Frequently Asked Questions

Simple vs credit-weighted GPA?

This tool is credit-weighted: grade points × credits, summed, divided by total credits — a 4-credit A moves the result more than a 2-credit B. Use the college GPA calculator when you also need cumulative totals across semesters.

Which tool should I use?

Quick single-semester checks here; multi-semester running totals belong in the college GPA calculator. Know which number you're reporting.

Grade points?

A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D+=1.3, D=1.0, F=0 — the exact steps this tool uses. Unknown letters count as 0, so spell grades carefully.

Are grades uploaded?

No — math runs locally in your browser. Grades never leave your device.
