Capital covers financing or opportunity cost; storage covers space and handling; service covers insurance and systems; risk covers damage, shrinkage, obsolescence, and markdowns.
Compare the result with turnover, days on hand, reorder points, and economic order quantity for the same inventory scope.
Use average inventory at cost for the same period as annual costs.

Divide by average inventory value for carrying rate and by 12 for the monthly average.
Capital covers financing or opportunity cost; storage covers space and handling; service covers insurance and systems; risk covers damage, shrinkage, obsolescence, and markdowns.
Use one documented allocation policy and avoid counting the same cost twice.
Compare the result with turnover, days on hand, reorder points, and economic order quantity for the same inventory scope.
A high carrying rate identifies a burden but does not alone determine what to discontinue or reorder.
Use average inventory at cost for the same period as annual costs.
When average inventory is zero, the dollar total remains valid but carrying rate is unavailable.
Common components are capital, storage, service, and inventory risk costs for one consistent period.
Divide annual inventory holding cost by average inventory value and multiply by 100.
No. Storage is one component; holding cost also includes capital, service, and risk.
