How does the FIFO method affect the inventory turnover ratio compared to the LIFO method during periods of rising inventory costs?

During periods of rising inventory costs, the FIFO method results in higher inventory balances and lower cost of sales compared to the LIFO method. This leads to a lower inventory turnover ratio for FIFO, while LIFO shows a higher turnover ratio due to its higher cost of sales and lower inventory levels.

The FIFO method allocates the cost of older, cheaper inventory to cost of goods sold, resulting in lower costs and higher inventory balances during inflationary periods. In contrast, the LIFO method reflects the current higher costs in cost of sales, leading to lower inventory values. Consequently, the inventory turnover ratio, calculated as cost of sales divided by average inventory, will be higher under LIFO and lower under FIFO during rising cost periods.
