For jadeite, the purchase cost is shared according to the quality of the goods. The goods at your price are all-inclusive and low-priced, and you can simply divide them into several price bands. There are dozens of dollars in 50 yuan, dozens of dollars in 100, and dozens of dollars in 300 yuan. Calculate the cost like this until you share your purchase cost, and then increase the price according to the quality of each piece of jade and mark it as the sales price, so that each piece has a purchase cost and a sales price, which I usually do. The total sales price of the final bid price should be about 4 times of the purchase price, not less than 3.5, generally not more than 6. If it is too low, the backlog may not be collected when it cannot be sold. As for the problem that the same product has different purchase prices due to different purchase times, generally speaking, jade products are on the rise in recent years if the purchase price gap is not big. If the increase is within 10% and the sales price remains unchanged, which is equivalent to a loss of 10% profit, then the retail profit rate may be too high; If it exceeds 10%, all goods will change their prices, which is the trend of market price increase; However, there are exceptions, such as some models that are not often sold. Generally speaking, as long as the purchase price is not outrageous, it will not change the price of jewelry, especially jade. Prices are rising rapidly, so the calculation of product cost and profit needs to be flexible. All the above are personal experiences for reference only.
