A percentile shows where pay falls: the 10th percentile means 10% earn less. BLS publishes hourly and yearly figures; yearly assumes 2,080 paid hours (40 hours times 52 weeks). $115.00+ means BLS reports it only as at least that amount.
What affects insulation pay in Montana
- Metro area. Billings, MT pays a median of $24.14 an hour, 4% above the Montana median.
- Experience and skill. In Montana, the top 10% earn at least $40.07 an hour, while the bottom 10% earn $17.79 or less. That gap of $22.28 an hour reflects experience, specialty and responsibility.
- State market. The Montana median is 2% below the national median of $23.62 for Insulation Workers, Floor, Ceiling, and Wall.
- Overtime. BLS figures are straight time pay. Overtime, shift pay and bonuses are not included, so total earnings can be higher.
