PUTTING IT INTO PRACTICE
Edible Portion Yield: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Purchased weight (g) | 1,000 |
| Trim loss (%) | 20 |
| Result | 800 g |
- Check the input labels and enter the example values above.
- Apply the relationship: Edible weight = purchased weight × (1 − loss/100).
- The result is 800 g, rounded for display.
How to interpret your result
The loss percentage is specific to the ingredient and preparation process.
Raw, cooked and trimmed weights are different measurement stages. An edible-yield percentage describes the remaining share after preparation. Scaling ingredient amounts does not automatically scale cooking time.
Frequently asked questions
Should portion weights use raw or cooked food?
Use whichever basis your recipe or serving plan requires, and state it consistently. Do not compare raw weights directly with cooked weights.
When is the edible portion yield calculator useful?
Use edible yield rather than purchase weight when costing a recipe made from trimmed ingredients.
How do I use the edible portion yield calculator?
Enter purchased weight (g), trim loss (%). The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Edible weight = purchased weight × (1 − loss/100).
What should I check before using the result?
The loss percentage is specific to the ingredient and preparation process.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
