Disclaimer: Estimates only—actual ATAR depends on scaling in your year and state.
How we convert GPA to ATAR
- Normalise GPA to percentile rank using historical school reports.
- Map percentile to ATAR distribution curve released by UAC and state Tertiary Admission Centres.
- Adjust for cohort size and subject scaling (STEM vs humanities weighting).
GPA ↔ ATAR quick‑reference
| Unweighted GPA (4.0) | Approx. Percentile | Estimated ATAR |
|---|---|---|
| 4.00 | Top 1 % | 99.90+ |
| 3.90 | Top 5 % | 97.0‑99.0 |
| 3.70 | Top 15 % | 90‑95 |
| 3.50 | Top 25 % | 80‑89 |
| 3.00 | Top 50 % | 65‑79 |
| 2.50 | Below Average | < 65 |
State‑by‑state adjustments
ATAR scaling varies between Australian states. Key notes:
- NSW (UAC): HSC subjects receive scaling factors—Band 6 in Maths Ext 2 boosts percentile.
- VIC (VTAC): Study scores moderated; English/EAL compulsory, plus 10 % of 5th/6th subjects.
- QLD (QTAC): Uses ATAR not OP; internally assessed + external exam (25 %) weights.
- WA, SA/NT, TAS, ACT: Slight variations but overall percentile mapping similar.
How to boost your ATAR
- Select scalable subjects you can excel in—advanced maths, physics, chem.
- Focus on externals—they often count 40‑50 % of final score.
- Balance workload: quality over quantity—four Band 6 scores beat six Band 4s.
- Use past papers to master exam timing & command terms.
Frequently Asked Questions
Is this calculator officially endorsed?
No—NUM8ERS provides an estimate only. Always consult your state TAC for official conversion.
Does weighted GPA change the result?
Yes. If your school provides weighted GPA, enter the unweighted 4.0 scale for best accuracy.
How accurate is the estimate?
Within ±1.5 ATAR points for most students, assuming average cohort scaling.
