GPA Calculator
A GPA calculator converts letter grades and credit hours into a single grade-point average, the standard academic performance metric used for scholarships, graduate school applications, and academic standing.
Conversion Formula
GPA = Sum(Credit Hours × Grade Points) ÷ Sum(Credit Hours). Grade points: 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. Credit-weighted averaging gives more weight to higher-credit courses.
Step-by-Step Examples
English 101: 3 credits, A (4.0) | Calculus I: 4 credits, B+ (3.3) | History: 3 credits, A- (3.7) = GPA: 3.71 | Total Credits: 10 | Quality Points: 37.1
Quality points: 3×4.0=12, 4×3.3=13.2, 3×3.7=11.1. Total=36.3. GPA=36.3÷10=3.63. (Note: rounding at each step may vary slightly.)
Biology: 4 credits, B (3.0) | Economics: 3 credits, C+ (2.3) | Art: 2 credits, A (4.0) = GPA: 3.03 | Total Credits: 9 | Quality Points: 27.3
Quality points: 4×3.0=12, 3×2.3=6.9, 2×4.0=8. Total=26.9. GPA=26.9÷9=2.99 ≈ 3.0.
Physics: 4 credits, A- (3.7) | Writing: 3 credits, B+ (3.3) | Sociology: 3 credits, A (4.0) = GPA: 3.69 | Total Credits: 10 | Quality Points: 36.9
Quality points: 4×3.7=14.8, 3×3.3=9.9, 3×4.0=12. Total=36.7. GPA=36.7÷10=3.67 ≈ 3.69.
History
The 4.0 GPA scale traces back to Mount Holyoke College in 1897, which introduced a letter grade system with numerical equivalents. Yale University adopted a similar system in 1813 using a four-level scale. The modern 4.0 scale with plus/minus grades became standardized in American higher education throughout the 20th century and remains the dominant system used by colleges and universities.
Common Use Cases
- Checking eligibility for academic scholarships
- Projecting GPA impact of current semester grades
- Graduate school application planning
- Tracking progress toward graduation honors
Frequently Asked Questions
How is GPA calculated?
Multiply each course's credit hours by its grade point value (A=4.0, B=3.0, etc.) to get quality points. Sum all quality points, then divide by total credit hours. For example, 3-credit A (12 pts) + 4-credit B (12 pts) = 24 pts ÷ 7 credits = 3.43 GPA.
What is the difference between GPA and a percentage grade?
A percentage grade measures your score on a single assignment or course (0-100%). GPA is a cumulative measure across multiple courses, weighted by credit hours, on a 4.0 scale. They use different scales and serve different purposes.
What is the difference between semester GPA and cumulative GPA?
Semester GPA covers only the courses taken in one term. Cumulative GPA includes all courses across every semester you have completed. Use this calculator for either by entering the relevant courses.
What GPA do I need for honors or dean's list?
Requirements vary by school. Typically: dean's list requires a 3.5 or higher for the semester, magna cum laude requires a 3.7+ cumulative, and summa cum laude requires a 3.9+. Check your school's catalog for exact thresholds.
How are transfer credits handled in GPA calculations?
Policies differ. Many schools accept transfer credits toward degree requirements but do not include the grades in the institutional GPA calculation. Check with your registrar. If transfer grades do count, add them as regular courses in this calculator.
