Average Calculator
Calculate the arithmetic mean, median, geometric mean, sum, count, min, and max of any set of numbers. Free online average calculator with charts and statistics.
About This Calculator
The Average Calculator computes the arithmetic mean, median, geometric mean, sum, count, minimum, and maximum of any set of numbers. Whether you're a student analyzing test scores, a data analyst exploring dataset statistics, or a professional calculating performance metrics, this tool provides all the key measures of central tendency in one place.
The arithmetic mean (average) is calculated by summing all values and dividing by the count. The median finds the middle value when numbers are sorted, making it robust against outliers. The geometric mean, computed as the nth root of the product of n values, is ideal for growth rates and ratio-based data. Together, these statistics give you a comprehensive understanding of your data's distribution.

Frequently Asked Questions
How do you calculate the average of a set of numbers?
To calculate the arithmetic mean (average), add all the numbers together and divide by the count of numbers. For example, for the numbers 10, 20, 30, 40, and 50: sum = 150, count = 5, average = 150 / 5 = 30. Our calculator also computes the median, geometric mean, sum, minimum, and maximum automatically.
What is the difference between mean, median, and geometric mean?
The arithmetic mean is the sum divided by the count of numbers. The median is the middle value when numbers are sorted in ascending order — it is less affected by outliers. The geometric mean is the nth root of the product of n numbers and is useful for rates of change and percentages. Each measure gives a different perspective on the central tendency of your data.
When should I use median instead of mean?
Use the median when your data contains extreme outliers or is heavily skewed. For example, in income data where a few very high earners can distort the mean, the median better represents a typical value. The mean is best when data is symmetrically distributed without outliers.
Can the average calculator handle decimal numbers?
Yes, the average calculator supports decimals, negative numbers, and large datasets. Enter numbers separated by commas or spaces, and the calculator will display results rounded to two decimal places. The breakdown table shows all computed metrics with full precision.
What is the geometric mean used for?
The geometric mean is commonly used in finance to calculate average rates of return over time, in biology to measure population growth rates, and in geometry for proportional scaling. Unlike the arithmetic mean, it handles multiplicative relationships correctly and is always less than or equal to the arithmetic mean for positive numbers.
Is this average calculator free to use?
Yes, the average calculator is completely free to use with no registration or download required. You can share your calculation by copying the URL, which saves all your input values.
How many numbers can I enter at once?
You can enter as many numbers as you like, limited only by your browser. Simply separate each number with a comma or space. The calculator instantly processes your entire dataset and displays the mean, median, geometric mean, sum, count, minimum, and maximum.
