How the College GPA Calculator works
College GPA is a weighted average: each course's grade points (A = 4.0, A- = 3.7, B+ = 3.3, and so on) are multiplied by its credit hours, summed into quality points, and divided by total credits. A 4-credit A pulls your GPA twice as hard as a 2-credit A.
GPA = Σ(grade points × credits) / Σ(credits)
The cumulative section applies the same math across your whole transcript: your existing quality points (current GPA times completed credits) plus this semester's, divided by all credits combined. That is exactly how the registrar updates your record each term.
Frequently asked questions
How do I calculate my college GPA by hand?
Convert each grade to points (A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, down to F = 0), multiply by that course's credit hours, add everything up, and divide by total credit hours attempted.
Do plus and minus grades affect GPA?
At most colleges yes: a minus subtracts 0.3 and a plus adds 0.3, except A+ which usually still counts 4.0. Check your school's scale since a few use different steps or no plus-minus at all.
How much can one semester move my cumulative GPA?
It depends on how many credits you already have. With 15 credits completed, a strong semester moves your cumulative GPA a lot; with 90 credits, even a 4.0 term nudges it only slightly. The calculator shows the exact effect.
Do pass/fail classes count toward GPA?
Usually not: a Pass earns credits but no grade points, so it does not enter the GPA math at most schools. A Fail often does count as 0.0. Confirm your institution's policy.
