Course Grade Calculator

Multiply each category's score by its weight percentage and sum all results. Example: Homework 90% × 20% = 18 points. Tests 82% × 50% = 41 points. Add all weighted contributions for your overall grade percentage, which converts to a letter grade.

Weights must total exactly 100% for accurate results. If they don't sum to 100%, the result will be incorrect. The calculator shows a running weight total and warns you when weights don't reach 100%. Adjust until they equal exactly 100%.

Switch to "By Assignments" mode. Enter points earned and total possible per assignment — for example 47/50 on a quiz. The calculator totals all earned and possible points for your overall percentage.

Your grade can shift by the combined weight of all uncompleted assignments. If 30% remains undetermined (25% final + 5% homework), your grade can change by up to 30 percentage points in either direction from your current standing.

Most common scale: A+=97-100%, A=93-96%, A-=90-92%, B+=87-89%, B=83-86%, B-=80-82%, C+=77-79%, C=73-76%, C-=70-72%, D+=67-69%, D=63-66%, D-=60-62%, F=below 60%. Exact cutoffs vary — always check your syllabus.

Yes — the calculator tracks percentage in any course. Since pass/fail grades don't affect GPA, the letter grade conversion is less relevant. Most institutions set the pass threshold at 60-70%. Check your syllabus for the exact passing requirement.
