Weighted Grade Calculation Formula and Example

Percent Weights Formula

If your assessments use percent weights, the weighted grade is:

Weighted Grade (%) = Σ(weight% × score%) ÷ Σ(weights%)

Example

Suppose you have:

Weighted Grade = (20×95 + 30×88 + 50×84) ÷ (20+30+50) = (1900 + 2640 + 4200) ÷ 100 = 87.40%

  • Homework: weight 20%, score 95%
  • Quizzes: weight 30%, score 88%
  • Final Exam: weight 50%, score 84%

Points Mode Formula

If your course uses points, the overall percent is:

Overall (%) = (Total Earned ÷ Total Possible) × 100
