Executive Summary
Carrying costs eat 20-30% of your inventory's value annually. See the hidden costs of poor inventory management and 6 ways CPG brands fix it.
What Does Poor Inventory Management Actually Cost?
More than you think, because most of the cost is invisible.
You see the obvious losses: expired product, damaged goods, the pallet of seasonal SKUs nobody bought. What you don't see is the compounding drag underneath.
Analyst firm IHL Group's 2025 research puts global inventory distortion, the combined cost of overstocks and out-of-stocks, at $1.73 trillion per year, or 6.5% of global retail sales. Supply chain disruption is the single largest driver at $301 billion, with tariff uncertainty now forcing brands into complex inventory positioning decisions.
That's not a big-retailer problem. Small and mid-sized CPG brands feel it harder, because they have less cushion.
Here's where the money actually goes.
The Five Hidden Costs Draining Your Margins
1. Carrying costs you never calculated
Storing inventory costs 20–30% of its value annually. Warehousing, insurance, taxes, depreciation, obsolescence, and the capital tied up in it.
Run the math on your own numbers. If you hold $200,000 in average inventory, you're paying $40,000–$60,000 a year just to let it sit. That expense never appears as a single line on your P&L. It's scattered across six accounts, which is exactly why nobody notices it.
2. Stockouts that quietly hand revenue to competitors
An empty shelf doesn't just lose one sale. It trains your customer to buy elsewhere.
For CPG brands selling through Amazon or retail, stockouts also damage search ranking and shelf placement. You pay twice: the lost sale today and the lost visibility tomorrow.
3. Dead stock masquerading as an asset
Your balance sheet calls unsold inventory an asset. Your bank account disagrees.
Dead stock consumes storage space, ties up capital, and eventually forces markdowns or write-offs. Every month you avoid dealing with it, the carrying costs compound.
4. A cash conversion cycle you can't see
Product businesses have a brutal timing problem: you pay for inventory months before it turns into revenue. Delays in production or shipping stretch that gap wider.
If you don't chart your cash conversion cycle, you're navigating that gap blind. That's when founders reach for fast, expensive funding, automated lenders with aggressive repayment terms and fine print that includes surprise liens. Poor inventory visibility drives desperate financing decisions.
5. Margins that vary wildly by channel and average out to mediocre
Amazon fees and storage costs eat margin differently than your Shopify store does. Wholesale plays by different rules entirely.
When you only look at blended margins, profitable channels subsidize losing ones. You keep stocking inventory for sales that lose money, and the numbers look fine in aggregate. They aren't.
Why Is Inventory Management Really a Financial Problem?
Because every symptom above traces back to visibility, not logistics.
The gap is measurable. IHL's 2025 data shows retailers with modern, data-driven inventory management achieve 2.3x higher sales growth and 2.5x higher profit growth than those running on guesswork.
Data-driven inventory management outperforms guesswork on sales growth and profit growth
| Metric | Guesswork (baseline) | Data-driven inventory management |
|---|---|---|
| Sales growth | 1.0x | 2.3x |
| Profit growth | 1.0x | 2.5x |

Brands with clean books know their true landed COGS. They know which SKUs earn and which drain. They know when the cash gap opens and how to plan around it. Brands without that visibility guess, and guessing at scale is expensive.
Software helps. But a dashboard can't tell you whether your Amazon channel is profitable after fees, or whether your supplier terms should be renegotiated, or whether that inventory loan is a lifeline or a trap. That requires financial expertise reviewing your numbers regularly.
How Do You Fix It? Start With These Questions
Ask yourself:
- What is my carrying cost as a percentage of inventory value?
- Which of my SKUs are actually my highest earners, net of all costs?
- What is my margin by channel, such as Amazon vs. D2C vs. wholesale?
- How long is my cash conversion cycle, and when does the gap peak?
- When did I last review supplier pricing and terms?
If you can't answer three of these in under a minute, your inventory is managing you.
