ATAR Calculator: Estimate Your VCE ATAR (Victoria)

This ATAR calculator estimates a Victorian ATAR from your VCE study scores. It scales each study with the VTAC 2025 scaling report, builds your aggregate the way VTAC does, and converts it with the full 2025 aggregate to ATAR table. It is for Year 11 and 12 students, parents and teachers who want to see how scaling and subject choice change the result, not just a number.

Related tools: the study score calculator estimates the study score that goes into this tool, the study time planner helps you split revision across six subjects, and the grade average calculator tracks SAC results.

What this ATAR calculator does

The calculator has three modes, and each field has an “i” icon that explains what to enter.

• From study scores. Enter up to six VCAA study scores. The tool scales each one, picks your English score and best studies, adds the aggregate and converts it to an ATAR. It also shows your ATAR if every study score were one point higher or lower.
• From a scaled aggregate. If you already know your aggregate, it converts it with the 2025 table.
• From a target ATAR. It shows the aggregate you needed in 2025, and the average scaled score that would require across six equal studies.

It covers Victoria only, because the VCE and VTAC process is specific to this state. Other states use their own scaling, so a Victorian tool should not be used for the HSC, QCE, WACE or SACE. I point to the right official tools in the other states section.

The figures are the 2025 ones, which are the latest VTAC has published. VTAC releases the 2026 scaling report and aggregate table on results day in December, so treat any result as an estimate until then.

What the ATAR actually is

VTAC describes the ATAR as a percentile ranking of your Year 12 achievement against the age group. An ATAR of 75.00 means your results are above 75 percent of the Year 12 age group. It is reported from 0.00 to 99.95 in steps of 0.05, and it is not a mark. VTAC also points out that there is no pass or fail ATAR, and everyone who receives one has passed the VCE.

ATARs below 30.00 are shown as “less than 30” on the statement, although you can see the exact figure through the online results service. This calculator follows that rule: if your aggregate is below the 2025 cut-off of 65.93, it shows “Less than 30”. The explanation is on VTAC’s ATAR and scaling page.

How VTAC calculates the ATAR

There are three steps: scale the study scores, add them into an aggregate, then convert the aggregate to an ATAR.

Step 1: scaling

Scaling adjusts for the fact that it is harder to reach a high study score in some studies than others. VTAC is clear that this is not because the subject is harder. It is because some studies attract a more competitive group of students, which VTAC measures by how those students perform in their other studies. If students in a study tend to do better elsewhere, its scores are scaled up, and if they do worse, its scores are scaled down. Mathematics and Languages also have additional rules.

The 2025 scaling report gives the scaled score for study scores of 20, 25, 30, 35, 40, 45 and 50, rounded to whole numbers. This table shows a few of them.

Source: VTAC 2025 Scaling Report. The numbers move every year, and the full report has every study, including languages.

Step 2: the aggregate

Your aggregate is your primary four scaled scores plus up to two increments. The primary four are one English-group study (English, EAL, Literature or English Language) and your next three highest permissible scaled scores. The increments are 10% of your fifth and sixth scaled scores. Only six studies count in total.

The calculator picks your English score for you. If you enter two English-group studies, it uses the one that scales highest, and the other competes with your non-English studies. VTAC also allows unscored VET and some other studies to count as increments, and the calculator does not model those.

Step 3: aggregate to ATAR

VTAC ranks all aggregates and converts them to ATARs, then publishes the aggregate to ATAR table on results day. The calculator uses the full 2025 table, all 1,400 rows. These are the minimum aggregates for some milestones:

The full table is in VTAC’s 2025 aggregate to ATAR table. Because the ATAR is a rank in one year’s group, the thresholds shift each year.

Worked examples

These use made-up study scores to show how the pieces fit. They are illustrations, not predictions.

Example 1: a typical mixed set

A student gets English 36, Mathematical Methods 35, Chemistry 34, Biology 38, Psychology 33 and Health and Human Development 32. After scaling, English is worth 34.2, Methods 41.0, Biology 39.0, Chemistry 38.0, Psychology 31.6 and Health 28.0. The primary four add to 34.2 + 41.0 + 39.0 + 38.0 = 152.2, and the increments add 10% of 31.6 and 28.0, which is 5.96. The aggregate is 158.16, which the 2025 table converts to an ATAR of 91.10.

If every study score were one point higher, the ATAR would be 92.70, and one point lower, 89.30. A one-point change in every study score moves the ATAR by about 1.6 points either way, which is why predicted scores are best treated as ranges.

Example 2: same study scores, different subjects

Scaling changes the value of identical scores. Suppose two students each score 35 in all six studies, but they chose different subjects.

