What it means
In business, you often hold items like stock, products, or materials that you plan to sell. Accounting rules dictate that you must value these items at what they are actually worth today, not what you originally paid for them.
If market demand drops, or if goods become damaged or outdated, their original cost is no longer accurate. This is where net realisable value comes in, acting as a reality check for your assets.
To calculate it, you look at the expected selling price and subtract any expenses required to make the sale happen. These might include packaging costs, delivery fees, or minor repairs needed to get the item into a sellable condition.
If this final figure is lower than what you paid to acquire or make the item, accounting standards require you to write down the value of that inventory on your financial statements. Why does this matter for non-finance managers?
It protects your business from nasty surprises and paints an honest picture of your financial health. If you pretend damaged or obsolete stock is still worth its original price, your profits and assets will look healthier than they really are.
By using net realisable value, you ensure your balance sheet reflects true, cautious business sense. In daily practice, warehouses and retail managers review aging stock regularly.
If winter coats fail to sell and must be heavily discounted alongside clearance fees, the net realisable value helps decide the exact loss to record. It prevents managers from kidding themselves about past buying mistakes and keeps inventory tracking grounded in reality.
Imagine trying to sell your old car. You bought it for $10,000, but it has a dent now.
A dealer offers $4,000, but you must pay $200 for a safety check first. Your net realisable value is $3,800.
In practice
Real-world examples
Example 1
A fashion boutique holds winter boots that cost $5,000 to buy. Due to a mild season, they can now only sell them for $3,000, and shipping costs will be $200. The net realisable value is $2,800, so the boutique writes the boots down by $2,200 and plans a clearance sale.
Example 2
An office supply firm has $10,000 worth of outdated printers. They must pay an electronics recycling service $1,500 to collect and dispose of them safely, meaning the net realisable value is minus $1,500. In practice the printers are written down to zero and the $1,500 disposal cost is also recognised as an expense.
Example 3
A small organic farm produces jam costing $2,000 to make. They plan to sell the jars at a local market for $3,500, after paying a stall fee of $300. The net realisable value for this batch is $3,200, which is above cost, so no write-down is needed and the jam stays on the books at $2,000.
Think of it
Imagine trying to sell your old car. You bought it for 10,000 pounds, but it has a dent now. A dealer offers 4,000 pounds, but you must pay 200 pounds for a safety check first. Your net realisable value is 3,800 pounds.
Formula
Calculation
Net Realisable Value = Estimated Selling Price - Estimated Costs of Completion and Disposal
Worked example: you have damaged stock you can sell for $1,000, and it costs $150 to repair and $50 to ship, so net realisable value = $1,000 - $150 - $50 = $800.
Now compare it with cost. If the stock originally cost $1,100, the net realisable value of $800 is lower, so you write the stock down by $1,100 - $800 = $300 and record that as an expense. If the stock had cost only $700, you would leave it at cost, because inventory is carried at the lower of cost and net realisable value.Case study
Seen in the real world
This is a fictional, illustrative scenario. Oakwood Furniture Ltd manufactured a batch of dining tables that cost $50,000 to produce. Unfortunately, a sudden shift in interior design trends meant these specific tables fell out of favour, and customer demand dried up. The sales manager estimated that the tables could now only be cleared through a discount warehouse for a total of $30,000.
Furthermore, Oakwood would need to pay a logistics firm $4,000 to transport the bulky items to the clearance buyer. Using the net realisable value formula, the finance team calculated the true worth of the inventory: Estimated selling price of $30,000 minus disposal costs of $4,000 equals $26,000. Because this figure was lower than the original production cost of $50,000, accounting rules required Oakwood to write down the inventory value by $24,000. This adjustment immediately reduced the company profit for that quarter, providing an honest, realistic view of their financial position to the bank and company directors, avoiding inflated asset figures.
Two quarters later a second clearance buyer offered $34,000 for the same tables, with the same $4,000 transport cost. The new net realisable value was $34,000 - $4,000 = $30,000, so Oakwood reversed $4,000 of the earlier write-down, raising the carrying value from $26,000 to $30,000. The reversal was allowed because $30,000 was still below the original cost of $50,000.
Watch out
Common mistakes
- Using the original purchase price instead of the current expected selling price.
- Forgetting to subtract the costs needed to package, repair, or ship the goods.
- Applying the rule to all inventory at once instead of assessing items individually.
Questions
People also ask
How often should a business calculate net realisable value?
Most companies review their inventory values at the end of each reporting period, such as monthly, quarterly, or annually, or whenever market conditions change drastically.
Is net realisable value the same as market value?
Not quite. Market value is what the item generally costs to buy or sell right now, whereas net realisable value specifically focuses on the expected selling price minus the specific costs to complete and sell it.
What happens if the net realisable value goes back up later?
Under international accounting standards, if inventory values recover later, you can reverse previous write-downs up to the original cost amount, but not higher.
