About this calculator
GPA pages are useful because students often need a quick weighted average instead of a generic mean. Credits matter, so a dedicated GPA model is more practical than a plain average tool.
A fixed 4.0-scale version covers a broad student use case without forcing custom-grade math for every visit.
Frequently asked questions
Why does GPA differ from a normal average?
Because GPA weights each course by credits instead of treating every class as equal regardless of course load.
Will this match every school exactly?
Not always. Schools can use slightly different grade-point scales, so this tool is a standard 4.0 estimate.
Can I leave unused courses at zero credits?
Yes. Only rows with positive credits are counted in the result.
