Calculate yield percentages, waste factors, and true cost per serving for your recipes. This tool helps commercial kitchens optimize their food production by quantifying the financial impact of yield loss and cooking energy costs.

How It Works

Yield & Waste Calculation:

Yield % = (Cooked Weight ÷ Raw Weight) × 100
Waste % = 100 - Yield %
Cost per Serving = Raw Ingredient Cost ÷ Number of Servings

Energy Cost:

Energy kWh = (Oven Wattage ÷ 1000) × (Cooking Minutes ÷ 60) × Oven Efficiency
Energy Cost = Energy kWh × Electricity Rate
Total Cost per Batch = Raw Ingredient Cost + Energy Cost

Yield & Waste Calculation:

Yield % = (Cooked Weight ÷ Raw Weight) × 100
Waste % = 100 - Yield %
Cost per Serving = Raw Ingredient Cost ÷ Number of Servings

Energy Cost:

Energy kWh = (Oven Wattage ÷ 1000) × (Cooking Minutes ÷ 60) × Oven Efficiency
Energy Cost = Energy kWh × Electricity Rate
Total Cost per Batch = Raw Ingredient Cost + Energy Cost

FAQ

Q: What is a good yield percentage for meat?
A: Beef typically yields 70-80%, poultry 65-75%, and fish 60-70% after cooking and trimming.

Q: How can I improve my food yield?
A: Proper portioning, standardized recipes, staff training, and accurate cooking temperatures all improve yield.

Q: What is the average food waste cost for restaurants?
A: Restaurants typically waste 4-10% of food purchased, representing 2-5% of total revenue.
