What this calculation means
A measured portion cost assigns a fraction of a finished batch’s cost to one portion. The fraction is portion quantity divided by finished yield.
The calculation retains proportional allocation. It does not charge all remainder to whole saleable portions.
How to use this calculator
Enter the batch total, its finished usable yield, and the quantity in one portion. Convert yield and portion into the same weight, volume, or count unit before entering them.
Formula and variables
Portion cost = Batch cost × Portion size ÷ Finished yield

Understand your result
The answer is the theoretical ingredient cost of one measured portion from this batch.
Worked example
A $24 batch yields 10 lb and each portion is 6 oz.
Batch cost: 24 USD
Finished yield: 160 same unit
Portion size: 6 same unit
- Convert 10 lb of finished yield to 160 oz before entry.
- A 6 oz portion is 6 ÷ 160 of the batch.
- Multiply $24 × 6 ÷ 160 = $0.90.
Example result: $0.90
Frequently asked questions
Can I divide pounds of yield by ounces per portion?
Convert the yield first. A 10 lb batch is 160 oz; a 6 oz portion then receives 6/160 of the batch cost.
Does the portion quantity have to be a whole number?
No. Measured portions can be fractional quantities. They still need to use the same unit as finished yield.
