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 writing a business plan you sometimes end up locking yourself away. You might have unique ideas which lead you to seek some isolation and secrecy, or if you are going to be a sole trader you may only have one person to consult namely yourself. But it is fantastic to try and get broader input on your business plan _ whether from a professional, or simply from friends and family whom you trust. I say that because of course you need to be careful with commercially sensitive ideas, as you do not want to pass your plan on to someone in the pub who then starts your idea before you across the road.