The difference comes entirely from scaling, because each student holds the same relative position in every class. This does not mean a student should pick subjects by their scaling. A 35 in a subject you do well in will usually beat a 28 in one you struggle with, and the course you want may have prerequisites. It does show why you cannot compare study scores across subjects directly.

How much of your ATAR is English?

English is one of your primary four, so it carries the same weight as each of your other top three studies. If all six scaled scores were equal, the aggregate is the English score plus three equal scores plus two 10% increments, which makes English 1 part in 4.2, or about 24%. It matters more than that if your English scaled score is above your other studies, and less if it is lower. Since English is compulsory for the ATAR, it cannot be dropped, which is why it is worth protecting when you plan your study time.

ATAR and selection rank

Your ATAR is not always the number a course uses. VTAC explains that your selection rank is your ATAR plus any adjustments, such as equity scheme or subject adjustments. Those points are added to your aggregate, and the new aggregate is converted with the same table. The adjustments differ by institution and course, so your selection rank can be different for each course on your list, and the ATAR itself does not change.

VTAC provides a subject adjustment tool to check bonus points for a course. For a sense of what recent applicants needed, its lowest selection ranks report lists the lowest ranks that received December offers. Once you know the course you want, the HECS-HELP repayment calculator and the Australia cost of living calculator help you plan the cost, and the Australia financial calculators hub has more tools.

How accurate is this calculator?

It uses real VTAC data, but it is still an estimate. These are the reasons.

• Last year’s figures. It uses the 2025 scaling report and aggregate to ATAR table. Your results will use the 2026 versions, which will differ a little.
• Rounded scaling points. The report gives whole-number scaled scores at every fifth study score. The calculator joins those points with straight lines, so values between them are approximations. I estimate that can move your aggregate by one or two points, which is about one ATAR point near 90. This is my own estimate and not a VTAC figure.
• Combination rules. VTAC only counts permissible combinations of studies, and the calculator does not check them.
• Other increments. Unscored VET, higher education and interstate credit are not included.
• Small languages. The report gives one shared line for small language studies, and the calculator uses it.

So, are ATAR calculators accurate? A calculator built on official tables can be close, but none can know the final scaling before VTAC calculates it. Use the up and down scenarios to see your range, and rely on the official ATAR on results day.

How to find your real ATAR

Eligible Victorian students receive a secure ATAR statement through My eQuals, sent to the email address in their VTAC account. To qualify, you need to have completed Year 12 that year, qualified for an ATAR, and created a VTAC account with a course application. If you finished in an earlier year, VTAC’s ATAR reprint service issues a copy. The main VTAC ATAR page has more detail, and the ATAR and scaling guide explains the full process.

Other states

Each state or territory calculates its own ATAR from its own results, so a Victorian calculator does not apply elsewhere. For other states, use the official tools or the admission centre:

• New South Wales and the ACT: the UAC ATAR Compass.
• Western Australia: the TISC ATAR calculator.
• Queensland: QTAC.
• South Australia and the Northern Territory: SATAC.

Common mistakes

• Entering marks instead of study scores. The tool wants VCAA study scores from 0 to 50, not SAC marks. The study score calculator helps you estimate the right number.
• Treating the ATAR as a percentage. It is a rank. A 90 means above 90% of the age group, not a mark of 90%.
• Ignoring scaling. Raw study scores are not what go into the aggregate.
• Counting more than six studies. Only the best six contribute.
• Treating ATAR as the selection rank. Courses can add adjustments to your aggregate.
• Choosing subjects only for scaling. A high score in a subject you do well in usually beats a low score in a highly scaled one.

Frequently asked questions

How is an ATAR calculated?

VTAC scales each study score, adds your English score, your next three best scaled scores and 10% of your fifth and sixth into an aggregate, then ranks all aggregates and converts them to ATARs between 0.00 and 99.95.

How is the ATAR calculated in Victoria?

The Victorian process has three steps: scaling by VTAC, calculating the aggregate, and converting the aggregate with a table published on results day. Enter your study scores in the calculator above to see each step.

What aggregate do I need for a 90 ATAR?

In 2025 an ATAR of 90.00 needed an aggregate of 155.19 or more. The threshold changes each year because the ATAR is a rank within that year’s group.

Is the ATAR a percentage?

No. It is a percentile rank. An ATAR of 75.00 means you did better than 75% of the Year 12 age group, which is different from scoring 75%.

What is the highest ATAR?

99.95. VTAC reports ATARs in steps of 0.05, and 99.95 is the top of the scale.

Are ATAR calculators accurate?

They can be close when they use official data, but they remain estimates. The scaling and the aggregate to ATAR table change every year, so your official ATAR may differ.
