The median annual wage of automotive service technicians and mechanics was $35,790 in May 2010. (The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less.) The lowest 10% earned less than $20,200, and the top 10% earned more than $59,590. Many experienced technicians working for automobile dealers and independent repair shops receive a commission related to the labour cost charged to the customer. Under this system, weekly earnings depend on the amount of work completed in addition to a guaranteed minimum salary.
