Food Waste Cost Calculator
Quantify financial losses from prep trim scrap, expired spoilage, burnt kitchen remakes, and plate scrapings, and project savings from waste reduction.
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.
