1 As a result, if LIFO method is used in a rising-price and increasing-inventory environment, more of the higher-cost goods (last ones in) will be accounted for in COGS as opposed to FIFO.2  Under this scenario, net income will be lower compared to a company that used FIFO accounting.IFO will use the cost of the old stock to determine the COGS, making the profitability ratio less reflective of the current economic reality.
