Free food-waste & margin-recovery tool
Restaurant Food Waste Cost Calculator
Turn spoilage, prep waste, overportioning and finished-food discard into monthly food-cost leakage, annual lost margin and a practical waste-reduction ROI case.

Lost-margin logicNet avoidable food waste is treated as direct ingredient-cost leakage. If sales remain unchanged, each avoidable dollar recovered increases gross contribution by roughly one dollar. This is not restaurant net profit.

10 food categories
Advanced category logicEach category has separate purchase dollars, spoilage, prep waste, overportioning, finished-food discard and salvage/recovery. This lets high-cost categories rise to the top even when their waste percentage is lower.

Scope
Waste cost is ingredient-cost leakage, not full restaurant net profit
This tool estimates avoidable food-cost leakage. It does not assign rent, front-of-house labor, management, utilities, taxes or other restaurant overhead to waste. Waste categories can overlap if the entered percentages are not measured consistently, so use one definition per source and reconcile the totals against purchasing and inventory data.
