- Choose University (CGPA) or Matric / Intermediate (Board) at the top, depending on which result you have.
- University mode: pick your 4.0 or 5.0 scale, check the multiplier (25 or 20 by default — edit it if your university is known to use a different one), then either type your CGPA directly or switch to "Build from semesters" and add each semester's SGPA and credit hours.
- Click Convert to Percentage to see the quick estimate, the HEC band figure and your letter grade, with the full HEC table below and your row highlighted.
- Board mode: pick GPA → Percentage or Percentage → GPA, type your number, and click Convert. The full board table is shown below for reference.
- To work backwards from a percentage you are aiming for, use the "Find Required CGPA" field in University mode, or the Percentage → GPA direction in Board mode.
Tips for best results
- Treat every result here as an estimate for your own planning, not an official document. For a degree, scholarship, job or visa application, request the official percentage or conversion letter from your university's controller of examinations or your board, since that is the figure that counts.
- If your transcript already states a percentage directly, use that instead of converting your CGPA — it is more accurate than any formula or band table.
- Check your university's own academic policy or handbook for its stated multiplier before trusting the quick estimate for anything important; 24 and 25 are both in real use.
- The HEC band table applies to the 4.0 scale only, because that is what HEC's own 2008 document defines. On a 5.0 scale, rely on the quick estimate and your university's own policy instead.
- For matric or intermediate, an interpolated overall-GPA percentage is a reasonable estimate but not exact. If you need an exact mark, your board's result card or gazette often lists the actual marks obtained per subject.
Frequently asked questions
Why does this tool show two different percentages for my CGPA?
Because there are two different ways universities report it. The quick estimate is the common CGPA × 25 shortcut. The HEC column instead uses the Higher Education Commission's own 2008 grading-band table, which assigns the minimum percentage of your grade band rather than a straight multiplication — so a 3.00 CGPA reads as 71% there, not 75%. They are both legitimate; your university may use either, or something else entirely.
Does HEC still issue official CGPA-to-percentage conversion letters?
No. HEC stopped issuing conversions itself under Notification No. 8-65/HEC/A&A/2007 (14 January 2008), the same notification that published the grading-band table this tool uses. For a degree, scholarship or visa application, request the official conversion letter from your university's registrar or controller of examinations.
My university uses CGPA × 24, not × 25 — can I still use this?
Yes. The multiplier field is editable; change it from 25 to 24, or whatever your university's policy states, before converting. Check your transcript, academic handbook or registrar's office if you are not sure which multiplier applies to you.
What's the difference between the two scales, 4.0 and 5.0?
Most Pakistani universities (NUST, FAST-NUCES, COMSATS, UET, LUMS, Punjab University, among others) grade on a 4.0 scale. A handful of programmes, including some at the University of Karachi, use a 5.0 scale instead. Check your transcript's maximum CGPA to tell which one applies to you; the HEC band table in this tool only covers the 4.0 scale, since that is what HEC's own document defines.
How is CGPA worked out from several semesters?
Each semester has its own SGPA (semester grade point average) and a number of credit hours. The overall CGPA is a weighted average: multiply each SGPA by that semester's credit hours, add the results together, then divide by the total credit hours across all semesters. Switch to "Build from semesters" and the tool does this for you.
Is the matric/intermediate GPA system the same as a university CGPA?
No, and they should not be converted with the same formula. Since 2023, Pakistani boards (BISE and the Federal Board, FBISE) report matric and intermediate results as a GPA on their own 0-to-5 scale with its own grade table, separate from any university's 4.0 or 5.0 scale. This tool treats them as two separate modes for that reason.
My overall board GPA is something like 3.85 — why is that an estimate?
Boards publish an official percentage band for each subject's letter grade (for example, a B++ grade is 80-84%, worth 4.0), but they do not publish a formula for the overall GPA average across all your subjects, because that average can land on any decimal. This tool estimates it by interpolating between the published grade points and says so on the result; for an exact figure, add up your actual subject marks or check your result card's own percentage, if it shows one.
Can I convert a percentage back into a CGPA or GPA?
Yes. Each mode has a reverse direction: in the university mode, enter a target percentage to see the CGPA it needs (using the quick-estimate multiplier); in the board mode, switch to "Percentage → GPA" to look up the matching grade and GPA band directly from the official table.
Are my numbers uploaded anywhere?
No. Every calculation runs in your browser with plain arithmetic; nothing you type is sent to a server.
Can I use this for an O-Level, A-Level or a foreign GPA?
Not directly. This tool is built around Pakistan's HEC university table and the BISE/FBISE board table specifically. A Cambridge or other foreign grade system uses different grade points and bands, so converting it here would give a misleading answer.
How to convert decimal to percent?
Multiply the decimal by 100 and add a percent sign: 0.85 is 85%, 0.075 is 7.5% and 1.2 is 120%. To go back, divide the percent by 100. A GPA or CGPA such as 3.4 is not a decimal fraction, so do not multiply it by 100; use this CGPA to percentage calculator, which applies the HEC or board tables.
