How to Calculate Cumulative GPA (Step-by-Step 2026 Guide)
Your cumulative GPA represents the average of all grade points across every course you've taken, weighted by credit hours. Whether you're a high school student aiming for college admission or a college student tracking graduation honors, understanding how to calculate cumulative GPA is essential. Most US institutions use the unweighted 4.0 scale, though some high schools use weighted scales for AP/IB. Our cumulative GPA calculator follows the standard 4.0 method.
📐 The Formula: (Total Grade Points) ÷ (Total Credit Hours)
For each course: Grade points (based on letter grade) × Credit hours = Quality points. Sum quality points across all courses, then divide by total attempted credits. To include previous semesters: [(Current GPA × Current Credits) + (New Quality Points)] ÷ (Current Credits + New Credits).
