Weighted Grade Calculator

Calculate your final grades accurately with this free Weighted Grade Calculator. Enter scores and their respective weights to get your weighted grade instantly.

Weighted Grade Calculator

A weighted grade calculator is a tool to grade a course or assessment based on different weights given to different parts of the course, like quizzes, tests, assignments, and projects. Unlike plain percentage grades, weighted grades take into account the differences in the relative value of the components that contribute to the final mark in a given subject.

Let's say that an exam is given 50% to the final grade, the assignments divide 30,% and quizzes 20%. The weighted grade calculator is unique in the sense that each component in the scale is properly scaled at its weight.

Definition and Formula

To calculate a weighted grade:

\( \text{Final Grade} = \frac{\sum (W_i \times S_i)}{\sum W_i} \)

  • \( W_i \) = Weight of the i-th component (decimal or %)
  • \( S_i \) = Score achieved in the i-th component
  • \( \sum W_i \) = Sum of all weights (usually 1 or 100%)

Understanding the Concept

Weighted grading multiplies each score by its assigned weight and sums them to get the final grade. More important assessments, like final exams, have greater influence than smaller ones, like quizzes.

Example: Assignments = 80% (30% weight), Quizzes = 90% (20% weight), Exams = 85% (50% weight):
\( \text{Final Grade} = (80 \times 0.3) + (90 \times 0.2) + (85 \times 0.5) = 84.5\% \)

Applications

  • Academic grading systems for fair evaluation of course components.
  • Performance reviews to reflect task significance.
  • Course planning and designing grading schemes.
  • Student progress tracking and grade prediction.

Example Calculation

Assignments: 75% (25%), Quizzes: 88% (15%), Midterm: 82% (30%), Final Exam: 90% (30%):

\( \text{Final Grade} = (75 \times 0.25) + (88 \times 0.15) + (82 \times 0.3) + (90 \times 0.3) = 83.55\% \)

How to Use the Weighted Grade Calculator

  1. List all assessments with their scores and weights.
  2. Multiply each score by its weight.
  3. Sum all weighted scores.
  4. Divide by the sum of weights if needed.

Example: Assignments 85% (40%), Quizzes 78% (30%), Exams 92% (30%):
\( \text{Final Grade} = (85 \times 0.4) + (78 \times 0.3) + (92 \times 0.3) = 85\% \)
