The Formula

Weighted grade = Σ(score × weight) ÷ Σ(weights)

Understanding the Weighted Grade Calculator: Course & Assignment Weights

Example: homework at 90% weighted 20%, midterms at 80% weighted 30%, and a final at 85% weighted 50% produce 84.50%.

Weights totaling less than 100% are normalized to show the average of entered categories. This is a completed-work average, not a prediction of your final course grade. Totals above 100% are rejected. Set ungraded or unused categories to zero weight.

Partial-work example: homework at 90% with 20% weight and midterms at 80% with 30% weight yield (90 × 20 + 80 × 30) ÷ 50 = 84%. The remaining 50% is not assumed to be zero; this is an average of entered categories. Use the final-exam calculator to explore the missing final.

Frequently Asked Questions

Does my school use the same grading rules?

Check your syllabus or registrar policy. Rounding, extra credit, repeated courses and pass/fail exclusions vary. These results are planning estimates.

Can I leave unused categories blank?

Yes. Set the unused category weight to zero; its score can be blank. A category with positive weight needs a valid score. Do not enter both a category average and its component assignments, which would double-count them.
