Russet potato yields 81%
You buy russet potato by its whole weight, but you only plate 81% of it. That 19% 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.
Peel loss is real; skin-on prep recovers most of it when the dish allows.
Say your invoice shows $0.80 per lb of russet potato (an example AP price).
At 81% yield, your real cost is $0.99 per lb EP — because $0.80 ÷ 0.81 = $0.99.
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 russet potato?
Russet potato typically yields 81% edible portion of its as-purchased weight, per the CIA Standard Yield Tables.
How much russet potato is lost to trim?
About 19% 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 russet potato?
Divide the as-purchased price by the yield: EP cost = AP price ÷ 0.81. At 81% yield, the trim makes your real plated cost meaningfully higher than the invoice price.
