What Is Dead Stock?

Dead stock is inventory that has stopped moving - goods that no longer sell, parts that no longer get fitted, supplies nobody draws on - yet still occupy shelf space, tie up the money paid for them, and consume time in every count and audit. It is the quiet failure mode of inventory management: nothing dramatic happens, the stock just sits there while its value drains away.

One word, two opposite meanings. In business inventory, dead stock is a problem to be cleared. In sneaker, streetwear and fashion resale, “deadstock” is a compliment - brand new, never worn, still in the box. If that is the meaning you came for, skip to the other meaning. Everything else on this page covers the inventory sense: what it costs, how to measure it, how to find it, and how to get rid of it.

Dead stock in one sentence

Dead stock is inventory that has not been sold, issued or used within a threshold period you set - commonly 90 days for fast movers, 180 days for general supplies, or 12 months in the accounts - and is unlikely to move again at full value. It is stock still carried as an asset while behaving like a cost.

Two things follow from that definition. First, dead stock is defined by a threshold you choose, not by a law of nature: the same box of cable ties is healthy stock in one business and dead stock in another. Second, “dead” describes behaviour, not condition. Perfectly good, perfectly saleable items become dead stock simply by not moving.

How stock becomes dead

Dead stock rarely arrives as dead stock; it gets that way through a handful of recognisable routes:

• Over-ordering - a bulk discount or an optimistic forecast buys more than demand ever materialises for.
• Long lead times and minimum order quantities - when resupply takes weeks, buyers order big to be safe, and a supplier’s minimum order quantity can force a year’s worth of an item you use monthly. Both are rational decisions that manufacture surplus.
• Demand moved on - a trend faded, a client left, a project ended, and the stock bought for it stayed.
• Seasonal leftovers - what did not sell by the end of the season waits a year for its next chance, if it gets one.
• Superseded items - a new model, format, or standard makes the old one unwanted: cables for retired hardware, parts for machines you no longer run, branded material with the old logo.
• Range and variant sprawl - every extra SKU and near-duplicate variant is one more thing that can stall, and near-duplicates cannibalise each other until neither moves.
• Quality or design faults - a batch that works but nobody wants, or that failed a spec check and was quietly shelved instead of returned.
• Damage and expiry - stock that can no longer be sold or used at full value but was never formally dealt with.
• Kit that never came back into circulation - equipment recovered from a leaver or a closed project, put in a cupboard “for now”, and never returned to the pool.
• Poor records - items that “died” simply because nobody knew they were there; a duplicate order replaces stock that was on the shelf all along.

That last cause is the most fixable one, and it is why dead stock and inventory accuracy are so closely linked - stock that does not appear correctly in the records cannot be sold, used, or cleared on purpose. It also runs both ways: the same blind spot that hides stock you own causes the stockout that panics somebody into an oversized emergency order.

Dead stock vs slow-moving, excess and obsolete stock

These terms overlap and get used interchangeably, but they describe different problems with different fixes. The full ladder:

Three working phrases you will meet elsewhere. FSN analysis - fast, slow, non-moving - is the classification method behind the top three rows: you rank every item by movement frequency and treat each band differently. SLOB stands for slow-moving and obsolete stock, and E&O for excess and obsolete; both are shorthand finance and supply-chain teams use for the provision they hold against stock that is unlikely to sell.

The clearest single distinction remains the old one: dead stock describes behaviour, obsolete inventory describes a cause. All obsolete inventory is dead stock; not all dead stock is obsolete. The difference matters because the remedies diverge - dead-but-viable stock can be discounted or relocated, while obsolete stock is usually a write-off decision you are better off making sooner than later.

What dead stock actually costs you

“It ties up money” understates it. Dead stock charges you in at least seven ways at once:

• Frozen capital - the purchase price is already spent and is now unavailable for stock that would actually sell or get used.
• Storage and handling - rent, shelving, racking and the labour of moving it out of the way of things that matter.
• Insurance and risk - it is insured, it can be stolen, dropped, water-damaged or reach its expiry date, and every month on the shelf is another month of exposure.
• Value decay - superseded items keep losing worth while they sit. What would have recovered 60% at clearance last year may recover 20% now.
• Counting and audit time - every item costs time at each physical inventory count or cycle count, whether or not it has moved since the last one.
• Opportunity cost - the better item you did not buy, the supplier discount you could not take, the cash buffer you did not have.
• Reporting distortion - a healthy-looking total inventory figure hides the fact that a slice of it is unsellable, which flatters your working-capital position until somebody tries to convert it.

