Food Procurement & Cost Control — Page 1 Notes

Learning Objectives

• Explain how cost works in the foodservice industry.

• Describe variable costs and fixed costs.

• Examine controllable and non-controllable costs.

• Identify prime costs.

Chapter Overview: Cost Concepts in Foodservice

• The chapter defines cost as used in the foodservice industry and presents multiple perspectives for viewing costs:

  • Fixed vs. variable costs

  • Controllable vs. noncontrollable costs

  • Total vs. unit costs

  • Historical vs. planned or budgeted costs

• It defines sales and introduces a set of common terms used to discuss and compare sales, including:

  • Total dollar sales

  • Total dollar sales by category

  • Sales price

  • Cover

  • Average number of covers

  • Seat turnover

  • Sales mix

  • Average dollar sale (or average cover)

  • Sales per serving person

  • Sales per seat

  • Quantity of items sold

• The chapter emphasizes the importance of monitoring and evaluating cost and sales data frequently to support decision-making and cost control.

Key Concepts: Cost in Foodservice

• Cost in foodservice reflects resources used to produce and sell food and beverage items.

• Costs can be analyzed from several angles to inform procurement, pricing, budgeting, and performance evaluation.

• Understanding cost structures enables managers to identify where to focus cost control efforts and how changes in volume affect profitability.

Fixed Costs

• Definition: Costs that do not fluctuate with the level of production or sales within a given range of activity.

• Common examples in foodservice:

  • Rent or lease payments

  • Property taxes and insurance

  • Salaries of certain management staff

  • Depreciation on equipment

• Significance:

  • Fixed costs set a baseline that must be covered by contribution from sales; the higher the fixed costs, the higher the sales volume needed to achieve profitability.

• Practical implication:

  • In menu planning and capacity decisions, consider how changes in volume affect the ability to spread fixed costs over more units (economies of scale).

Variable Costs

• Definition: Costs that vary directly with the level of production or sales activity.

• Common examples in foodservice:

  • Food ingredients and beverages

  • Consumables (napkins, straws, packaging)

  • Utilities tied to usage (electricity, gas) that correlate with production volume

  • Wages for hourly staff aligned with hours worked (depending on labor model)

• Significance:

  • Variable costs respond to changes in volume, making them a primary lever for cost control and pricing decisions.

• Practical implication:

  • Controlling portion sizes, yield, and supplier contract terms directly impacts variable costs and overall profitability.

Controllable vs Non-Controllable Costs

• Controllable Costs:

  • Costs that a manager can influence in the short term through decisions and actions (e.g., portion control, supplier changes, menu mix, energy use policies).

• Noncontrollable Costs:

  • Costs largely outside immediate managerial influence during a given period (e.g., base rent under a fixed lease, long-term debt). These may still be influenced indirectly over time.

• Significance:

  • Distinguishing between controllable and noncontrollable costs helps with accountability, performance measurement, and operational decision-making.

• Practical implication:

  • Focus cost-reduction efforts on controllable costs; monitor noncontrollable costs for efficiency opportunities (e.g., renegotiating terms at contract renewal, reallocating resources).

Total vs Unit Costs

• Total Costs:

  • The aggregate cost incurred over a period or for a given output level (e.g., monthly operating costs, total food cost for a shift).

• Unit Costs:

  • Cost per unit of output (e.g., cost per plate, cost per cover, cost per serving).

• Significance:

  • Unit costs enable comparisons across menu items, shifts, or days, and are essential for pricing and menu engineering.

• Practical implication:

  • Track both total and unit costs to gauge overall performance and to identify item-level profitability.

Historical vs Planned (Budgeted) Costs

• Historical Costs:

  • Actual costs incurred in the past (what happened).

• Planned/Budgeted Costs:

  • Forecasted or targeted costs for a period (what we aim to achieve).

• Significance:

  • Variances between historical and budgeted costs reveal efficiency gaps, pricing effectiveness, and the impact of operational changes.

• Practical implication:

  • Use variance analysis to adjust purchasing, staffing, and menu decisions; update forecasts with new data to refine budgeting accuracy.

Sales Terminology and Metrics

• The chapter defines sales using a set of related terms to discuss performance and comparison:

  • Total dollar sales: overall revenue generated from sales.

  • Total dollar sales by category: revenue broken down by categories (e.g., food, beverages, retail items).

  • Sales price: the price charged per item or unit.

  • Cover: a guest served; a single dining guest in a defined period.

  • Average number of covers: average guest count over a period.

  • Seat turnover: rate at which seats are occupied and freed; higher turnover indicates more guests served per seat.

  • Sales mix: the composition of sales across different categories or items.

  • Average dollar sale (or average cover): average revenue per guest or per cover.

  • Sales per serving person: revenue generated per guest served.

