College GPA Calculator

Each course's letter grade is converted to grade points on the US 4.0 scale, then multiplied by the course's credit hours to get quality points. Sum the quality points for every course, divide by total credit hours, and round to two decimals. Example: a 4-credit A (4.0) and a 3-credit B+ (3.3) gives (4 x 4.0 + 3 x 3.3) / 7 = 25.9 / 7 = 3.70. Quality points, not raw grade points, is the actual unit being averaged, which is why a 4-credit A pulls harder on your GPA than a 1-credit A.

Semester GPA covers only the courses you took in one term. Cumulative GPA is the weighted average of every GPA-bearing course you have completed at the institution. To update cumulative GPA after a new semester, multiply your prior GPA by your prior total credit hours, add the new semester's quality points, then divide by the new total credit hours. This calculator does that math for you in cumulative mode.

It supports A+ through F and maps A+ and A to 4.0, A- to 3.7, B+ to 3.3, and so on. That is the calculator's fixed mapping. Institutions differ on A+, plus/minus values, repeats, and non-letter grades, so verify the result against your registrar's policy.

This depends on your school's repeat policy. Three common approaches: replacement (only the new grade counts, the old attempt is excluded from GPA), averaging (both grades stay in GPA), and grade forgiveness (the old grade stays on the transcript but is excluded from GPA up to a fixed credit cap). To model a replacement-policy retake here, enter only the new attempt. To model an averaging policy, enter both attempts as separate courses. Check your registrar's catalog for the exact rule before relying on the number.

The calculator uses internal labels at 3.9, 3.5, 3.0, and 2.0. They do not determine Dean's List, President's List, Latin honors, or academic standing at your institution. Official rules may include minimum credits, excluded grades, or class-percentile thresholds.
