Auto parts sales per average store measure revenue productivity relative to the retailer's average store base.

O'Reilly reported $2.811M of trailing-12-month sales per weighted-average U.S. and Puerto Rico store at June 30, 2026, up from $2.672M. AutoZone reported $2.593M per average store for fiscal 2026 versus $2.523M.

Store productivity separates unit economics from footprint growth

Total sales can rise simply because a retailer opens more locations. Sales per average store asks how much revenue the existing and newly weighted footprint generates per unit.

That makes it useful beside professional sales and DIY demand, which can change the productivity of the same physical store network.

Weighted-store definitions matter

O'Reilly excludes jobber sales and weights domestic stores based on approximate opening, acquisition, or closure dates. AutoZone uses its own total-company average-store methodology.

The levels should therefore not be ranked mechanically. Geography, store size, commercial penetration, and accounting scope differ.

Use sales per average square foot when store-size differences are material, and use store-level sales as a productivity bridge rather than a substitute for comparable-store growth.

Connect DIY and professional demand with commercial-service coverage, hub and distribution-center parts availability, inventory intensity and turnover, vendor funding, and store-level sales productivity.

Where this concept fits
  • DIY, professional, and store productivityCurrent relationship
    DIY sales and professional sales separate the two main customer jobs served by the auto-parts store network. Sales per average store and sales per average square foot show how that customer mix converts into unit and space productivity without replacing comparable-store growth.

  • Commercial coverage and parts-availability network
    Commercial program count shows how much of the store base can directly serve professional accounts, while hub stores and distribution centers position broader assortments at different points in the replenishment network. The counts are architecture inputs, not standardized service-quality scores.

  • Inventory intensity, turnover, and vendor funding
    Inventory per store shows local working-capital intensity, inventory turnover shows how quickly cost of goods sold cycles through average inventory, and accounts payable to inventory shows how much supplier credit offsets the inventory balance. Together they frame the tradeoff between parts availability and capital efficiency.
