Inventory Turnover Benchmarks by Industry (2026)

Key facts

• Inventory turnover = cost of goods sold divided by average inventory. Days in inventory = 365 divided by turnover.
• Public consumer-product companies turn inventory 5 to 9 times a year on a sales basis (Damodaran, January 2026): apparel about 5.2, furniture and home about 5.5, consumer electronics about 7.3, household products about 8.7.
• U.S. retailers held 1.25 months of inventory relative to sales in June 2026, down from 1.30 a year earlier (Census Bureau, release CB26-132). Clothing stores held 2.14 months; furniture, home furnishings, electronics, and appliance stores held 1.59.
• Small ecommerce sellers usually turn slower than the public companies above, commonly 3 to 6 times a year, because they buy in larger minimum quantities and hold safety stock for long lead times.
• Every turn ties up cash from the supplier deposit to the platform payout, which can be four to six months. The calculator below shows that gap week by week.

What inventory turnover measures

Inventory turnover is how many times a year you sell through and replace your stock. It is the single ratio that connects three things sellers care about: how much cash is sitting on shelves, how much storage costs, and how fast the business can grow without new capital.

The standard formula is cost of goods sold divided by average inventory, both at cost. Average inventory is beginning inventory plus ending inventory for the period, divided by two. A seller with $500,000 in annual COGS and $100,000 of average inventory turns 5.0 times a year. Dividing 365 by the ratio gives days in inventory: 73 days in that example, meaning the average unit waits about ten weeks between arriving and selling.

Two things to keep straight when you compare your number with a benchmark. First, the basis. Public datasets often report inventory relative to sales rather than cost, which produces a higher turn than the COGS-based version; a sales-basis turn of 7 corresponds to a COGS-basis turn of roughly 4 to 5 for a business with a 35% to 40% gross margin. The tables below say which basis they use. Second, the period. A twelve-month average smooths seasonality; a single quarter does not, and a Q4 reading will flatter any gifting category.

2026 inventory turnover benchmarks by industry

The most consistent public benchmark is Aswath Damodaran's working capital dataset at NYU Stern, updated January 2026 from 5,994 U.S. public companies. It reports inventory as a percentage of sales by industry; dividing 1 by that figure gives a sales-basis turn, and dividing 365 by the turn gives days in inventory. Consumer-facing sectors relevant to ecommerce sellers:

Sector (public U.S. companies)	Firms	Inventory / sales	Sales-basis turns	Days in inventory
Retail (grocery and food)	15	5.5%	18.2	20
Retail (general merchandise)	23	8.7%	11.5	32
Household products	110	11.6%	8.7	42
Food processing	78	13.4%	7.5	49
Electronics (consumer and office)	8	13.6%	7.3	50
Recreation (sporting goods, outdoor, toys)	49	13.7%	7.3	50
Shoes	11	16.4%	6.1	60
Retail (distributors)	62	16.7%	6.0	61
Healthcare products	204	17.6%	5.7	64
Furniture and home furnishings	27	18.3%	5.5	67
Retail (special lines)	94	18.8%	5.3	69
Apparel	35	19.3%	5.2	70
Beverage (soft)	14	19.8%	5.1	72
Total market, all industries	5,994	8.0%	12.5	29

The Census Bureau's Manufacturing and Trade Inventories and Sales report gives a second, store-level view. It reports the inventory-to-sales ratio, meaning months of inventory on hand at the current sales pace. Figures are for June 2026, seasonally adjusted and preliminary, with June 2025 in parentheses.

Retail category (Census, June 2026)	Inventory / sales ratio	Sales-basis turns	A year earlier
Retail trade, total	1.25	9.6	1.30
Retail excluding motor vehicles and parts	1.08	11.1	1.13
General merchandise stores	1.24	9.7	1.27
Furniture, home furnishings, electronics, and appliance stores	1.59	7.5	1.57
Building materials and garden supplies	2.13	5.6	2.08
Clothing and accessories stores	2.14	5.6	2.19

Read together, the two sources agree on the shape of the market. Grocery and general merchandise turn fastest. Electronics, household goods, and recreation sit in the middle at about seven turns. Apparel, footwear, furniture, and specialty retail turn five to six times a year, with 60 to 70 days of stock on hand. Retail inventories overall got leaner between mid-2025 and mid-2026, with the total ratio falling from 1.30 to 1.25 months.

What these benchmarks mean for an ecommerce seller

The companies behind those numbers buy at scale, negotiate short lead times, and hold inventory close to demand. A brand doing $1 million a year on Amazon and Shopify usually cannot. Supplier minimums are larger relative to sales, overseas lead times run 45 to 90 days, and safety stock for a 14-day Amazon payout cycle or a Q4 peak adds weeks more. As a practical range, small and mid-size ecommerce sellers commonly turn 3 to 6 times a year on a COGS basis, and a well-run brand in a fast category can reach 8 or more.

