The average cost of general liability insurance in Wyoming runs $106 monthly ($1,269 annually) for businesses with one to four employees with limits of $1 million per occurrence/$2 million aggregate, 14% below the monthly national average of $123. Wyoming ranks 18th nationally, placing it in the more affordable third of all states.
Within the Mountain West, Wyoming sits in the lower-middle tier of a market that ranges from $95 per month (Montana) to $146 (Colorado), a $51 spread across seven states. Wyoming's position near the affordable end likely reflects its relatively lower litigation activity and business density compared to higher-cost neighbors. Colorado is the clearest illustration of how those dynamics shift: at $146 per month and ranking 41st nationally, it runs nearly 38% above Wyoming, reflecting a larger commercial market and higher claims exposure.
Wyoming's figure is a state average, not a rate prediction. More than knowing how near or far you are from it, a more valuable insight is understanding what drives your cost higher or lower.
