Formula & How It Works

Semester GPA

GPA = Σ(Grade Points × Credit Hours) / Σ(Credit Hours)

Multiply each course grade points by its credit hours, sum those quality points, then divide by total credit hours.

Quality Points

Quality Points = Grade Points × Credit Hours

Each course contributes quality points equal to its letter grade points times how many credit hours it is worth.

Cumulative GPA

Cumulative GPA = (Current GPA × Completed Credits + New GPA × New Credits) / (Completed Credits + New Credits)

Combine your existing GPA and credit history with a new semester to get an updated overall GPA.

Practical Examples & Common Use Cases

Example: Semester GPA with three courses

A (4.0) × 3 credits = 12, B+ (3.3) × 3 credits = 9.9, A- (3.7) × 3 credits = 11.1. Total quality points = 33, total credits = 9. GPA = 33 / 9 = 3.67.

Example: Cumulative GPA update

Current GPA 3.50 over 60 credits, plus a new semester GPA of 3.80 over 15 credits: (3.50×60 + 3.80×15) / (60+15) = (210 + 57) / 75 = 267 / 75 = 3.56.
