About the IB Diploma Score Calculator
This IB score calculator adds up a Diploma Programme result the way the International Baccalaureate does: six subject grades from 1 to 7 (up to 42 points) plus up to 3 core points from the theory of knowledge (TOK) and extended essay (EE) matrix, for a maximum of 45. Enter predicted or final grades, mark each subject as higher level (HL) or standard level (SL), and pick your TOK and EE letter grades.
A total of 24 is not enough on its own. The calculator also checks the published failing conditions — no grade 1, no more than two grade 2s, no more than three grades of 3 or below, at least 12 HL points and 9 SL points (5 SL points if you take four HL subjects), no E in TOK or EE, no N grades and completed CAS — and lists exactly which rule you would miss.
The rules follow the diploma requirement codes and TOK/EE matrix in the IB’s Diploma Programme Assessment procedures (unchanged for the 2025 and 2026 sessions). Students use it to see which predicted grades a university offer of 32 or 38 points really requires; teachers and coordinators use it to sanity-check predictions. The bilingual diploma and the rare academic-misconduct penalty are not modelled, and the IB itself issues the official result.
With the default inputs, the ib diploma total is 35 / 45. Change any value above to recalculate instantly.
How to use the ib diploma score calculator
- 1Enter your predicted or final grade (1–7) for each of the six subjects.
- 2Mark each subject as higher level (HL) or standard level (SL).
- 3Pick your theory of knowledge and extended essay letter grades.
- 4Confirm whether your CAS requirements are complete.
- 5Read your total out of 45 and the list of any pass conditions you would miss.
Formula and method
Each of the six subjects earns a grade from 1 to 7, and HL and SL subjects carry the same points, so subjects contribute up to 42. TOK and the extended essay are graded A–E and combined through the IB matrix: A/A, A/B and B/A give 3 points; A/C, A/D, B/B, B/C, C/A, C/B and D/A give 2; B/D, C/C and D/B give 1; C/D, D/C and D/D give 0. An E in either component, or an N in anything, is a failing condition rather than a score.
The diploma requires at least 24 points and none of the failing conditions: no grade 1, fewer than three grade 2s, fewer than four grades of 3 or below, at least 12 points on HL subjects (best three when four are taken), at least 9 points on SL subjects (5 points when only two SL subjects are taken) and completed CAS. The calculator checks each condition and lists the ones that fail.
- Subject grade
- IB grade 1–7 for each of the six subjects
- Core points
- Points from the TOK and EE grade matrix (0–3)
- HL points
- Sum of the best three higher level grades
- SL points
- Sum of the standard level grades
Worked examples
Typical 35-point diploma
HL grades 6, 6 and 5 give 17 points and SL grades 6, 5 and 5 give 16, so subjects total 33. TOK B with EE B is worth 2 core points on the matrix, giving 35 out of 45 with every condition met.
Top student aiming for 42
Subjects add to 7 + 7 + 6 + 7 + 6 + 6 = 39. An A in both TOK and EE earns the maximum 3 core points, so the total is 42 out of 45.
31 points but a grade 1
The points add to 29 + 2 = 31, comfortably above 24, and HL (14) and SL (15) both clear their minimums. But a grade 1 in any subject is a failing condition on its own, so the diploma would not be awarded.
E on the extended essay
An E in the extended essay earns no core points, leaving 33 subject points. More importantly, an E in TOK or EE is a failing condition, so the diploma is not awarded despite the 33 points.
Frequently asked questions
What is the maximum IB score?+
The maximum is 45 points: six subjects graded 1 to 7 give up to 42 points, and the theory of knowledge and extended essay together add up to 3 core points through the IB matrix.
What is the minimum score to pass the IB Diploma?+
You need at least 24 points, and you must also avoid every failing condition — for example a grade 1, three or more grade 2s, fewer than 12 HL points, an E in TOK or EE, or incomplete CAS.
How do TOK and EE points work?+
TOK and the extended essay are each graded A to E. The IB combines the two grades in a matrix: two A grades or an A with a B give 3 points, while two D grades give 0. An E in either one means the diploma cannot be awarded.
Do HL subjects count for more points than SL?+
No. A 7 at higher level and a 7 at standard level are both worth 7 points. HL matters for the separate rule that your best three HL grades must add up to at least 12 points.
Can I fail the IB with more than 24 points?+
Yes. A student can score 30 or more and still miss the diploma because of a failing condition such as a grade 1, an E on the extended essay or incomplete CAS. You still receive DP course results for each subject.
What is a good IB score?+
Selective universities often ask for 34–40 points, sometimes with specific HL grades such as 6, 6, 6. Check each course’s offer because requirements vary widely by university and subject.
