About
Grade Point Average miscalculation is a common cause of missed dean's list placements, scholarship disqualifications, and failed graduate school applications. A single wrong credit-hour entry or misunderstood grade scale shifts your cumulative GPA by tenths of a point. This calculator implements the standard 4.0 quality-point scale used by most U.S. colleges (per AACRAO guidelines), computing GPA as the credit-weighted mean of grade points: GPA = Q รท C, where Q is total quality points and C is total credit hours attempted. It handles plus/minus grading, multi-semester tracking, and real-time cumulative aggregation.
Limitation: this tool assumes a uniform 4.0 scale. Some institutions cap A+ at 4.3 or use a 5.0 weighted scale for honors courses. Verify your institution's specific policy. Pass/Fail and Incomplete grades are excluded from GPA computation, consistent with standard registrar practice. Repeated courses require manual adjustment; only the final attempt grade should be entered.
Formulas
The Grade Point Average is a credit-weighted arithmetic mean. For a single semester containing n courses:
Where ci = credit hours for course i, and gi = grade points for course i (looked up from the 4.0 scale table). Cumulative GPA extends across all semesters s = 1 to S:
Where Qs = total quality points for semester s, and Cs = total credit hours attempted in semester s. Quality points for a course: Qi = ci ร gi. Grades of P (Pass), W (Withdraw), or I (Incomplete) carry 0 quality points and 0 attempted credits.
