I mentioned that the 'writing of a business plan' as one of the pivotal steps involved in setting up a successful business. By now you should understand the need for writing a business plan. Writing a business plan, for a traditional brick and mortar business, will probably take a lot of time. It may take up to 100 hours or even more. For obvious reasons, a new business needs to carry out a lot of research before a business plan can even be developed.
Why do you need to know these percentages? As your sales increases or decreases, your material cost, labor cost, and variable expenses will track accordingly. They will track very close to the same % as your current business. As an example, let's say your current sales is averaging 贄ꯠ per month and your material cost is averaging ฤꯠ per month. That's 20% of your sales (ฤꯠ ÷ 贄ꯠ = 20%). So, what would your material cost be if your sales were averaging 赨ꯠ per month? It would still be 20% but it would be 20% of 赨ꯠ or ุꯠ. So with these percentages, you can project your material, labor and variable expenses. See how it works?
