GPA Calculator
Enter up to eight courses with a letter grade and credit hours to get your credit-weighted GPA on the standard 4.0 scale. Empty rows are ignored. For a single course's weighted average — or the score you need on a final — use the Grade Calculator.
Semester GPA
Example: A (3 cr), B (4 cr), A− (3 cr) → GPA 3.51.
How GPA is computed
Each letter grade maps to points (A = 4.0, A− = 3.7, B+ = 3.3 …), each course's points are multiplied by its credits, and the sum is divided by total credits. In the example above: (4.0 × 3 + 3.0 × 4 + 3.7 × 3) ÷ 10 = 3.51 — computed at build time by the same engine the calculator uses, so the page and the tool can never disagree.
Reading your GPA strategically
Because credits weight everything, protecting grades in high-credit courses matters most, and a weak grade in a small course dents the average less than it feels like it should. When targets loom (scholarship thresholds, honors cutoffs), compute the GPA you'd need in remaining credits rather than guessing — small credit loads late in a degree move a cumulative GPA surprisingly little.
Frequently asked questions
Why do credits matter and not just grades?
GPA is a weighted average: each grade’s points are multiplied by the course’s credit hours, summed, and divided by total credits. An A in a 4-credit course lifts your GPA more than an A in a 1-credit seminar.
What scale does this use — is A+ worth 4.3?
The standard US 4.0 scale, with A+ capped at 4.0 (the most common convention). If your school awards 4.3 for an A+, your official GPA may differ slightly; your transcript is always authoritative.
How do pass/fail courses count?
At most institutions, passed pass/fail courses earn credits but no grade points and are excluded from GPA. Leave them out of the calculator to match that convention.
Can I project next semester’s GPA?
Yes — enter your expected grades and credits for planned courses. To project a cumulative GPA, you would also need your current total credits and grade points; that richer mode is a planned addition.
