A GPA calculator helps students estimate their Grade Point Average based on course grades and credit hours. GPA is one of the most important indicators of academic performance in both high school and college.
Most US schools use a 4.0 scale, where an A equals 4.0 and an F equals 0. Some institutions use weighted scales like 5.0 or 10.0, especially for honors or AP courses.
Your GPA is calculated by dividing the total grade points earned by the total number of credits attempted.
Where Grade Points = Grade Value × Credit Hours per course

| Mathematics | A | 3 | 12.0 |
| English | B+ | 3 | 9.9 |
| History | A- | 3 | 11.1 |
| Total | 9 | 33.0 | |
