What this tool helps you find
Enter each course’s credit amount and letter grade. Each course contributes its grade points multiplied by its credits, so larger courses count more.
Formula
GPA = sum(grade points × credits) ÷ sum(credits).
Worked example
A 4.0 grade in a 3-credit class and a 3.0 in a 1-credit class gives a 3.75 GPA.
Common mistake
Schools use different grading scales and may assign different points to plus and minus grades. This calculator uses the common 4.0 scale shown beside the inputs.
When to use it
Estimate a term GPA from course grades or understand how a higher-credit class affects the average.
Questions and answers
Is the grading scale universal?
No. Institutions vary. This calculator uses a common unweighted 4.0 scale.
Why do credits matter?
Credits weight courses by their contribution to the overall study load.
