GPA Calculator
Add each course's grade and credit hours to get your weighted grade point average on the standard 4.0 scale.
How it works
Your GPA isn't just the average of your letter grades — it's weighted by how many credits each course is worth. A four-credit class pulls on your average twice as hard as a two-credit one, so both the grade and the credits matter.
Each grade maps to grade points on a 4.0 scale: A is 4.0, B is 3.0, C is 2.0, and so on, with the pluses and minuses in between. The calculator multiplies each course's points by its credits, adds those up, and divides by your total credits.
Add a row for every class and the GPA updates live. It's handy for checking where you stand mid-semester, or for seeing what grade you'd need in a remaining course to hit a target.
Frequently asked questions
How is GPA calculated?
Multiply each course's grade points by its credit hours, add all of those up, then divide by the total credit hours. That weighting is why a high grade in a big class helps more than one in a small class.
What is the grade point scale?
On the common 4.0 scale, A is 4.0, A- is 3.7, B+ is 3.3, B is 3.0, and so on down to F at 0.0. Some schools weight honors or AP courses higher, but the unweighted 4.0 scale is the standard.
Does the number of credits matter?
Yes, a lot. GPA is credit-weighted, so a strong grade in a four-credit course moves your average more than the same grade in a one-credit course. Enter accurate credit hours for each class.
