How GPA is calculated
GPA stands for Grade Point Average. Each course's letter grade converts to a numeric point value (A = 4.0, B = 3.0, and so on), then that value is multiplied by the number of credit hours for the course. Sum those products across all courses, divide by total credit hours, and you get your GPA.
Weighted high school GPA adds a bump to honors and advanced courses before averaging: AP and IB courses add 1.0 point, Honors courses add 0.5. A student who earns a B in AP Chemistry (3.0 + 1.0 = 4.0 weighted) is recognized for the harder course load.
Unweighted GPA treats every course equally regardless of difficulty, maxing out at 4.0. Many colleges recalculate submitted GPAs on an unweighted scale to compare applicants fairly.
Letter grade to GPA point conversion
The standard 4.0 scale: 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. Some schools use percentage-to-letter cutoffs that differ slightly — this calculator uses the most common US standard.
