With this information you can actually predict not only what your sales will be, but you can see how much your fixed and variable expenses will be, what your labor cost will be, your material cost, and your profit. So let's first look at what exactly are fixed expenses? They are exactly what they say they are; they are fixed. This simply means these are expenses that are ongoing whether you have a lot of sales or Ŕ" sales. They are expenses like utilities, taxes, rent, salaries other than the wages used in the making of the actual product or doing a service, business fees, telephone, etc. See how these expenses would continue on even if you have 0 sales? Any expenses that fall into this category are fixed expenses. Far too many small business owners never divide their expenses into fixed and variable. As a matter of fact, if you could have a business that had Ŕ" fixed expenses; this would be the best of all worlds, why? If you had Ŕ" sales, you would have Ŕ" expenses. So the closer you could get to this the better you would be.
Remember the proverbial expression 'not seeing the wood for the trees'? You need to see the 'wood' first, then delve in and start examining the individual 'trees', meaning the individual items which you will be breaking down later. So a great point is to make sure that you have that overarching vision _ and if you cannot find one, then maybe it is an indication that you are obsessing on a few technical aspects that do not necessarily make up a whole business as you had imagined it. A business that makes sense and is going to be sustainable in the future is one that has that clear vision within which all the smaller parts contribute to make it successful.
