How to calculate the weighted average of grades?

To calculate the weighted average of grades, you need the values of individual grades and their corresponding weights. At school, this is the weight of your tests. At university, these are your study credits (ECTS). Use our calculator or follow these steps:

  1. 1. Make sure you have the values and corresponding weights for each grade.
  2. 2. Multiply each grade by its weight.
  3. 3. Add up all the products.
  4. 4. Add up all the weights.
  5. 5. Divide the sum of products by the sum of weights.

The formula for weighted average of grades

Weighted average = (grade1 × weight1 + grade2 × weight2 + ... + gradeN × weightN) / (weight1 + weight2 + ... + weightN). Where grade1, grade2 ... gradeN are the individual grades, weight1, weight2 ... weightN are the corresponding weights, and N is the number of grades and weights.
