How Are IB Grades Calculated? (Full Breakdown)
The International Baccalaureate (IB) Diploma uses a unique points system. Your final IB grade is the sum of six subject scores (each from 1 to 7) plus up to 3 bonus points from the Extended Essay (EE) and Theory of Knowledge (TOK). The maximum total is 45 points. For 2026, grade boundaries vary slightly per subject, but the calculation method remains consistent.
🔢 Subject Scoring (1–7 scale)
Each HL (Higher Level) and SL (Standard Level) subject is graded internally and externally. A score of 7 equals "excellent," 4 is a passing grade, and below 4 is considered insufficient. Universities like Harvard, Stanford, and UCLA often look for 38+ points.
| IB Grade | Descriptor | Approx. GPA Equivalent |
|---|---|---|
| 7 | Excellent | 4.0 (A+) |
| 6 | Very good | 4.0 (A) |
| 5 | Good | 3.3 (B+) |
| 4 | Satisfactory | 2.7 (B-) |
| 3 | Mediocre | 2.0 (C) |
| 2 | Poor | 1.0 (D) |
| 1 | Very poor | 0.0 (F) |
⭐ How IB Core (EE/TOK) Bonus Points Work
The matrix below determines extra points: both EE and TOK are graded A–E. The combined result gives 0, 1, 2, or 3 bonus points. For example, AA = 3 points, AB/BA = 3 points, BB = 2 points, etc. A failing grade (E) in either component disqualifies the diploma.
- A + A → 3 points
- A + B / B + A → 3 points
- B + B → 2 points
- C + C or C + D → 1 point
- E in any component → 0 bonus, diploma at risk
How to Calculate IB Predicted Grades (2026 Tips)
Predicted grades are critical for early university applications. Teachers estimate your final score using internal assessments, mock exams, and class participation. To improve predictions: submit high-quality IAs, review past papers, and engage consistently. Use our ib predicted grades calculator above as a simulation — input your current performance to forecast your final IB points.
IB Grade Boundaries by Subject (Example)
Each subject has unique boundaries. For IB Math AA SL, a 7 might require 85%+ in 2026, while IB History HL may have lower thresholds. Always check your subject guide, but here’s a typical reference:
| Subject | 7 boundary (approx) | 6 boundary |
|---|---|---|
| IB Math AA HL | 82% | 73% |
| IB Biology HL | 78% | 68% |
| IB English A Lit SL | 80% | 70% |
| IB History HL | 75% | 65% |
GPA Calculator IB Grades: Convert IB to 4.0 Scale
US colleges require GPA. To calculate GPA from IB grades, convert each subject score: 7 → 4.0, 6 → 4.0, 5 → 3.3, 4 → 2.7, 3 → 2.0, 2 → 1.0, 1 → 0.0. Then average across 6 subjects, plus core points do not directly affect GPA but overall points reflect rigor. Our interactive tool above shows your estimated cumulative GPA instantly.
✅ Quick Checklist: How to Calculate Your Final IB Grade
- Add subject scores – sum your six 1-7 grades (max 42).
- Determine EE/TOK matrix points – use the official matrix (0–3).
- Add total – subject sum + core bonus = final IB points (max 45).
- Convert to GPA – map each subject grade to 4.0 scale, then average.
- Compare with university requirements – for 2026 admissions, 40+ is highly competitive.
