How this calculator works
What it estimates
Calculate semester GPA from courses, grades, and credit hours on a U.S. 4.0 scale.
Formula and example
- Each course grade is converted into grade points, multiplied by credit hours, and divided by total credits. GPA = total quality points / total credit hours.
- If you earn an A in a 4-credit class, a B+ in a 3-credit class, and an A- in a 3-credit class, the calculator averages those weighted quality points into one semester GPA.
