You have to calculate the cost, 50 thousand+monthly operating cost (including material cost and labor cost), and how long it will take to rent a store. If the monthly operating cost is 3,000 yuan and the lease term is 2 years, the total operating cost is 72,000 yuan, plus the investment cost, one * * * is 122000. Excluding the four months of winter and summer vacation, the actual operation time in these two years is 65438. You have to earn 7625 yuan a month to get your money back, and you earn more than that. Now these are hypothetical data, and you can calculate them according to your actual situation. If a cup of milk tea is sold in 20 yuan, the net profit is 15 yuan. You can calculate how much milk tea you want to sell a month to reach this figure, and then estimate whether the consumption of these 600 people can reach the sales quantity. These are the accounting ideas I gave you. You should adjust the data calculation results according to the actual situation. If you want to operate, you must know the cost clearly and evaluate the cost conversion result clearly, so that you can be sure of the future income. If you estimate the possibility, you won't succeed without clear data support.
