If a restaurant does $20,000 per week and the total cost of food and beverages is $7,000 for that week, then the food cost is considered 35 percent. If, at the same restaurant, labor (including payroll taxes and benefits) equal $5,000 for the week, then the labor cost is 25 percent.
Do this for each part of the menu item. You might have meat at $.75, rice at $.50 and vegetables at $1.25 for a total of $2.50. Then, you divide this by a per-determined percentage. The average food cost for most restaurants is around 25-35%. If you use 30%, you get $2.50 divided by 30% for a total of $8.33.
