20% Inventory Carrying Costs: 2026 Data & Ways to Cut Them

If you hold $100,000 of inventory, the purchase cost on your supplier invoice is not the full cost of owning it. A widely used benchmark puts annual inventory carrying cost at about 20% of inventory value. That means the stock sitting on your shelves can cost roughly $20,000 per year before you sell it.

That figure is a benchmark, not a universal law. Your real number may be lower for fast-moving, compact products or higher for slow, bulky, seasonal, perishable, or highly financed stock. Carrying cost is real, recurring, and easy to miss when the only number you watch is product cost.

This guide breaks down the latest useful benchmarks, shows how to calculate your own carrying cost, and explains which inventory decisions reduce it without creating stockouts.

What is the average inventory carrying cost in 2026?

AccountingTools describes about 20% of inventory cost per year as a common carrying-cost benchmark. Its example reaches 17% after adding warehouse space, equipment depreciation, insurance, handling labor, damage, and interest. Read the AccountingTools explanation and example.

The range can be wider. Some inventory-management guides use 20% to 30% as a practical rule of thumb, but that is still only a starting point. Your real rate depends on financing, space, handling, service costs, and the risk profile of the products you hold. See the carrying-cost overview from Fit Small Business.

For a small product business, the practical takeaway is not that you should automatically add 20% to every SKU. You should calculate a rate using your own cost of capital, space, service expenses, and inventory risk.

The four pillars of inventory carrying cost

Carrying cost is easier to control when you stop treating it as one mysterious percentage. The standard breakdown has four parts: capital, service, storage space, and inventory risk.

1. Capital cost

Capital cost is the return your cash could have generated somewhere else. When you pay a supplier for stock that will sit for six months, that money is unavailable for marketing, hiring, product development, debt reduction, or your next purchase order.

This cost is often invisible because no separate invoice arrives. You still need to include it in the calculation. If your business uses a 10% annual cost-of-capital assumption and holds $100,000 of average inventory, the capital component alone is $10,000 per year. That is a worked example, not a universal rate.

2. Inventory service costs

Service costs include insurance, taxes, physical handling, and inventory-control work. The ASCM reference lists estimated ranges of 1%-3% for insurance, 2%-6% for taxes, 2%-5% for warehouse expenses, 2%-5% for physical handling, and 3%-6% for clerical and inventory-control work.

Your accounting treatment will differ by location and business structure. Include the labor and administration around stock, not just rent.

3. Storage space costs

Space is more than the monthly warehouse bill. It includes shelving, racks, equipment, utilities, security, and the opportunity cost of using a larger facility than you need.

Bulky products can have a high space cost even when their purchase value is modest. A slow-moving sofa, lighting fixture, or carton of packaging may consume the same floor area for months while contributing no cash.

4. Inventory risk costs

Risk costs include shrinkage, damage, deterioration, expiry, markdowns, and obsolescence. It is one part of carrying cost, but often the part that grows fastest when demand changes and aged stock is not reviewed.

Risk is where poor visibility gets expensive. If you do not know which SKUs are slow, you cannot intervene while the product still has resale value.

The chart shows the four cost buckets, not equal financial shares. Actual shares vary by product and business.

How to calculate your inventory carrying cost

Use this formula:

Carrying cost percentage = total annual carrying costs / average annual inventory value x 100

Start with the average inventory value, not the value on one unusually high month. A simple approach is to add your opening and closing inventory values and divide by two. A monthly average is better if your stock levels move sharply through the year.

Then total the costs that relate to holding that inventory:

• Cost of capital or financing
• Insurance and inventory-related taxes
• Warehouse rent, utilities, and equipment
• Receiving, put-away, counting, and handling labor
• Shrinkage, damage, expiry, and obsolescence
• Markdown or liquidation costs caused by aged stock

A worked example

Imagine a product business with $100,000 of average inventory:

| Cost category | Annual cost | Percentage of inventory | |---|---:|---:| | Capital tied up in stock | $10,000 | 10.0% | | Warehouse and equipment | $4,000 | 4.0% | | Insurance, tax, and service costs | $2,000 | 2.0% | | Handling and inventory control | $2,000 | 2.0% | | Damage and obsolescence | $2,000 | 2.0% | | Total | $20,000 | 20.0% |

This business is not paying one $20,000 carrying-cost bill. It is paying several smaller bills and losing money through tied-up capital and stock risk. That is why the number is easy to ignore.

