Objective. Students will calculate as-purchased cost, edible-portion cost, and plate cost for at least three protein items and apply a standard food-cost percentage formula to derive a target menu selling price.

Meat is almost always the most expensive ingredient on a plate. A chef who orders a whole beef tenderloin pays for every ounce that arrives on the dock — fat, silverskin, chain, and trim — but only a portion of that weight ever reaches the guest's plate. If you price a menu item using only the invoice price per pound, you will underprice it every time, eroding profit and threatening the restaurant's viability. Yield costing translates what you pay (the as-purchased cost) into what you actually serve (the edible-portion cost) so your menu prices reflect reality.
As-Purchased Cost per Pound (AP cost/lb)
This is simply the invoice price divided by the total weight purchased. Suppliers quote this directly, but always verify the unit — some invoices list price per kilogram or per case.
Yield Percentage
Yield percentage tells you what fraction of the AP weight is usable after trimming and fabrication.
> Yield % = (Edible Portion Weight ÷ As-Purchased Weight) × 100
For example, a whole beef tenderloin (PSMO — peeled, side muscle on) typically yields around 65–75% after removing fat, silverskin, and chain, depending on the cutter's skill and the desired end product. A bone-in pork loin will have a different yield than a boneless one. Chicken fabrication yield depends on whether you are portioning bone-in pieces or breaking down a whole bird to boneless, skinless breasts. Actual yield percentages vary; always weigh your specific product before and after fabrication to establish your house yield.
Edible-Portion Cost per Pound (EP cost/lb)
> EP cost/lb = AP cost/lb ÷ Yield %
(Express yield % as a decimal, e.g., 70% = 0.70)
This is the cost of one pound of usable product. It is always higher than the AP cost whenever yield is less than 100%.
Plate Cost
A plate-cost card lists every component of a finished entrée with its EP cost. Add the protein cost for the exact portion size, plus sauce and each side dish, to arrive at the total plate cost.
> Protein cost on plate = EP cost/lb × (Portion weight in lb)
Menu Selling Price
Once you know the plate cost, apply your target food-cost percentage:
> Menu Price = Plate Cost ÷ Target Food-Cost %
(Express as a decimal, e.g., 30% = 0.30)
A food-cost percentage between 28% and 35% is a common industry target for full-service restaurants, though the right number depends on the operation's full cost structure. Your instructor or operator will provide the target for each exercise.
Before you can cost anything, you must fabricate accurately and weigh every result. Use a calibrated portion scale. Record the AP weight before you start, then weigh the trimmed, usable product afterward. The difference is trim loss. Save trim notes — some trim (beef chain, pork trim) has secondary value for grinding or stocks; sophisticated costing may credit that value, but for introductory worksheets, treat trim as zero-value unless instructed otherwise.
Fabrication skills directly affect profitability. Two cooks breaking down the same tenderloin can produce meaningfully different yields. Consistent knife technique, proper silverskin removal, and minimizing over-trimming all protect margin.
Market prices for beef, pork, and poultry change regularly based on feed costs, supply chain conditions, and seasonal demand. A 15% rise in the AP cost of beef tenderloin directly raises the EP cost by 15% (assuming yield stays constant), which in turn raises the plate cost and — if the formula is followed — the menu price. When price increases threaten to push a menu price above what guests will accept (the perceived-value ceiling), chefs evaluate alternative cuts.
When proposing a substitution, you must consider:
The ACF Certified Culinarian exam includes food costing and menu pricing as a tested knowledge area. Mastery of AP/EP conversion, plate costing, and food-cost percentage calculation is expected. ServSafe principles intersect with fabrication: raw meat must be handled at safe temperatures (refrigerate below 41 °F / 5 °C), and cross-contamination must be prevented by using dedicated cutting boards and sanitizing surfaces between proteins. These food-safety habits are not separate from costing — spoilage and recalls are the costliest yield losses of all.
In professional kitchens, a rounding error on EP cost compounds across hundreds of portions. Carry calculations to at least two decimal places. Double-check your arithmetic before submitting any costing document. A math error in a real purchasing decision can wipe out a week of profit.
Answer each question, then check it. Nothing is recorded; this is your own practice.
