What this calculation means
Subrecipe unit costing divides a prepared component’s batch total by its finished usable output. It provides a reusable cost basis for later recipe withdrawals.
Keep the output state and unit explicit. A raw ingredient quantity is not the finished usable subrecipe yield.
How to use this calculator
Enter the component batch total and its usable finished quantity or count. Choose the output unit you will also use in the parent recipe.
Formula and variables
Subrecipe cost per unit = Subrecipe batch cost ÷ Usable yield
- Subrecipe batch costUSD
- Total cost of the subrecipe batch.
- Usable yieldsame unit
- Finished usable quantity or count.
Dollar amounts display to cents, with exact half-cent values rounded away from zero; intermediate calculations keep full precision.
Understand your result
The result is the cost per your named output unit, such as one ounce of sauce.
Worked example
A $10 subrecipe batch yields 40 oz.
Subrecipe batch cost: 10 USD
Usable yield: 40 same unit
- Divide a $10 subrecipe batch total by 40 oz usable output.
- Each ounce receives $0.25.
Example result: $0.25 / usable unit
Frequently asked questions
Should I round the unit cost before multiplying a withdrawal?
Keep the unrounded allocation where possible and round the final dollar result. This page displays cents, which can hide precision for very small unit costs.
Can the yield be a piece count?
Yes, if the pieces are the declared usable output unit and later withdrawals use that same count basis.
