Labor and material costs are also directly proportionate to sales. These are things that go directly into the making of the product or into doing the service. a. Labor cost is the actual direct labor used in the making of product or doing the service. The cost would also include all the fringe benefits like social security, payroll taxes, vacation pay, holidays, sick pay days, etc. b. Material costs are all the materials used in the making of product or in doing the service. In the lawn mower service as an example it would be the gasoline used in the mower and any other materials used directly in that service. For producing a product it would be all the materials used in the product that is sent to the customer including all the packaging materials.
If you said the profit margin would be higher, then you are right. Why would your profit be higher? If you said because of the fixed expenses, you would be right. Your material cost, labor cost, and variable expenses would have gone up 10% but your fixed expenses would have remained the same. You brought in more revenue because of more sales and you spent 10 % more on material, labor, and variable expense to cover the extra sales, but you didn't spend any more on your fixed expenses. So, less overall expenses, would give you higher profit margin. Make sense? So, let's see how we would make a business plan that would show exactly how your business could give you the salary you want.
