Inventory Carrying Cost Calculator

Background.

A reader arrives at Inventory Carrying Cost Calculator to annualize capital, storage, service and risk costs against average inventory value. Carrying-cost percentage combines opportunity cost with warehousing, insurance, shrinkage, obsolescence and handling. For that reason, this page names its convention as “annual carrying cost = average inventory value × (capital cost rate + storage/service/risk rate).”

The editable entries are average inventory value, annual capital cost, annual storage, service and risk cost. Use values from the document or measurement that governs this inventory carrying cost question; the defaults are only the worked fixture below. Before relying on the number, check this inventory carrying cost boundary: purchase cost is not itself carrying cost, and seasonal average inventory should replace a single period-end balance.

IFRS Foundation, IAS 2 Inventories; inventory cost and expense recognition documents the convention or governing rule used here. The inventory carrying cost output is a transparent scenario under those facts: it does not manufacture an unentered market price, professional determination, carrier quote, legal eligibility finding or locally adopted code value.
