Estimate an ATAR rank from scaled subject scores and an aggregate.
The aggregate sums the best four scaled subjects plus increments from additional subjects, then that aggregate is ranked against the cohort. Because ATAR is a rank, the mapping shifts slightly each year. Subject scaling means a moderate score in a strongly scaled subject can contribute more than a high score in a weakly scaled one, which is why subject choice affects the outcome.
ATAR
Aggregate = top four scaled scores + increments; ATAR maps the aggregate to a percentile rank
This is an approximate illustration only. Official ATAR calculation uses cohort data published annually by the relevant tertiary admissions centre and cannot be reproduced exactly in advance.

This calculator takes 6 inputs: Best subject scaled score, Second subject scaled score, Third subject scaled score, Fourth subject scaled score, Fifth subject increment, Sixth subject increment. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
