Inventory Days Benchmark — Wholesale & Distribution

How many days of inventory does a typical Wholesale & Distribution business hold? This page tracks the listed companies in this segment — inventory days (DIO), the spread between the fastest and slowest quartile, and where Australian and American peers diverge, built from company filings, not survey responses.

By listing venue

Published separately because the two panels aren't measuring the same thing until a venue clears a minimum of four reporting peers — below that, a "median" is an anecdote, not a benchmark.

Each row is that company's own latest reported fiscal year — not all companies report on the same calendar, so years vary by row.

What this means

Distributors exist to hold the inventory so their customers don't have to — a plumbing wholesaler like Reece or an auto-parts distributor like Bapcor carries thousands of SKUs precisely so a tradesperson or workshop can get a part same-day rather than carrying that stock themselves. That's why inventory days sit meaningfully higher here than in retail: the buffer function is the business model, not a sign of poor turnover.

How this is calculated

Inventory days (DIO) is calculated as 365 × average inventory ÷ COGS, with the balance averaged against the prior year where one exists so a single year-end stock date can't distort the figure. US figures come from each company's own 10-K, pulled from the SEC's XBRL company-facts API. Australian figures come from each company's statutory accounts as rendered by Yahoo Finance, linking through to the company's ASX page — a weaker chain of custody than the US half, one step removed from the primary filing rather than pulled from it directly. Australian coverage runs three benchmark years (2022–2024) against eight for the US, because only a handful of fiscal years of ASX data are obtainable this way.

If your inventory days sit in the top quartile, that gap is cash.