Carrying costs are often planned with a rule-of-thumb annual percentage of inventory value. Treat any such figure as a planning convention your own finance team should set from your actual rent, insurance and labour, not as a researched benchmark to copy.

The framing worth remembering: dead stock sits on the balance sheet as an asset while behaving operationally like a liability. It appears in the column that measures what you own, and shows up in daily life as something that costs you money to keep.

How to calculate dead stock

Two calculations cover most of what you need, and neither requires anything more than movement dates and unit costs.

Dead stock value = units with no movement in the period × unit cost, summed across every affected item.

Dead stock percentage = (value of non-moving stock ÷ total inventory value) × 100.

The percentage is the more useful of the two, because it is comparable over time. Resist the urge to chase a published target: an acceptable level differs sharply between fast-moving consumables and critical spares you hold on purpose. Track the direction of your own number quarter by quarter and investigate when it climbs.

Three surrounding metrics tell you what a snapshot cannot:

• Inventory turnover - how many times you cycle through stock in a period. A falling ratio is dead stock accumulating before it is old enough to be flagged.
• Days sales of inventory (DSI) = (average inventory ÷ cost of goods sold) × 365. The average number of days an item sits before it moves.
• Sell-through rate = units sold ÷ units received, over a period. Best for retail-style stock and seasonal buys, where a low sell-through at the end of the season predicts next year’s dead stock precisely.

A worked example. You bought 40 docking stations at €85 each for a laptop generation you have since replaced: €3,400 of frozen capital, none of it moved in the last twelve months. A clearance buyer offers €25 a unit, which recovers €1,000 and clears the shelf. If you instead write the batch off entirely, you recover nothing and still pay to dispose of it. If you can redeploy even 10 of them internally against machines still in service, you avoid buying 10 new docks at, say, €70 - so internal reuse is worth €700 here against a clearance value of €250 for the same 10 units. That comparison, not the sunk €3,400, is the decision. The numbers above are an illustration; run the same shape with your own unit costs.

How to find dead stock in your records

The defining signal is time since last movement. Turning that into a repeatable review takes five steps.

1. Make the movements exist. Every item needs a record with a stock level, and every movement - sale, issue, checkout, return, consumption, transfer - needs a date logged when it happens. Without dated movements, nothing below works, and you are back to walking the storeroom.
2. Set thresholds per item class, not one global number. Roughly: 90 days for fast-moving consumables, 180 days for general supplies, 12 months as the common accounting convention, and 12 to 24 months for spare parts and critical equipment where slow movement is deliberate.
3. Pull an ageing report. Bucket every item by days since last movement - 0-90, 91-180, 181-365, 365+ - with quantity and value beside each line. Value matters as much as age: fifty stalled cable clips are not the problem that three stalled machines are.
4. Split the 365+ bucket into three. Genuinely dead; deliberately held (insurance spares for equipment still in service, safety stock, regulatory minimums); and simply lost in the records. The third group is the interesting one - it is the same failure as a ghost asset or a zombie asset, where the register and the shelf have quietly stopped agreeing.
5. Assign an owner and a decision to every remaining line. Clear, redeploy, or consciously keep, with a name and a date against it. A review that ends in a report rather than decisions produces the same list again next quarter.

Run this on a schedule - quarterly suits most teams, monthly if stock turns fast - and give it a named owner. Dead stock discovered at the annual count is dead stock that has already had a year to lose value.

How to get rid of dead stock

Work down by recovery value, and stop at the first route that fits the item:

Internal redeployment is the route retail-focused advice skips, and it is often the best one for equipment, IT kit and spare parts. A dock that recovers €25 at clearance saves €70 if it replaces a purchase somewhere else in the business.

Two rules for the bottom of the table. Electricals, batteries and anything hazardous go through proper e-waste channels or an IT asset disposition process - the WEEE Directive sets the obligation in the EU, and “it went in the skip” is not a disposal record. And document every removal: an undocumented disposal is indistinguishable from a loss, and reappears at the next count as a stock discrepancy.

