About This Calculator
The GPA Calculator computes your grade point average on the standard 4.0 scale by weighting each course grade by its credit hours. Enter as many courses as you need — the calculator instantly shows your GPA, total quality points, and total credits. This is the same formula used by most U.S. colleges and universities. Whether you are checking your semester GPA or calculating your cumulative average across multiple years, this tool gives you accurate results in seconds.

The Formula
How the calculation works under the hood
Grade Point Average (GPA)
Each course contributes quality points equal to its grade-point value multiplied by credit hours. The GPA is the weighted average across all courses.
Worked Example
Step-by-step walkthrough with real numbers
“A student takes three courses: English (A, 3 credits), Calculus (B+, 4 credits), and History (A-, 3 credits).”
- 1English: A = 4.0, quality points = 4.0 x 3 = 12.0.
- 2Calculus: B+ = 3.3, quality points = 3.3 x 4 = 13.2.
- 3History: A- = 3.7, quality points = 3.7 x 3 = 11.1.
- 4Total quality points = 12.0 + 13.2 + 11.1 = 36.3.
- 5Total credits = 3 + 4 + 3 = 10.
- 6GPA = 36.3 / 10 = 3.63.
The semester GPA is 3.63 on a 4.0 scale.
⚠️Common Mistakes
- ✕Using unweighted averages that treat a 1-credit lab the same as a 4-credit lecture.
- ✕Including pass/fail or audit courses that do not carry grade points.
- ✕Confusing a weighted high-school GPA (5.0 scale for AP/honors) with the standard 4.0 college scale.
💡Pro Tips
- ✓Many graduate programs expect a minimum 3.0 GPA, so recalculate after each semester to stay on track.
- ✓If your school uses +/- grading, an A- (3.7) is noticeably different from an A (4.0) over many courses.
- ✓Use this calculator each semester to decide whether retaking a low-grade course would meaningfully raise your cumulative GPA.
Frequently Asked Questions
What GPA scale does this calculator use?
It uses the standard 4.0 scale where A/A+ = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, and so on down to F = 0.0.
Can I calculate a weighted GPA?
Yes. Enter the credit hours for each course and the calculator weights each grade by those credits automatically. Courses worth more credits have a proportionally larger effect on your GPA.
How do I calculate my cumulative GPA?
Enter all courses from all semesters. The calculator totals your quality points and credits across every entry to produce one cumulative GPA.
What are quality points?
Quality points are calculated by multiplying the grade point value by the number of credit hours for a course. For example, a B (3.0) in a 4-credit course earns 12.0 quality points.
Can I include pass/fail courses?
Pass/fail courses do not carry grade points and should be excluded from GPA calculations. Only include courses with letter grades.
