Yield test and portion verification sheet

Record purchased, trimmed, cooked, and served quantities with tare, units, equipment, and method before applying a measured yield or portion calculation.

A yield test is an observation record, not a source of universal percentages. This sheet preserves the product or recipe version, lot, method, equipment, stage input, gross output, tare, net usable output, and portion measurement. Record every stage separately. A cooking yield after trimming uses the trimmed amount as its input, while the overall yield relates the final output to the original purchase.

How to run and record a yield test

  1. Identify the test conditions. Record product or recipe version, supplier lot if relevant, date, preparation method, equipment, and the target output state.
  2. Measure the first stage input. Weigh the as-purchased product or the input to the stage being tested. Use a tared scale container and record the unit and state.
  3. Record each stage output. For trimming and cooking, create separate entries. Subtract container tare from gross weight before recording net usable output.
  4. Measure portions independently. Record actual weight or volume for the utensil and fill method used. Do not infer food weight from a scoop or ladle capacity.
  5. Review before applying a calculator. Check that stage output does not exceed input in a loss-only model, and that adjacent stage quantities and units match.

Each yield percentage belongs to one measured stage

  1. Start Purchased input

    Record quantity, unit, product form, and lot.

  2. Measure Trim output

    Net usable weight after tare; note retained trim.

  3. Measure Cook output

    Use the trim output as the cook-stage input.

  4. Use Apply measured yield

    Calculate stage or overall cost on matching states.

The output of one stage becomes the input to the next. The overall result relates the last output to the original purchase.

Choose the denominator for the question

Do not mix a stage yield, an overall yield, and a portion measurement in one ratio.

Measure each stage separately

Record an input and net usable output for one named stage. If cooking follows trimming, the trimmed output is the cooking input.

  • Weigh or measure with compatible units, recording container tare separately. Do not subtract weight from volume.
  • Name whether output includes retained trim, cooking liquid, added water, or other ingredients.
  • For portion checks, record utensil number and level versus heaped fill, then repeat measurements. Do not infer a weight from a scoop label.

Review the test before using a percentage

This sheet stores observations only. After reviewing units and states, enter the measured quantities in the corresponding yield, portion, or usable-cost calculator.

Enter one stage per record row

A 10 lb raw purchase leaves 8 lb after trimming. Cooking that trimmed amount produces 6.5 lb gross in a container that weighs 0.5 lb.

Inputs

As-purchased input
10 lb raw
Trim usable output
8 lb trimmed
Cooked gross weight
6.5 lb including container
Container tare
0.5 lb
Purchase cost
$40.00 for 10 lb
  1. Net cooked output = 6.5 lb gross − 0.5 lb tare = 6 lb cooked usable.
  2. Trim yield = 8 ÷ 10 × 100 = 80%. Cook-stage yield = 6 ÷ 8 × 100 = 75%.
  3. Overall yield = 0.80 × 0.75 = 60%; 10 lb × 60% = 6 lb cooked usable.
  4. Purchase cost per raw lb = $40 ÷ 10 = $4.00. Usable cost = $40 ÷ 6 lb = $6.6667…, displayed as $6.67 per cooked usable lb.
  • Tare check: 6.5 lb − 0.5 lb = 6 lb net cooked output
  • Cost allocation: $40 ÷ 6 lb = $6.67 per cooked usable lb

Result: 60% overall yield; $6.67 per cooked usable lb

Subtract tare before using gross output. Keep stage ratios and unit cost unrounded until display; percentages display to one decimal place and dollars to cents.

Avoid treating every difference as waste

Added ingredients, absorbed water, retained trim, evaporation, and measurement error need separate notes. A loss-only ratio is valid only when the recorded process supports it.

Keep the observation with its conditions

A useful yield record names the product, process, stage, units, tare, and output state. Calculate each stage against its own input, then combine linked yields only when their states line up. Repeat the test when product specifications or preparation methods change; the worksheet does not supply a default yield or calculate results.