The worst option remains the default one - leaving it on the shelf, where it keeps costing storage space and audit time while its recoverable value falls.

Writing off dead stock: the accounting view

Inventory is carried at the lower of cost and net realisable value (NRV) - NRV being what you could realistically sell it for, less the costs of getting it sold. Once dead stock’s NRV drops below what you paid, the accounts have to catch up. Two mechanisms do that:

• Write-down - reduce the carrying value to NRV. The item still exists and still sits in the register; it is simply valued at what it is now worth.
• Write-off - remove it entirely, usually on disposal, taking the remaining book value as a loss. See asset write-off for the equivalent on the fixed-asset side.

Teams also meet the provision for obsolete stock (an allowance): a contra-inventory account that reduces gross inventory by an estimated amount without naming individual lines. It is how finance recognises that some percentage of stock will not sell before anyone has decided which pieces.

One framework difference is worth knowing. Under IFRS, IAS 2 allows a write-down to be reversed - capped at the original amount - if the reason for it ceases and NRV recovers. US GAAP treats an inventory write-down as permanent; the new, lower figure becomes the cost basis. Related concepts on the fixed-asset side are impairment and asset valuation.

Finally, a write-off is a records event as much as a finance one. If the item leaves the accounts but stays in the stock register or the asset register, it reappears at the next count and the whole exercise unwinds. Local rules and tax treatment vary considerably - this is a guide, not advice, and your accountant should sign off the treatment you use.

Preventing the next batch of dead stock

Prevention splits into four disciplines, and only the first is about buying.

Buying discipline. Order against a real reorder point rather than stockpiling. Keep safety stock deliberate and sized, not accidental. Buy small trial quantities of anything unproven, and treat bulk discounts and minimum order quantities as a cost to weigh rather than a saving to take - a 15% discount on four years of cover is not a discount. Where lead times are long, fix the lead time or hold a smaller planned buffer instead of one giant order.

Range discipline. Fewer SKUs and fewer near-duplicate variants means fewer things that can stall. Rationalising a range is usually cheaper than clearing the stock it generates.

Records discipline. Accurate stock levels prevent the duplicate purchase order that creates dead stock out of nothing. Log receipts at goods receiving, log issues when they happen, and rotate stock FIFO so the oldest units move first rather than ageing at the back of the shelf.

Process discipline. A scheduled slow-mover review with a named owner and a standing decision - clear, redeploy, or consciously keep - beats an annual discovery every time.

And one more for equipment-heavy businesses: lifecycle discipline. When a machine, vehicle or laptop generation is retired, review its consumables, spares and accessories in the same decision. Asset decommissioning that stops at the asset itself leaves a cupboard of orphaned parts behind.

Treat every batch of dead stock as evidence about a purchasing decision, not just a shelf to tidy. The list tells you which forecasts were wrong, which suppliers pushed volume you did not need, and which items should never be reordered.

Dead stock outside retail: equipment, spares and consumables

Most guidance on this topic assumes goods for sale. In an office, workshop, school, clinic or site business, dead stock looks different and hides better:

• Chargers, docks and cables for hardware that has been retired.
• Spare parts for machinery you no longer run.
• PPE in sizes nobody on the current team wears.
• Branded merchandise with the previous logo.
• Consumables bought for a project that ended.
• Kit that came back from a leaver and never went back into circulation.
• Licence seats still being paid for that nobody is assigned to.

Maintenance and MRO stores need one extra test. Some spares are held deliberately against a rare failure, and low movement is precisely the point - a €400 part that sits untouched for three years is doing its job if it prevents a day of downtime. So the question is not “has it moved?” but “is there still equipment in service that needs it?”. If the machine is gone, the spare is dead stock no matter how recently it was bought. If the machine is still running, low movement is insurance, and the ageing report should say so.

The habit that prevents most of this is pooled visibility: a shared equipment pool or tool crib with checkouts logged, so surplus in one department is visible to another before anyone raises a new order. Half of all internal dead stock is created by somebody buying a thing the business already owns.

