Your IB score estimate

Start with predicted or final grades from your teacher or IB results. Three subjects begin at HL and three at SL; change the levels to match your registration.

The session selects the supported assessment version; it does not supply official grade boundaries. For a component estimate, enter the boundaries provided for your subject, level and session. Otherwise use a teacher-provided subject grade.

Six registered subjects

Core requirements

The calculator checks common subject-group rules. Your DP coordinator must confirm language choices, interdisciplinary exceptions, permitted subject combinations and official registration. This checkbox records your confirmation; it does not verify a school record.

Enter six grades and the core requirements to begin.

IB score scale and pass conditions

The IB Diploma combines six subject grades, each from 1 to 7, and up to three core points. HL and SL grades contribute equally to the points total. The maximum is 6×7+3=45.

Total points=Six subject grades+TOK + EE core points

24 points is a minimum total, not a standalone pass guarantee. CAS completion, core grades, HL and SL totals and low-grade conditions must also be met. Read the IB passing criteria.

What is a good IB score?

A useful target depends on your course requirements, required HL grades and personal goals. Compare your plan with the university’s current offer conditions. A general “good score” band or an approximate GPA conversion cannot replace those requirements. Cohort averages also change by session; use the IB’s dated statistical bulletins for a measured average.

How to calculate and interpret your IB estimate

  1. Choose six subjects and their levels. Match your actual registration, with three or four HL subjects. Specify the language for an “Other Language” selection.
  2. Enter teacher-predicted or final grades. These give a transparent points estimate without guessing exam boundaries.
  3. Use component mode when appropriate. Verified presets cover Biology, Chemistry and Physics from first assessment 2025; current Mathematics AA/AI; and Language B or Spanish ab initio. Other subjects remain available through direct grade entry.
  4. Enter the core requirements. Choose TOK, EE and the actual CAS completion status. An E or N in the core cannot be treated as a successful zero-point result.
  5. Read every check. Compare HL/SL subtotals, low grades and school confirmation, then download the report. Recalculate after changing any input.

How component weighting works

Each component is normalized separately before weighting. m is the earned mark, M its maximum, and w the component’s percentage weight. W is the weighted total percentage.

W=∑miMi×wi

For current Biology, Chemistry and Physics, the combined Paper 1 contributes 36%, Paper 2 contributes 44%, and the scientific investigation contributes 20%. There is no Paper 3 in these first-assessment-2025 presets.

A worked component example

Suppose a practice assessment records Paper 1 at 4050, Paper 2 at 3050, and the investigation at 1520. These are example practice maxima, not claimed official paper maxima.

4050×36+3050×44+1520×20=70.2

The weighted result is 70.2%. A subject grade can be estimated only after applying the chosen boundary set. The calculator keeps full precision until display and labels illustrative boundaries as a planning model.

A worked 24-point diploma example

Six subject grades of 4, 4, 4, 4, 4 and 3 give 23 subject points. TOK C and EE C add one point, bringing the total to 24. With the first three grades at HL, the HL subtotal is 12; the remaining three SL grades total 11. If CAS is complete and the registered combination and other conditions are valid, the checked grade conditions are met. Use “Load a 24-point example” to inspect this case.

Why a high total can still miss the conditions

Three HL grades of 7 and SL grades of 3, 3 and 2 give only eight SL points. Even with three core points and a total of 32, the three-SL minimum of nine is not met. Four HL grades of 4, 4, 3 and 3 also miss the HL requirement because the best three total 11, not 12.

IB score calculator: frequently asked questions

For May sessions, schools receive results on 5 July and students access results from 6 July. For November sessions, schools receive results from 16 December and student access is from 17 December, with release times staggered by time zone. Your coordinator can confirm your exact access time. Check the IB assessment FAQ.

Add the six subject grades and the core points from TOK and EE. The maximum is 6×7+3=45. CAS contributes no points, but completion is required. Total points=Six subject grades+TOK + EE core points

Each graded subject uses a 1–7 scale. Six subjects contribute at most 42 points and TOK plus EE add at most three. A complete diploma points total is out of 45. A score estimate does not itself confirm a diploma award.

Use the exact course offer, required HL grades and institution policy for your entry year. There is no single “good score” or guaranteed-admission band that applies to every university. Begin with the diploma conditions, then set realistic subject and core targets.

