I teach that you should seek to learn from competitors; obviously never copy another business's idea or what they are doing, but you can absolutely learn from their mistakes or see what they are doing and discover ways to improve it. All of that analysis belongs in your business plan: make sure you have your competitors under the microscope and make sure that is a solid chunk of your plan. That is some of the best research and information you will gather about what will make your business successful in future.
So how would you go about calculating all this? There is quite a bit of calculations and you should know a little about business principles but it isn't that complicated. So first let's look at figuring out your future needed sales with this formula: Projected sales = fixed expenses divided by Ƒ_(var exp % of existing sales + mat cost % of existing sales + lab cost % of existing sales + desired net prof %)) So, let's say you existing sales is 迲ꯠ annually, your fixed expenses are 足ꯠ, variable expenses is ็ꯠ or 6Ǒ% of the 迲ꯠ, material cost is 趌ꯠ or 27ǔ%, labor cost is 贍ꯠ or 12ǔ%, and your existing profit margin is 赏ꯠ or 20ǒ%. 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.