A better target than any industry average is your own days of supply: supplier lead time, plus the days between order reviews, plus safety stock days. A seller with a 60-day lead time who reviews orders every two weeks and keeps three weeks of safety stock needs about 95 days of supply, which is 3.8 turns a year. That number is right for that seller even though the apparel benchmark says 5.2. If your turns are far below your own days-of-supply target, you have a stock problem. If they are far above it, you are probably running out.

What a turn costs you in cash

Turnover is a cash question before it is an efficiency question. Every purchase order starts with a deposit to the supplier, then the balance at shipment, then weeks of storage, and the money only comes back as the platform pays out after each sale. Slower turns stretch that cycle and increase the cash you need to fund the next order before the last one has paid for itself. The estimator below adds storage, shrinkage, and the cost of tied-up cash to a purchase order and draws the cash position week by week; put in your own lead time, sell-through, and platform to see where the low point falls.

How to improve inventory turnover

Sort SKUs by velocity and treat them differently

Most catalogs follow the same pattern: about 20% of SKUs produce 80% of revenue. Rank every SKU by units sold over the last 90 days and split the list into fast, medium, and slow movers (an ABC analysis). Fast movers get deeper stock and more frequent reorders. Slow movers get smaller orders, bundles, or a clearance plan. Anything that has not sold in 90 to 120 days, depending on category, is a candidate to discontinue rather than reorder.

Set reorder points from your own numbers

Reorder point = average daily sales, times lead time in days, plus safety stock. A product selling 10 units a day with a 14-day lead time and 7 days of safety stock has a reorder point of 210 units. Recalculate quarterly, and separately for peak season, because the same SKU can need three times the safety stock in October that it needs in February. The safety stock and reorder point calculator runs this for a peak-season order and shows the latest safe order date.

Match safety stock to turnover, not habit

Safety stock should be highest where turnover is high and lead times are long, because that is where a stockout costs the most sales. Low-turnover items with short lead times need almost none. Reviewing safety stock against actual turnover, SKU by SKU, usually frees cash without adding stockouts.

Shorten the supply side

Lead time is the biggest lever most sellers never pull. A second supplier closer to your market, a smaller minimum order in exchange for a higher unit price, or splitting a large order into two shipments all reduce the days of supply you must carry. On the payment side, ask for net-30 or a lower deposit; every day of supplier terms is a day of inventory you are not funding yourself.

Use promotions to move stock, not to move revenue

Bundling a slow SKU with a fast one clears stock without a straight markdown. Segmented email to past buyers converts better than a sitewide sale. When you do discount, know the depth at which the promotion stops growing profit: a 20% discount at a 35% margin needs roughly a 2.3x lift in units to break even on profit, and most clearance promotions do not get there. The peak-season planner names that break-even depth for your margin.

Watch inventory age monthly

A monthly report of units on hand by age band (0 to 30 days, 31 to 60, 61 to 90, over 90) catches problems earlier than the turnover ratio does, because the ratio is an average that a few fast SKUs can hide. Anything crossing 90 days on Amazon also starts to cost more, since aged-inventory surcharges and the Q4 storage rates apply on top of monthly storage.

Turnover and funding

Faster turnover is the cheapest working capital there is, and it is worth pursuing first. It also has a ceiling: at some point the next order is simply larger than the cash the last one has returned, especially ahead of a peak. That is the gap revenue-based funding is built for. Onramp Funds advances capital against combined sales across Amazon, Shopify, Walmart, BigCommerce, WooCommerce, Squarespace, Shopline, TikTok Shop, and Stripe, with a flat fee disclosed upfront and repayment as a percentage of daily sales, so a slow week repays less and a peak week repays more. Eligibility is $10,000 in monthly sales, six months of selling history, and a U.S. business entity, with no personal credit check. See how much capital your combined revenue unlocks.

Frequently asked questions

What is a good inventory turnover ratio for ecommerce?

Between 4 and 8 turns a year on a COGS basis is healthy for most physical product brands. Below 3, holding costs and tied-up cash start to erode margin. Above 10 in a category with long lead times usually means frequent stockouts.

Why do public company benchmarks look higher than my numbers?

Two reasons. Public datasets often measure inventory against sales rather than cost, which raises the ratio, and large companies buy in smaller relative quantities with shorter lead times. Compare your COGS-basis turn with the ranges for sellers of your size, and use your own days-of-supply target as the real benchmark.

How do I calculate days in inventory?

Divide 365 by your turnover ratio. A turn of 5 is 73 days; a turn of 8 is 46 days.

Does higher turnover always mean a healthier business?

No. Turnover that outruns your lead time means stockouts, lost rank on marketplaces, and paid traffic sent to out-of-stock listings. The goal is the turn that meets your delivery promise with the least aged stock.
