Red onion yields 88%

You buy red onion by its whole weight, but you only plate 88% of it. That 12% 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.

Papery skin and the root end are the only real loss; most of the bulb plates.

Say your invoice shows $1.20 per lb of red onion (an example AP price).

At 88% yield, your real cost is $1.36 per lb EP — because $1.20 ÷ 0.88 = $1.36.

AP price is illustrative; the EP figure is computed (AP ÷ yield). Use your real invoice price below.

Common questions

What is the yield of red onion?

Red onion typically yields 88% edible portion of its as-purchased weight, per the CIA Standard Yield Tables.

How much red onion is lost to trim?

About 12% 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 red onion?

Divide the as-purchased price by the yield: EP cost = AP price ÷ 0.88. At 88% yield, the trim makes your real plated cost meaningfully higher than the invoice price.
