How it's calculated
G = (x₁ × x₂ × … × xₙ)^(1/n) = exp( Σ ln xᵢ ÷ n )
Use the geometric mean for quantities that compound, such as average growth over several years: enter growth factors (1.05 for +5%) and subtract 1 from the result. It is always at most the arithmetic mean and needs every value to be positive.
