What is prime cost?

Prime cost is your food and drink cost plus your staff cost. Together they are the two largest costs in almost every restaurant, and the two you can change week by week.

Prime cost % = (Food and drink used + Staff cost) ÷ Sales × 100Include wages, overtime, benefits and staff meals in staff cost.
