Your IB Performance Summary

Total Subject Score: N/A

TOK/EE Bonus Points: N/A

Total IB Diploma Score: N/A / 45

Estimated GPA (US 4.0 Scale): N/A

Note: GPA conversion is an estimate. Universities use varied scales. This calculator uses a common conversion based on subject grades (7=4.0, 6=3.9, 5=3.3, 4=2.7, 3=2.0, 2=1.0, 1=0.0). Bonus points contribute to the total IB score, not directly to this GPA calculation method.

How This IB to GPA Calculator Works in 2026

This calculator is designed for IB students, teachers and parents who want a quick, practical estimate on a US 4.0 GPA scale before checking a university's exact policy.

The conversion used here is a common subject-by-subject model: 7 = 4.0, 6 = 3.9, 5 = 3.3, 4 = 2.7, 3 = 2.0, 2 = 1.0, and 1 = 0.0. That means this ib score to gpa converter and ib points to gpa converter works best when your six subject grades are complete.

Important: there is no single official universal IB to GPA conversion. Universities in the US, Canada, the UK, and elsewhere may use different internal policies, especially when they evaluate HL rigor, weighted transcripts, or bonus points.

Common IB Points to GPA Examples

36 IB points to GPA

A common example is 6, 6, 6, 6, 6, 6. That equals 36 subject points and an estimated 3.90 GPA on this calculator. If your 36 includes TOK or EE bonus points, the GPA can be lower than 3.90.

37 IB score to GPA

A common example is 7, 6, 6, 6, 6, 6. That equals 37 subject points and an estimated 3.92 GPA. This is why a 37 ib score to gpa search usually needs subject-level detail, not only the final diploma total.

42 IB points to GPA

If your 42 IB points come from six 7s across all six subjects, the estimate is 4.00 GPA. But if your 42/45 includes TOK or EE bonus points rather than all-subject 7s, the GPA estimate may sit below a perfect 4.0.

IB GPA Questions Students Ask Most

Is there an official universal IB to GPA conversion?

No. The IB does not publish one mandatory universal GPA conversion. That is why terms like ib conversion to gpa, ib score conversion to gpa, and ib to gpa converter online often lead students to estimate tools first and then to university-specific policy pages second.

Do HL and SL subjects convert differently?

In this calculator, the grade conversion is driven by the subject score itself, not by a separate HL or SL multiplier. Many universities still value HL rigor during admissions review, even when the direct ib program gpa scale conversion looks unweighted.

Do TOK and EE bonus points change GPA?

Not directly. TOK and EE bonus points change the total diploma score out of 45, but the estimated GPA here is based on the converted subject grades. That is why 42 ib points to gpa can mean different things depending on whether the 42 came from subject grades alone or from subject grades plus bonus points.

What about weighted GPA for IB?

Some high schools create their own weighted GPA for IB HL classes, but colleges often read the official IB transcript separately. Use this page as an estimated unweighted conversion first, then check whether your school or target university applies extra weight to IB coursework.
