⚠ Input Costs Are Ultimately ExogenousModerate threat

Purchasing scale lowers McDonald's input costs relative to competitors, but it cannot insulate the company from the absolute level of commodity and labor inflation, which is set by forces beyond any single buyer's control. When beef, chicken, dairy, grains, packaging, or energy prices rise sharply, McDonald's pays more too — just less than a smaller rival would — and a period of broad food-cost inflation squeezes the whole system's margins. Labor is an even harder pressure: rising minimum wages and tight labor markets raise costs across tens of thousands of restaurants, and much of that burden falls on franchisees whose margins are already thin.

The bind is that input-cost inflation collides with McDonald's value positioning: raising menu prices to offset higher costs risks driving away the budget-conscious customers who are the core of the value proposition, while absorbing the costs squeezes margins. The company has navigated waves of inflation before, using its scale, menu engineering, and pricing discipline, and its relative cost advantage is real and durable. But scale is a relative advantage, not an absolute shield: when the costs of food and labor rise across the industry, McDonald's is pressured too, and the tension between covering those costs and protecting its value appeal is one of the recurring challenges of the business — sharpest, as now, when the consumer is already stretched and U.S. comps run +0.8%¹.
