What is Yield?
Yield is how much usable product you get out of what you bought or prepared. In bars and kitchens it means two related things:
Product yield: the share of a product that's usable after prep. A case of limes is mostly peel and pulp; only the juice ends up in the glass.
Recipe yield: how much a prep recipe makes. A batch of lime juice yields 32 oz; a batch of syrup yields 48 oz.
Both do the same job in costing: they turn what you paid into what each usable ounce, pound, or serving actually costs.
The Formulas
Product yield:
Usable Amount ÷ Purchased Amount = Yield %
Cost per Purchased Unit ÷ Yield % = True Cost per Usable Unit
Recipe yield:
Total Batch Cost ÷ Batch Yield = Cost per Unit of the Batch
Quick Example: Product Yield
You buy 10 lb of onions at $0.60/lb. After peeling and trimming, you have 9 lb usable.
Yield: 9 ÷ 10 = 90%
True cost: $0.60 ÷ 0.90 = $0.67 per usable pound
If your recipe cost uses $0.60, every dish with onions is costed about 11% low.
Quick Example: Recipe Yield
Fresh lime juice, from How To Cost A Drink:
30 limes at $0.50 each: $15
30 minutes of barback time: $10
Batch yield: 32 oz of juice
Cost per ounce: $25 ÷ 32 = $0.78
Without yield, you'd know the batch cost $25 but not what the 1 oz of lime juice in a Daiquiri costs.
Why It Matters
Ingredients with low yield cost more than their invoice price suggests. Citrus is the classic bar example.
Every sub-recipe, from syrups and juices to infusions and batches, needs a yield before its cost can carry into a drink.
Yield shows where a technique pays for itself. Super Juice gets far more liquid out of each lime, which can cut the cost per ounce sharply.
What Affects Yield
Season and size: limes in winter can give noticeably less juice than limes in summer.
Technique and equipment: a hand press, an electric juicer, and a Sunkist-style machine give different yields from the same case.
Prep loss: trimming, peeling, straining, and evaporation in cooked syrups.
Method: fat washing, clarification, and infusions all lose some liquid along the way.
Common Mistakes
Costing at the invoice price A $50 case of limes doesn't make $50 of lime juice at 100% yield. Cost the usable product, not the purchase.
Measuring yield once Yield changes with seasons, suppliers, and staff. Re-measure a few times a year, especially for citrus.
Guessing batch yields Measure what the batch actually makes. A syrup recipe that "makes about a quart" might make 28 oz.
Forgetting labor A high-yield method that takes twice as long might not save money. Count prep time in the batch cost.
Yield vs Shrinkage
Yield is expected, planned loss: peels, trim, pulp.
Shrinkage is unplanned loss: spills, overpours, waste, theft.
Yield belongs in your recipe costs. Shrinkage shows up as Inventory Variance.
FAQ
How much juice is in a lime? It varies, usually around an ounce. The juice example above got about 1.07 oz per lime. Measure your own; it changes by season and supplier.
What's a yield percentage? The usable amount divided by the amount purchased. 9 lb usable from 10 lb purchased is a 90% yield.
What's the difference between yield and batch size? Batch size is what you put in. Yield is what you get out. They're rarely the same.
Does yield matter for spirits? For a straight pour, not much. For infusions, fat washes, and clarified cocktails, yes: you lose some volume in the process.

Bottom Line
Yield is the difference between what you paid for and what you can actually use. Measure it for your citrus and every prep recipe, and your drink costs stop running low.
