Calculate your GPA (Grade Point Average) with weighted credit hours. Add your courses, select letter grades, and get your semester GPA instantly on the standard 4.0 scale.

How GPA Is Calculated

GPA is a weighted average: each letter grade converts to grade points (A = 4.0, B = 3.0, etc.), multiplied by the course's credit hours, then divided by total credits:

GPA = Σ(Grade Points × Credits) ÷ Total Credits

For example, an A (4.0) in a 3-credit course earns 12 grade points. A B (3.0) in a 4-credit course earns 12 grade points. Together: 24 points ÷ 7 credits = 3.43 GPA.

Standard 4.0 Grade 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 · F = 0.0

FAQ

What is a good GPA?
A 3.0 (B average) is generally considered good; 3.5+ is competitive for graduate programs; 3.7+ qualifies for honors at most universities.

How do I raise my GPA?
Higher-credit courses impact GPA more. Retaking a failed course (if your school replaces the grade) is the fastest way to improve it.

Does this work for high school?
Yes — the unweighted 4.0 scale is standard for US high schools. For weighted GPA (AP/IB classes), add 0.5-1.0 to honors grades manually.
