About this calculator
A GPA calculator turns your letter grades and the credit hours of each course into a grade point average on the standard US 4.0 scale. Each grade is converted to its point value (A = 4.0, B = 3.0, and so on), multiplied by the course credits, and the total is divided by the total credits. Fill in the courses you took this term — extra course rows are under advanced options.
Frequently asked questions
How is GPA calculated?
Multiply each course grade point (A = 4.0, B = 3.0, C = 2.0, and so on) by the course credit hours to get quality points, add those up across all courses, and divide by the total credit hours. A course worth more credits pulls the average more strongly.
What is the difference between weighted and unweighted GPA?
This tool computes an unweighted GPA on the standard 4.0 scale. A weighted GPA adds extra points for honors or AP/IB classes (often on a 5.0 scale), so it can exceed 4.0. Use your school’s scale if it weights advanced courses.
Can I add more than six courses?
Yes — open advanced options to reveal courses four through six. Leave a grade set to “skip” to exclude that row, and it will not count toward your credits or average.
