Key Takeaway: Most businesses only count what inventory cost to buy. Carrying cost is what it costs to keep. It's almost always bigger than people assume.
What's on This Page
What's Included in Carrying Cost
- Capital cost: the return you're giving up by having cash tied up in stock instead of somewhere productive
- Storage: warehouse rent, utilities, staff time to manage it
- Insurance: covering the value of stock on hand
- Shrinkage: theft, damage, and counting errors
- Obsolescence: stock that loses value before it sells
Example
A business holds $200,000 in average inventory. Industry-typical carrying cost runs 20-30% annually.
Why This Number Matters
Carrying cost is the hidden argument against overstocking. A "good deal" on bulk pricing can be erased entirely by a year of carrying cost on stock that didn't need to be bought that early. Use our Inventory Cost Calculator to run your own numbers.
Reducing Carrying Cost
- Buy closer to when you'll actually sell, using real forecasting instead of bulk-discount instinct
- Clear dead stock instead of letting obsolescence cost compound
- Improve counting accuracy to reduce shrinkage

Checklist
- List every cost category: capital, storage, insurance, shrinkage, obsolescence
- Estimate or calculate a dollar figure for each category
- Add them up as a percentage of average inventory value
- Compare that percentage to the 20-30% industry range
- Identify which single category is the largest contributor
- Set one concrete action to reduce that largest category
Common Mistakes
FAQ
What's typically included in carrying cost that people forget?
Cost of capital is the most commonly missed piece. Money spent on stock could have been used elsewhere, and that opportunity cost is a real part of the total.
Is 20-30% of inventory value a reliable number?
It's a widely cited industry range, but your actual number depends on storage cost, capital cost, and shrinkage specific to your business. Calculate your own rather than assuming the benchmark applies exactly.
How does carrying cost affect pricing decisions?
A bulk discount that looks attractive on paper can be partly or fully erased by a year of carrying cost on stock bought too early.
What's the fastest way to reduce carrying cost?
Clear dead stock first. It carries the same holding cost as good stock while contributing nothing to revenue.
