@denesp I am not sure but to some SE about hardware or accounting. I don't really see any economic content about pricing (or valuation) issue on the question as it concerns a very specific example.

@optimalcontrol I agree it's off topic. I just don't think there is another SE site where it belongs. This does not make it on topic here though, I just found your argument misleading.

# Estimating the cost of an assett that needs to be replenished

(Asked by: username_0 on 2016-02-22)

I am working with hard drives. For simplicity, let's say all drives have the same capacity, 1TB and all cost $100.

They typically last about 4 years, when they need to be replaced. They drop in price about 50% over that period of time. They cost 100 dollars for the first for years, $50 for the next 4 years, etc.

What's the usual way of estimating the cost of something like this?

The retail price should include the total net present value of use of the item. At any given point in time, the value of the item is the purchase cost minus accumulated depreciation. Depreciation should include both physical wear and any non-physical types of depreciation such as obsolescence.
