First, read the English article below.

Figure out how much your store will cost to run before opening it. If you don’t have a full financial picture, your store is unlikely to succeed. Operating costs, sometimes called overhead or fixed costs, are the expenses you have to pay regularly just to keep the store open. Add up all the costs that remain consistent each month and have to be paid. The resulting sum is your operating cost.  Common items for operating costs are rent, utilities, insurance, and phone/internet connections. If you take out loans, paying them back is also a fixed cost. Common advice is to keep your rent about 6% of your yearly sales. Keep this in mind when you add up your costs. If rent is $2,000 per month, that's $24,000 per year. That means you'd need about $400,000 in sales to meet this recommendation. If you can't project sales that high, consider finding cheaper rent. These costs are called variable costs, because they can change from month to month. For instance, you could buy less inventory or hire less workers and your store would still stay open. Add up what all your inventory will cost you and how much paying your employees will cost. Then combine this number with any other variable costs you have.  Some other variable costs include advertising and marketing expenses, since you technically don’t have to do these things to stay open. Add up your fixed and variable costs to get your breakeven price, meaning the amount you have to make each month just to cover your expenses. A business plan is crucial not only to focus your own thoughts, but also because any potential investors will want to see your plan before providing any financing. Put together a comprehensive explanation for your business, including the products you’ll sell, your operating plan, and all your expenses. Be ready to present this plan to anyone you ask for financing.  Start by describing your business concisely. What will you sell and who is your target audience? Then outline how you will fit into the current market. Explain the research that you’ve done...