Deadstock in fashion and sneakers: the other meaning

In sneaker and streetwear resale, deadstock means the opposite kind of thing. It describes an item that is brand new and never worn, with its original box, laces and tags intact - stock that “died” at the retailer and never reached a wearer. There it is a premium grade, not a problem, and it commands the highest price in a listing.

• DS (deadstock) - brand new, unworn, complete with original packaging.
• NDS (near deadstock) - worn a handful of times, minor signs of use.
• VNDS (very near deadstock) - worn once or twice, wear barely visible.

Fashion manufacturing borrows the word again for deadstock fabric: surplus mill or brand cloth resold and reused rather than discarded, now a common sustainability angle for small labels.

Same word, opposite sentiment. It is worth being explicit about which one you mean in a supplier conversation - “we have deadstock to move” reads as a fire sale to one audience and a premium listing to another.

FAQ

What is the difference between dead stock and obsolete inventory? Dead stock is the broader term: anything that has stopped moving, whatever the reason - it may still be perfectly sellable at the right price or in the right season. Obsolete inventory is dead for a structural reason: the product has been superseded, the part no longer fits anything you own, the format is discontinued. Obsolete stock rarely recovers and is usually written off; other dead stock can sometimes be discounted, bundled, or returned to the supplier.

How do you calculate dead stock? Two calculations do the job. Dead stock value is the units with no movement in your threshold period multiplied by their unit cost, summed across every affected item. Dead stock percentage is the value of non-moving stock divided by total inventory value, times 100. Track the percentage’s direction quarter by quarter rather than chasing a universal target, and read it alongside inventory turnover and days sales of inventory, which show flow rather than a single snapshot.

How long before inventory counts as dead stock? There is no universal rule, only conventions you choose per item class. Fast-moving consumables are commonly flagged after 90 days without movement, general supplies after 180 days, and 12 months without movement is the usual accounting default. Spare parts and critical equipment are often given 12 to 24 months, because slow movement is the whole point of holding them. Set the threshold by item class, not once for the entire store.

What are examples of dead stock? Chargers, docks and cables for a laptop generation you have retired; spare parts for machinery you no longer run; PPE in sizes nobody wears; branded merchandise carrying the previous logo; consumables bought for a project that ended; expired items in a consumables store; superseded media or connector formats; and licence seats still being paid for that nobody is assigned to. Outside retail, most dead stock sits in cupboards and stores rather than on a sales shelf.

How do you get rid of dead stock? Work down the list from highest recovery to lowest: return it to the supplier if your terms allow, discount it or bundle it with items that do sell, sell it through clearance channels or to liquidators, repurpose it internally as spares or demo units, donate it where that makes sense, and write off and dispose of what remains. The worst option is the default one - leaving it on the shelf, where it keeps costing storage space and audit time.

Why does “deadstock” mean something different for sneakers? In sneaker and streetwear resale, deadstock (often “DS”) flipped the meaning: it describes an item that is brand new, unworn, and usually in its original box - stock that “died” at the retailer and was never sold to a wearer. There it is a mark of value, not a problem. Fashion manufacturing uses “deadstock fabric” the same way, for surplus mill cloth resold rather than discarded. In business inventory contexts, dead stock keeps its original meaning of unsold goods consuming money and space.

The takeaway

Dead stock is anything that has not sold, been issued or been used within a threshold you set, and is unlikely to move again at full value. Measure it two ways - dead stock value in money, dead stock percentage as a trend - and read both alongside turnover and days sales of inventory. Find it with an ageing report bucketed by days since last movement, then split the oldest bucket into genuinely dead, deliberately held, and lost in the records. Clear it by recovery value, remembering that internal redeployment usually beats clearance for equipment and spares, and document every disposal so the accounts and the register end up telling the same story. Then treat the list as feedback: each line is a purchasing decision explaining itself after the fact.

Tools that make this easier

AMPthilly gives every item - physical equipment, consumables and digital records - one register entry with a status, a location, an owner and a full history of checkouts, returns and transfers, so “nothing has touched this since last spring” is something you can filter for rather than guess at. Per-asset stock levels, target stock, reorder point, unit price and price history sit on the same record, and the audit timeline and CSV export give finance the evidence behind a write-down or a disposal. Printable QR labels mean a scan with a normal phone camera opens the item’s profile in the browser, which is usually how forgotten stock gets rediscovered in the first place.
