# Inventory Analysis

Inventory Turnover Ratios
1. Inventory turnover ratio = Cost of goods sold / Average inventory
2. Days in inventory = 365 days / Inventory turnover ratio

Exercise
Cost of goods sold = \$60,000
Beginning inventory = \$12,000
Ending inventory = \$18,000

Calculate the following:
(1) Inventory turnover ratio
(2) Days in inventory

Average inventory = (Beginning inventory + Ending inventory) / 2
= (\$12,000 + \$18,000) / 2 = \$15,000
(1) Inventory turnover ratio = \$60,000 / \$15,000 = 4.0
(2) Days in inventory = 365 / 4.0 = 91.25

Inventory Errors
1. Cost of goods sold = Beginning inventory + Purchases – Ending inventory
2. If ending inventory is overstated, cost of goods sold is understated.
3. If cost of goods sold is understated, net income is overstated.
4. If ending inventory is understated, cost of goods sold is overstated.
5. If cost of goods sold is overstated, net income is understated.
