Average Calculator

How this average calculator works

Enter a list of numbers separated by commas, spaces, or new lines. The calculator computes the mean (arithmetic average), median (middle value), sum, and count.

Mean vs Median

The mean is the sum divided by the count. The median is the middle value when sorted — if there are an even number of values, it's the average of the two middle values. Use the median when your data has outliers (e.g., incomes, home prices) because a few extreme values can skew the mean.

Formulas

• Mean = Sum of all values ÷ Number of values
• Median = Middle value (or average of two middle values)
