Auto Parts inventory turnover.
Hub-and-spoke replenishment offsets a long-tail SKU profile to a 60-day cycle.
Where the 6.0x median comes from
The 6.0x figure is the cross-firm median for auto parts as of 2026-06-20, derived from U.S. Census NAICS source data. Top-quartile operators in this category clear 8.5x; the bottom quartile sits at 4.2x.
At the median, average inventory equals roughly 61 days of cost of goods sold. A business under bank-covenant review should compare its trailing-twelve-month ratio against this median first, then against the 8.5x top-quartile mark before setting a working-capital target.
Benchmark band
The band below plots a hypothetical 6.0x ratio against the industry axis. Colour bands flag whether a result is within fifteen percent of the median (caution), above it (healthy), or more than fifteen percent below it (risk).
Five-year trend
The auto parts median has moved from 5.4x in the earliest comparable year to 6.0x in the latest pull, a gradual lift of 0.6 turns.
How to use this number
- Pull trailing-twelve-month COGS and the matching average inventory balance from the GL.
- Compute your turnover with the calculator on the homepage. Select the Auto Parts benchmark.
- If your ratio is below 6.0x by more than fifteen percent, start the playbook at diagnose low turnover.
- If you sit above 8.5x, confirm stock-out frequency before declaring victory. See high vs low turnover.
