Calculate your University College Dublin GPA on the official grade-point scale (A+ = 4.2 down to NG = 0.0), weighted by ECTS credits, with the honours classification bands 1H, 2H1, 2H2 and Pass.
| Grade | Credits (ECTS) |
|---|
Enter each module's letter grade and its credit value — most UCD modules are 5 ECTS. GPA = Σ(grade point × credits) ÷ Σ(credits).

| A− | 3.8 | 70–73% |
| B+ | 3.6 | 66–69% |
| B | 3.4 | 62–65% |

| D+ (2.4) 5cr + C− (2.6) 5cr | 2.50 / 4.20 · 2H2 band |
| All B− (3.2) across 20 credits | 3.20 / 4.20 · 2H1 band |
| Classification | GPA band |

| First Class Honours (1H) | 3.68 – 4.20 |
| Second Class Honours, Grade 1 (2H1) | 3.08 – 3.67 |
| Second Class Honours, Grade 2 (2H2) | 2.48 – 3.07 |
| Third Class Honours (Pass) | 2.00 – 2.47 |
Every module grade converts to a grade point on a scale that tops out at 4.2, not 4.0 — that is the single most common source of confusion when UCD students compare themselves against US-style GPAs. An A+ earns 4.2 grade points per credit, so a perfect transcript reads 4.20, not 4.00.
UCD weights by ECTS credits, so a 5-credit module pulls your GPA exactly twice as hard as a 2.5-credit one. Before resitting or repeating anything, check the credit values: rescuing a 10-credit module from D to B lifts a 60-credit stage GPA by 0.20, while the same rescue on a 5-credit module lifts it by only 0.10.
The grade-point values (A+ 4.2 through NG 0.0) and the honours classification bands come from UCD's published grading scheme. The percentage column is a widely used guide, not an official UCD mapping — UCD does not publish a fixed grade-to-percentage table, and module boards set grade boundaries per assessment. Always confirm programme-specific rules (compensation, resits, which stages count toward your award GPA) with your school office.
UCD assigns A+ a grade point of 4.2, one step above A at 4.0, so the scale has extra headroom at the top. When comparing with US 4.0-scale GPAs, a rough conversion is to multiply the UCD figure by 4/4.2 (about 0.952), though no official conversion exists.
A GPA of 3.68 or higher on the 4.2 scale puts you in the First Class Honours band. Second Class Honours Grade 1 starts at 3.08, Grade 2 at 2.48, and a Pass at 2.00.
The commonly used guide is 40%, corresponding to a D grade (2.2 grade points). D− (2.0) and below are failing grades at module level, though some programmes allow compensation — check your programme regulations.
It depends on the programme. Many UCD honours degrees weight later stages more heavily (for example, counting only Stage 2 onward, or weighting the final stage most). The calculator here gives a plain credit-weighted average — apply your programme's stage weights separately.
NG means No Grade — the module was not successfully completed and carries 0.0 grade points, dragging the GPA like an F or G would.
