Historical Cost. Definition. Historical Cost is the original cost incurred in the past to acquire an asset. Historical Cost Convention requires assets to be recognized at their historical cost. Explanation. Assets need to be assigned some value in the accounting books.
Under the FIFO method, the oldest costs are assigned to inventory items sold, regardless of whether the sold items were actually purchased at that cost. When the number of inventory items purchased at the oldest cost is sold, the next oldest cost is assigned to sales. For example, if a company buys 10 widgets at $20 each, then buys 10 more at $19 each, the company would assign the $20 cost to the first 10 widgets it sells, then begin to assign the $19 cost. The last in, first out method is the exact opposite of the FIFO method, assigning the most recent inventory costs to items sold.