  • Sales per seat: revenue generated per seat (often over a period).

  • Quantity of items sold: units sold, useful for inventory and procurement planning.

• Significance:

  • These metrics help evaluate performance, pricing strategies, productivity, and operational efficiency, and support benchmarking against targets or past periods.

• Practical implications:

  • Use sales data to inform menu design, promotions, and procurement decisions; monitor trends to adjust staffing, inventory, and pricing.

Formulas and Key Equations (LaTeX)

• Cost relationships: $TC = FC + VC$

  • Total Cost (TC) equals Fixed Costs (FC) plus Variable Costs (VC).

• Variable costs and output: $TVC = v_u \times Q = \sum<em>i v</em>i \; q_i$

  • If variable cost per unit is $vu$ and quantity is $Q$, then total variable cost is $TVC = vu \cdot Q$; more generally, sum over item-specific variable costs $TVC = \sum<em>i v</em>i q_i$.

• Cost per unit (average cost):
  $C_per_unit = \frac{TC}{Q} = \frac{FC + VC}{Q}$

• Prime costs (typical in cost accounting): $PC = DM + DL$

  • Direct Materials (DM) plus Direct Labor (DL).

• Sales metrics (definitions in formula form):

  • Total dollar sales (aggregate):
    $TDS = \sum<em>i p</em>i \cdot q_i$

  • Average dollar sale (per cover or per guest):
    $ADS = \frac{TDS}{C}\quad\text{where } C = \text{number of covers}$

  • Sales mix by category k:
    $SM<em>k = \frac{TDS</em>k}{TDS}$

  • Seat turnover (per-period):
    $ST = \frac{\text{Covers}}{\text{Seats}}$

  • Sales per serving person (per guest):
    $S_{per_guest} = \frac{TDS}{\text{Servings}}$

  • Sales per seat:
    $S_{per_seat} = \frac{TDS}{\text{Seats}}$

  • Quantity of items sold (units):
    $Q_{sold} = \sum<em>i q</em>i$

• Notes:

  • Symbols are kept generic; adjust to your actual data identifiers in practice.

Examples and Scenarios (illustrative)

• Example 1: Fixed and variable costs for a month

  • Fixed costs (FC): \$50{,}000

  • Variable cost per meal (vc_u): \$5

  • Meals served (Q): 4{,}000

  • Total variable costs: $TVC = vc_u \times Q = 5 \times 4000 = \$20{,}000$

  • Total costs: $TC = FC + VC = 50{,}000 + 20{,}000 = \$70{,}000$

  • Cost per meal: $C_{per_unit} = \frac{TC}{Q} = \frac{70{,}000}{4{,}000} = \$17.50$

• Example 2: Sales and average check

  • Total dollar sales (TDS) for a shift: \$12{,}000

  • Covers (C): 400

  • Average dollar sale per cover: $ADS = \frac{TDS}{C} = \frac{12{,}000}{400} = \$30.00$

• Example 3: Sales mix

  • TDS by category: Food = \$6{,}000, Beverages = \$3{,}500, Other = \$2{,}500

  • Total TDS = \$12{,}000

  • Food mix: $SM_{Food} = \frac{6{,}000}{12{,}000} = 0.50\; (50\%)$

• Example 4: Seat turnover

  • Covers: 900 in a day

  • Seats: 100

  • Seat turnover: $ST = \frac{900}{100} = 9.0 \text{ turns/day/seat}$

Practical Implications and Real-World Relevance

• Monitoring and evaluation:

  • Frequent analysis of cost and sales data allows timely adjustments in purchasing, portion control, pricing, and staffing.

  • Variance analysis (actual vs. budgeted) helps identify where forecasts diverge from reality and why.

• Procurement and menu decisions:

  • Understanding prime costs (DM + DL) and the relationship to sales informs menu engineering and negotiation with suppliers.

  • Aligning menu mix with favorable contribution margins improves overall profitability.

• Operational controls:

  • Control of fixed costs is often achieved through space utilization, equipment efficiency, and staffing models.

  • Reducing controllable variable costs can be achieved via portion control, yield management, energy efficiency, and waste reduction.

• Ethical and practical considerations:

  • Transparent reporting, honest budgeting, and fair pricing practices support long-term sustainability and stakeholder trust.

• Foundational connections:

  • These cost and sales concepts underpin budgeting, pricing strategy, inventory management, and performance measurement across foodservice operations.

Connections to Foundational Principles

• Cost behavior analysis: understanding how costs respond to changes in volume supports break-even analysis and profitability planning.

• Revenue management: sales metrics and mix inform pricing, promotions, and product mix optimization.

• Resource stewardship: balancing cost control with quality and customer satisfaction.

• Decision-making under uncertainty: historical vs budgeted costs provide basis for risk assessment and scenario planning.
