How the IB score is calculated
The International Baccalaureate Diploma Programme awards a maximum of 45 points. Six subject grades — three Higher Level (HL) and three Standard Level (SL) — each worth 1 to 7 points, contribute a combined maximum of 42 points. The remaining 3 points come from the IB Core: your Theory of Knowledge (TOK) essay and exhibition, and your Extended Essay (EE). The TOK and EE are graded A–E independently, and the combination of the two grades determines your bonus points (0, 1, 2, or 3).
The IB does not publish a single official grade boundary table — boundaries vary by subject and exam session, and are set after each exam diet by subject committees reviewing the full cohort's performance. This calculator uses your predicted or target grades to estimate your total score; actual grades may differ.
The minimum score to earn the IB Diploma is 24 points, subject to conditions: no grade lower than 2 in any subject, no grade lower than 3 in more than three subjects, and at least 12 points across HL subjects. Failing to meet TOK and EE requirements can also result in a failing diploma regardless of subject totals.
How to use this calculator
Enter your subject names in the editable fields, then use the sliders or +/− buttons to set each grade from 1 to 7. Adjust the bonus points (0–3) to match your projected TOK/EE combination. Your total IB score updates instantly. Logged-in users can save multiple score profiles — useful for modelling best-case, predicted, and worst-case scenarios — and view their saved scores on the Baccly dashboard.
Frequently asked questions
What score do I need for a top university?
Requirements vary widely by institution and programme. Most competitive universities in the UK (Oxford, Imperial, UCL) require 38–42 points for science and engineering courses; arts and humanities programmes typically start at 36–38. US universities (MIT, Harvard, Caltech) consider the IB holistically with other application components, with strong applicants typically scoring 40+.
Do all subjects count equally?
Yes — each subject is worth 1–7 points regardless of whether it is HL or SL. HL subjects require more content and deeper assessment but are scored on the same 7-point scale. However, some universities set minimum grade conditions for specific HL subjects (e.g., HL Chemistry at 6 for Medicine).
What happens if I fail TOK or the EE?
A grade E in TOK or the EE — or an E in both — automatically results in a failing diploma, regardless of your total point score. An N grade (not submitted) has the same effect. Aim for at least a D in both to avoid this condition.
Can I use this calculator for predicted grades?
Yes. Many students use it to model predicted grades submitted to universities, as well as to track the gap between their current performance and their target score.
