LOGISTICS SYSTEMS & MEASUREMENT
Unit Cost
Unit cost is the cost attributed to one defined unit, commonly calculated as included cost divided by the corresponding quantity. The result depends on its cost scope, period and denominator.
UNIT COST IN PRACTICE
- Define the costState included components and period.
- Choose the quantityUse a matching output unit.
- Calculate and reviewDivide consistently and test changes.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
$1,200 across 600 accepted units.
A hypothetical activity incurs $1,200 of included cost for 600 accepted units: $2 per accepted unit. Dividing by 1,000 attempted units would answer a different question. The calculation needs the denominator and treatment of rejects to be explicit.
WHAT THIS MEANS FOR YOUR QUOTE
Agree the requirement before comparing quotes
Use the actual shipment, stock and service requirements. Record the billing unit, included work and responsibility for exceptions.
Put this term to work. Use the 3PL pricing and rates guide for the wider invoice context and the guide to comparing 3PL quotes to compare the same scope, activity profile and billing units.
