# HARMEAN function: Description, Usage, Syntax, Examples and Explanation

## What is HARMEAN function in Excel?

## Syntax of HARMEAN function

HARMEAN(number1, [number2], …)

The HARMEAN function syntax has the following arguments:

- Number1, number2, … Number1 is required, subsequent numbers are optional. 1 to 255 arguments for which you want to calculate the mean. You can also use a single array or a reference to an array instead of arguments separated by commas.

## HARMEAN formula explanation

- The harmonic mean is always less than the geometric mean, which is always less than the arithmetic mean.
- Arguments can either be numbers or names, arrays, or references that contain numbers.
- Logical values and text representations of numbers that you type directly into the list of arguments are counted.
- If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.
- Arguments that are error values or text that cannot be translated into numbers cause errors.
- If any data point ≤ 0, HARMEAN returns the #NUM! error value.
- The equation for the harmonic mean is:
