Thyme yields 50%
You buy thyme by its whole weight, but you only plate 50% of it. That 50% 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.
Leaves are what you plate; the stems are the loss. Stem-on herbs can shed half their weight to picking.
Say your invoice shows $2.50 per bunch of thyme (an example AP price).
At 50% yield, your real cost is $5.00 per bunch EP — because $2.50 ÷ 0.50 = $5.00.
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 thyme?
Thyme typically yields 50% edible portion of its as-purchased weight, per the CIA Standard Yield Tables.
How much thyme is lost to trim?
About 50% 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 thyme?
Divide the as-purchased price by the yield: EP cost = AP price ÷ 0.50. At 50% yield, the trim makes your real plated cost meaningfully higher than the invoice price.
