How GPA is Calculated
Our GPA calculator uses the standard weighted GPA formula:
Formula:GPA = (Sum of Grade Points × Credits) ÷ Total Credits
For example, if you earned an A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course:
Course 1: 4.0 × 3 credits = 12.0 grade points
Course 2: 3.0 × 4 credits = 12.0 grade points
Total grade points: 24.0
Total credits: 7
GPA = 24.0 ÷ 7 = 3.43
Frequently Asked Questions (FAQ)
What is GPA?
GPA stands for Grade Point Average. It is a numerical representation of a student's academic performance, calculated by averaging the grade points earned in all courses. Most schools use a 4.0 scale, but some use 5.0 for weighted honors courses.
How do I calculate my GPA?
Multiply each course's grade point by its credit hours, sum all grade points, then divide by total credit hours. Our GPA calculator does this automatically when you enter your grades and credits.
What is weighted vs unweighted GPA?
Unweighted GPA uses a standard 4.0 scale where A=4.0, B=3.0, etc. Weighted GPA gives extra points for honors, AP, or IB courses, often using a 5.0 scale where A=5.0. Weighted GPA reflects course difficulty.
What is a good GPA?
A GPA of 3.0 or higher is generally considered good. A 3.5+ is competitive for most colleges, while 3.7+ is excellent. For highly selective schools, a 3.8-4.0 weighted GPA is typically expected.
Does this calculator work for all schools?
Yes, our GPA calculator supports the most common scales (4.0, 5.0, and percentage). However, some schools may use unique grading systems, so always verify with your school's specific policy.
