How it's calculated
GPA = Σ (grade points × credits) ÷ Σ credits A = 4.0 · A− = 3.7 · B+ = 3.3 · B = 3.0 … D− = 0.7 · F = 0
Each grade becomes points on the 4.0 scale, weighted by the course's credit hours, and the total is divided by all credits. Some schools count A+ as 4.3; pick that with the switch. Pass/fail courses usually carry no grade points, so leave them out.

About the GPA calculator
This GPA calculator works out your grade point average on the 4.0 scale used by most US high schools and colleges. List each course with its letter grade and credit hours. It turns each grade into grade points, weights them by credits, and divides by your total credits. It shows the GPA together with your total credits, total grade points and number of courses. Some schools count an A+ as 4.3 instead of 4.0; switch that on if yours does. Pass/fail courses usually carry no grade points, so leave them out. Your school's own calculation, including any weighting for honors or AP classes, is the official one. The average calculator and weighted average calculator are useful for other kinds of grade averages.
How to use it
- In “Courses”, type one course per line: the letter grade, then the credit hours, for example A 3 or B+ 4. A course name in front, like Biology A- 4, is fine.
- Under “A+ counts as”, choose 4.0 or 4.3 to match your school.
- Read your GPA, then your total credits, total grade points and number of courses.
Worked example
Four courses: A (3 credits), B+ (4), A− (3) and C (2). The grade points are 4.0 × 3 + 3.3 × 4 + 3.7 × 3 + 2.0 × 2 = 40.3, over 12 credits, so the GPA is 40.3 ÷ 12 ≈ 3.36.

Questions people ask
How do I calculate my GPA?
Multiply each course's grade points by its credit hours, add those up, and divide by the total credit hours. GPA = Σ (grade points × credits) ÷ Σ credits.
What are the grade points for each letter grade?
On the 4.0 scale used here: A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, and so on down to D− = 0.7 and F = 0. Some schools count A+ as 4.3.
Why do credit hours matter?
A course with more credits counts for more of your GPA. A B+ in a 4-credit course pulls your average further than the same grade in a 2-credit course.
Should I include pass/fail classes?
Usually not. Pass/fail courses don't carry grade points at most schools, so leave them out of the list.
Is this my official GPA?
No. Schools differ on A+ values, weighting for honors or AP courses, and repeated classes. Your registrar or school counselor has the official figure.
