2. Profit calculation formula: profit = selling price-purchase price. Calculation formula of profit rate: profit rate = profit/purchase price × 100%.

3. For example, if a commodity is purchased in 30 yuan and sold in 50 yuan, what is the profit? According to the meaning of the question, the purchase price =30 yuan, and the selling price =50 yuan. Can be calculated according to the profit formula. Profit of a commodity = selling price-buying price =50-30=20 yuan. According to the calculation formula, the profit rate of a commodity = profit/purchase price ×100% = 20/30×100% = 66.67%.

How to set the most appropriate profit in business?

1. The general net profit is 10%-25%. It depends on the cost of your company. If the company has just been established, the business is unstable at this time and the initial investment is relatively large. If it is a loss of about one year, the general situation is normal, and the profit will definitely increase gradually in the later period.

2. If you do, spread the business:

(1). It is aimed at low-end customers, but not after-sales, so the retail price of the stall should not be too high.

(2) There is no need to consider issues such as rent and business tax, and the operating cost is greatly reduced.

(3) However, we should consider the purchase price and the competition with other manufacturers. On the whole, the profit of the stall business should not exceed 50% of the purchase price.

3. It depends on production or sales:

(1) yield: directly related to yield. This is the main influencing factor. Although there is a certain relationship between flour and auxiliary materials, it is not the most important factor affecting profits. If the daily output exceeds 10,000 yuan, even if there is only a little profit for each piece of clothing, your profit will be considerable. Otherwise, this is small profits but quick turnover, which often brings more income.

(2) Sales volume: The most important thing is sales volume. Profit cannot be emphasized by percentage, but depends on the smoothness and quantity in actual operation. When receiving orders, there is often a term called "Taiwan Province output", which determines the level of "profit". Of course, the non-performing rate is also very important.
