The gross-profit method estimates ending inventory when direct quantity-and-cost evidence is unavailable or incomplete. It uses a supported gross-margin relationship to estimate cost of goods sold, then subtracts that estimate from goods available at cost. It does not observe ending units.
Begin with controlled opening inventory, net purchases, and net sales. Apply the historical gross-margin rate to net sales, not to cost, unless the rate is explicitly stated on another basis. Subtract estimated gross profit from sales to obtain estimated cost of goods sold. Subtract that amount from goods available at cost to estimate ending inventory. Reconcile the two cost assignments.
The rate needs its own evidence. Test product and channel mix, markdowns, inflation, returns, theft, damage, unusual transactions, and changes after the historical period. State the purpose, such as interim reporting, insurance support, or a reasonableness check. Compare the estimate with later counts or other stronger evidence and explain differences.
ASC 330-10-05-3 describes the reporting-date inventory balance, but Topic 330 does not supply a general gross-profit-method formula in the local source reviewed here. The method therefore needs a stated purpose and other applicable support. Do not present the link as formula authority.
Use the Cedar estimation example before completing Northstar practice.
Put the concept to work
Understand this concept
- Explain how a historical gross-margin rate estimates cost of goods sold and ending inventory and why the estimate does not replace a required physical count or current mix evidence.
Apply this concept
- Compute estimated cost of goods sold and ending inventory from controlled sales and goods available, then challenge the historical margin for mix, markdown, loss, and period relevance.
