A GPA calculator works out your grade point average based on the grades and credit hours for each course you've taken, using the standard 4.0 scale most schools and colleges follow. Enter your grades and credits, and it calculates your semester or cumulative GPA instantly, weighted properly by how many credits each class was worth.
Averaging grades manually gets error-prone once credit hours differ between classes — a 3-credit A shouldn't count the same as a 1-credit A in the final average. This tool exists to handle that weighting correctly so you get an accurate GPA instead of a rough estimate.
GPA is calculated by converting each letter grade to grade points (A=4.0, B=3.0, C=2.0, etc.), multiplying by the credit hours for that course, summing those totals, and dividing by the total credit hours attempted. So an A (4.0) in a 3-credit class and a B (3.0) in a 4-credit class works out to (4.0×3 + 3.0×4) ÷ 7 = 3.43 GPA — not a simple average of 3.5, because the 4-credit class carries more weight.
Multiply each course's grade points by its credit hours, sum those values across all courses, then divide by total credit hours to get the weighted GPA.
Yes, higher credit courses carry more weight in the final GPA calculation than lower credit courses, even with the same letter grade.
Semester GPA covers only the current term's courses, while cumulative GPA factors in every course and credit hour across your entire academic record.
Yes, you can select or enter the specific grade point value for plus/minus grades if your school uses that grading scale.
You can work backward by testing different grade combinations for remaining courses to see what final GPA they would produce.
