This guide explains what prime costs are, how to calculate them, industry benchmarks, common mistakes, and practical strategies for reducing costs without sacrificing quality or customer experience.

What Are Prime Costs in a Restaurant?

Prime costs are the combined total of a restaurant's cost of goods sold (COGS) and labor costs.

These two categories usually represent the largest operating expenses for most restaurants.

Prime costs include:

Cost of Goods Sold (COGS)

• Food ingredients
• Beverages
• Condiments
• Packaging for takeout
• Disposable serving items

Labor Costs

• Employee wages
• Salaries
• Payroll taxes
• Overtime
• Employee benefits
• Paid time off

Why Prime Costs Matter

• Improve profitability

• Optimize staffing
• Forecast cash flow

How to Calculate Prime Costs

The formula is straightforward:

Prime Cost = Cost of Goods Sold + Total Labor Costs

For example:

• Food Cost: $28,000
• Labor Cost: $35,000

Prime Cost = $63,000

If your monthly sales are $100,000, your prime cost percentage would be:

Prime Cost Percentage = (Prime Cost ÷ Total Sales) × 100

Prime Cost Percentage = ($63,000 ÷ $100,000) × 100 = 63%

Monitoring this percentage each month helps evaluate restaurant performance.

What Is a Good Prime Cost Percentage?
