What this calculation means
Ingredient-use cost assigns part of a purchase to the quantity actually used in a recipe. A pack price is not the recipe line cost unless the whole pack is used.
Use quantities in the same preparation state. A purchased raw weight and a cooked recipe weight need a separate yield adjustment.
How to use this calculator
Record the paid pack price and its quantity first. Enter the recipe withdrawal in that same unit; convert it before using this tool if necessary.
Formula and variables
Used ingredient cost = Pack price ÷ Pack quantity × Recipe quantity used

Understand your result
The answer is the ingredient cost of the withdrawal, not the purchase total or the cost of a finished serving.
Worked example
Restaurant prep uses 2 lb from a 10 lb pack priced at $12.
Pack price: 12 USD
Pack quantity: 10 same unit
Recipe quantity used: 2 same unit
- One purchased pound costs $12 ÷ 10 = $1.20.
- Two pounds used cost $1.20 × 2 = $2.40.
Example result: $2.40
Frequently asked questions
Can I enter pounds for the pack and ounces for the withdrawal?
Not directly. Convert both quantities to one unit, or use the unit-conversion costing scenario. This form does not detect or convert units automatically.
Does the unused pack become a recipe cost?
No. Only the entered withdrawal is allocated to this recipe. The remaining purchased stock has not been consumed by this line.
