How it works
Compute exp(mean(ln(value))) for positive observations. Logarithms reduce overflow from multiplying many values.

Common questions
Can I enter percentage growth rates directly?
Convert each percentage return to a gross factor first, such as 1.10 for +10%. Subtract one from the geometric mean of factors to recover a growth rate.
How does Geometric mean work?
Compute exp(mean(ln(value))) for positive observations. Logarithms reduce overflow from multiplying many values.
What should I check before using Geometric mean?
Uses the units and scope stated in the input labels. Results are rounded for display; verify the model is appropriate for your situation.
