Formula & How It's Calculated

Current Grade = Σ(Score × Weight) / Σ(Weights) Final Score Needed = (Desired − Current × (100% − Final Weight%)) / Final Weight%

Example Calculations

Homework 88% (20wt) + Midterm 82% (30wt) + Quizzes 91% (20wt)

Current grade: (88×20+82×30+91×20)/(20+30+20) = 5,960/70 = 85.1% (B)

To get 90% overall with 30% final: need (90−85.1×0.70)/0.30 = 101% on final

How It Works

  1. Add your assignment categories — name, score %, and weight %.
  2. Weights should sum to 100% (including final exam weight).
  3. Calculator computes weighted average for current grade.
  4. Enter final exam weight and desired overall grade.
  5. Calculator shows exactly what score you need on the final.
  6. Add or remove rows dynamically.

Grade Calculator – Know Your Grade Before the Final

Our grade calculator computes your current weighted grade average and tells you exactly what score you need on your final exam to reach your target grade. Perfect for mid-semester planning.

Weighted vs Unweighted Grade Averages

A simple average treats all assignments equally. A weighted average gives more impact to high-weight items. If your tests are 60% of your grade and you score 95% on tests but only 70% on homework (40%), your grade is 0.6×95 + 0.4×70 = 85%, not the simple average of 82.5%.
