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If market demand drops, or if goods become damaged or outdated, their original cost is no longer accurate.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.
In practice
Real-world examples.
Example
A fashion boutique holds winter boots that cost 5,000 pounds to buy. Due to a mild season, they can now only sell them for 3,000 pounds, and shipping costs will be 200 pounds. The net realisable value is 2,800 pounds.
Example
An office supply firm has 10,000 pounds worth of outdated printers. They must pay an electronics recycling service 1,500 pounds to collect and dispose of them safely, meaning the net realisable value is minus 1,500 pounds.
Example
A small organic farm produces jam costing 2,000 pounds to make. They plan to sell the jars at a local market for 3,500 pounds, after paying a stall fee of 300 pounds. The net realisable value for this batch is 3,200 pounds.
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. For example, if you have damaged stock you can sell for 1,000 pounds, and it costs 150 pounds to repair and 50 pounds to ship, the calculation is 1,000 - 150 - 50 = 800 pounds.Case study
Seen in the real world.
Oakwood Furniture Ltd manufactured a batch of dining tables that cost 50,000 pounds 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 pounds. Furthermore, Oakwood would need to pay a logistics firm 4,000 pounds 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 pounds minus disposal costs of 4,000 pounds equals 26,000 pounds. Because this figure was lower than the original production cost of 50,000 pounds, accounting rules required Oakwood to write down the inventory value by 24,000 pounds. 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.
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.
