Recipe & Yield

Food Yield Calculator

Use this food yield calculator when the amount you buy is not the same as the amount you can actually serve or use in a recipe. It helps turn purchase cost into usable cost after trim, peel, bone, drain, shrink, or cook loss.

Worked example

Example calculation

If 20 pounds of beef costs $80 and yields 16 usable pounds after trim, the usable yield is 80%. The raw purchase cost is $4.00 per pound, but the usable cost is $5.00 per pound because only 16 pounds are available for recipes.

Formula

Food Yield and Trim Loss Formulas

Yield tells you what percentage of a purchased ingredient remains usable. Use the usable unit cost for recipe costing when trim, drain, bone, peel, or cook loss is meaningful.

Usable yield percentageUsable Yield % = Usable Quantity / Purchase Quantity x 100

Trim loss percentageTrim Loss % = 100 - Usable Yield %

Usable unit costUsable Unit Cost = Purchase Cost / Usable Quantity

Steps

How to use this tool

01
Enter the purchase cost and purchase quantity from the invoice, case, or package.
02
Enter the usable quantity left after trim, peel, drain, bone, or cook loss.
03
Add an optional recipe amount used if you want to cost one portion or batch amount.
04
Use the usable unit cost in recipe costing instead of raw purchase cost when loss is meaningful.

Yield math

How to calculate food yield percentage

Food yield percentage compares the usable amount after prep with the original purchased amount. This is the number that tells you how much product remains after trimming, peeling, boning, draining, or cooking.

When yield is below 100%, the usable unit cost is higher than the raw purchase unit cost.

Food yield formula example
Step	Calculation	Result
Purchase quantity	Original case or package amount	20 lb
Usable quantity	Amount after trim	16 lb
Usable yield %	16 lb / 20 lb x 100	80%
Trim loss %	100% - 80%	20%
Usable unit cost	$80 / 16 lb	$5.00 per lb

Use cases

When yield changes food cost

Food yield examples
Ingredient	Yield issue	Costing impact
Whole produce	Peel, core, trim, or spoilage	Raises usable cost per pound or ounce
Meat or fish	Bone, fat, skin, trim, or cook loss	Changes portion cost and menu margin
Canned items	Drain weight differs from can weight	Recipe cost should use drained usable amount
Batch prep	Evaporation or hold loss	Actual saleable yield may be lower than recipe yield

Costing decision

Purchase cost vs usable cost

Purchase cost is useful for ordering and invoice checks. Usable cost is better for recipe costing, portion costing, and menu pricing when a meaningful part of the item is lost before service.

For example, a $4.00 per pound raw purchase cost becomes $5.00 per usable pound when the item yields 80%. Using the raw cost in a menu price check would understate the true food cost.

When to use purchase cost or usable cost
Use this number	Best for	Example
Purchase unit cost	Buying checks and supplier comparisons	$80 case / 20 lb = $4.00 per lb
Usable unit cost	Recipe costing and menu pricing	$80 / 16 usable lb = $5.00 per lb
Cost for amount used	Portion or batch costing	6 oz used x usable oz cost

Kitchen examples

Common ingredients where yield matters

Food yield examples by ingredient type
Ingredient type	Yield issue	Operator check
Whole beef, poultry, or fish	Bone, fat, skin, trim, or cook loss	Track usable pounds and portion weight
Leafy greens and herbs	Trim, wilt, spoilage, and washing loss	Use tested prep yield instead of case weight
Potatoes, onions, carrots	Peel, trim, and size variation	Compare peeled weight with purchase weight
Canned or jarred items	Drain weight differs from can weight	Cost from drained usable amount
Cooked batch items	Evaporation, shrink, and pan loss	Compare finished saleable yield with planned yield

Next step

How to use yield in recipe costing

After calculating usable unit cost, use that cost in your recipe or portion calculator. This is especially important for expensive proteins, produce-heavy recipes, drained items, and catering prep where small yield errors multiply across many guests.

If you are pricing one menu item, calculate the cost for the amount used, then send that number into the Food Cost Calculator or Food Cost Percentage Calculator.

Operator records

Yield records worth keeping

Food yield changes with supplier specs, prep method, product size, and cook time. Keep a simple record for ingredients where the loss is expensive enough to affect recipe cost or menu price.

Useful food yield records
Ingredient or prep item	Record this	When to re-test
Whole fish or meat	Purchase weight, trimmed weight, cooked weight, usable portions	Supplier spec, butcher method, or portion size changes
Trimmed vegetables	Case weight, peeled or trimmed weight, usable prep weight	Season, size, spoilage, or prep standard changes
Drained canned goods	Can weight, drained weight, usable drained amount	Brand or pack size changes
Cooked starches or grains	Dry weight, cooked yield, pan loss, saleable portions	Batch size, hold time, or cooking method changes

Pricing risk

Why small yield errors become expensive

A small yield mistake may look harmless on one portion, but it can become meaningful across a menu item that sells hundreds of times or a catered event serving dozens of guests.

If a recipe uses 6 ounces of an ingredient and the usable cost is off by $0.20 per ounce, the item cost is off by $1.20 before garnish, packaging, labor, or overhead are considered.

Watchouts

Common mistakes

Costing produce, meat, or drained items from purchase weight instead of usable weight.
Using one yield percentage for different supplier specs or prep methods.
Forgetting that cooked yield and raw trim yield are different checks.
Converting between weight and volume without density or a tested kitchen standard.

Costing note

Use yield-adjusted cost for pricing decisions

Use purchase cost for buying checks, but usable unit cost for recipe costing when trim or loss matters.
Keep tested yield records for expensive proteins, produce, drained cans, and batch prep items.
Update yield assumptions when supplier specs, prep methods, or portion standards change.

Frequently asked questions

What is food yield?

Food yield is the usable amount left after trim, peel, bone, drain, cook loss, or other preparation loss.

How do you calculate usable yield percentage?

Divide usable quantity by purchase quantity, then multiply by 100.

What is trim loss percentage?

Trim loss percentage is the part of the purchased ingredient that is not usable after prep. It equals 100 minus the usable yield percentage.

What is usable unit cost?

Usable unit cost is the purchase cost divided by the usable quantity after yield loss. It is often higher than the raw purchase unit cost.

Why does yield affect food cost?

If only part of the purchased ingredient is usable, the cost of the usable portion is higher than the raw purchase unit cost.

Should I use raw weight or cooked weight?

Use the weight that matches your costing decision. Use raw yield for trim checks and cooked or finished yield when the recipe is sold after cooking, draining, or holding loss.

Should I use yield for every ingredient?

Use it when loss is meaningful, especially for proteins, produce, drained products, expensive ingredients, or production batches with known shrink.
