GPA Calculator
Calculate your GPA on the standard 4.0 scale, weighted by credit hours.
Add each course with a letter grade and credit hours. The calculator returns your credit-weighted GPA on the standard 4.0 scale.
Enter your courses with grade and credit hours. Add or remove rows as needed.
How GPA is calculated
GPA (Grade Point Average) on the standard 4.0 scale is calculated by multiplying each course grade by its credit hours, summing those products, and dividing by total credit hours. This is called the credit-weighted average. A 4-credit A counts more than a 1-credit A.
The 4.0 scale (standard US)
- 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
This calculator uses the standard unweighted scale (4.0 max). Some high schools use a weighted scale that adds 0.5 or 1.0 to honors and AP courses (so a max could be 5.0 or higher). For weighted GPA, multiply the relevant grades by the weighting factor before entering, or check with your school for their exact scale.
What's a "good" GPA?
Context matters. For competitive college admissions, 3.5+ is typically expected (and 3.8+ for top schools). For graduate school, 3.5+ is the rough threshold. For most employers, GPA matters only at first hire, and many do not ask. Maintain good grades, but do not obsess over the third decimal place.
