7 Total Costs and Unit Costs Unit Cost (or Average Cost) Total cost / some number of units Average cost = Total manufacturing costs / Number of units produced = $980,000 / 10,000 = $98 per unit Unit or average costs must be interpreted with caution As volume increases, the unit or average cost falls as the fixed costs are spread over a larger number of units Copyright 2003 Pearson Education Canada Inc.
