In short: to convert a percentage to a GPA on the 4.0 scale, divide by 100 and multiply by 4, so 75% is a 3.0 GPA. The 5.0 scale works the same way with a 5 in place of the 4. India's 10-point scale is the exception: it has two competing conventions, and they disagree by 0.39 points at 75%.
What is the percentage to GPA formula?
Divide your percentage by 100, then multiply by the top of the scale you need. On the 4.0 scale that is (percentage ÷ 100) × 4, and on the 5.0 scale it is × 5. India's 10-point scale is the exception, where the divisor your university publishes decides the answer.
Every one of these is a rescaling rather than a recalculation. Your percentage is not recomputed from your courses; it is simply stretched or compressed onto a different range, which is why the arithmetic is so simple and why the result is an estimate rather than an official figure.
| Scale | Formula | Example |
|---|---|---|
| 4.0 (US, Canada, Australia) | GPA = (percentage ÷ 100) × 4 | 75% → 3.00 |
| 5.0 | GPA = (percentage ÷ 100) × 5 | 75% → 3.75 |
| 10-point (AICTE convention) | CGPA = percentage ÷ 9.5 | 75% → 7.89 |
| 10-point (÷ 10 convention) | CGPA = percentage ÷ 10 | 75% → 7.50 |
The 4.0 conversion is the one most students need, because it is what US, Canadian and Australian application forms ask for. Note what happens at 80%: it converts to 3.20 on the 4.0 scale and exactly 4.00 on the 5.0 scale. The same performance reads as a strong B average under one scale and as a perfect score under the other, so a GPA reported without its scale is not information.

Why do two calculators give you two different 10-point answers?
Convert 75% to a 10-point CGPA on two different sites and you will often get two different numbers. One returns 7.89, the other 7.50. Neither is a bug.
The split is a genuine disagreement between conventions. The AICTE-derived rule divides a percentage by 9.5, which is the reverse of the ×9.5 multiplier most Indian engineering colleges use to publish a percentage from a CGPA. A second group of universities (VTU, Anna University and MAKAUT among them) works on a straight ÷10. Both are published rules; they simply belong to different institutions.
| Percentage | ÷ 9.5 (AICTE) | ÷ 10 (VTU, Anna, MAKAUT) | Difference |
|---|---|---|---|
| 60% | 6.32 | 6.00 | 0.32 |
| 70% | 7.37 | 7.00 | 0.37 |
| 80% | 8.42 | 8.00 | 0.42 |
| 90% | 9.47 | 9.00 | 0.47 |
The gap widens as your score rises, from 0.32 at 60% to 0.47 at 90%. That is enough to move you across a scholarship or placement threshold written as a CGPA, so pick the convention your own university publishes rather than the one that flatters your transcript. If your marksheet shows both a percentage and a CGPA, dividing one by the other tells you which camp you are in.

What does a converted GPA leave out?
A real GPA is a credit-weighted average: each course's grade point is multiplied by that course's credits before anything is averaged. A percentage on an Indian marksheet has usually already flattened that weighting into a single aggregate figure. Rescaling it to 4.0 cannot put the weighting back.
The consequence is easy to miss. Two students with an identical 75% convert to the same 3.0 here, but if one earned their strongest marks in heavy lab and project courses and the other earned theirs in light electives, their actual credit-weighted GPAs differ. The conversion has no way of knowing.
This is why an admissions office reads your transcript rather than the number you typed into a form. Where you have the underlying data, the honest route is to compute the GPA from your course list instead of rescaling an aggregate. Where you only have the percentage, this page gives you a defensible estimate, but label it as one.
What do applications in each country ask for?
Check which unit the form actually wants before converting anything. A converted GPA is the right answer in some systems and the wrong one in others, and several countries would rather see your original percentage with its scale named. The table below sorts it by destination.
| Destination | Usually asks for | Watch out for |
|---|---|---|
| United States | GPA on a 4.0 scale, plus the transcript itself | Most portals accept a self-reported conversion at application stage |
| United Kingdom | Percentage or degree class, not a GPA | Converting to GPA can lose information rather than add it |
| Canada | GPA, scale varies by province and institution | Check whether the scale is 4.0, 4.3 or 9.0 before converting |
| Germany | Modified Bavarian formula applied to your percentage | A 4.0-scale GPA is usually the wrong input entirely |
| Australia | GPA on a 4.0 or 7.0 scale | The 7.0 scale is common and is not interchangeable with 4.0 |
Specific admission thresholds are set programme by programme and change year to year, so treat any single cut-off figure you read online (here or anywhere else) as unverified until you find it on the department's own page.
When do you need a credential evaluation instead?
A self-converted GPA is fine for filling in an application field. It is usually not enough for an admission decision, a professional licence or an immigration file. For those, institutions ask for a credential evaluation from an agency such as World Education Services, which reviews your transcript course by course and issues its own assessment.
The important distinction is what the evaluator works from. This page rescales one aggregate number. An evaluation reads every course, its credits and its grade, and applies its own methodology to the whole record. The two will not always agree, and where they disagree the evaluation is the document that counts. Check the receiving institution's requirements early, since evaluations take weeks and carry a fee.
Converting the other way: GPA to percentage
Reverse the arithmetic. On the 4.0 scale, percentage = (GPA ÷ 4) × 100, so a 3.0 GPA returns 75%. On the 10-point scale, multiply by 9.5 or by 10 depending on your university's convention. The calculator at the top of this page handles both directions, so switch to the GPA → % tab and enter your GPA instead.

Not the calculator you need?
All four GPA calculators on this site answer a different question. The one you want depends on what you are starting from:
- If you have a list of courses, each with credits and a letter grade, use the GPA calculator for course grades and credits.
- If you have one 10-point CGPA already on your marksheet, use the CGPA to GPA calculator (10-point to 4.0).
- If you have several semesters, each with its own GPA and credit total, use the multi-semester CGPA calculator with GPA.
