How to Reduce Excess Inventory Without Killing Sales (2026)

To reduce excess inventory, first quantify it: excess equals current average inventory minus the inventory a target turnover ratio would require, which is annual COGS divided by that target. A business with $600,000 of COGS holding $120,000 of stock against an 8x target should hold $75,000, so $45,000 is excess. Naming the dollar figure changes the conversation from a general sense that there is too much stock to a specific amount of cash to recover, and it tells you when to stop cutting.

Step One: Size the Excess and the Cost of Holding It

Holding costs are commonly planned at 20% to 30% of inventory value a year, covering warehousing, insurance, shrinkage, obsolescence, and the financing cost of the tied-up capital. On $45,000 of excess that is $9,000 to $13,500 a year of pure carry, before counting the opportunity cost of what else the cash could do. Compute the figure once and it becomes the budget you are allowed to spend on fixing the problem.

The Four Levers, In the Order They Pay Back

1. Stop reordering the slow tail. Rank every SKU by days on hand and freeze replenishment on anything above twice your average. This is free, immediate, and reverses the inflow before you touch the existing stock.
2. Cut order quantity and raise order frequency. The economic order quantity formula balances the fixed cost per order against the cost of carrying the stock: EOQ = the square root of (2 x annual demand x cost per order ÷ annual holding cost per unit). Most overstock comes from chasing a volume discount that never covered the carry.
3. Improve the forecast on A items only. Weighted historical demand plus a seasonality factor beats intuition, and concentrating the effort on the 20% of SKUs carrying most of the value gets most of the benefit for a fraction of the work.
4. Liquidate what is genuinely dead. Mark down, bundle with fast movers, sell to a liquidator, or donate. Recovering 40 cents on the dollar today usually beats recovering 20 cents in eighteen months while paying carry the whole time.

ABC Classification Decides Where the Effort Goes

Classify SKUs by annual consumption value: A items are roughly the top 20% of SKUs carrying about 80% of value, C items the bottom 80% of SKUs carrying about 20%. Count and forecast A items tightly, review B items periodically, and move C items to vendor-managed or just-in-time replenishment where a supplier will carry them. Applying the same control effort to every SKU is how businesses end up counting screws as carefully as engines.

                Annual COGS                            = $600,000
Current average inventory              = $120,000
Current turnover = 600,000 / 120,000   = 5.0x  (73 days)
Target turnover                        = 8.0x  (46 days)
Target inventory = 600,000 / 8.0       = $75,000
Excess                                 = $45,000

Holding cost avoided at 25%            = $11,250 / yr
Slow tail (above 146 days on hand)     = $28,000 at cost
  liquidated at 45% of cost -> cash    = $12,600
  write-down recognized                = $15,400
Remaining $17,000 cut by smaller reorders over 2 quarters
              

The tax treatment of that write-down is worth getting right. For most taxpayers the IRS limits a deduction for donated inventory to its cost basis rather than its retail value, so donating dead stock and selling it to a liquidator often land in a similar place economically — the donation route trades cash recovery for a deduction. Whichever you pick, the write-down only becomes deductible when the goods are actually disposed of or the value is genuinely realized, not when you decide the stock is bad.

Keeping It From Coming Back

• Set a days-on-hand ceiling per SKU class and make it a purchasing rule rather than a review topic.
• Require a written justification for any order that pushes a SKU past that ceiling, including volume-discount orders.
• Review the slow tail monthly, not annually — obsolescence compounds quietly.
• Report inventory as days on hand rather than dollars, because the dollar figure looks reasonable right up until sales slow.
