Kitchen Food Waste Loss Formula

Total Waste Cost = Σ(Wasted Quantity × Unit Cost); Annualized Waste = Period Waste × Timeframe Multiplier; Waste % = (Waste / Purchases) × 100
  • Prep Trim: Over-trimming proteins and vegetable skins that could be converted to stocks or sauces.
  • Spoilage: Perishable produce and dairy reaching expiration before service.
  • Burnt / Remade Tickets: Kitchen errors requiring double ingredient usage without additional revenue.
  • Plate Waste: Over-portioning that patrons leave uneaten on plates.
