IB score to 4.0 planning estimate
There is no single official IB-to-GPA table used by every university. This worksheet makes only a proportional estimate and keeps the 7-point source value attached.
Calculate the GPA scale conversion
The GPA scale converter maps one reported value from its source maximum to a target maximum with the proportional formula shown below.
Local calculationBoundary: this GPA estimate preserves relative position on the scale. It doesn't reproduce an institution's course, weighting, or credential-evaluation policy.
What the estimate does
For GPA records, a 6.0 average on a 7-point scale maps proportionally to 3.43 on a 4.0 scale. That is a scale comparison, not an admissions prediction and not an official conversion of an IB diploma score.
| Reported value | Source scale | 4.0 estimate |
|---|---|---|
| 3.7 | 5.0 | 2.96 |
| 7.5 | 10.0 | 3.00 |
| 85 | 100 | 3.40 |
Why institutions may calculate something else
For GPA records, universities can evaluate individual subjects, Higher Level and Standard Level courses, predicted grades, diploma totals and local context differently. Follow the specific application instructions.
Keep IB evidence visible
For GPA records, record the subject scores, course levels and total diploma information where requested. A single converted decimal can discard information that admissions readers use.
Subject scores carry more detail
An IB average compresses Higher Level subjects, Standard Level subjects, predicted grades, and final grades into one number.
A proportional GPA estimate cannot restore those attributes after they are averaged. Keep the subject-level IB evidence available whenever an institution requests more than a planning GPA.
