How GPA is calculated

Both GPAs use course credits, so a half-credit class counts half as much as a full-credit class.

UnweightedΣ (grade points × credits) ÷ total credits
WeightedΣ ((grade points + course weight) × credits) ÷ total credits

Schools set their own grade scales and course weights. Adjust the example weights above to estimate your school's policy.

GPA calculator FAQ

Can my weighted GPA be over 4.0?

Yes. This calculator does not cap weighted GPA. Your school decides which grades and courses receive extra points.

What if a course is worth half a credit?

Enter 0.5 credits. Each course's contribution is multiplied by its credit value.

Does this calculator save my grades?

No. Your course details stay in this browser while you use the calculator and are not sent to a server.
