Let me tell you about the calculation of the labor cost of my jewelry store for reference only. It belongs to those with shopping receipts.
According to the calculation of your goods: 2.62*35 (labor cost) =92 yuan (9 1.7), and the other 2.62* 10 (price difference per gram) =26 yuan, excluding 2.62 grams, which is calculated according to the actual sales price.
Also, generally speaking, processing fees don't earn much money. I want to know how much a gram of platinum is now loaded, but I can't sell it with old materials. Where is his cost?
