Understanding and Calculating Food Cost Percentage
The Food Cost Percentage is a critical Key Performance Indicator (KPI) for any food service business, including restaurants, cafes, catering services, and bars. It measures the direct cost of the ingredients used to produce the food sold, relative to the revenue generated from selling that food. A lower food cost percentage generally indicates better efficiency in purchasing, preparation, and waste management.
The Formula:
The calculation is straightforward. It involves dividing the total cost of food sold by the total revenue generated from food sales. The result is then multiplied by 100 to express it as a percentage.
Total Food Revenue: This is the total amount of money received from selling food items over a specific period (e.g., a day, week, or month). This should exclude revenue from beverages, service charges, or other non-food items.
Total Food Cost: This represents the actual cost of all food ingredients that were used and sold during the same period. It's not just the cost of inventory purchased but the cost of the ingredients that went into the dishes served to customers. Accurately calculating this often involves tracking inventory usage or using prime costing methods.

Why is Food Cost Percentage Important?
Monitoring your food cost percentage allows you to:
Control Expenses: Identify if ingredient costs are too high relative to sales.
Optimize Pricing: Ensure your menu prices are profitable.
Manage Inventory: Detect potential issues with over-ordering, spoilage, or theft.
Improve Menu Engineering: Understand which dishes are most profitable and which might need adjustments.
Benchmark Performance: Compare your performance against industry averages or your own historical data.
A common target for food cost percentage in restaurants is between 28% and 35%, but this can vary significantly based on cuisine type, business model, and location. Regularly calculating and analyzing this metric is fundamental to the financial health and success of any food business.
