Average Selling Price _ Now when you calculate your average selling price which is your cost of sales (material + labor) divided by Ƒ_gross profit), you can determine how many customers you would need and then come up with what you think your conversion rate would be for converting leads to customers, you can determine how many leads you would need. Then from this and with the aid of the U.S. Census Bureau and some basic research on your own you can actually have a pretty decent idea of what size your market is and is going to be in the future so you can see if it will support your business plan or not.
So, what would your business look like over the next 10 years to give you that? Could you build a plan that would show exactly how your business could do that? It would show what your sales, fixed expenses, material cost, labor cost, and variable expenses would need to be. It should also show you how many customers you would need and would show you what your profit and profit margins would be each year. All it takes is your current business numbers as we listed earlier and you can make a business plan as many years out as you like.
