Holding cost is everything it costs to keep an item in stock — capital tied up, storage space, insurance, and the risk of it becoming dead stock — commonly estimated at 15-30% of an item's value per year. Ignoring it makes overstocking look free when it isn't.
"It's already paid for, might as well keep it in stock" ignores that holding inventory has an ongoing cost, not just a one-time purchase cost.
What's actually in holding cost
- Capital cost: money tied up in stock that could be used elsewhere in the business
- Storage cost: the physical space, and what else that space could hold
- Risk cost: the chance the item becomes dead stock, damaged, or obsolete before it sells
- Handling cost: the ongoing labor of managing and counting stock that's just sitting there
A rough estimate
Holding cost is commonly estimated at somewhere between 15% and 30% of an item's value per year, depending on the business and category — meaning an item worth 10,000 sitting unsold for a year can genuinely cost 1,500–3,000 in holding cost alone, on top of the fact that it hasn't generated any revenue.
Why this changes reorder decisions
Ordering "a bit extra, just in case" feels safe, but a bigger buffer on every item compounds into a real, ongoing cost across your whole catalogue. Comparing that cost against the actual cost of occasionally running out (a lost sale, a delayed order) is a more honest way to size a safety buffer than defaulting to "more is safer."
Where it connects to reorder points and dead stock
Holding cost is the reason reorder points shouldn't be set arbitrarily high, and it's the reason dead stock is worth clearing rather than leaving on a shelf — both decisions are, underneath, about balancing holding cost against the cost of not having enough stock.

Is holding cost the same for every item?
No — high-value, slow-moving, or perishable items typically carry a higher effective holding cost than low-value, fast-moving ones.
How do I reduce holding cost without risking stockouts?
Tighten reorder points using better demand data (see our forecasting guide) rather than cutting stock levels arbitrarily — the goal is a buffer sized to real demand variability, not just a smaller number.
