SACE AGGREGATE CALCULATOR
Add the best 90 credits before interpreting the ATAR.
Use scaled scores out of 20 and 10. The calculator totals the required 60-credit TAS block and 30-credit flexible option, then looks up the matching value in SATAC's complete 2025 historical table.

The aggregate-to-ATAR relationship changes every year. SATAC will publish the 2026 table in December 2026.The aggregate arithmetic follows the published 60 + 30 credit structure. Eligibility, precluded combinations, counting restrictions and official scaling still require SATAC verification. The ATAR shown is an exact lookup from the official 2025 table, not a 2026 prediction.
DIRECT ANSWER
How is the SACE ATAR calculated?
SATAC first calculates a university aggregate from the best eligible 90 credits: three 20-credit Tertiary Admissions Subjects or valid pairs for the first 60 credits, plus the best approved 30-credit flexible option. SATAC then compares that aggregate with the same-year cohort to assign an ATAR. Because the final relationship changes every year, this page keeps the aggregate calculation separate from its clearly labelled 2025 historical lookup.
BUILT AROUND SATAC'S REAL INPUTS
A SACE ATAR calculator with aggregate, scaling context and targets
The workbench covers the high-intent SACE aggregate, scaling, four-subject, VET and predicted ATAR questions without inventing a grade conversion.
30-credit flexible option
Add an eligible 20-credit score plus a 10-credit TAS or half of another 20-credit TAS. Approved Recognised Studies can contribute within SATAC limits.
Official 2025 lookup
Every 0.05 aggregate step from the complete SATAC 2025 conversion table is stored locally for an exact historical reference.
Target aggregate planner
Choose a target ATAR and see the minimum university aggregate that reached it in 2025, plus the current aggregate gap.
FROM SACE RESULTS TO ATAR
The SACE aggregate calculation in four stages
Eligibility and arithmetic are related but not identical. The calculator can add eligible scores, while SATAC remains responsible for subjects, scaling and the official rank.
Confirm ATAR eligibility
Complete the SACE or NTCET, at least 90 eligible Stage 2 credits and the required TAS pattern. Precluded combinations and counting restrictions still apply.
Use scaled scores, not letter grades
A SACE grade covers a range of raw and scaled outcomes. SATAC states there is no direct conversion from one overall grade to one scaled score.
Build the university aggregate
The first 60 credits come from three 20-credit TAS or valid pairs. The flexible option supplies the best approved 30 credits, with no more than 20 Recognised Studies credits.
Convert within the same year
SATAC ranks each year's aggregate distribution against the age population. The 2025 table is useful for historical comparison but cannot reproduce the unpublished 2026 cohort.
2026 ACCURACY NOTICE
The 2026 SACE ATAR conversion table does not exist yet
SATAC says the 2026 SACE/NTCET university aggregate to ATAR table will be published in December 2026 and warns that historical tables are not reliable future predictors. The aggregate shown here is exact for the scores entered; the accompanying ATAR is an exact 2025 reference only. Subject scaling, eligibility and the official 2026 ATAR remain SATAC decisions.

COMMON QUESTIONS
SACE ATAR calculator FAQs
Answers to common questions about 90 credits, scaled scores, the flexible option, VET, four subjects, adjusted ranks and 2026 accuracy.
How is the SACE ATAR calculated?
SATAC totals the best eligible 90 credits into a university aggregate out of 90, then ranks that aggregate against the same-year cohort and age population. The aggregate uses scaled scores, not a simple average of letter grades.
How many SACE credits do you need for an ATAR?
You need at least 90 eligible Stage 2 credits for the university aggregate. At least 60 credits must come from three 20-credit TAS or valid subject pairs; the remaining 30 credits form the flexible option.
How many subjects go towards a SACE ATAR?
The rule is based on 90 credits rather than one fixed subject count. A common pattern is four 20-credit subjects plus a 10-credit subject, but valid pairs, half of a 20-credit TAS and approved Recognised Studies can change the mix.
Can four SACE subjects calculate an ATAR?
Four 20-credit subjects supply 80 credits, so another eligible 10-credit contribution is normally needed to reach 90. The flexible option can use a 10-credit TAS or half of an additional 20-credit TAS where the rules allow it.
Does SACE subject scaling affect the ATAR?
Yes. SATAC converts raw subject outcomes into comparable scaled scores before forming the aggregate. Scaling reflects the cohort and there is no fixed A, B or C grade-to-scaled-score conversion.
Should I enter raw marks or scaled scores in this SACE ATAR calculator?
Enter SATAC scaled scores out of 20 or 10. Raw percentages and overall grades cannot reproduce the official scaling process and would give a misleading aggregate.
Can VET count towards a SACE ATAR?
Approved Certificate III or higher VET may count as Recognised Studies in the flexible option. SATAC allows a maximum of 20 Recognised Studies credits and calculates the VET scaled contribution from eligible TAS results.
What is the SACE flexible option?
It is the final 30 credits of the university aggregate. SATAC can use the best approved combination of a 20-credit TAS, 10-credit TAS, half of a 20-credit TAS and eligible Recognised Studies, subject to restrictions.
Is this SACE ATAR calculator accurate for 2026?
It accurately adds the entered scores under the displayed 60 + 30 structure. The ATAR beside it is the exact 2025 table value, not a 2026 prediction; SATAC will not publish the 2026 conversion table until December 2026.
Is an adjusted ATAR the same as the SACE ATAR?
No. The official ATAR is based on the university aggregate. Eligible adjustment factors may raise the selection rank used for a particular course, but they do not change the ATAR issued to the student.
