Enter your GPA · get a transparent ATAR-equivalent estimate · compare against course cut-offs
Indicative only — cut-offs change annually and vary by institution. Always verify directly with the university’s international admissions office.
This calculator provides estimates only using a transparent percentile-based formula. There is no official Australian body that publishes a GPA-to-ATAR table. Always confirm your standing directly with each university’s international admissions office. This tool is not affiliated with any Australian university or tertiary admissions centre.
Use our free GPA to ATAR Calculator to get an indicative Australian ATAR equivalent for your international Grade Point Average. Built for students, parents, and counsellors comparing US/Canada (4.0), UK-style (4.3), Australian university (7.0), and CGPA (10.0) scales against the ATAR system — with full transparency about how the conversion works and, just as importantly, its limits.
The ATAR (Australian Tertiary Admission Rank) is a number from 0.00 to 99.95 that ranks a student’s academic achievement against the entire same-age cohort in Australia. GPA (Grade Point Average) is something different: an absolute average of the grades a student achieved across their subjects, on a scale set by their own school or country.
Because international students don’t sit the Australian Year 12 curriculum, they don’t receive an ATAR directly. Universities need some way to gauge how a GPA-holding applicant compares to ATAR-based domestic applicants — which is where GPA-to-ATAR conversion tools, including this one, come in. They are planning aids, not official scores.
This is the most important thing to understand before using any GPA-to-ATAR tool — including this one:
It helps to understand how a real, scaling-based ATAR system works, so you can see why GPA conversion is fundamentally different. In Queensland’s QCE system, for example, QTAC applies inter-subject scaling to raw subject scores, sums the best five scaled results into a Tertiary Entrance Aggregate (TEA), and ranks all eligible students into 2,000 ATAR bands. This works because every student sits comparable subjects assessed under one shared curriculum body (QCAA). GPA has no equivalent shared curriculum or scaling process across the thousands of schools and countries it’s drawn from — which is exactly why no single conversion table can be made official.
The table below shows widely referenced approximate benchmarks for the US/Canadian 4.0 scale. These figures are used informally by some universities and education consultants as general guidance — they are not official and can vary noticeably between institutions.
| GPA (4.0 scale) | Approx. ATAR Equivalent | Indicative Tier |
|---|---|---|
| 4.00 | 99.00 – 99.95 | Exceptional |
| 3.90 | 97 – 99 | Exceptional |
| 3.80 | 95 – 97 | Excellent |
| 3.70 | 92 – 95 | Excellent |
| 3.50 | 88 – 91 | Strong |
| 3.30 | 84 – 87 | Strong |
| 3.00 | 78 – 82 | Competitive |
| 2.80 | 72 – 76 | Competitive |
| 2.50 | 63 – 67 | Developing |
| 2.00 | 48 – 52 | Developing |
Note: These figures are illustrative only. Always check the specific university’s published international equivalency table — see the UAC IB conversion page for an example of what a genuinely official conversion looks like, by contrast.
Your score ratio is simply your GPA expressed as a fraction of the maximum on your selected scale (e.g. 3.5/4.0 = 87.5%). The calculator then applies a non-linear curve — because the ATAR compresses heavily near the top (the gap between ATAR 95 and 99.95 is much larger in percentile terms than the gap between 50 and 55), a straight linear conversion would understate how competitive very high GPAs really are.
Any GPA-to-ATAR estimate — including this one — can’t fully account for:
For this reason, always treat your estimated ATAR equivalent as a planning guide, not a guarantee. For genuinely official conversions, see the UAC IB-to-ATAR table, and for GPA specifically, contact your target university’s international admissions office.
No. Unlike the IB Diploma, which has an official UAC-published table used identically by every Australian tertiary admissions centre, there is no government-mandated GPA-to-ATAR table. Each university independently assesses international GPAs against its own published equivalency standards.
As a rough guide, a GPA of approximately 3.5–3.7 on a 4.0 scale is sometimes informally treated as broadly comparable to an ATAR in the high-80s to low-90s. This varies meaningfully between institutions and grading systems — always check the specific university’s own international equivalency table.
The IB Diploma has one global curriculum with consistent grade boundaries shared with UAC, enabling a precise table. GPA comes from thousands of different schools worldwide with no shared grading standard, making a single universal conversion mathematically unreliable. That’s why Australian universities assess GPA case by case.
International applicants generally don’t apply through a state Tertiary Admissions Centre such as UAC, VTAC, QTAC, SATAC, or TISC, since those primarily process domestic ATAR and IB pathways. GPA-based applicants typically apply directly to a university’s international admissions office, which assesses transcripts against its own equivalency standards.
No — treat it as a research and planning tool only. For an actual application, universities will independently assess your official transcript against their own equivalency standards, which this tool cannot replicate exactly.
Select the closest matching scale from the tabs (4.0, 4.3, 7.0, or 10.0). If your scale doesn’t match any of these, convert your GPA to the nearest equivalent fraction of its maximum first, then enter the closest matching value.
