How GPA Is Calculated
Grade Point Average (GPA) is a weighted average that accounts for both your letter grade and the credit hours of each course. A 4-credit A contributes more to your GPA than a 2-credit A. To calculate it, multiply each course's grade points by its credit hours, sum all the products, then divide by the total credit hours. This calculator uses the standard 4.0 scale adopted by most US colleges and universities.
GPA Formula
GPA = Σ(Grade Points × Credit Hours) / Σ(Credit Hours)
Scale: A+=4.0, 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
Weighted vs Unweighted GPA
An unweighted GPA uses the standard 4.0 scale for all courses. A weighted GPA adds extra points for honors, AP, or IB courses, often on a 5.0 scale. Colleges typically recalculate your GPA using their own scale, so focus on challenging coursework rather than gaming the number. Most scholarship applications specify which GPA type they require.
Why GPA Matters
GPA determines eligibility for Dean's List (usually 3.5-3.7+), Latin honors at graduation, graduate school admission, and many scholarships. Employers in competitive fields may use GPA as a screening filter for entry-level roles. A GPA below 2.0 at most institutions triggers academic probation. If your GPA is lower than your target, focus on higher-credit courses where improvement has the greatest impact on your cumulative average.
