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.
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.

Complete IB to GPA Conversion Chart
Use this estimated IB-to-GPA chart as a quick reference for March 31, 2026. It shows a common 4.0-scale conversion by subject grade. Policies vary by university, so treat this as a planning guide and confirm official conversion rules with the institution you are applying to.
| IB Grade | Estimated 4.0 GPA | Typical Interpretation | Admission Context |
|---|---|---|---|
| 7 | 4.0 | Excellent mastery | Highly competitive result in both HL and SL subjects. |
| 6 | 3.7 | Very strong performance | Strong admission-grade result across most universities. |
| 5 | 3.3 | Good performance | Usually acceptable, though selective programs may expect more HL strength. |
| 4 | 3.0 | Satisfactory pass | Passing result, but often below the profile of more competitive offers. |
| 3 | 2.0 | Limited performance | Usually weak for selective admissions and may need stronger support elsewhere. |
| 2 | 1.0 | Below passing standard in many contexts | Often treated as a serious weakness or non-competitive result. |
| 1 | 0.0 | Failing performance | Normally not acceptable for diploma or admission planning purposes. |
Important: This chart reflects a commonly used estimate, not an official IB conversion rule. Some schools use different values for 6, 5, and 4, and some high schools apply extra weighting to HL courses when reporting cumulative GPA.
IB Grades to GPA: Frequently Asked Questions
Calculating a Grade Point Average (GPA) from your International Baccalaureate (IB) grades generally involves converting each IB subject grade, which ranges from 1 to 7, into an equivalent point on the desired GPA scale, commonly the 4.0 scale in the US. After converting each subject, you then average these points.
The basic steps are:
- List all your IB subjects that received a final grade from 1 to 7.
- Use a specific conversion table to find the GPA equivalent for each IB grade, for example IB 7 = 4.0 GPA and IB 6 = 3.7 GPA.
- Sum up all the GPA equivalents.
- Divide this sum by the total number of IB subjects included in the calculation, usually 6.
Important: Different universities and institutions may use slightly different conversion scales. Always check their specific guidelines if you are applying.
No, there is not one single, universally accepted conversion scale. While the IB Organization provides the 1 to 7 grading system for its subjects, it does not prescribe a specific GPA conversion.
Universities and educational systems that use GPA, primarily in the US and Canada, develop their own internal policies for converting IB grades. This means the GPA value for an IB 7 or an IB 6 can vary from one institution to another.
A common example of a conversion scale used by some institutions is:
- IB Grade 7 = 4.0 GPA
- IB Grade 6 = 3.7 GPA, sometimes 3.6 or 3.8
- IB Grade 5 = 3.3 GPA, sometimes 3.0 or 3.4
- IB Grade 4 = 3.0 GPA, sometimes 2.0, 2.3, or 2.7
- IB Grade 3 = 2.0 GPA, sometimes 1.0 or 1.3
- IB Grade 2 = 1.0 GPA, sometimes considered failing
- IB Grade 1 = 0.0 GPA, considered failing
Always refer to the specific university's admissions website or contact their admissions office for the official IB grade conversion policy.
For the direct conversion of IB subject grades from 1 to 7 to a GPA scale, most institutions apply the same conversion logic to both HL and SL subjects. An IB grade of 6 in an HL subject would typically convert to the same GPA point as an IB grade of 6 in an SL subject according to that institution's scale.
However, universities are well aware of the increased rigor and depth of HL courses. This recognition often comes in other ways:
- Admission Selectivity: Universities highly value strong performance in HL subjects, especially those relevant to the intended field of study.
- Course Credit or Placement: Good HL scores, often 5, 6, or 7, may grant students university course credits or advanced placement, allowing them to skip introductory courses.
- Weighted GPA by High Schools: Some high schools, when calculating a cumulative GPA for their students, might apply an additional weight to IB HL courses, for example by adding 0.5 or 1.0 to the converted GPA for HL subjects. This is a high school practice, not typically how universities initially convert IB subject grades themselves for admissions review.
