How it works

For positive values x₁, x₂, ..., xₙ, the geometric mean is:
(x₁ × x₂ × ... × xₙ)^(1/n)

Examples

  • 2, 8 → geometric mean = 4
  • 2, 8, 4 → geometric mean = 4
  • 1.5, 3, 6 → useful for multiplicative scaling comparisons

FAQ

  • What is the geometric mean?

    The geometric mean of positive numbers is the nth root of their product, where n is the number of values.

  • Why do inputs need to be positive?

    This real-number geometric mean tool requires positive values so the nth root of the product is well-defined in the standard way.

  • When is geometric mean useful?

    It is useful for growth rates, ratios, percentages, finance-like compounding contexts, and multiplicative data.

  • Are calculations stored?

    No. Everything runs locally in your browser.
