Score the 45-Point IB Diploma

The IB HL SL Grade Calculator totals your six International Baccalaureate subject grades and your Theory of Knowledge and Extended Essay results into the official 45-point IB Diploma score. Each subject is marked 1 to 7, and Higher Level and Standard Level subjects count the same way, so this tool is the quickest way to see where your Diploma stands before results day.

• • Predicted grades: Enter teacher-predicted grades to estimate your Diploma total for university applications.
• • Mock results: Add your mock exam grades to check which bands you need to improve.
• • Scholarship thresholds: See whether a 45-point total clears a specific offer or scholarship line.
• • TOK/EE planning: Test how different TOK and EE letter grades shift your bonus points.

The Diploma is built from two parts: up to 42 points from your six subjects and up to 3 core points from TOK and the Extended Essay. This calculator adds both parts and then checks the award conditions so you know whether the total would earn the Diploma.

You do not need to separate HL from SL when adding points, because both levels use the identical 1-7 scale. The distinction matters only for the band minimums, which the calculator applies automatically.

Most candidates take three subjects at Higher Level and three at Standard Level, which is the structure the form assumes. If your school runs a different mix, the subject total is still just the sum of six 1-7 grades, so the tool still reflects your position even though the HL/SL band checks may not match your exact enrolment.

If you also need to combine term marks from a single course, our final grade calculator works out the running average before you map it onto the IB scale.

The IB HL SL Grade Calculator follows the IB scoring method exactly: it sums the six subject grades, looks up the TOK and EE bonus from the official matrix, adds them, and evaluates the pass conditions.

• Subject grades: Six integer grades from 1 to 7, three Higher Level and three Standard Level.
• TOK grade: Letter result A to E for Theory of Knowledge.
• EE grade: Letter result A to E for the Extended Essay.
• Core points: 0 to 3 points read from the TOK/EE matrix; an F withholds the award.

The TOK/EE matrix crosses your two letter grades. TOK A with EE A earns 3 points, TOK B with EE B earns 2, and several weak combinations return F, which means the Diploma is not awarded no matter how strong your subjects are.

Because the matrix is fixed, the calculator needs only your two letter grades to return the exact core contribution.

The core points rarely decide the Diploma on their own, but they sit on the boundary of many offers. A candidate at 23 subject points with a B/B core reaches 25 and passes; the same candidate with a C/C core stays at 24, which still passes, but a D/D core drops to 23 and fails the total entirely. Small core shifts therefore flip outcomes that look identical at the subject level.

According to IBO - Scoring the Diploma, The Diploma is awarded on a maximum of 45 points: up to 42 from six subjects graded 1-7 plus up to 3 bonus points for Theory of Knowledge and the Extended Essay.

Unlike a simple weighted grade calculator that counts every course equally, the IB totals each subject the same regardless of HL or SL.

Four ideas explain why the IB total behaves the way it does and where students most often lose points.

Understanding the band minimums is as important as the total. The IB HL SL Grade Calculator applies them automatically, so a candidate can clear 24 points overall yet still miss the Diploma if the HL or SL bands fall short.

The core points are small in number but can be decisive near a scholarship or offer boundary. Universities that publish a points threshold usually mean the final 45-point figure, so a 2-point core swing can be the difference between meeting and missing a conditional offer.

Grade boundaries within each subject are set by the IB after exams, not by the calculator, so the 1-7 inputs you provide are your own reading of your results. Treat the output as a faithful combination of whatever grades you enter rather than a prediction of the boundaries themselves.

When comparing your result with other systems, the GPA to percentage converter helps translate a different grading scale into percentages.

Enter your grades in the order shown, then read the total and the award result beneath the form.

1. 1 Enter your three HL grades: Type your Higher Level subject grades, each between 1 and 7.
2. 2 Enter your three SL grades: Type your Standard Level subject grades, each between 1 and 7.
3. 3 Select TOK and EE letters: Pick your Theory of Knowledge and Extended Essay results from A to E.
4. 4 Read the Diploma total: The result panel shows your total out of 45, core points out of 3, and subject total out of 42.
5. 5 Check the award result: The calculator states whether the combination would meet the IB award conditions.

A student with HL 7, 6, 6 and SL 6, 5, 5 plus TOK B and EE A enters those values and sees a 39-point total with the award met, then tests dropping TOK to D to watch the core points fall from 2 to 1.

If you are submitting both qualifications to universities, our SAT score percentile calculator shows how standardised test results sit against the cohort.

Beyond a single number, the tool helps you plan and interpret your Diploma result.

• • Catch failing conditions early: The calculator flags an HL or SL band shortfall that a raw total would hide.
• • Test TOK/EE scenarios: You can see exactly how a one-letter change in TOK or EE moves your bonus points.
• • Plan university applications: An estimated total helps you judge whether predicted grades clear an offer.
• • Avoid F surprises: The tool shows when a TOK/EE F withholds the award despite strong subjects.
• • Verify mock outcomes: Comparing mock grades against the band rules shows which subjects matter most.

Because the band conditions interact, a single low grade can change the verdict. The IB HL SL Grade Calculator makes that interaction visible instead of leaving it to manual checking.

Students often overestimate how much a strong subject offsets a weak one; the tool keeps the rules literal. A grade 7 in one HL subject does not cancel a grade 1 elsewhere, and two grade 2s at HL are themselves a failing condition regardless of the total.

Revisiting the same profile with better TOK or EE grades also shows how much of your outcome rests on the core. For a student hovering near 24 points, lifting the EE from C to B can add the point that turns a fail into a pass, which is useful information when you are deciding where to spend revision time.

You can then feed a comparable average into the percentage to GPA calculator when a college asks for a GPA instead of points.

Several IB rules shape the final award, and a few limits apply to this estimate.

• • This calculator estimates the Diploma total from grades you enter; it does not replace the official IB results issued by the IB organisation.
• • The subject-group compensating pair rule for a grade 1 is not encoded here because it depends on which subject groups you take; always confirm edge cases with your coordinator.

CAS is another requirement: it carries no points but must be completed, so a strong points total still needs CAS to be awarded the Diploma.

The compensating pair rule is the one edge case this tool cannot resolve on its own. A single grade 1 is normally a fail, but the IB allows a grade 1 to be balanced by a grade 2 at a higher level within the same subject group, subject to other limits. Because the calculator does not ask which subject group each grade belongs to, it reports the strict rule and leaves the pairing decision to your coordinator.

Treat the output as a planning estimate and confirm boundary cases with your school's IB coordinator.

As published by IBO - Assessment and Exams, Candidates must satisfy total, Higher Level, Standard Level, and core conditions, and a grade 1 in any subject is a failing condition.

Admissions teams may also weigh English evidence such as the IELTS score calculator, so the Diploma total is only one part of a profile.
