About the Waterloo Grading System
The University of Waterloo does not use a GPA. Since Fall 2001, all faculties report averages as percentage marks on a 0–100 scale — more precise than letter grades. Your transcript shows numeric averages, not GPA.
For external use (graduate school applications, US employers, study-abroad transfers), these percentages are converted to the standard Ontario 4.0 letter-grade scale. This calculator uses that conversion. Note that each institution may apply slightly different cutoffs — always check the admissions office of the program you're applying to. See our percentage-to-GPA guide for the full conversion table.
| Letter Grade | Grade Points | Waterloo % |
|---|---|---|
| A+ | 4.0 | 90–100 |
| A | 4.0 | 85–89 |
| A− | 3.7 | 80–84 |
| B+ | 3.3 | 77–79 |
| B | 3.0 | 73–76 |
| B− | 2.7 | 70–72 |
| C+ | 2.3 | 67–69 |
| C | 2.0 | 63–66 |
| C− | 1.7 | 60–62 |
| D+ | 1.3 | 57–59 |
| D | 1.0 | 53–56 |
| D− | 0.7 | 50–52 |
| F | 0.0 | 0–49 |

How Waterloo % is converted to GPA
The calculator above works in two steps:
- Convert each percentage to a 4.0 grade point using the table above.
- Compute the credit-weighted average:
GPA = Σ (grade points × course weight) ÷ Σ course weights
Each course contributes grade points × weight (weight = course's unit count). CR/NCR courses add weight but no grade points and are excluded from the GPA. The same formula is used by admissions offices; the only variable is the cutoff table.
Other Canadian university GPA calculators
Most Canadian universities use a 4.0 GPA scale with slight variations. See how others handle it:
- University of Toronto — refined 4.0 scale, A+ = A = 4.0
- UBC — one of the few with A+ = 4.33
- McGill — no A+, no C−/D+/D− grades
- University of Alberta — 4.0 with F4 reexamination option
