What this calculation means
A purchase-unit cost puts a case or pack price on a comparable basis, such as dollars per pound or per piece. It is the starting point for comparing quotes with different pack sizes.
This is an as-purchased price. It does not account for trimming, cooking loss, or a different usable yield.
How to use this calculator
Choose the comparison unit. Express the full pack quantity in that unit, then enter the total price paid for the pack.
Formula and variables
Purchase-unit cost = Pack price ÷ Pack quantity
- Pack priceUSD
- Price paid for the pack.
- Pack quantitytarget unit
- Quantity in the unit you want to compare.
Dollar amounts display to cents, with exact half-cent values rounded away from zero; intermediate calculations keep full precision.
Understand your result
The displayed “unit” means the unit you chose for Pack quantity. Keep that unit on your purchasing record.
Worked example
Normalize a 24 lb case priced at $18.
Pack price: 18 USD
Pack quantity: 24 target unit
- A 24 lb case costs $18.
- Divide $18 by 24 lb: $0.75 per lb. The form calls this your chosen unit.
Example result: $0.75 / unit
Frequently asked questions
Is the cheapest case also the cheapest unit?
Not necessarily. Compare unit prices using identical units and product scope. A larger case can have a higher price per pound even if its total quantity is larger.
Can I compare products with different trim yields?
Use a usable-cost comparison after measuring each yield. This purchase-unit figure alone does not account for usable output.
