Finance and Business Management: Ratios, Margins, and Break-Even
Know your numbers cold
Catering finance centers on the profit and loss statement and three ratios: food cost percentage, labor cost percentage (including burden - payroll taxes, benefits, workers' comp), and prime cost (food + labor, commonly targeted at 60–65% of revenue). Also understand fixed versus variable costs, contribution margin, break-even, budget variance, cash flow, and internal controls such as purchase orders, receiving checks, and inventory counts.
Traps: confusing markup with margin. A 30% markup on a $10 cost yields $13.00; a 30% food cost target on the same item yields $10 ÷ 0.30 = $33.33. Another trap is computing food cost percentage against cost rather than selling price, or forgetting that break-even divides fixed costs by contribution margin per cover - not by total cost.
Worked example. Fixed costs are $120,000 per year; average revenue per cover is $65; variable cost per cover is $42. Contribution margin is $23. Break-even = $120,000 ÷ $23 ≈ 5,217 covers per year, about 100 per week. Raising the average check to $71.50 lifts contribution margin to $29.50 and drops break-even to roughly 4,068 covers.
Rule of thumb: price = plate cost ÷ target food cost %. A $4.20 plate at a 28% target prices at $15.00.
