The Most Common Restaurant Performance Metrics Explained

Step into any restaurant operations meeting, and you will hear terms like RevPASH, COGS, Prime Cost, and Table Turn Time. If you don't know what these metrics mean or how to calculate them, you cannot measure your restaurant's performance accurately. Let's break down these essential metrics into plain, actionable terms.

A Real-World Case Study: A cafe owner had high daily sales but struggled to pay supplier invoices. He calculated his Prime Cost and realized it was 68% of sales due to overstaffing and high waste. He set a target of 60% and restored his cash flow.

Core Metrics to Understand

• Cost of Goods Sold (COGS): Calculation: (Beginning Inventory + Purchases) - Ending Inventory. Tracks the total cost of ingredients used to generate food and beverage sales.
• Revenue Per Available Seat Hour: Calculation: Total Sales / (Total Seats * Hours Open). Measures how efficiently you use your physical seating capacity during service.
• Prime Cost (Target: 60%): Calculation: COGS + Total Labor Costs. The most critical metric for assessing restaurant profitability, showing total operational efficiency.
• Labor Cost Percentage: Calculation: Total Payroll / Total Sales. Tracks how much you spend on labor to generate your sales. Aim for 25% to 30%.

Analyzing Sales Trends and Inventory Variance Reports

Data should drive your restaurant decisions. Review your Product Mix (PMix) report weekly to identify popular and slow dishes. Compare actual inventory levels against theoretical usage based on sales recipes to identify kitchen waste or portion control issues. Stagger labor schedules based on hourly sales traffic logs, matching labor spend directly to guest traffic. Use reservation conversion tracking to monitor how many website visitors complete bookings, optimizing the funnel to capture every diner.

The Hidden Pitfall to Avoid

Do not calculate these metrics using estimated inventory values. Conduct actual physical stocktakes to ensure your COGS and Prime Cost calculations are 100% accurate.

Actionable Consultant Takeaway

Understand the formulas behind your business. Calculate COGS, labor cost, RevPASH, and Prime Cost regularly to evaluate your operations and margins.
