GPA 계산기

This calculator implements the standard 4.0 GPA scale used by most US colleges and universities. Grade points are assigned as: A/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, D- = 0.7, F = 0.0. GPA is calculated as a credit-weighted average: GPA = Σ(grade points × credit hours) / Σ(credit hours). This ensures that courses with more credit hours have proportionally greater impact on your GPA. Cumulative GPA combines all semesters: Sum all quality points (grade × credits) across all semesters and divide by total credit hours. Some institutions use variations: plus/minus grading, 5.0 scales for honors/AP courses, or different point assignments. This calculator uses the most widely adopted standard scale. Limitations: GPA scales vary between institutions and countries. Some schools do not use plus/minus grading. Graduate schools may weight grades differently. Pass/fail courses are typically excluded from GPA calculations. Transfer credits may or may not affect GPA depending on institutional policy.
