IB Score Calculator
Add up your IB Diploma score out of 45 from six subject grades plus TOK and Extended Essay bonus points, and check the 24-point pass threshold.
Frequently Asked Questions about the IB Score Calculator
How is the total IB Diploma score calculated?
You add the grades from your six subjects, each scored 1 to 7, for a maximum of 42 points. Then you add up to 3 bonus points from the Theory of Knowledge and Extended Essay matrix. The two parts together give a total out of 45 points.
How do the TOK and Extended Essay bonus points work?
Theory of Knowledge and the Extended Essay are each graded with a letter from A (highest) to E (lowest). The official IBO matrix combines the two letters into 0, 1, 2, or 3 bonus points. For example, an A in one and a B in the other gives 3 points, while two C grades give 1 point.
What score do you need to pass the IB Diploma?
You need at least 24 points out of 45 to be awarded the diploma, on top of meeting the core requirements. This calculator flags whether your total reaches 24 and shows how many points you sit above or below that line.
Why might a high total still fail the diploma?
Points alone do not guarantee the diploma. A grade of E in Theory of Knowledge or the Extended Essay, a grade of 1 in any subject, more than two grades of 2, or more than three grades of 3 or below are all failing conditions. The calculator checks each of these and lists any that apply, even when your total is above 24.
Does this calculator check every diploma requirement?
No. It checks the point-based and grade-distribution conditions that depend only on the grades you enter. It does not check CAS completion or the separate higher-level and standard-level grade rules, so confirm the full requirements with your IB coordinator.
