ATAR calculator for every Australian state.

ATAR calculator Australia: a clear estimate for every state

This free ATAR calculator helps Year 12 students in every Australian state and territory turn their subject marks into a realistic ATAR estimate. It applies the counting rules published by each admissions centre and the course scaling distributions from UAC’s 2025 report. There is no sign-up, no cost, and no marks are stored on our servers.

The ATAR is a rank, not a percentage. An ATAR of 80.00 means you performed as well as, or better than, 80 per cent of your age group — not that you scored 80 per cent. Because the scale is national, an estimate of 80.00 in New South Wales means the same as 80.00 in Victoria, Queensland or any other state.

ATAR calculator HSC and UAC (NSW)

If you are completing the HSC in New South Wales, the ATAR calculator uses UAC’s 10-unit rule: your best two units of English, even when English is your weakest subject, plus your best eight units from your remaining courses. Each HSC mark is placed inside its course’s 2025 distribution and converted to a scaled mark before the aggregate is mapped to an ATAR. The dedicated ATAR calculator NSW page explains eligibility and the full UAC rule.

ATAR calculator VIC (VCE and VTAC)

In Victoria, the ATAR calculator estimates your VTAC aggregate from VCE study scores. English must be one of your four primary studies, and 10 per cent of your fifth and sixth permissible study scores are added as increments. Study scores are standardised around a mean of 30, so each score is converted to a percentile before it is matched to a scaled distribution. The ATAR calculator VIC page covers English options and study-score rules.

ATAR calculator QLD (QCE and QTAC)

Queensland students receive an ATAR calculated by QTAC from the best five eligible subject results. You can count five General subjects, or four General subjects plus an Applied subject or a completed Certificate III. The ATAR calculator QLD page explains which subject combinations are accepted and how QTAC’s 2,000 ATAR bands work.

ATAR calculator SACE and NTCET (SA and NT)

South Australian and Northern Territory students are ranked by SATAC using the best 90 credits of study, including at least 60 credits from 20-credit Tertiary Admissions Subjects and 20 credits of English. The calculator applies the 90-credit structure, including the half-weight flexible option. For SACE students, the ATAR calculator SA page sets out the credit rules, while NTCET students can use the ATAR calculator NT page for the equivalent Northern Territory requirements.

ATAR calculator WACE (WA and TISC)

Western Australia’s ATAR is built from four scaled subjects and must include English or Literature. TheWACE ATAR calculator WA page covers the TISC rules and the prerequisite subjects that some university courses require. It also explains why a high ATAR does not override a missing prerequisite, and how school marks are scaled across WACE courses.

ATAR calculator Tasmania (TASC)

The Tasmanian ATAR uses the best five scaled results and includes English or a recognised alternative. Visit the ATAR calculator Tasmania page for TASC eligibility details and the subject patterns that can count. Tasmanian results are reported on the same national scale as every other state, so you can compare them directly.

ATAR calculator ACT (BSSS)

ACT ATARs are calculated by the Board of Senior Secondary Studies with UAC using the same 10-unit structure as NSW. The ATAR calculator ACT page explains tertiary package requirements and how the ACT rank compares with the rest of Australia.

How to use this ATAR calculator

Choose your state, enter the marks you have received or expect, and add every subject that could count. The calculator automatically applies your state’s rules, shows the scaled mark behind each subject, and displays a likely ATAR range. Update your marks as assessments come in, and include extension or VET subjects where they apply. Use the range rather than a single number when you compare course prerequisites or plan your university preferences.

Why your scaled mark can be lower than your school mark

Scaling does not punish you. It compares your performance with the students who took the same course. A subject taken by a very strong cohort can produce lower scaled marks because a high raw mark is harder to achieve in that group. The opposite is also true: a strong result in a less competitive course can scale well. What matters is your rank within the course, not the raw number on its own.

What the estimate does not include

The calculator does not apply adjustment factors, subject bonuses, equity schemes or course prerequisites. It also leaves out vocational qualifications, interstate study, IB conversions and accumulated study from earlier years. Those factors can change your selection rank, but they do not change the ATAR itself. Always confirm the official rules with the admissions centre in your state before making final course decisions.

Which ATAR calculator is most accurate?

New South Wales has the highest confidence because the model is built directly on UAC’s published 2025 scaling report and aggregate-to-ATAR table. Victoria, Queensland, South Australia, Western Australia, Tasmania, the ACT and the Northern Territory use their own counting rules with UAC’s course distributions as reference data, so those results are labelled indicative and shown with a wider range. Every result here is an estimate, not an official rank.
