Cost of goods sold is usually the largest expense on the income statement of a company selling products or goods. Cost of Goods Sold is a general ledger account under the perpetual inventory system .
Under the periodic inventory system there will not be an account entitled Cost of Goods Sold. Instead, the cost of goods sold is computed as follows: cost of beginning inventory + cost of goods purchased (net of any returns or allowances) + freight-in – cost of ending inventory.
This account balance or this calculated amount will be matched with the sales amount on the income statement.
