What Is the IB Predicted Grade Calculator?
The IB predicted grade calculator estimates the total points on your International Baccalaureate Diploma before final exams. It adds your six predicted subject grades on the 1-7 scale to the bonus from Theory of Knowledge and the Extended Essay, giving an estimated Diploma score out of 45. Predicted grades are the numbers teachers submit to universities during the application cycle, so seeing the resulting Diploma total helps you understand the offer you are likely to receive. Most conditional university places are written as a single Diploma points figure, so a predicted total of 38, for example, tells you immediately whether you are inside or outside the usual range for a given course.
- • University applications: Convert the predicted grades on your school report into the single 45-point figure admissions offices quote.
- • Target setting: See which subject grade needs to move to reach a round total such as 38, 40, or 42.
- • Coordinator checks: IB coordinators can sanity-check a cohort's predicted Diploma totals before submitting them to the IBO.
- • Scholarship planning: Many scholarships name a minimum predicted Diploma total, so estimate whether you clear the bar.
A predicted grade is the teacher's professional judgment of the grade a student is most likely to achieve, not a confirmed final result. The IBO uses the same 1-7 subject scale and the same TOK/EE bonus matrix for both predicted and final scores, so the maths is identical; only the inputs differ.
This tool reports three numbers: subject points out of 42, the TOK/EE bonus out of 3, and the combined predicted Diploma total out of 45. If you only want the bonus portion, the TOK and Extended Essay points tool handles that on its own.
If you only need the bonus part of the Diploma, open the TOK and Extended Essay points calculator to see how the A-E grades convert into 0-3 points.
How the IB Predicted Grade Calculator Works
The IB predicted grade calculator performs two lookups and one addition. First it sums your six subject grades, then it reads the TOK/EE bonus from a fixed matrix, and finally it adds the two for the total.
- Subject grades: Six integers from 1 to 7, one per Diploma subject; they sum to a maximum of 42 points.
- TOK grade: A letter A to E predicting your Theory of Knowledge result.
- EE grade: A letter A to E predicting your Extended Essay result.
- Bonus matrix: A fixed grid mapping the TOK/EE pair to 0, 1, 2, or 3 bonus points.
An E in either TOK or the Extended Essay is a failing condition. When it appears, the bonus drops to 0 and the Diploma is not awarded no matter how high the subject points are, mirroring the rule the IBO applies to final results.
The single-subject part of the Diploma is the same scale the HL/SL weighted calculator uses, so your six grades feed both views of your results.
Example: a typical predicted profile
Six subjects at 6, 6, 6, 5, 5, 4 (sum 32) with TOK B and EE B.
Subject points = 32. B/B on the matrix awards 2 bonus points. Total = 32 + 2.
Predicted Diploma total = 34 points.
A 34 is a strong predicted score that clears most standard university offers.
According to IBO - Scoring the Diploma, the Diploma is awarded on a 45-point scale: 42 points from six subjects graded 1-7 plus up to 3 bonus points from TOK and the Extended Essay.
To see how those same six grades translate into a weighted percentage for university comparison, use the IB HL SL grade calculator.
Key Concepts Explained
Four ideas sit behind every predicted Diploma total, and mixing them up is the most common source of wrong estimates.
The 1-7 subject scale
Each Diploma subject is graded 1 (lowest) to 7 (highest). Six subjects therefore contribute between 6 and 42 points, and a 7 is roughly the top 5-10% of candidates in that subject.
The 45-point ceiling
The full Diploma tops out at 45: 42 from subjects plus the 3-point TOK/EE bonus. Reaching 45 means six 7s and an A in both TOK and the Extended Essay.
The TOK/EE bonus matrix
TOK and the Extended Essay are each graded A-E, and the pair is read off a fixed grid that returns 0, 1, 2, or 3 points. The bonus depends on the combination, not on averaging the two letters.
The E failing condition
An E in either TOK or the Extended Essay is a Diploma failing condition. The bonus becomes 0 and the award is withheld, so a single E can undo an otherwise excellent subject total.
Predicted grades are not the same as a grade point average, even though both summarise performance. A GPA rescales many courses onto a 4.0 or similar band, while the IB Diploma keeps six discrete 1-7 grades and adds a separate bonus; the two numbers are not interchangeable when you compare yourself to applicants from other systems.
According to the IB Diploma Programme overview, each of the six subjects is graded 1 to 7 and the Diploma total of 45 includes the 3-point bonus from TOK and the Extended Essay.
If you also study under a GPA system, the cumulative GPA calculator shows how a different scale summarises the same coursework.
How to Use This Calculator
Enter the grades your teachers have predicted for you, then read the three results and the outcome line.
- 1 Gather your predictions: Collect the six predicted grades (1-7) from your school report or coordinator.
- 2 Enter the subject grades: Type each predicted subject grade into the six subject fields; the calculator accepts 1 through 7.
