The dishes of fast-food box lunch are all common home-cooked dishes, so the required ingredients are also common in the market. According to the observation and analysis of the situation of several fast-food restaurants, the profit rate of a fast food served in 10 yuan is 40%, excluding the cost of materials, labor and various required costs.

Fast food is also economical and very popular with the public, so the sales volume is also very large, with a profit of several hundred yuan a day and thousands or even tens of thousands a month, but after deducting some variable costs, including utilities and packaging fees, the net profit will be low.
