3. 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.
But most likely you would need to increase your fixed expenses because you're going to probably have more rent, utilities, or such as your business grows. So, you would simple put in your new fixed expense number in place of the existing one for each of the years you would be planning for. So, you see if you decided you wanted a 35% profit margin at year 5 then you could see how much sales it would take to give you that. Now it's also important to know how many more customers you would need as well so you should always look at that unless you have another way of growing your sales other than with new customers.
