Breakfast stores have a low cost per item and relatively large profit margins. Assuming that the per capita consumption of a breakfast is around 6 yuan and the cost is about 2 yuan, then the profit per breakfast is about 4 yuan. If you can receive 100 guests a day, the turnover is exactly close to 400 yuan.

But the actual profit and loss is subject to the deduction of other fixed and variable costs, such as rent, staff wages, utilities, raw material purchases and so on. If these costs add up to less than $200, then even with a daily turnover of only $400, the breakfast store is still likely to remain profitable.
