How to use this tool?
This calculator computes the Geometric Mean of a set of positive numbers. The geometric mean is the nth root of the product of n numbers, useful for averaging rates, ratios, or growth factors.
- Enter numbers in the text area. Separate them by commas, spaces, or new lines. Example:
2, 4, 8or1.5 3 6. - Only positive numbers are allowed (greater than zero). Negative numbers or zero will show an error.
- Click "Calculate Geometric Mean" or press Shift+Enter while in the text area.
- The result appears below with the value rounded to 4 decimal places. Steps show the count (n), product, and final mean.
Tip: Use this for growth rates, investment returns, or any multiplicative data. The geometric mean is always less than or equal to the arithmetic mean.
