Certainly, most restaurants use food cost as a % of sales as a key performance indicator. This week, an anonymous reader asked about tracking food cost in a different environment - a health care facility. He asked if it was advisable to use cost per patient per day in lieu of a percentage. I strongly recommend using the cost per patient day over a percentage benchmark.
In the remote site feeding segment, we tracked all costs per person per day. The advantages to management are greater in labor cost analysis using this method. Food cost generally is variable while labor has both a fixed and a variable component. With long term sales prospects dampened by the recession, tight control has helped many companies survive and prosper.
Is it possible to effectively use per cover cost analysis in a restaurant environment? Many chefs prefer to track menu item performance using gross margin per plate. Since the aim is to make more dollars vs. a higher percentage, they need to take care when analyzing other costs. Direct labor, direct operating expenses and overhead costs should follow suit. If the operation sells higher priced items with relatively high food cost %, the use of cost per cover for non-food expenses is necessary.
