Sticker price per pound runs roughly $8 to $12 for Select, $12 to $18 for Choice, $18 to $28 for Prime, and $25 and up for dry-aged. Trim, cooking shrink, and bone take 30 to 50 percent of the weight you paid for between the invoice and the plate. This guide converts any supplier quote into a cost per serving you can actually price against a 28 to 35 percent food cost target.

Prime Rib Cost per lb by Grade

USDA grade is the first pricing lever on a standing rib roast. The spread between Select and Prime is wide enough that the grade you buy decides whether the roast hits your target food cost at a sellable menu price. USDA retail price data tracks beef cut prices by grade over time, so you can pull current numbers instead of relying on last year's quote (USDA ERS retail beef prices).

Illustrative ranges for standing rib roast, per lb, US retail and wholesale:

Grade Typical range per lb What you get
Select $8 to 12 Leaner, less marbling, tighter yield
Choice $12 to 18 The restaurant workhorse
Prime $18 to 28 Heavy marbling, needs a premium menu price
Dry-aged $25 to 40+ 20 to 30% weight loss built into the price

Restaurant buyers see different numbers than grocery shoppers because you are quoting wholesale cases, often bone-in, with weekly price moves and no contract pricing. The per-lb figure is where the math starts. Your cost per serving sits behind it, and the gap between the two is where the margin lives. It starts with the bone (restaurant prime cost basics).

Why Bone-in Costs Less per Pound and More per Plate

A bone-in prime rib runs $2 to $4 less per lb than boneless. It also carries roughly 15 to 20 percent of its weight in bone you cannot sell, so every invoice dollar buys some product that never reaches a plate.

Price the roast on edible portion. A bone-in quote at $12/lb with 80 percent usable yield costs $15 per lb of servable meat. A boneless quote at $15/lb at near-full yield beats it, and the bigger invoice number wins.

Bone-in earns its keep two ways: when the per-pound gap is wide enough to beat the yield loss, and when the bone is part of the product, like a carved-to-order truck special where the presentation is what they are paying for.

Run both quotes through a yield-adjusted comparison before you buy. The food yield calculator converts an as-purchased price into cost per serving so you can see which cut costs less on the plate.

What You Lose Between the Invoice and the Plate

A standing rib roast loses weight at three stages:

  • Trim: 10 to 15% off for the fat cap and chine bone
  • Cooking shrink: 15 to 20% from moisture and fat rendering
  • Bone: 15 to 20% of the purchase weight, on a bone-in roast

The USDA's Institutional Meat Purchase Specifications define how rib primal yields are measured (USDA AMS), so supplier quotes should be comparable against those specs.

A Worked Example: One 15 lb Roast, Start to Finish

  1. Buy 15 lb of Choice at $12.99/lb. That is $194.85 out the door.
  2. Trim the fat cap and chine at 12 percent. You have 13.2 lb.
  3. Cooking shrink at 18 percent takes it to roughly 10.8 lb of servable meat.
  4. At 12 oz per portion, that is about 14 servings.
  5. True cost per serving: $194.85 ÷ 14 = $13.92. The invoice-only math would have told you $9.74.
  6. At a 32 percent target food cost, the plate prices at $43.50.

How to Convert Price per lb into Cost per Serving

Two steps. Divide the as-purchased price per lb by the yield percentage to get cost per usable lb. Then divide by the servings you actually cut.

A $12/lb Choice roast with 65 percent total yield (trim, shrink, and bone combined) costs $18.46 per usable lb. A 12 oz cooked portion of that runs $13.85. Prime at $16/lb with the same yield lands at $18.46 per serving, and Select at $9/lb comes in near $10.39.

The trap is pricing off the sticker. Charge $32 for the prime rib special assuming 30 percent food cost on a $12/lb purchase, and your real food cost is closer to 43 percent, because a 12 oz cooked portion comes from nearly a pound and a half of purchased product. Run every grade through the same worksheet before you set the menu price, then check the result against your target with the food cost percentage guide.

When Choice Beats Prime on the Menu

Put both grades through a 30 percent target and the sell prices split fast. Choice rib at $11/lb and Prime at $14/lb, 12 oz boneless portions, work out to $27.50 for Choice and $35.00 for Prime. From a truck window, a $35 plate is a hard sell. A $27.50 plate moves.

Prime earns its premium where customers already expect it: a steakhouse-style catering job, a holiday pre-order where buyers commit at a set price, or a menu where the word Prime is the draw itself. For weekly truck service, Choice usually wins, because the quality gap rarely carries a 25 to 30 percent higher sell price and both grades take the same trim and shrink losses. Both fall under the same USDA IMPS rib roast specs, so the bone-in versus boneless math applies to each the same way.

