The "Average Calculator" is a tool that allows users to calculate the average or arithmetic mean of a set of numerical values. The tool typically has a simple interface where users can input the values that they want to calculate the average of. Once the values are entered, the tool computes the sum of the values and divides it by the total number of values to provide the average.

Some average calculators may also include additional features such as the ability to exclude certain values or to calculate the weighted average based on specific weights assigned to each value.

The average calculator is commonly used in various fields such as finance, science, and education to quickly and accurately calculate the average of a dataset. It can be especially helpful for individuals who need to analyze data and make informed decisions based on numerical values.
