How GPA Is Calculated
Your GPA is the weighted average of your grades, where each course's grade points are multiplied by its credit hours.
GPA Formula
- Grade Points � Each letter grade corresponds to a numeric value (A = 4.0, A- = 3.7, B+ = 3.3, etc.)
- Quality Points � Grade points x credit hours for each course.
- GPA � Total quality points / total credit hours attempted.
- Weighted GPA � AP/IB courses get +1.0, Honors get +0.5 added to the grade point value.
- Cumulative GPA � Combines previous GPA (from prior semesters) with the current semester's GPA.
Frequently Asked Questions
Common questions about GPA calculation and grading scales.
Unweighted GPA uses a standard 4.0 scale where an A is always 4.0 regardless of course difficulty. Weighted GPA adds extra points for advanced courses: AP/IB courses typically get +1.0 (making an A worth 5.0) and Honors courses get +0.5 (making an A worth 4.5). This rewards students for taking more challenging coursework.
To calculate cumulative GPA: multiply your previous GPA by the number of previous credits to get your previous quality points. Then add your current semester quality points. Divide the total quality points by the total credits (previous + current). The result is your cumulative GPA across all semesters.
Dean's List requirements vary by school, but most universities require a semester GPA of 3.5 or higher on a 4.0 scale. Some schools also require a minimum number of credit hours (typically 12+) and may exclude courses graded as Pass/Fail.
Yes, plus and minus grades have different point values on the 4.0 scale: A+ = 4.0 (same 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. Not all schools use plus/minus grading, but this calculator supports the full range.
