Formula: GPA = Σ(grade points × course credits) / Σcredits. The stored letter-grade scale runs from A+/A = 4.0 to F = 0; institution-specific rules may differ.
Variables: Grade points = numeric value of each letter grade
Credits = credit hours for each course
Units: Grade points: 4.0 scale
Course weight: credit hours
Example: A− (4 credits), B+ (3), B (4) and A (3) give a semester GPA of about 3.46.
Assumptions: Courses with positive credits are included. Confirm your institution’s treatment of repeats, pass/fail courses and plus/minus grades.
