How GPA works
GPA is a credit-weighted average of your grade points. Each letter grade maps to a point value (A = 4.0, B = 3.0, etc.), which is multiplied by the course's credit hours to give quality points. Your GPA is the total quality points divided by the total credits.
Worked example
An A in a 3-credit class (4.0 × 3 = 12), a B+ in a 4-credit class (3.3 × 4 = 13.2), and an A- in a 3-credit class (3.7 × 3 = 11.1) give 36.3 quality points over 10 credits — a GPA of 3.63.
The formula
GPA = (Σ grade points × credits) ÷ (Σ credits)
Frequently asked questions
How is GPA calculated?
Multiply each course's grade points by its credit hours to get quality points, add up all quality points, and divide by the total credits. The result is your grade point average on a 4.0 scale.
What is the 4.0 grade scale?
A standard unweighted scale assigns A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, and so on down to F = 0.0. This calculator uses that scale by default.
What's the difference between weighted and unweighted GPA?
An unweighted GPA caps at 4.0 regardless of course difficulty. A weighted GPA gives extra points for honors or AP classes (often up to 5.0). This tool calculates unweighted GPA.
How do credit hours affect my GPA?
Courses with more credits count more toward your GPA. An A in a 4-credit class moves your average more than an A in a 1-credit class, which is why credits are part of the calculation.