- 3 Enter TOK and EE grades: Pick your predicted Theory of Knowledge and Extended Essay letter grades, A through E.
- 4 Read the breakdown: Note the subject points out of 42 and the TOK/EE bonus out of 3 before looking at the total.
- 5 Check the outcome: Confirm whether an E grade has triggered the failing condition that withholds the Diploma.
- 6 Adjust to target: Raise one subject grade and re-run to see how close you are to a round offer such as 38 or 40.
A student predicted 7, 6, 6, 6, 5, 5 with TOK A and EE B enters those values, sees 35 subject points plus a 3-point bonus for a predicted 38, and then tests what a 7 instead of a 5 in the last subject would do to the total.
To model how end-of-course marks feed the single-subject predictions, pair this with the final grade calculator.
Benefits of Using This Calculator
An estimated Diploma total turns vague subject predictions into a number you can act on during the application cycle.
- • One comparable figure: Condenses six subject predictions plus the bonus into the single 45-point score universities recognise.
- • Early target setting: Shows exactly which grade needs to move to hit a scholarship or offer threshold before exams.
- • Failing-condition awareness: Flags the E-grade rule so a strong subject total is not quietly undermined by one component.
- • Calm coordinator conversations: Gives students and parents a shared number to discuss with teachers and counsellors.
- • System comparison: Makes the IB total easy to set against GPA-based applicants when researching universities.
Because predicted grades drive conditional offers, knowing your estimated total early lets you choose universities whose typical IB requirements you already meet or are close to meeting. If you are also weighing US-style admissions, the college GPA view helps you translate between systems.
When comparing your IB total with US applicants, the college GPA calculator shows how a GPA maps onto the same admissions picture.
Factors That Affect Your Results
Two things move the predicted total more than students expect: the bonus matrix and the E failing condition. Because the same matrix applies to final results, the points you estimate here are a fair preview of the real award, but the actual number is set only after the IBO moderates your work. Treat the total as a planning figure for offers and targets, not a confirmed result.
TOK/EE bonus swing
Moving from a B/B pair (2 points) to an A/A pair (3 points) lifts the total by a full point, which can matter near scholarship cut-offs.
The E failing condition
A single E in TOK or EE sets the bonus to 0 and withholds the Diploma, overriding even a 42-point subject block.
Subject grade distribution
Each step from 5 to 6 to 7 adds one point per subject, so three subjects improving by one grade is worth three Diploma points.
Higher Level weighting
HL subjects are harder but count the same 1-7 on the Diploma; universities may weight them separately, which this total does not capture.
- • Predicted grades are teacher estimates and are not the final IB result; the actual Diploma is awarded after external moderation and exams.
- • This tool reports the Diploma total only and does not model university-specific HL requirements or alternative offers.
The TOK/EE bonus is fixed by the IBO matrix and does not change between exam sessions, so the same grade pair always returns the same points. If you want to see how an individual subject grade converts to a more familiar band, the GPA to letter grade tool offers a rough equivalence.
According to IBO - Theory of Knowledge, TOK and the Extended Essay are each graded A-E and combine through the official matrix to award up to 3 bonus points, and an E in either is a failing condition for the Diploma.
To translate an IB subject grade into a letter band for a US application, the GPA to letter grade calculator gives a rough equivalence.
Frequently Asked Questions
Q: How is an IB predicted grade turned into diploma points?
A: Each of your six predicted subject grades (1-7) is added together for up to 42 points. The Theory of Knowledge and Extended Essay predicted grades, each A-E, are read from the official bonus matrix to add 0-3 points. The predicted Diploma total is the sum, out of 45.
Q: What is the maximum IB predicted Diploma score?
A: The maximum is 45 points: 42 from six subject grades of 7 plus the full 3-point bonus from an A in both TOK and the Extended Essay. That combination is the only way to reach a perfect predicted Diploma.
Q: How do TOK and the Extended Essay add bonus points?
A: TOK and the Extended Essay are each graded A to E, and the pair is looked up in a fixed IB matrix. Strong pairs such as A/A or A/B award 3 points, mid pairs such as B/B award 2, and weak pairs such as D/D award 0. The bonus depends on the combination, not a simple average.
Q: What happens if I get an E in TOK or the Extended Essay?
A: An E in either TOK or the Extended Essay is a failing condition for the IB Diploma. The bonus becomes 0 and the Diploma is not awarded, regardless of how high your six subject grades are. This rule applies to both predicted and final results.
Q: Are predicted grades the same as final IB results?
A: No. Predicted grades are the estimates teachers submit during university applications, while final results come after external assessment and moderation. The scoring maths is identical, but the inputs are different, so your predicted total is an estimate rather than a confirmed award.
Q: How many points do universities usually expect from IB applicants?
A: Typical offers range from about 30 to 38 points depending on the course and country, with the most competitive programmes asking for 40 or more. Because requirements vary, check the specific offer for each university rather than relying on a single threshold.
