Estimating Inventories
Companies sometimes need to determine the value of inventory when a physical count is impossible or impractical. For example, a company may need to know how much inventory was destroyed in a fire. Companies using the perpetual system simply report the inventory account balance in such situations, but companies using the periodic system must estimate the value ofinventory. Two ways of estimating inventory levels are the gross profit method and the retail inventory method.
Gross profit method. The gross profit method estimates the value of inventory by applying the company's historical gross profit percentage to current-period information about net sales and the cost of goods available for sale. Gross profitequals net sales minus the cost of goods sold. The grossprofit margin equals gross profit divided by net sales. If a company had net sales of $4,000,000 during the previous year and the cost of goods sold during that year was $2,600,000, then gross profit was $1,400,000 and the gross profit margin was 35%.
Net Sales
$ 4,000,000
Less: Cost of Goods Sold
(2,600,000)
Gross Profit
$ 1,400,000








If gross profit margin is 35%, then costof goods sold is 65% of net sales.
Suppose that one month into the current fiscal year, the company decides to use the gross profit margin from the previous year to estimate inventory. Net sales for the month were $500,000, beginning inventory was $50,000, and purchases during the month totaled $300,000. First, the company multiplies net sales for the month by the historical gross profit marginto estimate gross profit.







Next, estimated gross profit is subtracted from net sales to estimate the cost of goods sold.
Net Sales
$ 500,000
Gross Profit
(175,000)
Cost of Goods Sold
$ 325,000

Alternatively, cost of goods sold may be determined by multiplying net sales by 65% (100% – gross profit margin of 35%).
Finally, the estimated cost of goods sold is subtracted fromthe cost of goods available for sale to estimate the value of inventory.
Beginning Inventory
$ 50,000
Purchases
300,000
Cost of Goods Available for Sale
350,000
Less: Cost of Goods Sold
(325,000)
Ending Inventory
$ 25,000

The gross profit method produces a reasonably accurate result as long as the historical gross profit margin still applies to the current period. However, increasingcompetition, new market conditions, and other factors may cause the historical gross profit margin to change over time.
Retail inventory method. Retail businesses track both the cost and retail sales price of inventory. This information provides another way to estimate ending inventory. Suppose a retail store wants to estimate the cost of ending inventory using the information shown below.

$ 400,000

The first step is to calculate the retail value of ending inventory by subtracting net sales from the retail value of goods available for sale.

$ 258,000
430,000
Net Sales

400,000
Ending Inventory (Retail)

$ 30,000

Next, the cost-to-retail ratio is calculated by dividing the cost of goods available for sale by the retail value of goods available for sale.

Cost

$ 49,000

209,000
350,000
Goods Available for Sale
$ 258,000
430,000
Net Sales

400,000
Ending Inventory(Retail)

$ 30,000
Cost to Retail Ratio ($ 258,000 + $ 430,000 = 60%)



Then, the estimated cost of ending inventory is found by multiplying the retail value of ending inventory by the cost-to-retail ratio.
