GPA Calculators
Nine calculators covering the GPA questions students actually ask — what my GPA is now, what one more semester does to it, what I need to reach a goal, and what happens if I retake a course.
All of them work on the grading scale you choose, because there is no single GPA formula in the United States. Every tool here is free, works without an account, and shows its working so you can check the answer.

How GPA actually works
A GPA is an average of your grade points weighted by credit hours. Each course is worth its grade points multiplied by its credits — that product is called quality points — and your GPA is the total quality points divided by the total credits.
That division by credits is the step most hand calculations get wrong. A four-credit course moves your GPA twice as much as a two-credit course with the same grade, so a plain average of your letter grades will usually differ from your real GPA.
It is also why a cumulative GPA becomes harder to move as you go. Fifteen new credits against sixty existing ones is a fifth of the total — even a perfect semester shifts the overall figure by a fraction of the gap.
There is no standard US grading scale
Schools calculate GPA differently
Institutions differ on whether plus and minus grades carry separate values, whether an A+ is worth more than 4.0, how pass/fail and transfer credits are treated, and what happens when a course is repeated. Two accurate GPAs for the same student can differ noticeably.
Every calculator here lets you pick the scale. The common 4.0 scale with plus and minus grades is the default because it is widely used, not because it is official. If yours differs — no plus/minus, or an A+ worth 4.3 — switch it before relying on the answer.
Your transcript is the authoritative record. These are planning tools.
