Whole crab yields 25%
You buy whole crab by its whole weight, but you only plate 25% of it. That 75% loss is real cost the invoice never shows — here's the math.
At 25% yield, whole crab carries a ×4.00 trim tax: its usable part costs the invoice price times 4.00.

Yield is the fraction of an ingredient that actually reaches the plate after you clean, peel, and trim it. What you pay is the AP (as-purchased) price; what it costs on the plate is the EP (edible-portion) price.
Shell, head, and water weight are the loss — shellfish yields are the lowest in the kitchen, so the cost per usable ounce runs high.
Say your invoice shows $8.00 per lb of whole crab (an example AP price).
At 25% yield, your real cost is $32.00 per lb EP — because $8.00 ÷ 0.25 = $32.00.
AP price is illustrative; the EP figure is computed (AP ÷ yield). Use your real invoice price below.Yield breakdown

Common questions
What is the yield of whole crab?
Whole crab typically yields 25% edible portion of its as-purchased weight, per the CIA Standard Yield Tables.
How much whole crab is lost to trim?
About 75% of the as-purchased weight is lost to cleaning, peeling, and trimming before it reaches the plate.
How do you calculate the edible-portion cost of whole crab?
Divide the as-purchased price by the yield: EP cost = AP price ÷ 0.25. At 25% yield, the trim makes your real plated cost meaningfully higher than the invoice price.
One ingredient's trim is the tax above — a plate stacks ten of them. The calculator adds them up.
