Net Realisable Value in Inventory: Why What You Paid Is Not Always What It’s Worth
My father used to run a small electronics shop in the 1990s. Every year he would order stock based on what was selling well at the time. And every year, without fail, some of that stock would sit on the shelves far longer than expected. By the time he tried to clear it, the selling price had dropped, sometimes dramatically. He was still recording that inventory at what he paid for it. But what he could actually get for it was a completely different number.
That gap between what something cost you and what you can actually sell it for is exactly what Net Realisable Value is about.
What Net Realisable Value Actually Means
At its core, NRV is a reality check.
When a business holds inventory, there is a natural temptation to value it at what was paid for it. That number is clean, documented, and easy to justify. But accounting does not allow companies to simply ignore the fact that circumstances change. If the inventory can only be sold for less than it cost, that loss in value needs to be recognised.
Net Realisable Value is defined as the estimated selling price of the inventory in the ordinary course of business, minus any estimated costs still needed to complete the product and any costs required to make the sale happen.
In simpler terms: what will you actually walk away with after selling this inventory, once you account for everything it still costs to get it out the door?
That is the number that matters.
Where It Sits in Accounting Standards
Under both International Accounting Standards and most major accounting frameworks, inventory must be valued at the lower of cost or net realisable value. This is often referred to simply as the lower of cost or NRV rule.
The logic behind this is conservative by design. Accounting generally does not allow businesses to record assets at more than they are actually worth. If inventory has declined in value, that decline should show up on the books now, not later when the sale eventually happens and the shortfall becomes impossible to ignore.
This principle protects the people reading financial statements. If a company is sitting on inventory that has quietly become worth less than what they paid for it, investors and creditors deserve to know that before they make decisions based on those numbers.
When Does NRV Become Relevant
This is where it gets practical.
Inventory rarely loses value for no reason. There are usually specific circumstances that trigger the need to compare NRV against cost and potentially write the value down.
Damaged goods are the most obvious case. If stock has been physically damaged during storage or transit, the price a buyer will accept is almost certainly lower than the original cost. The business needs to reflect that.
Obsolescence is another major one. Technology products are a classic example here. A phone model that cost a distributor a certain amount per unit becomes significantly harder to sell at that price the moment a newer model is announced. Fashion and seasonal goods face similar issues when a season ends.
Sometimes the issue is simply falling market prices. If the cost of raw materials in a market drops sharply, finished goods made from those materials may also fall in selling price, even if the goods themselves are perfectly fine.
And sometimes the problem is that additional costs to complete or sell the inventory are higher than originally expected, which reduces what the business will net from the transaction.
In any of these situations, if NRV falls below cost, the inventory must be written down.
A Practical Example Worth Walking Through
Say a clothing retailer purchased a batch of winter jackets at a cost of three thousand rupees per unit. The plan was to sell them at five thousand rupees each, which would have left a comfortable margin after accounting for selling costs of around two hundred rupees per unit.
Then the season ended earlier than expected. To clear the remaining stock, the retailer now expects to sell them at two thousand two hundred rupees per unit. Selling costs remain the same at two hundred rupees.
NRV in this case is two thousand rupees per unit. That is below the cost of three thousand rupees. So each jacket must now be recorded at two thousand rupees, and the difference of one thousand rupees per unit needs to be recognised as a loss.
Nobody wants to book that loss. But the loss already happened the moment the jackets stopped being sellable at cost. The write-down simply makes it visible on the financial statements where it belongs.
How It Affects the Financial Statements
When inventory is written down to NRV, two things happen.
On the balance sheet, the value of inventory falls. This reduces total assets, which in turn affects ratios like the current ratio and the overall asset base of the business.
On the income statement, the write-down appears as an expense, reducing profit for the period. This is why companies sometimes show inventory write-downs as a separate line item, because they can be significant enough to materially affect reported earnings.
If the circumstances that caused the write-down later reverse, and the NRV recovers, accounting standards do allow for a reversal of the write-down, but only up to the original cost. You can bring the value back up, but you cannot take it above what was originally paid for the inventory.
The Judgment Involved
One thing that makes NRV genuinely interesting from an accounting perspective is how much professional judgment it requires.
Estimating what inventory will sell for, and what it will cost to complete and sell it, involves assumptions about future market conditions, customer behaviour, and company capabilities. None of that is certain.
This means NRV calculations are an area where management has real discretion, and where auditors pay close attention. A company under pressure to report stronger profits might be tempted to use optimistic selling price estimates to avoid a write-down. A company trying to manage tax liabilities might do the opposite.
Reading the notes to financial statements carefully, particularly around inventory valuation policies and any write-downs recorded, tells you a lot about how conservative or aggressive a company’s accounting approach tends to be.
What to Focus on for Exams
When this topic comes up in an exam context, the questions usually test a few specific things.
The first is the basic formula itself. Selling price minus costs to complete minus costs to sell. Getting that right consistently matters.
The second is knowing when to apply it. The rule is always lower of cost or NRV, never higher than cost even if NRV is above it.
The third is understanding the direction of write-downs and reversals. Write-downs go through the income statement as an expense. Reversals are permitted but capped at original cost.
The fourth, and often the trickiest, is applying judgment in scenario-based questions where you are given a set of facts about inventory and need to decide what value it should be carried at.
Final Thought
Net Realisable Value is one of those accounting concepts that looks straightforward on paper but carries a lot of real-world weight behind it.
My father eventually started doing end-of-season clearances much earlier, once he understood that holding onto inventory at its original cost on paper did not change what the market would actually pay. The sooner he recognised the real value, the sooner he could make decisions based on accurate numbers.
That is really what NRV is about. Not punishing businesses for buying stock that later lost value, but making sure that when value has genuinely changed, the financial statements tell the truth about it.
