What this means Our calculation
Pay for diesel mechanics here is above average compared with other U.S. metros, and in the top 20% once local prices are factored in. For the wider job market, unemployment is higher than in most metros (4.8%) and the population is shrinking (-1.3% since 2020). On your own, you'd join about 138 one-person auto repair businesses averaging $49,761 in revenue, and you'd need to bill roughly $78/hour to match the median salary (at our default assumptions).

Employee vs. working for yourself Your scenario
A model, not a market rate. It shows the minimum you'd need to bill to match a $63,850 employee salary once you cover what an employer normally pays for. Change any number.
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.
