The control cable price formula is as follows: copper weight X copper price calculation: silk ÷ 2 = 1.25X1.25X3.14 = square number X wire number X0.89X copper price + 10% processing fee at that time. Control cable cost price calculation Square X1.83 = weight of copper X copper price at that time + price of armor (weight X 0.4 yuan / kg) = cost price + 10% processing fee Cable price = manufacturing material cost + fixed fee + tax + business fee + profit Manufacturing material cost = material cost * (1 + material consumption) (material cost is the theoretical calculated value) Fixed fees vary according to the circumstances of each company, and generally include production wages, management wages, utilities, repairs, depreciation, rent, and transportation.
