Geometric Mean
Average positive multiplicative values using logarithms.
Your numbers
Geometric mean
Use consistent units. The result follows the assumptions you enter.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use G = exp[Σln(xᵢ)/n]. xᵢ are positive observations, n is their count, ln is natural logarithm, and exp is its inverse. Geometric mean G has the observations' unit.

Scope and limitations
Use consistent units. The result follows the assumptions you enter.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
