How GPA is calculated
Grade Point Average converts letter grades into numbers on a 0–4.0 scale, then weights each by the course's credit hours so heavier courses matter more. Summing the weighted points and dividing by total credits gives your GPA. This tool accepts letter grades (A, B+, …) or raw grade points, one course per line.
