Understand what you are actually reducing
Carrying cost breaks into four components: capital cost (the opportunity cost of cash tied up in stock), storage cost (warehouse space, utilities, handling), insurance and tax (based on inventory value), and risk cost (obsolescence and shrinkage). Reducing carrying cost overall means addressing whichever components are largest for your business rather than assuming one universal fix covers all four.
A business with expensive warehouse space benefits most from reducing physical stock volume; a business with a high obsolescence rate benefits most from clearing slow-moving stock faster. Diagnosing which component dominates your carrying cost focuses effort where it actually pays off.
Right-size order quantities
Ordering in large batches to get better unit pricing or reduce ordering frequency increases carrying cost, since more stock sits longer before selling. Calculating an economic order quantity (EOQ) balances ordering cost against carrying cost explicitly, rather than defaulting to round-number order quantities that may be larger than optimal.
For fast-moving items with reliable, short supplier lead times, smaller and more frequent orders often reduce total carrying cost even after accounting for slightly higher per-order costs, since less capital sits idle in stock at any given time.
Right-size safety stock
Safety stock exists to absorb demand and lead-time variability, but oversized safety stock especially a flat buffer applied across every SKU regardless of actual variability directly inflates carrying cost without a proportional reduction in stockout risk. Calculating safety stock per SKU based on that item's actual demand variability and lead time, rather than a one-size-fits-all rule, keeps the buffer proportional to genuine risk.
Periodically review safety stock against actual stockout history: a SKU with a large buffer that has never come close to triggering a stockout in over a year is very likely over-buffered and tying up more capital than necessary.
Clear dead and obsolete stock regularly
Carrying cost compounds the longer stock sits unsold dead and obsolete inventory generates ongoing capital, storage, insurance, and risk cost every month it remains on the shelf, on top of having already lost most of its resale value. Regularly identifying dead stock (no meaningful sales in a defined window) and obsolete inventory (discontinued or superseded items) and moving to clear them through discounting, bundling, liquidation, or write-off prevents this from silently growing.
Waiting for an annual review to discover accumulated dead stock means carrying its full cost for the entire period it went unaddressed. A more frequent review cadence catches and clears it faster, limiting how much carrying cost accumulates before action is taken.
Improve inventory turnover
Faster inventory turnover directly reduces average inventory value held over a period, which reduces every component of carrying cost proportionally. Improving turnover generally comes from better demand forecasting (avoiding over-ordering in the first place), more accurate reorder points (avoiding both stockouts that trigger emergency overordering and excess buffers), and pruning slow-moving SKUs from the catalog where they no longer justify the space and capital they occupy.
Reduce storage and risk costs directly
Beyond reducing the volume of stock held, storage cost itself can be reduced through better warehouse slotting (denser, more efficient use of existing space) or renegotiating storage costs if using a third-party warehouse. Risk cost (shrinkage) responds to the same controls covered in shrinkage prevention: barcode scanning to reduce administrative error, and appropriate physical security for theft-prone categories.
