HVAC business, the overhead is higher than a juice business but it lay's out what overhead does to the cost of a product or service.
Homeowner could buy a fan motor for their AC for $150. Install it themselves and all it cost them was the $150 and their time. The same motor cost me $80. I have to pay an employee to go to your house and replace motor. He makes $35 per hour and it took 2 hours to complete. It doesn't end there. I have to pay an accountant, rent on the building, utilities, insurance on the business, insurance for my employee, insurance on the van, maintenance on the van, and gas for the van, and the website. You wouldn't believe the taxes that have to be paid. I have to pay taxes on the business income, my income I even have to match my employee's taxes!! In the end I have to charge the customer $650.00 so the company can profit about $50. I still haven't been payed !!!!!
