Accurate weighted grade calculation
Most courses weight assignments differently. A simple average of your scores will not match your real grade. This tool calculates the true weighted average so you know exactly where you stand.
The weighted grade calculator computes your overall course grade when assignments carry different percentage weights. Add each grade and weight in a clear row to get your weighted average percentage and letter grade. Used by students tracking grades across homework, quizzes, midterms, and finals with different syllabus weights.

Weighted grading tips
Get the most accurate result with these habits.
- Always use your syllabus weight percentages, not your own estimates — even small differences change the final grade.
- If your weights add to more or less than 100%, the tool still works — it calculates proportionally.
- Track your grade mid-semester by entering only completed assignments and their weights so far.
