What this means Our calculation
Pay for insulation installers here is in the top 20% of U.S. metros, and also in the top 20% once local prices are factored in. For the wider job market, unemployment is about the same as in most metros (4.0%) and the population is shrinking (-0.2% since 2020). On your own, you'd join about 159 one-person building equipment installation businesses averaging $96,409 in revenue, and you'd need to bill roughly $74/hour to match the median salary (at our default assumptions).

Minimum billing rate
How this calculator works. Billable hours are hours you can charge a customer. Driving, quoting, paperwork and slow weeks aren't billable, which is why 1,400 is a common starting point versus 2,080 paid hours as an employee.
