According to the given information, Net realization value rule to ending inventory is $17
Net realization value = selling price - selling cost
= $30 - $4
= $26
Profit margin = 30% of selling price
= 0.3 × $30
= $9
NRV - profit margin = $26 - $9
= $17
- An asset's value is measured by its net realizable value (NRV), which is the sum of the proceeds from a sale less any selling expenses.
- NRV is a conservative method that accountants use to make sure an asset's value isn't overstated.
- It is a typical technique for assessing inventories and accounts receivable, and it is also used in cost accounting.
- NRV has drawbacks, including being a more complex method of evaluating asset values and the possibility that management assumptions won't be realized.
- Both generally accepted accounting principles (GAAP) and international financial reporting standards (IFRS) use NRV.
