How the College GPA Calculator works
This college GPA calculator uses the standard 4.0 scale used by most US colleges and universities. Each course’s GPA value is weighted by its credit hours.
Drop your existing cumulative GPA + total credits into the Current GPA section and the calculator blends them with the current term to project your new cumulative.
Formula
GPA = Σ(gpa × credits) / Σ(credits)
Where
- gpa
- numeric value for each letter grade on your school's scale
- credits
- credit hours for that course (usually 3 or 4)
- Σ
- sum across all courses entered
FAQ
Common questions
What's the standard college GPA scale?
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 = 1.0, F = 0.0. Some schools count A+ as 4.0, others as 4.3 — customize via Grade Scale if needed.
How are credit hours weighted?
A 4-credit class affects your GPA more than a 1-credit class. The calculator multiplies each course's GPA value by its credits, sums them, then divides by total credits.
How do I figure out cumulative GPA after a transfer?
Add your prior cumulative GPA and total transferred credits in the Current GPA section. The calculator blends them with the courses you enter to give you a unified cumulative.
Does this work for graduate GPAs?
Yes — most grad programs use the same 4.0 scale. If yours uses something different, customize the values via Grade Scale.
What about withdrawn or pass/fail courses?
Withdrawn (W) courses usually don't affect GPA, so leave them out. Same with pass/fail unless your school explicitly factors them in.
