How the GPA calculator works
Enter the letter grade and credit hours for each course and the tool computes your grade point average. It multiplies each course grade by its credit hours to get quality points, adds those up, and divides by your total credit hours. Leave rows blank if you have fewer courses; only rows with credit hours are counted.
Grade points and credit hours
GPA uses a four point scale where an A is 4.0, a B is 3.0, and so on, with pluses and minuses in between. Courses worth more credit hours weigh more heavily, which is why a strong grade in a four credit course moves your GPA more than the same grade in a one credit course. The tool uses the common plus and minus values shown in the dropdowns.
Weighted by credits
Because the average is weighted by credit hours, your GPA is not simply the average of your letter grades. Quality points, the grade times the credits, are what get summed. The tool shows your total quality points and credits so you can see exactly how the number is built and spot which courses pull it up or down.
Using your GPA
Use it to track standing, check whether you are on pace for honors thresholds like a 3.5, or model what a target grade would do to your average. Note that schools vary: some use a different scale, weight honors or AP courses higher, or exclude pass or fail courses, so treat this as a standard estimate.
Frequently asked questions
How is GPA calculated? Multiply each grade by its credit hours, sum those quality points, and divide by total credit hours.
Why is my GPA not the average of my grades? Because it is weighted by credit hours, so higher credit courses count more.
Does it handle plus and minus grades? Yes, the dropdowns include the standard plus and minus point values.
