Dealership Inventory Aging: What Each Extra Day Costs

1. Choose an age clock that explains the delay

Start with a clear acquisition date and an as-of date. Also track when the vehicle arrived, became ready for sale and was first advertised. A vehicle acquired 45 days ago but ready for only 10 days needs a different discussion from one that has been advertised for the full 45 days.

Use calendar dates consistently in the location's time zone. Mark a missing acquisition date as unknown. A transfer between locations should not silently reset total time in stock. Keep each acquisition episode distinct so a returned or reacquired vehicle does not inherit the wrong clock.

2. Separate recorded investment from ongoing holding costs

Recorded vehicle investment may include acquisition and reviewed preparation costs. Financing, storage and other time-related costs require their own evidence and definitions. Do not apply an assumed interest rate to the entire purchase price when only part of the vehicle is financed.

The relationship is commercially meaningful. In its May 14, 2025 first-quarter release, AutoCanada attributed lower floorplan financing expenses partly to reduced new and used inventory levels and lower interest rates. That is one company's dated experience, not a benchmark or forecast for an independent dealership.

3. Calculate a holding-cost scenario

A fictional vehicle has a $22,000 acquisition cost and $1,000 of recorded preparation costs. Its recorded investment is $23,000. Assume $20,000 remains financed at a constant 8% annual rate for 45 days, using a basis of 365 days.

Assumed storage of $1.50 per day adds $67.50. The scenario's selected holding costs total $264.76. A $24,000 sale would leave $1,000 above the recorded investment, or $735.24 after these selected holding costs, before other selling costs and overhead.

This is a management scenario. Actual financing can involve changing balances, fees, subsidies and another day-count basis. Keep actual charges and estimates separate, and avoid counting an already recorded financing charge again. A management holding-cost estimate does not determine the vehicle's accounting carrying amount. For businesses reporting under IFRS, inventory measurement follows IAS 2's cost and net realisable value requirements.

4. Review the oldest stock with its readiness and demand

Use a weekly table with stock identifier, acquisition date, days held, ready date, asking price, recorded investment, financing balance, recent inquiries and next action. Add cost completeness and source date so a precise-looking amount does not hide missing preparation invoices.

Possible actions include completing preparation, checking the advert, reassessing comparable vehicles, changing the sales approach or reviewing a wholesale offer. Document the reason and owner. An illustrative 30, 60 and 90 day review policy is a workflow choice, not a universal industry standard.

5. Keep the decision tied to its source

Retain the source stock export, cost records and assumptions used in the review. Recheck them before acting. Faster turnover can support liquidity, but an immediate sale at any price is not automatically the best outcome. BDC distinguishes inventory from more liquid current assets when discussing working capital.

In Vanteloq, dealership review starts with reviewed DMS stock CSV exports and dealership records. Aging and recorded investment depend on those inputs and the loaded stock view's coverage. Eligible stock with complete posted costs includes an offer-versus-waiting comparison. Enter the current offer, assumed future price, additional daily holding cost and waiting time. The scenario keeps estimates separate from posted costs and does not record a sale or change the books.
