INCREMENTAL OPERATING ECONOMICS
Marginal Cost
Marginal cost is the change in total cost associated with an additional increment of output or activity. The relevant increment and operating range must be specified when using it in a logistics decision.
MARGINAL COST IN PRACTICE
- Define the incrementState the extra units, orders or service.
- Identify the changeInclude costs caused by that increment.
- Check the thresholdReview capacity and wider effects.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
One more order can trigger more than one label.
A warehouse can process a small additional order within existing capacity. A larger increase may require another shift. The decision therefore tests the relevant volume rather than extending one incremental estimate indefinitely.
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.

Can capacity thresholds change the result?
Yes.
Does it alone determine a good selling price?
No. The full commercial context still matters.
