How the GPA Calculator Works
GPA is a credit-weighted average of grade points, not a plain average. Each letter grade maps to a point on the 4.0 scale (A = 4.0, A− = 3.7, B+ = 3.3, down to F = 0.0), each course’s point is multiplied by its credit hours to give quality points, and the GPA is the sum of quality points divided by the total credit hours. AnyTool computes both the unweighted GPA and a weighted GPA live in the browser.
- Unweighted GPA = Σ(grade point × credits) ÷ Σcredits
- Quality points = grade point × credit hours per course
- Letter grades mapped on a standard US 4.0 +/− scale
- Total credits and quality points shown alongside the GPA
- All math is client-side JavaScript with no server round-trip
