The GPA Formula
GPA = Total Quality Points ÷ Total Credit HoursQuality Points = Grade Point Value × Credit Hours for each course
Step-by-Step Guide to Calculating GPA
Convert letter grades to grade points
Use the standard 4.0 scale: A=4.0, B=3.0, C=2.0, D=1.0, F=0.0. For plus/minus grades, add or subtract 0.3 (A-=3.7, B+=3.3, etc.)
Multiply grade points by credit hours
For each course, multiply the grade point value by the number of credit hours. A B (3.0) in a 4-credit course = 3.0 × 4 = 12 quality points.
Sum all quality points
Add together all the quality points (grade points × credit hours) from all your courses.
Sum all credit hours
Add together the credit hours for all courses you're including in the calculation.
Divide total quality points by total credit hours
Your GPA = Total Quality Points ÷ Total Credit Hours. Round to two decimal places.

Worked Example
Let's calculate the GPA for a student with these courses:
| Course | Grade | Grade Points | Credits | Quality Points |
|---|---|---|---|---|
| English 101 | A | 4.0 | 3 | 12.0 |
| Math 201 | B+ | 3.3 | 4 | 13.2 |
| History 101 | A- | 3.7 | 3 | 11.1 |
| Chemistry 101 | B | 3.0 | 4 | 12.0 |
| Art 100 | A | 4.0 | 2 | 8.0 |
| Totals | 16 | 56.3 | ||
GPA Calculation
56.3 ÷ 16 = 3.52
This student's semester GPA is 3.52, which is an A-/B+ average.
Pro Tips for GPA Success
Focus on High-Credit Courses
A 4-credit course has twice the impact on your GPA as a 2-credit course. Prioritize doing well in courses with more credits.
Track Your GPA Regularly
Don't wait until the end of the semester. Calculate your GPA periodically so you can identify areas needing improvement.
Understand Your School's Scale
Some schools use different scales or don't include +/- grades. Check your institution's grading policy to calculate accurately.
Consider Grade Replacement
Many schools allow you to retake a course and replace the old grade. This can significantly improve your GPA if you received a low grade.
