IB Score Calculator (Out of 45)
Enter your six subject grades (1-7), choose HL/SL for each subject, and add your TOK/EE core points (0-3).
Note: Diploma status shown is an estimate using common IB checks. Always confirm final policy details with your IB coordinator.
How this IB score calculator helps
The IB Diploma Programme is scored out of 45 points: six subjects (up to 42 points total) plus up to 3 core points from Theory of Knowledge (TOK) and the Extended Essay (EE). This tool gives you a quick way to calculate your total and get a simple, practical estimate of your diploma standing.
Whether you are setting predicted grades, planning exam targets, or checking university application competitiveness, a clear points total is the first thing you need. Instead of adding numbers manually every time you adjust a subject score, you can run scenarios in seconds.
IB scoring basics (quick refresher)
1) Six subjects
Each IB subject is graded from 1 to 7. With six subjects, your subject total ranges from 6 to 42.
2) Core points
TOK and EE combine to award 0 to 3 points. CAS is required for the diploma but does not add numeric points.
3) Overall score
Final IB diploma score = subject points + core points, with a maximum of 45.
How to use the calculator effectively
- Enter all six subject grades using whole numbers between 1 and 7.
- Select HL or SL for each subject to estimate level-specific threshold checks.
- Enter TOK/EE core points from 0 to 3.
- Tick CAS completed if you have satisfied CAS requirements.
- Click Calculate IB Score to see your total and an estimated result message.
If you are still waiting on final results, use predicted values to model different outcomes. For example, compare your current expected score with a “stretch” scenario where one HL subject improves by 1 point.
What counts as a strong IB score?
Context matters by country, course, and university. As a general rule:
- 40-45: Outstanding and highly competitive globally.
- 35-39: Strong profile for many selective programs.
- 30-34: Good score range, competitive for many solid options.
- 24-29: Typical diploma pass territory, depending on full conditions.
Universities may also care about specific HL subject scores (for example, HL Math or HL Chemistry) rather than only the overall number.
Estimated diploma checks used in this page
The calculator includes practical checks often discussed by IB students and coordinators:
- Minimum total points threshold (24+).
- No grade 1 in any subject.
- No more than two grades of 2.
- No more than three grades at 3 or below.
- HL/SL combined minima based on your selected level mix.
- CAS completion check.
Rules can vary by session updates and specific circumstances. Treat this as a planning guide, not an official award decision.
Smart ways to raise your IB total
Focus on “high-leverage” subjects
Improving a 4 to a 5 can be more realistic than trying to jump from 6 to 7. Identify where a one-point gain is most achievable and prioritize that class.
Use weekly score tracking
Enter your current estimated scores each week. Watching your trend makes progress visible and helps you adjust revision strategy early.
Protect your core points
TOK and EE can be the difference between offers met and offers missed. A disciplined timeline for draft feedback can protect those points.
Build around exam command terms
Many students know content but lose marks on task interpretation. Practice command terms (evaluate, compare, justify, discuss) in timed conditions.
Common questions students ask
Can I get the diploma with exactly 24 points?
Sometimes yes, but only if all other diploma conditions are satisfied (including level thresholds and CAS completion).
Do universities only care about total points?
Not always. Many programs require specific HL grades in relevant subjects, so check entry requirements carefully.
Should I model best-case and worst-case scenarios?
Absolutely. Scenario planning reduces stress and gives you a concrete revision target for each subject.
Final thoughts
A good IB score calculator does more than add numbers. It helps you make smarter decisions: where to focus, what to improve first, and how close you are to your goal. Use this page as a practical planning tool, then verify all official outcomes through your school and IB coordinator.
