How the GPA calculation works
Each letter grade maps to grade points (A=4.0 down to F=0.0). The calculator multiplies each course's grade points by its credit hours, sums those values, and divides by the total credit hours. The result is a credit-weighted GPA, so a 4-credit course influences your average more than a 1-credit course.
Frequently asked questions
How is GPA calculated?
GPA is the credit-weighted average of your grade points. Multiply each course's grade points by its credit hours, add those products together, then divide by the total credit hours.
What grade points map to letter grades?
On a 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 the difference between weighted and unweighted GPA?
Unweighted GPA treats every course equally. Weighted GPA factors in credit hours so higher-credit courses count more. This tool computes a credit-weighted GPA.
Does this GPA calculator store my data?
No. All calculations run entirely in your browser. Nothing you enter is uploaded or saved on a server.
Can I add more than the default number of courses?
