Full cost pricing
The practice of setting prices so as to cover what average cost would be at a normal rate of production, plus a conventional mark-up. At times when output is low, actual average costs exceed those when output is normal, as fixed costs have to be spread over a lower output level. One argument for full cost pricing is that firms firequently have to quote a price for much of their output before they know what total output is going to be, and before they know some of their costs. Under these conditions full cost pricing eliminates some of the risk of pricing below cost.
