Inventory cost (as part of Cost of Goods Sold), is determined in the following way:  

 

Starting Inventory+Inventory Purchases-Inventory Used for Personal Use-Finishing Inventory=Deductible Inventory Cost

 

You stated you started the year with $0 inventory (first year).  Throughout the year, let's say you purchased $30,000 of inventory items.  You personally used $250 for yourself, (non-deductible as an expense), and finished the year with $4750 of remaining inventory.  The amount of deductible expense is $25000.

 

Then, the following year, (after ending with $4750 in inventory), you purchase $45250 of additional inventory, $0 personal use, and finish the year with $2000 inventory in stock.  Your deductible inventory cost for that year would be $48,000.
