How fast is inventory turning?

MetricAnnual inventory turnover and its inverse expressed as weeks of forward cover

Unitturns per year, and weeks of cover

Two-axis chart: inventory turn ratio (left, higher better) and weeks of cover (right, lower better). Build from cost of goods sold divided by average inventory value, and inventory units divided by weekly run rate. Example: 6.2 turns per year, 8.4 weeks of cover (healthy for typical retail).

Online retail and DTC excluding grocery and perishables, blended verticals, 2025 to 2026 filings and platform data. Definition used: cost of goods sold divided by average inventory at cost. Weeks of cover derived as 52 divided by turns. · Turns computed on sales rather than COGS overstate the ratio by roughly the gross margin multiple, and this error is widespread in vendor benchmark posts. Compare only at cost. Category dispersion here is larger than in almost any other card in this section, running from about 1.3x in aftermarket auto parts to 20x in grocery and convenience, so a blended retail average is not usable. Public-company apparel filings cluster lower than DTC vendor benchmarks (Retail Dogma reports an apparel and footwear average of 3.99 turns against vendor ranges of 4 to 12), because public filings include store inventory and deeper assortments. GMROI, gross margin percent multiplied by turns, is the better single read because it prices the margin-versus-velocity trade rather than ignoring it.

The blended turns line looks acceptable while the weeks-of-cover distribution underneath it is bimodal, with a bulge of SKUs at under 2 weeks of cover (stocking out) and a long tail past 26 weeks (dead stock), so the average is describing a state no SKU is actually in.

Blended 5.1 turns against a category median of 4.5 reads fine, but 18% of SKUs sit under 2 weeks of cover and 31% of inventory value sits in SKUs past 30 weeks. Carrying cost on the tail alone is roughly 20% to 30% of that inventory value per year.

• Report turns at cost, never on sales, and segment by category, channel and vintage. A sales-based ratio overstates turns by the gross margin multiple, and a roll-up hides the bimodal distribution that actually needs the decision.
• Manage to GMROI rather than turns alone. Gross margin percent multiplied by turns puts a low-margin fast mover and a high-margin slow mover on the same scale, which is the only way to compare a 3-turn 60% margin category against a 12-turn 25% margin one.
• Set a hard markdown cadence by weeks of cover rather than by season calendar. Evidence across retail favours a single decisive markdown over successive small ones, which prolong the sell-through cycle and usually end deeper in total.
• Attack lead time and order frequency before attacking assortment depth. Brands running 8 to 12+ turns do so on short lead times and tight demand sensing, not on thinner ranges, and carrying cost at 20% to 30% of inventory value makes the freight premium on smaller, more frequent orders usually worth paying.
