Dealership recon cost calculator.

Estimate how many vehicle-days are tied up by the gap between your current and target Time-to-Line, then apply your own daily holding-cost assumption. This is an operational planning model, not a profit guarantee.

DIRECT ANSWER

How do you estimate the cost of extra days in dealership recon?

A simple estimate multiplies monthly used-vehicle volume by the number of recon days you want to remove, producing vehicle-days saved. Multiplying those vehicle-days by the dealership's estimated daily holding cost gives an illustrative monthly holding-cost exposure associated with the T2L gap.

Used vehicles entering recon per month

Current Time-to-Line (days)

Target Time-to-Line (days)

Estimated holding cost per vehicle/day ($)

Use your own finance team's holding-cost assumption when available. The default $40/day is only an example starting point based on an NCM estimate reported by WardsAuto.

Recon days targeted for removal 4.0

Vehicle-days saved / month 240

Estimated monthly holding-cost exposure
                        ¤9,600

Illustrative annualized exposure
                        ¤115,200

Formula: monthly units x max(current T2L - target T2L, 0) x daily holding cost. This does not include depreciation assumptions, floorplan structure, gross, turn-rate effects, staffing, repair costs, or sales outcomes.

Benchmark context: WardsAuto reported an NCM Associates estimate of roughly $40 in daily per-vehicle holding cost in a 2019 article. Your actual cost can be materially different, so the calculator is intentionally editable. See the WardsAuto source.

What does the calculator actually measure?

The model is deliberately simple. It measures the difference between current and target recon days, multiplies that difference by monthly unit volume, and then applies a daily holding-cost assumption.

Vehicle-days

If 60 vehicles per month each spend four more days in recon than the target, that represents 240 vehicle-days per month before applying any dollar assumption.

That vehicle-day number is often the cleaner operational metric because it does not depend on a debated dollar estimate. A store can track whether it is reducing the amount of inventory time consumed before vehicles reach the frontline.

How to use the result

Use actual monthly used-vehicle recon volume rather than total lot inventory.
Calculate current T2L from consistent start and completion events.
Choose a target your operation can use for improvement planning.
Ask finance for the holding-cost assumption your store uses rather than relying on a generic benchmark.
Track actual stage dwell so the team knows which process change could remove the targeted days.

FAQ

Frequently asked questions

Concise answers to common dealership reconditioning questions related to this topic.

What is a vehicle-day in recon?

One vehicle-day represents one vehicle spending one day in the measured recon period. Sixty vehicles each spending four excess days in recon equals 240 vehicle-days.

Is the calculator estimating profit?

No. It estimates holding-cost exposure using the assumptions entered. It does not predict gross profit, sales volume, inventory turns, depreciation, staffing expense, or other financial outcomes.

Where does the default $40 daily holding-cost input come from?

It is an example starting point based on an NCM Associates estimate reported by WardsAuto. Dealerships should replace it with their own finance team's holding-cost assumption when available.

Should I use total used inventory as monthly units?

The calculator is designed around the number of vehicles entering recon per month. Using monthly recon volume keeps the vehicle-day calculation tied to the units moving through the process.

What if my target T2L is higher than my current T2L?

The calculator does not show negative savings. The modeled days saved are floored at zero.

How can Recono help after I calculate the opportunity?

Recono tracks active recon, vehicle aging, stage movement, throughput, and stage timing so the dealership can identify where the measured recon days are accumulating.
