IB to ATAR Calculator 2026

Your Result:

IB Total Score = (Subject 1 + Subject 2 + Subject 3 + Subject 4 + Subject 5 + Subject 6) + TOK/EE Bonus

Maximum: 42 + 3 = 45 points

How IBAS is Calculated:

• UAC analyzes your performance within each grade band for every subject
• For example, if Grade 6 boundaries are 60-69 marks and you scored 68, you're in the high range of that band
• An average position is calculated across all six subjects
• The result is rounded to intervals of 0.25 (e.g., 37.00, 37.25, 37.50, 37.75)
• This IBAS is then converted to a Combined Rank (ATAR equivalent)

How is IB converted to ATAR for university admission?

IB scores are converted to a Combined Rank (ATAR equivalent) using official conversion tables published by UAC and other state tertiary admission centers. For Australian IB students (November 2022 onwards), the conversion uses IBAS (IB Admissions Score) which provides more granular differentiation. Universities treat this Combined Rank the same as an ATAR for admission purposes.

Do conversion tables change each year?

Yes, IB to ATAR conversion tables are updated annually based on statistical analysis comparing IB and ATAR cohort performance. Changes are typically minor (0.1-0.3 ATAR points) but can affect competitive course cut-offs. Always use the most current official table from UAC or your state's tertiary admissions center.

Can I use my IB score to apply to all Australian universities?

Yes, all Australian universities accept the IB Diploma as equivalent to Year 12 qualifications. You apply through state-based portals (UAC for NSW/ACT, VTAC for Victoria, QTAC for Queensland, TISC for WA). Some courses may have additional IB-specific prerequisites, such as requiring Higher Level subjects.
