Costs

To determine the specific carrying cost for a product, we first have to determine what factors of the carrying cost will not vary by item. These are the factors that are solely dependent on cost or value of the average on-hand quantity:

* Insurance and taxes
* Opportunity cost of the money invested in inventory

If you take the total amount of these two elements and divide it by the average inventory value, the result is the cost of these elements per dollar of your average inventory investment. We will call it the ITO (Insurance, Taxes, and Opportunity Cost) factor.
