Geometric Mean Calculator

This geometric mean calculator helps when value 1, value 2, value 3 are already known and you want the geometric mean quickly.

Important Use Notice

Informational calculator only. Verify important outputs independently before legal, tax, medical, engineering, safety-critical, contractual, employment, or compliance use.

Estimate

Enter job values, review the estimate, then use the decision hints before ordering or quoting.

Estimate Results

Enter values to see the result.

Example

4, 9, 16 gives Geometric Mean 8. 32.

Formula

geometric mean = (value1 x value2 x value3)^(1/3)

Multiply the values together and take the cube root for a three-value geometric mean.

All three inputs should be non-negative for this simplified page.

Check

Mixing units or scales across value 1, value 2, value 3 before calculating geometric mean.
Confirm that all inputs use the same unit system expected by the formula.
