    Hello,I am trying to understand inventory carrying costs for a class I am taking. In everyones opinion what would you say are some of the main problems in gathering info for calculating inventory carrying costs for a business?



    First look at the elements of this cost:
    1. Invested capital
    2. Cost of storage space
    3. Risk of spoilage (outdated deteriorated, stolen, etc.)
    The difficulty of monetarizing these is the following:
    1. Challenge: Getting your firm’s marginal cost of capital out of Finance; if you accomplish that then apply that interest cost to the capital cost of the lesser inventory dollar amount to establish an ongoing interest cost savings. However the benefit you don’t capture here is “What does freeing this capital do for your business in other arenas? Can you expand? Does your credit rating and therefore borrowing costs improve? Does the market value this and increase stock prices? Many issues.
    2. Calculate how much less space you need to store stuff. Challenge: Is this a marginal cost? Even if you don’t need the space, is it a variable cost? Can you get rid of it? If you can then calculate the lease payment savings, operating costs, etc.
    3. Challenge: Spoilage costs are very dificult to calculate. What inventory becomes unusable because of time in the warehouse – that part is pretty straightforward. But, do you really know what spoils or do you use it anyway and create warranty issues? Do you know what’s stolen? Do you know the impact of technological changes that devalue your inventory. This is a complex subject.
    So there you go, it’s tricky.



    Thank you for explaining it to me; I was having a hard time putting it all together but I was thinking of some of the areas in the right manner, which is a good sign. It is very complex.

    The carrying costs are upto the CFO/Controller and how they wish to
    allocate costs etc.
    The rate will be between “base” plus 2% and 25% and I’ve even seen
    33%. Adam
