# Weighted Average Calculator

This weighted average calculator calculates your average of all your courses. The weighted average simply takes into account how much each course is worth when calculating the average. This calculator can also be used to calculate any weighted average, not just courses.

Average Grade of All Courses

## Important Notes

Although our weighted average calculator is often used to calculate overall semester average grades for courses that have varying weight in terms of credits, the actual calculation that we use can be applied to any group of numbers, regardless whether they are weighted differently or not. This means that you can calculate the weighted average of your assignments, courses, or even different semester years. Furthermore, our weighted average calculator can be used to calculate a simple unweighted average. This is because the basic average of a group of numbers is the same calculation as a weighted average except that the weights of all the numbers are calculated as being the same. Thus to calculate the basic average of any group of numbers using our calculator, all that needs to be done is setting the weights of all the courses to be the same value, for example set them equal to 1.

## How does it work?

The calculations behind our weighted average calculator are quite simple. Instead of just summing up all the grades and then dividing them by the total number of grades (which would get the basic average), each grade is multiplied by weight and then summed up and this time divided by the total weight or credits, as explained below:

- Basic Average = (Grade1 + Grade2 + ... + ...) / (Total number of grades)
- Weighted Average = ( Grade1 * Weight1 + Grade2 * Weight2 + ... + ...) / (Weight1 + Weight2 + ... + ...)
