What is prime cost and why should a restaurant track it monthly?
Prime cost is your cost of goods sold (food, beverage, paper) plus total labor (wages, payroll taxes, benefits), expressed as a percentage of sales. Full-service restaurants typically aim for 60–65%; quick service and bars can run lower. It's the single number that tells you whether a restaurant is viable, and it changes week to week with pricing, waste, and scheduling. We report it every month with a trend line, so a bad month shows up before it becomes a bad quarter.
