Method: GPA = Σ(grade points × credit hours) ÷ Σ(credit hours) on the standard 4.0 scale (A=4, B=3, C=2, D=1, F=0, with +/− steps of 0.3 where used).
How it works
Each letter grade maps to grade points (A is 4.0, B is 3.0, and so on). GPA is the total grade points weighted by credits, divided by the total credits:
GPA = sum of (grade points × credits) ÷ total credits
A course worth more credits has a larger effect on your overall GPA.
How to use the GPA Calculator
Enter the values requested by the tool and start with one realistic example. Read the result together with its unit or label, then change one input at a time if you want to compare options. Keeping a note of the original figures makes the calculation easier to check later.
Schools and universities can use different rules, weightings and grade boundaries. Compare the result with the instructions for your course or assessment.
