GPA Formula & Grade Scale
GPA = Total Quality Points ÷ Total Credit Hours
Quality points for a course = grade value × credit hours. Standard 4.0 scale: 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, F=0.0.
Worked Example
Three courses: A (4.0) × 3 credits = 12.0 points; B (3.0) × 4 credits = 12.0 points; C+ (2.3) × 3 credits = 6.9 points. Total = 30.9 points ÷ 10 credits = 3.09 GPA.
Frequently Asked Questions
What is a good GPA in college?
Generally, 3.0 (B average) is considered good, 3.5+ is very good, and 3.7+ is excellent. Many scholarships require 3.0–3.5, and competitive graduate programs often look for 3.5+. Standards vary by school and major.
What is the difference between weighted and unweighted GPA?
Unweighted GPA uses the standard 4.0 scale for all courses. Weighted GPA gives extra points (often up to 5.0) for honors, AP, or IB courses to reflect their difficulty. This calculator uses the unweighted 4.0 scale.
How can I raise my GPA?
Focus on high-credit courses first — they move the average most. Retake failed courses if your school replaces the grade, prioritize classes where you're close to the next letter grade, and reduce your course load if you're stretched thin.
