Button mushroom yields 90%
You buy button mushroom by its whole weight, but you only plate 90% of it. That 10% loss is real cost the invoice never shows — here's the math.
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.
Trimming the dry stem ends is the only real loss — mushrooms are nearly all usable.
Say your invoice shows $3.50 per lb of button mushroom (an example AP price).
At 90% yield, your real cost is $3.89 per lb EP — because $3.50 ÷ 0.90 = $3.89.
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 button mushroom?
Button mushroom typically yields 90% edible portion of its as-purchased weight, per the CIA Standard Yield Tables.
How much button mushroom is lost to trim?
About 10% 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 button mushroom?
Divide the as-purchased price by the yield: EP cost = AP price ÷ 0.90. At 90% yield, the trim makes your real plated cost meaningfully higher than the invoice price.
