ATAR Calculator Online is an independent website for Australian Year 11 and 12 students, their parents and careers advisers. It has free ATAR calculators for New South Wales, Victoria, Queensland, South Australia and the Northern Territory, Western Australia and Tasmania, with guides that explain how the ATAR and scaling work in each state.
Why this site exists
Most ATAR calculators cover one state, hide where their numbers come from, or present an estimate as if it were exact. Students then trust a number that was never certain. We wanted one place that covers every state, uses the official tables each admissions centre publishes, and says plainly when a result is an estimate.
How we work
- Official sources only. Scaling and aggregate tables come from VTAC, UAC, QTAC, SATAC, TISC and TASC publications for students who finished Year 12 in 2025.
- Shown working. Every result lists the subjects that counted, their scaled scores, the aggregate, the source and the data year.
- Honest labels. Results built on a full official table are labelled official data. Results that rely on a model are labelled estimates.
- No tracking of your marks. The calculators run in your browser. Your inputs are not sent to us.
The full detail is on the methodology page.
Who writes and checks the content
Pages are written and checked by Harvy, our editor, against the admissions centre reports listed on each page. When a source changes, the page and the calculator are updated together and the change is recorded on the data updates page. To report a mistake, email info@atarcalculatoronline.com.
