How GPA is calculated
Each letter grade maps to grade points (A = 4.0, B = 3.0, etc.). Multiply each course's points by its credit hours, sum everything, and divide by total credits: GPA = Σ(points × credits) ÷ Σ(credits). Credit weighting is why a B in a 4-credit course pulls your GPA more than an A in a 1-credit lab fixes it.
Standard 4.0 scale
| Grade | Points | Grade | Points |
|---|---|---|---|
| A+ / A | 4.0 | C+ | 2.3 |
| A− | 3.7 | C | 2.0 |
| B+ | 3.3 | C− | 1.7 |
| B | 3.0 | D | 1.0 |
| B− | 2.7 | F | 0.0 |
Scales vary: some schools give A+ 4.3, some use 4.33 or percentage-based scales, and Canadian universities differ by province. Check your institution's official conversion — this tool uses the most common US/Canada 4.0 mapping.
GPA milestones that matter
3.5+ typically qualifies for Dean's List and keeps scholarship options open; 3.0 is a common cutoff for grad school applications and many employers' screens; below 2.0 usually triggers academic probation. If you're recovering from a rough semester, remember: the more credits you've completed, the more slowly the cumulative moves — the calculator above shows exactly how much a strong semester shifts it.
