Days on Lot

Days on lot (sometimes called days in inventory) counts how many days have elapsed between when a dealer acquired a vehicle and today — or the day it sold. A vehicle acquired on January 1st that sells on January 31st had 30 days on lot.

The metric is tracked both at the individual vehicle level and as an average across the entire inventory. Average days on lot tells you how fast your inventory is turning — a critical indicator of business health.

Every day a vehicle sits on your lot costs you money, even if nothing obviously bad is happening. Dealers with floor plan financing pay daily interest on unsold vehicles. All dealers face opportunity cost — capital tied up in a slow-moving vehicle cannot be used to buy a faster-moving one.

Vehicles also depreciate over time, independent of market conditions. A vehicle that has been on your lot 90 days has both lost value through time-based depreciation and is now competing against fresher inventory. The longer a vehicle sits, the more aggressive the eventual price reduction needs to be.

For independent used car dealers, an average days on lot of 30 to 45 days is a healthy target. Under 30 days can indicate underpricing — you may be leaving margin on the table. Over 60 days as an average means something systematic is off: pricing, photo quality, listing distribution, or inventory mix.

Most experienced dealers use milestone-based action plans: a price review at day 30, additional marketing (social post, reduced price) at day 45, and aggressive repricing or wholesale consideration at day 60. The goal is to prevent any vehicle from reaching 90 days without a deliberate decision to hold it.
