Daily Waste Cost
It is how much money you throw in the trash each day from spoilage, over-prep, and plate waste.
Formal definition
Daily waste cost equals the number of wasted or spoiled items per day multiplied by average item cost.
Why it matters
Waste is pure margin loss — it hits food cost without generating a single sale.
Where you see it
- Kitchen waste logs
- Restaurant food-cost audits
- ServSafe and culinary training
- Inventory management systems
- Prime cost troubleshooting
Worked example
- Daily waste items: 18.
- Average item cost: $4.50.
- Daily waste cost = 18 × $4.50 = $81.
- Interpretation: $81 of food cost leaves as waste each day.
How Business metrics calculates it
Daily wasted items × Average item cost (defaults to $4.50 if you leave cost blank).
Where people fool themselves
Waste cost using $4.50 default item cost when you run a steakhouse will understate the bin. Put a real average item cost in the Tier 3 field.
