How Weighted Grade Calculation Works

A weighted grade average accounts for the different importance (weight) of each grading category. For example, a final exam worth 40% of your grade carries more weight than homework worth 10%.

Weighted Average = Σ (Score × Weight) / Σ Weight

Letter Grade Scale

This calculator uses a standard letter grade mapping:

  • A+: 90% and above
  • A: 85% – 89%
  • A-: 80% – 84%
  • B+: 75% – 79%
  • B: 70% – 74%
  • B-: 65% – 69%
  • C+: 60% – 64%
  • C: 55% – 59%
  • C-: 50% – 54%
  • D: 40% – 49%
  • F: Below 40%

Tips for Improving Your Grade

Focus on the categories with the highest weight. Even a small improvement on a heavily weighted exam can significantly boost your overall grade. Use the Exam Score Calculator to find out what you need on your final exam.

Each category (assignments, exams, projects) has a weight (e.g., 30%, 50%, 20%). Your grade = Σ(category average × category weight). Weights must total 100%.
