Add each course with its letter grade and credit hours to compute your grade point average on the standard 4.0 scale.
Standard 4.0 scale: A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D+=1.3, D=1.0, F=0.0.
What is a GPA calculator? A GPA calculator computes your grade point average on the standard 4.0 scale from your course letter grades and credit hours.
Multiply each course's grade points by its credit hours to get quality points, add up the quality points for all courses, then divide by the total credit hours: GPA = sum of (grade points × credits) ÷ sum of credits.
On the standard 4.0 scale: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, and F = 0.0.
Credit hours are the weight of a course (often 3 or 4). Quality points are a course's grade points multiplied by its credit hours. Your GPA is total quality points divided by total credit hours, so higher-credit courses affect it more.