One tool limit worth knowing: the recipe calculator prices a recipe with one grade at a time, so a Choice-versus-Prime comparison means costing the recipe twice.

How to Compare Supplier Quotes Fairly

Two quotes are only comparable once they describe the same cut. Normalize every quote to cost per lb of edible, cooked portion before you decide.

A bone-in Choice standing roast at $9.99/lb with 55 percent total yield costs $18.16 per edible cooked lb. A boneless, trimmed quote at $13.50/lb with 75 percent yield costs $18.00. The cheaper sticker price loses.

Ask each supplier three things: bone-in or boneless, trim spec (deckle off or on), and case weight. A 72-lb case versus a 40-lb case changes how much sits in your cooler. It should never change the per-serving math.

If a supplier will not state a trim spec or yield, price the quote at the worse yield and decide from there. Buying on sticker price alone is how a 32 percent target quietly drifts to 38.

December and the Rib Spike

Rib primals spike hard in December. Whole rib eyes and standing roasts jump from everyday foodservice pricing to holiday retail demand, and the USDA's weekly boxed beef reports track the lift, with the cutout (the benchmark price for a box of rib primals) climbing through the weeks before Christmas and New Year.

Two moves protect you. First, pre-order the December roast before the retail rush, usually by mid-November, and lock the quote in writing. Second, price the holiday special off the December cost. Operators who price it off their summer cost per serving watch a 32 percent target become 40 percent. If the locked quote still stings, run the special on a cheaper cut and save prime rib for the shoulder weeks, when prices settle back down (holiday preorder math for bake season).

Keeping the Numbers Current Week to Week

A costing sheet is only as good as its newest price. A weekly loop takes minutes:

  1. Log your supplier run prices.
  2. Let the tool re-cost every recipe that touches beef.

Percy Plate stores an ingredient price once and pushes it through every recipe that uses it, so cost per serving and suggested sell price update without touching each dish. If Choice rib jumps $1.20/lb, the new food cost percentage is on the prime rib plate before the weekend, and you can reprice in time.

What the tool leaves to you: it will not fetch prices from your supplier, so the math is as fresh as your last entry. It will not negotiate contract pricing or forecast the December spike. Two-location operations with full accounting needs buy platforms built for that, though operators on r/restaurateur have questioned paying five figures a year at small scale. For a truck or a single kitchen, the trade is simple. You enter prices weekly, and the math stays live.

What You Can Do This Week

  1. Pull your last rib roast invoice and the current quote sitting next to it.
  2. Write down the yield you actually got: weighed purchase, weighed servings, one division.
  3. Run both quotes through the yield adjustment and compare cost per serving.
  4. Price the next special off the per-serving figure and let the invoice number stay on the invoice.

The Bottom Line

The per-lb figure is the beginning of the math, and the serving is the end of it. Trim, shrink, and bone take 30 to 50 percent of the purchased weight, the grade spread runs $8 to $28, and the cheaper invoice is often the more expensive plate. Convert before you commit, lock December quotes by mid-November, and refresh the entry every week.

FAQ

How much prime rib do I need per person?

Plan on 12 oz of cooked meat per serving. With trim, shrink, and bone consuming 30 to 50 percent of purchased weight, one serving requires roughly 1.25 to 1.5 lb of as-purchased bone-in roast. A 15 lb roast yields about 14 servings at that portion.

Is USDA Prime worth it for a food truck?

Usually it is not. Prime needs a 25 to 30 percent higher sell price to hold your target food cost, which pushes a 12 oz portion toward $35 from a truck window. Choice takes the same trim and shrink losses, so the quality gap rarely carries the price jump. Save Prime for catering jobs and holiday pre-orders where customers expect it.

How many servings come out of a 10 lb roast?

Boneless at 12 oz portions gives roughly 10 to 11 servings after cooking shrink. Bone-in drops to about 8 to 9 servings after the bone. At 10 oz portions, add about two servings to each figure. Cost the roast per serving before you promise a count.

What food cost percentage should a prime rib special hit?

Aim for 28 to 35 percent. Calculate it off the yield-adjusted cost per serving: a $12/lb roast priced at $32 on an assumed 30 percent actually runs closer to 43 percent once yield is factored in.

Why does my cost per serving come out to double the price per lb?

Because a 12 oz cooked portion starts as roughly a pound and a half of purchased product. Trim removes 10 to 15 percent, shrink takes another 15 to 20, and bone-in roasts carry 15 to 20 percent unsellable bone. Dividing the purchase price by total yield, then by servings, roughly doubles the effective cost.
