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.
When you, and your partners if any, have all the core skills and industry knowledge you need to start right away without seeking experts, napkin notes may be enough to get going. Let's say you are already an expert in technology and social media. Then you, and your team, probably don't need a detailed plan to start developing a new app. You will draw on your knowledge and experience, and you understand that you might need to go back and do some more detailed and formal planning later. Certainly when you reach the point where you are looking for investors or lenders, you will move beyond those first casual notes. Until then, drawing upon your expertise can allow you to quickly jump into the market and perhaps gain a competitive edge by using a minimalist plan.
