How to Use This Calculator

  1. List each graded item with its percentage score and the weight printed on your syllabus.
  2. Calculate weighted average to see performance across everything entered so far.
  3. Use the target solver with remaining weight (final exam, project, etc.) to gauge what score hits your goal.
📐 Formula

Formula & Methodology

View formula, sources, and explanation+
Weighted average = Σ(score × weight) ÷ Σ(weight) Overall points (weights →100%) = Σ(score × weight ÷ 100) Needed remaining score x: x = (target − earned_points) ÷ (remaining_weight ÷ 100)

Scores are treated as percentages. If your instructor drops grades or curves, adjust manually.

❓ FAQ

Grade FAQ

  • They should match your syllabus; the calculator sums entered weights for averages and highlights when they diverge from 100%.
  • Each score contributes score × weight. We divide by the sum of weights you entered so partial syllabi still make sense.
  • It assumes one remaining bucket with the weight you enter and solves for the score that reaches your target overall percentage.
  • This tool expects percentage scores (0–100). Convert points to percents before typing them in.
  • Treat extra credit as another row or adjust weights manually—talk with your instructor when weights exceed 100%.