What this means for your business

A 20% carrying-cost rate changes how you evaluate a purchase order. If you bring in $30,000 of extra stock and it sits for a year, the product has not merely occupied a shelf. Under the worked example rate, it has created approximately $6,000 of carrying cost before markdowns or lost resale value.

That does not mean you should always order less. Stockouts lose sales, damage customer trust, and can create expensive rush freight. The goal is not minimum inventory. The goal is enough inventory for the service level you want, with a clear reason for every buffer.

How to reduce inventory carrying costs in 2026

Improve demand forecasting before changing safety stock

Forecasting helps you separate repeatable demand from wishful thinking. Review sales history, seasonality, recent demand changes, supplier lead times, and stockout periods before setting reorder quantities.

A forecast is not a promise. It is a better starting point than ordering by instinct or copying last year's purchase order.

Set reorder points by SKU, not by habit

A single “keep two months of stock” rule is easy to remember and often wrong. Fast movers, slow movers, seasonal products, and long-lead-time items need different thresholds.

VNDLY can show stock projections with reorder points and stockout warnings, so you can see the likely timing of a shortage rather than discovering it after the shelf is empty. Its planning workflow also groups reorder suggestions by supplier and shows expected purchase cost, so the decision is connected to the next purchase order.

Find slow movers while they still have value

Create an aged-inventory review every month. Flag products with low recent sales, excess weeks of cover, no movement, or a falling margin. Possible actions include a bundle, promotion, supplier return, channel transfer, or liquidation.

Do not wait until a product is completely obsolete. By then, your options are narrower and the carrying cost has already accumulated.

Reduce counting and location errors

A stock record that says 40 units while the shelf contains 28 creates two problems. You may reorder too late, and you may believe you have sellable inventory that does not exist.

VNDLY supports stocktakes, multi-location inventory, and barcode and QR scanning through its mobile warehouse app. The scanner can be used for receiving purchase orders, stock counts, checking levels, and fulfilling orders. These workflows do not eliminate every error, but they make discrepancies easier to find and correct.

Review supplier lead-time performance

A supplier that regularly delivers late can push you into larger safety stocks. Track promised versus actual lead times, then use the result in purchasing decisions rather than relying only on the supplier's standard promise.

VNDLY includes supplier performance tracking and purchase-order history, so you can review delivery behavior alongside purchasing activity. For businesses with many vendors, that creates a more useful conversation than “the last shipment felt late.”

How VNDLY helps you see the cost earlier

VNDLY is built for product businesses that need inventory decisions connected to sales and purchasing. Relevant tools include:

• Stock projections: See expected stock levels and stockout timing using reorder points and demand signals.
• Demand planning: Compare forecast models and plan purchases before a shortage or excess becomes obvious.
• Purchase orders: Create, confirm, partially receive, and complete purchase orders while keeping expected receipts visible.
• Supplier performance: Review supplier lead times and purchasing history.
• Multi-location stock: See inventory by location instead of treating every unit as if it were in one warehouse.
• Reports and analytics: Export inventory, purchasing, product, supplier, and profitability data for review.
• Barcode and QR scanning: Count, receive, check, and fulfil stock from the mobile app.

Frequently Asked Questions

What is a normal inventory carrying cost percentage?

About 20% of inventory value per year is a commonly cited benchmark, but the right rate depends on capital cost, storage, service expenses, and inventory risk. Some businesses will be below it. Bulky, seasonal, perishable, or slow-moving inventory can be above it.

What is included in inventory carrying cost?

The main categories are capital cost, inventory service costs, storage space costs, and inventory risk costs. Risk includes shrinkage, damage, expiry, markdowns, and obsolescence.

How do I calculate inventory carrying cost?

Add your annual costs related to holding stock, divide that total by your average annual inventory value, and multiply by 100. Use an average inventory figure rather than one unusually high or low month.

Does reducing inventory always improve profit?

No. Reducing stock too aggressively can create stockouts, missed orders, rush freight, and unhappy customers. The aim is to remove unnecessary inventory while protecting the service level your customers expect.

How can inventory software reduce carrying costs?

It can improve visibility into stock levels, demand, reorder points, supplier lead times, aged inventory, and location balances. Better visibility does not make the decision automatically, but it gives you earlier evidence and fewer blind spots.

The bottom line

20% of inventory value per year is a useful carrying-cost benchmark. Your rate is built from cash tied up in stock, the space and labor needed to hold it, and the risk that some of it will be damaged, misplaced, or never sold.

Calculate your own rate. Review it by product group. Then use demand, lead-time, and stock-age information to decide where to reduce inventory and where a buffer is justified.
