GPA Calculator
Calculate your Grade Point Average (GPA) on a 4.0 scale. Add your courses, select grades, and enter credit hours. Supports cumulative GPA with previous semesters. See also Percentage Calculator.
Previous Semester (optional — for cumulative GPA)
How to Calculate GPA
GPA (Grade Point Average) is calculated by dividing the total number of grade points earned by the total number of credit hours attempted. Each letter grade corresponds to a numeric value on a 4.0 scale. Multiply each course's grade value by its credit hours to get grade points, sum all grade points, then divide by total credit hours.
GPA Formula
GPA = Sum of (Grade Points × Credit Hours) / Total Credit Hours
Example
Course A: A (4.0) × 3 credits = 12.0 points
Course B: B+ (3.3) × 4 credits = 13.2 points
Course C: A- (3.7) × 3 credits = 11.1 points
Total: 36.3 points / 10 credits
GPA = 3.63

Technical Details
This calculator uses the standard US 4.0 GPA scale used by most American colleges and universities. Some institutions use variations like a 4.3 scale (where A+ = 4.3) or weighted GPA scales for honors/AP courses. The cumulative GPA feature allows you to combine your current semester with previous semesters for an overall GPA. Latin honors thresholds vary by institution — the labels shown (Summa Cum Laude, Magna Cum Laude, Cum Laude) use common cutoffs but your school may differ.
Frequently Asked Questions
What is a good GPA?
A GPA of 3.0 or above is generally considered good. A 3.5+ is very good, and 3.7+ is excellent. For graduate school admissions, most programs expect a minimum of 3.0, with competitive programs looking for 3.5+.
How do I calculate cumulative GPA?
Multiply your previous GPA by previous total credits to get previous grade points. Add current semester grade points. Divide the combined total by combined credits. This calculator handles this automatically when you enter previous GPA and credits.
Does GPA include all courses?
Typically yes — GPA includes all graded courses. Some schools exclude pass/fail courses, transferred credits, or repeated courses (using only the higher grade). Check your institution's specific policy.
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 for honors, AP, or IB courses (e.g., an A in AP class = 5.0 instead of 4.0). This calculator uses the unweighted 4.0 scale.
