Grade Calculator
Calculate your weighted average grade for any class. Enter up to three assignment grades with their respective weights, and this calculator will compute your overall weighted average, letter grade, and GPA equivalent on a 4.0 scale.
Weighted averages ensure that more important assignments (like finals) count more toward your grade:
Weighted Average = Sum of (Grade x Weight) / Total Weight
For example, if homework (30%) is 90%, midterm (30%) is 85%, and final (40%) is 78%, your weighted average is (90x30 + 85x30 + 78x40) / 100 = 83.7%, which is a B.
Make sure your weights add up to 100% for accurate results. If they don't, the calculator normalizes them proportionally.
