Food cost percentage
Food cost percentage is the cost of the ingredients you used, divided by the sales those ingredients generated, over a set period.
Food cost percentage answers a plain question: of every dollar a guest spends on a dish, how many cents went to buying the ingredients. You calculate it as cost of goods used divided by food sales for the same window. Across the industry it runs at a median of 32.0% / 32.4% of sales of sales, though the healthy target depends on your format: a pizzeria buying flour and cheese sits very differently from a steakhouse buying center-cut protein. What matters is not hitting a magic number but knowing yours and watching it move.
Two things quietly wreck this number: waste and price creep. Suppliers raise prices between orders and menu prices do not follow, so a recipe that was 28% last quarter is 34% today and nobody noticed. Add trim, spoilage, over-portioning, and comped or remade plates, and the ingredients you paid for never turn into sales at all. Because restaurant menu prices rose +4.1% in 2025 recently, the operators who protect margin are the ones re-costing recipes continuously, not annually.
AI closes both gaps. Invoice-scanning tools flag the moment a vendor's price changes and show which dishes it just made unprofitable, and AI waste tracking has cut kitchen food waste by as much as 50% waste cut and delivered 2-8% food-cost savings in documented food-cost savings. See menu optimization and inventory and food cost for how this connects to repricing and ordering.