The total must be at least 24. CAS must be completed, grades must be awarded in the subjects and core, and neither TOK nor EE may have an E. No subject may be grade 1; at most two subjects may be grade 2; and at most three may be grade 3 or below. The best three HL grades must total at least 12. Three SL subjects require at least nine points, or two SL subjects require at least five. School registration and other administrative conditions also apply. Official passing criteria.

Arrange transcript requests with your DP coordinator before results, checking the current deadlines and any free-request allowance. Additional requests after results use the IB’s transcript service and may involve fees. IB transcript request guidance.

The highest possible total is 45 points. A measured average must be tied to a named exam session; it should not be treated as a fixed score band or admissions threshold. IB statistical bulletins provide dated cohort results.

There is no universal official conversion that every institution uses. Follow the application’s instructions, report IB results in their original format when requested, and avoid presenting a calculator estimate as an institution-approved GPA.

HL courses have greater breadth and depth, with recommended teaching time of 240 hours, compared with 150 hours for SL. The diploma normally has three or four HL subjects and the remaining subjects at SL. HL and SL each contribute a grade from 1 to 7. Assessment components vary by subject and version; HL does not automatically mean a Paper 3.

Boundaries are the minimum marks for each grade in a specific subject and assessment. They can differ by subject, level, session and assessment variant. This tool does not provide authenticated session boundaries. Enter a documented matching set for a component estimate, or use a subject grade from your teacher or official results. Illustrative planning boundaries are explicitly labelled.

Requests go through your school’s DP coordinator. Category 1 is re-marking of externally assessed work; Category 2 provides copies of assessed material; Category 3 concerns re-moderation of an internal-assessment sample. A re-mark may lower or raise a grade, so discuss consent, fees and risk with your coordinator.

The IB’s 2026 Category 1 examiner instructions give the May window as 5 July to 15 September and the November window as 16 December to 15 March. These are Category 1 windows; schools may have earlier internal deadlines and service availability can differ. Do not assume a universal 15-day deadline or free service. IB 2026 Category 1 instructions.

Some institutions offer credit, placement or advanced standing for particular IB subjects and grades. Policies differ by course, level, department and entry year. Check the university’s own credit table and offer conditions; this calculator does not predict admissions or credit decisions.

Predicted grades are a school’s professional estimates of future performance. Teachers may consider coursework, internal assessments, mocks and other evidence. This calculator totals the inputs you provide; it does not create an official school prediction. Application deadlines and use of predicted grades vary by institution and entry cycle.

In addition to the normal diploma conditions, one route requires two group 1 languages with a grade of at least 3 in each. Another requires a group 3 or 4 subject studied in a language different from the group 1 language, with at least grade 3 in both qualifying subjects. This calculator does not verify teaching languages or award bilingual status. IB bilingual diploma criteria.

Use the weighting for the actual subject, level and assessment version. For the first-assessment-2025 Biology, Chemistry and Physics models, the scientific investigation is 20%. In current Mathematics AA/AI, the exploration is 20%. Moderated marks can differ from a teacher’s original mark. Component mode keeps each contribution separate instead of pooling unlike raw marks.

Discuss retake registration, the subjects available in the intended session, curriculum changes and any possible mark carry-forward with a DP coordinator. Do not assume all previous IA marks automatically carry forward or that all sessions offer every subject. Universities may have their own retake policies. IB retake and assessment FAQ.

Review the official result with your coordinator. A points total above 24 can still miss a core, CAS, HL, SL or low-grade condition. Depending on the case, discuss an enquiry upon results, retakes or the use of individual course results. None of those routes guarantees an improved grade or university place.

TOK and EE grades A–D combine to award zero to three points using the matrix below. C/C earns one point, A/D earns two, B/C earns two, and B/D earns one. D/D earns zero points and is not an automatic failing condition. An E or missing N grade prevents a successful core outcome.

No. The session selects the supported assessment period for component presets. It does not authenticate official boundaries, calibrate a prediction to that cohort, or change direct grades. For an unsupported subject/session model, use the subject grade supplied by your teacher or official results.

Calculate a valid report first, then download its CSV or print it. The CSV includes the displayed grades, core points, checked conditions, and any component marks and boundary labels. Editing an input invalidates the report and disables export until recalculation, so the downloaded data cannot silently refer to an older estimate.
