How it works
- The FL ratio is calculated as (food cost F + labor cost L) ÷ sales × 100. It shows the share of sales taken up by food and labor and is a core cost metric in restaurant management.
- The F ratio is food cost ÷ sales and the L ratio is labor cost ÷ sales. The FL ratio equals the sum of these two, letting you see which cost weighs more heavily.
- An FL ratio of 60% or less is generally considered a healthy benchmark, and this tool uses that threshold for its assessment. The remaining roughly 40% covers rent, utilities, and other overhead while securing profit.
- For a more realistic ratio, enter the cost of purchased food and drinks for food cost, and salaries, hourly wages, and social insurance for labor cost.
- Enter sales, costs, and labor for the same period (monthly, daily, etc.). Mismatched periods will produce an incorrect ratio.
- This tool provides a quick estimate only. Base actual profit-and-loss decisions and cost management on your store's real figures and advice from professionals such as a tax accountant.
