Free ATAR calculators
No signup. No ads. No data leaves your browser. ATAR estimators for every Australian state, built by ExamExplained from each admissions centre's published 2025 data.
ATAR calculators
Estimate your ATAR from your HSC marks using UAC's 2025 scaling report: per-course scaled-mark percentiles, the best 2 units of English plus best 8 other units, and UAC's aggregate-to-ATAR points.
Estimate your ATAR from your VCE study scores using VTAC's 2025 scaling report and aggregate-to-ATAR table: English plus your next best three, plus 10% of a fifth and sixth study.
Estimate your ATAR from your QCE results using QTAC's 2025 subject scaling: best 5 General subjects, or 4 General plus 1 Applied subject or VET qualification.
Turn your Stage 2 scaled scores into a SATAC university aggregate (best three 20-credit subjects plus a 30-credit flexible option, out of 90) and an estimated ATAR from SATAC's 2025 table.
Turn your ATAR course scaled scores into a TISC TEA (best four plus the LOTE and maths bonuses, out of 430) and an estimated ATAR from TISC's 2025 conversion.
Turn your TASC awards or course scores into a Tertiary Entrance Score (best five Level 3 and 4 courses) and an estimated ATAR from TASC's 2025 scaling and conversion tables.
Life after school
How much of your graduate paycheck goes to HECS. Models the ATO's marginal repayment system for 2026-27 and 2025-26, plus the old 2024-25 schedule.
How a savings balance grows over time, or how much you need to put aside each month to hit a goal like a car, Schoolies, or a first-home deposit.
Apply the 50/30/20 framework to a graduate take-home weekly wage. Picks up the weekly unit rent for your city to flag when rent is eating the whole needs envelope.
Convert AUD to 20 travel currencies at mid-market rates, then see what each provider (fintech, travel card, credit card, ATM, DCC) keeps as a fee.
Transfer duty for each state, the headline first-home buyer concession, and 5, 10 and 20 percent deposit scenarios with indicative Lenders Mortgage Insurance.
Subject calculators
Projectile motion, centripetal force, banking angle, gravitation, escape velocity, Kepler's third law, and orbital energy. Built for Module 5 Advanced Mechanics.
pH and pOH, weak-acid pH, buffer pH, equilibrium constant, K_sp, dilution, titration, mole conversion, Beer-Lambert, calorimetry.
Monohybrid and dihybrid Punnett squares, sex-linked inheritance probabilities, and the Hardy-Weinberg equilibrium calculator.
How accurate are these?
These are estimators, not official tools. Each one uses its own state's published 2025 data: UAC's and VTAC's scaling reports and aggregate-to-ATAR tables, QTAC's subject scaling, SATAC's and TASC's conversion tables and TISC's ATAR calculator. Scaling and the conversion to an ATAR change every year, so treat results as a guide.
For your official ATAR, look at the relevant tertiary admissions centre: UAC (NSW), VTAC (VIC), QTAC (QLD), SATAC (SA and NT), TISC (WA) or TASC and the University of Tasmania (TAS). Our calculators help you plan subject choices and target marks, not replace the official calculation.
