I recently tapped into a great set of tools for doing quick operational calculations created by Brock Markarian at RestaurantCalcs.com. This is a free suite of calculators for running food, recipe, and labor costs. Additionally, there are calculators for calculating menu pricing, liquor pour costs, draft beer/keg costs, break-even analysis, inventory variance, prime costs, the cost of customer reservation no-shows, and menu engineering.

Check out the calculator below and go to Restaurantcalcs.com for all of their calculators.
