Each course's grade point is multiplied by its credits, and the total is divided by the total credits — so a heavier course moves your GPA more than a lighter one. Enter each subject's grade and credit to get the weighted average.
Grade-point scales (4-point, 10-point) and grade-to-point mappings differ by institution, and some drop or round in specific ways. Match your university's official scheme when the number matters for a transcript.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
