What This Calculator Does
This GPA calculator computes your semester Grade Point Average on the standard 4.0 scale used by most US colleges and universities. It accepts multiple courses with individual grades and credit hours, and optionally calculates cumulative GPA when you provide your existing GPA and credit total. The tool supports the full letter grade range from A+ to F.
The Formula
Each letter grade corresponds to a numeric value on the 4.0 scale (A = 4.0, B = 3.0, etc.). Quality points for each course equal the grade points multiplied by the credit hours. The GPA is the sum of all quality points divided by total credit hours.
Step-by-Step Example
Enter your courses
Add each course with its name, letter grade, and credit hours. Example: Calculus I, grade B+, 4 credits.
Add all courses for the semester
Include every course you are taking. Example: 5 courses totaling 15 credits.
Optional: enter existing GPA
To calculate cumulative GPA, enter your current GPA and total credits earned before this semester.
Review results
With grades of A (4cr), B+ (3cr), A- (4cr), B (3cr), A (2cr): semester GPA = 3.59.

Common Mistakes to Avoid
Forgetting that A+ and A both equal 4.0 on the standard scale. Some institutions may use a 4.3 scale for A+.
Not weighting by credit hours. A 4-credit course impacts your GPA twice as much as a 2-credit course.
Confusing semester GPA with cumulative GPA. Semester GPA only covers the current term.
Including pass/fail or audited courses that do not count toward GPA.
