How This GPA Calculator Works
Each letter grade is converted to grade points on the standard 4.0 scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0), multiplied by the course's credit hours, then divided by your total credit hours. This student mark calculator gives you an instant, accurate semester GPA with no manual math needed.
Who Should Use This GPA Calculator
This tool is for students who want to know their semester GPA before it's officially posted, or who are planning ahead and want to see how a future course load might affect their overall average. It works for high school, college, and university grading scales that follow the standard 4.0 system.
FAQ
Does this work for a weighted GPA scale?
This calculator uses the standard unweighted 4.0 scale. If your school uses a weighted scale for honors or AP classes, adjust the grade points accordingly before entering them.
Can I use this to plan a future semester, not just calculate a finished one?
Yes. Enter your expected grades for upcoming courses to see a projected GPA before the semester ends.
