Free ATAR calculator: enter up to 6 scaled study scores for a rough ATAR estimate from published aggregate tables. Unofficial.
Aggregate = best English + next 3 best subjects + 10% of the 5th and 6th best (the Victorian-style formula). The lookup uses published VTAC aggregate-to-ATAR table points as its shape; other states use different aggregates.
This ATAR calculator gives you a rough estimate of your Australian Tertiary Admission Rank from up to 6 scaled study scores (0–50 each). It builds an aggregate the Victorian way — best English subject plus your next three best plus 10% of the fifth and sixth — then maps it through published aggregate-to-ATAR table points. This is a rough estimate only: the official ATAR is computed by state authorities (VTAC, UAC, QTAC and others) with subject scaling that changes every year.
The Australian Tertiary Admission Rank (ATAR) is a number from 0 (well, technically below 30 is reported as "less than 30") to 99.95 that ranks you against your entire age cohort. An ATAR of 90.00 means you performed better than 90% of students — it is a rank, not a percentage mark. Universities use it (alongside prerequisites and selection ranks) to allocate course offers.
Each state computes it differently. In Victoria, VTAC takes your scaled study scores — raw marks adjusted up or down for subject difficulty and cohort strength, a process called scaling that changes every year — and builds an aggregate: your best English subject + your next 3 best subjects + 10% of your 5th and 6th best (maximum 210). That aggregate is then mapped to an ATAR using that year's official conversion table, so the same aggregate can mean a slightly different ATAR from year to year.
Aggregate = English + best 3 others + 0.1 × (5th + 6th best)
ATAR estimate: the highest published table ATAR whose minimum aggregate is at or below yours (using VTAC's 2024 aggregate-to-ATAR table points — e.g. 154.85 → 90.00, 169.54 → 95.00, 183.84 → 98.00, 192.07 → 99.00).
Worked example. Scaled scores: English 40, plus 38, 36, 35, 34, 32.
Say your dream course lists a 95.00 selection rank. Working backwards through the table, you need an aggregate of at least 169.54. With English at 42, you'd need roughly: 42 + (next three averaging ~38) + 10% of ~70 ≈ 42 + 114 + 7 = 163 — short. That tells you immediately that you need either stronger top-four subjects (aim for ~40s) or a higher English score. Running these scenarios before exam season is far more useful than guessing — but always confirm final cutoffs with the official VTAC/UAC/QTAC publications, since scaling shifts yearly.

This page hosts a free ATAR Calculator that estimates an Australian Tertiary Admission Rank from up to 6 scaled study scores (0–50). Key facts: the Victorian-style aggregate is best English + next 3 best subjects + 10% of the 5th and 6th best (max 210); the estimate maps the aggregate through published VTAC 2024 aggregate-to-ATAR table points (e.g., 154.85 → 90.00, 169.54 → 95.00, 183.84 → 98.00). Official ATARs are computed by state tertiary admissions centres (VTAC, UAC, QTAC) with annually changing subject scaling — this tool is a rough, unofficial estimate only.
Each state differs slightly. In Victoria, VTAC scales your study scores for subject difficulty, then builds an aggregate: your best English subject + your next 3 best subjects + 10% of your 5th and 6th best (max 210). That aggregate is converted to an ATAR (max 99.95) using that year's official table. NSW (UAC), Queensland (QTAC) and other states use their own aggregation rules.
Using VTAC's 2024 table as a guide, an aggregate of about 154.85 was the minimum for a 90.00 ATAR, 169.54 for 95.00, and 183.84 for 98.00. These thresholds shift each year with cohort performance and scaling, so treat them as indicative only.
Enter scaled study scores (0–50 after VTAC/UAC/QTAC scaling) for the best estimate. Raw exam marks ignore scaling — hard subjects scale up and easier ones scale down — so raw scores will misstate your aggregate and ATAR.
Yes — 99.95 is the maximum ATAR, awarded to the students with the very highest aggregates (around 210+ in Victoria). It means you are ranked in the top 0.05% of your age cohort nationally.
It is a rough planning estimate, not an official result. It uses the Victorian aggregate formula and the shape of VTAC's published 2024 aggregate-to-ATAR table, but your official ATAR depends on your state's exact rules and that year's scaling, which changes annually. Always verify with VTAC, UAC, QTAC or your state's admissions centre.
