In retail, unit price is the price for a single unit of measure of a product sold in more or less than the single unit. The unit price tells you the cost per pound, quart, or other unit of weight or volume of a food package. It is usually posted on the shelf below the food.
Fixed Cost per Unit at 3,000 units. The fixed costs remain at Â£120,000 and the fixed cost per unit = 120,000 / 3,000 = Â£40 per unit. The total cost of a unit at this level of activity is Â£86 + Â£40 = Â£126. Operating at a markup on cost of 40% the selling price would need to be Â£126 x 140% = Â£176.40.
