As of 2015, the average cost of starting a food catering truck can vary based on several factors, but a reasonable estimate is between $70,000 and $80,000, according to Forbes. The bulk of the expense is for the truck itself, but numerous other costs factor into the final total.
Prospective food truck owners can find deals on used trucks for less than $10,000, but there may be heavy costs involved with retrofitting the vehicle to be a service-worthy kitchen, PBS Need to Know reports. Additional costs, such as food inventory, employees and permits are added to the cost of the truck itself. Permits and parking fees range in price among different cities, and they can add significant overhead cost in some locations.
