How It Works: The Conversion Formula
This calculator uses a standard, widely accepted method to convert your IB scores to a 4.0 GPA scale. The calculation process involves converting your IB subject scores to a GPA value and adding bonus points from your core components.
IB Subject Grade to GPA Equivalent
| IB Grade | GPA Equivalent (4.0 Scale) |
|---|---|
| 7 | 4.0 |
| 6 | 3.9 |
| 5 | 3.3 |
| 4 | 2.7 |
| 3 | 2.0 |
| 2 | 1.0 |
| 1 | 0.0 |
Core Component Bonus Points
Your grades in TOK and EE are combined to award bonus points (up to 3 points), which are then added to your total subject score before the final GPA conversion.
Frequently Asked Questions (FAQs)
Is there a universal IB to GPA conversion scale?
No, there is no single universal conversion scale. Different universities and institutions may use slightly different conversion methods. This calculator uses a common and widely accepted scale used by many U.S. universities. It's always best to check the specific guidelines of the institutions you are applying to.
How are Higher Level (HL) and Standard Level (SL) subjects treated in GPA calculation?
Most universities use the same GPA conversion for both HL and SL subjects, as the IB grading scale (1-7) is consistent. The difficulty level is reflected in the courses themselves, not the final grade's GPA conversion. This calculator does not differentiate between HL and SL scores.
Do Theory of Knowledge (TOK) and Extended Essay (EE) bonus points affect my GPA?
Yes, your TOK and EE grades, which can contribute up to 3 bonus points to your overall IB score, are factored into the total calculation. This calculator incorporates these bonus points into its final GPA estimate.
What if a subject doesn't have a numeric grade?
IB subjects are graded on a 1-7 scale. If a subject does not have a numeric grade (e.g., "N" or "P"), it is typically not included in the GPA calculation. This calculator requires numeric scores for all subjects.
