Shiitake mushroom yields 85%
You buy shiitake mushroom by its whole weight, but you only plate 85% of it. That 15% 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 $8.00 per lb of shiitake mushroom (an example AP price).
At 85% yield, your real cost is $9.41 per lb EP — because $8.00 ÷ 0.85 = $9.41.
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 shiitake mushroom?
Shiitake mushroom typically yields 85% edible portion of its as-purchased weight, per the CIA Standard Yield Tables.
How much shiitake mushroom is lost to trim?
About 15% 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 shiitake mushroom?
Divide the as-purchased price by the yield: EP cost = AP price ÷ 0.85. At 85% yield, the trim makes your real plated cost meaningfully higher than the invoice price.
