ATAR Calculator
Estimate your ATAR from expected HSC marks using 2019–2025 UAC scaling data.
For the most accurate ATAR estimate, use the official UAC ATAR Compass. This calculator uses historical data and is a best-effort estimate. Results may differ.
How to use this calculator
- Select your subjects: Choose your 10 or more units of study from the dropdowns below.
- Enter your marks: Enter your estimated HSC marks (out of 100). For 1-unit extension courses, double your NESA mark (e.g. 45/50 → 90/100).
- Analyse the result: The scaled marks and ATAR estimate based on past scaling data (2019–2025) are shown below.
