Now let's say next year you want to have a profit margin of 25% so what would your sales need to be to give you that profit margin? Now you might think you would simply tack on 4ǐ% more to sales ྐྵ% _ 20ǒ%) and you would have it. Well not quiet. it doesn't work that way because you are going to have the additional variable expenses, material cost, and labor cost too. Remember, the more sales the more each of these expenses and cost will be. So here is how you would do it: Projected sales = fixed exp (足ꯠ) divided by 1_ƖǑ% + 27ǔ% + 12ǔ% + 25% (your new profit margin) = 造같 (new sales). You can do this for as many years out as you want. Obviously this is based on your first year's fixed expenses remaining constant and no consideration of depreciation, inflation, or taxes.
Variable expenses are those expenses that track directly with sales. If sales stop they stop. These are expenses like supplies used to support in the making of your product or doing your service. Such things as shipping cost for raw materials for your product or service. If you have no sales then you're not going to be purchasing materials so your shipping cost for those materials will stop as well. As an example, if you have a lawn mowing business and there are no lawns to mow, then you wouldn't be buying gasoline to travel to your lawn mowing site. These kinds of things are variable expenses. If you're producing a product, it would include supplies used to produce that product like sand paper, glue, finishing materials, cutting tools, etc.
