Free Cumulative GPA Calculator for College, High School, and Middle School
This free cumulative GPA calculator helps students find their grade point average using course grades alone or with optional credit hours. It works as a GPA calculator with current GPA — enter your existing GPA and completed credits to get your updated cumulative GPA after this semester. It also works as a middle school GPA calculator without credits, since credits default to 1 per course when your school does not use formal credit hours.
The calculator converts letter grades to grade point values (A = 4.0, B = 3.0, and so on), multiplies each by the course credit value, sums all results, and divides by total credits. If you are using it as a semester GPA calculator for college, add each course with its credit hours and the tool handles all the weighted math automatically. No manual formula work needed.
Everything runs in your browser — no signup, no account, no data sent to any server. Results appear instantly as you enter grades.