So, while the direct grade-to-point conversion is often uniform, the distinction and value of HL courses are recognized in the broader admissions and academic placement context.
Generally, no, the bonus points awarded for TOK and EE do not directly factor into the calculation of your subject-based GPA.
Here is why:
- GPA is typically calculated from individual academic subject grades.
- TOK and EE are core components that contribute, along with CAS, to the overall IB Diploma. Their performance is combined to award up to 3 bonus points toward your total IB Diploma score out of 45.
While not part of the GPA, the total IB Diploma score, which includes these bonus points, is highly significant. Universities look at this total score as a key indicator of your overall achievement in the rigorous IB program. Strong performance in TOK and EE, reflected in your grades A to E and the resulting bonus points, enhances your academic profile and demonstrates critical thinking and research skills valued by universities.
Certainly. Let us use a common, but hypothetical, conversion scale where:
- IB 7 = 4.0
- IB 6 = 3.7
- IB 5 = 3.3
- IB 4 = 3.0
- IB 3 = 2.0
- IB 2 = 1.0
- IB 1 = 0.0
Step 1: List your IB subjects and grades.
Suppose a student has the following 6 IB subject grades:
- English A HL: 6
- Spanish B SL: 7
- History HL: 5
- Biology HL: 6
- Mathematics SL: 5
- Visual Arts SL: 4
Step 2: Convert each IB grade to its GPA equivalent using the chosen scale.
- English A HL (6) = 3.7 GPA
- Spanish B SL (7) = 4.0 GPA
- History HL (5) = 3.3 GPA
- Biology HL (6) = 3.7 GPA
- Mathematics SL (5) = 3.3 GPA
- Visual Arts SL (4) = 3.0 GPA
Step 3: Sum up all the GPA equivalents.
3.7 + 4.0 + 3.3 + 3.7 + 3.3 + 3.0 = 21.0
Step 4: Divide the sum by the number of subjects, 6 in this case.
21.0 / 6 = 3.50
So, using this specific conversion scale, the student's estimated IB GPA would be 3.50.
This is an unweighted GPA based purely on the subject grade conversions. Your high school might report a weighted GPA if it adds extra points for HL courses.
If an IB subject has a non-numeric grade indicator like N for No Grade awarded or P for Pending, it is typically not included in the GPA calculation.
GPA calculations rely on numeric subject grades from 1 to 7 that can be converted to a point value.
- An N grade means no mark was submitted or the work was not assessable, so it effectively carries no value for GPA purposes.
- A P grade indicates that the result is still pending and will be released later. Once the final numeric grade from 1 to 7 is available, it can then be included.
If you have such a grade for one of your six subjects and are trying to estimate your GPA, you would typically calculate the GPA based on the remaining subjects that do have numeric grades, or wait until the pending grade resolves.
This depends on context:
Unweighted Conversion: When you directly convert each IB subject grade from 1 to 7 to a point on a 4.0 scale, for example IB 7 = 4.0 and IB 6 = 3.7, and then average these points, the resulting GPA is generally considered an unweighted GPA for those IB courses. This method treats an IB 6 in an SL subject the same as an IB 6 in an HL subject in terms of direct point conversion.
Implicit Weighting and University Recognition: Universities inherently understand the advanced nature of the IB Diploma Programme. All IB courses, especially HL subjects, are recognized as rigorous, college-level coursework. So, even if they use an unweighted conversion for the initial calculation, their overall assessment of your IB transcript still gives weight to the program's difficulty.
High School Weighted GPA: Some high schools, when calculating a student's overall cumulative GPA that includes IB courses alongside regular or honors courses, may apply an explicit weight. For example, they might add an extra 0.5 or 1.0 quality point to the converted GPA for IB HL, and sometimes SL, courses. This would result in a weighted GPA on your high school transcript.
In summary:
- The direct subject-by-subject conversion is usually unweighted.
- Universities recognize IB rigor regardless of explicit weighting in the conversion.
- Your high school might report a weighted GPA that includes IB courses.
It is always best to clarify with any institution how it interprets and uses IB grades in GPA calculations or admissions reviews.
