Forty-six dollars in floor plan interest. Twenty dollars of manager time. Forty dollars of arbitration exposure. Look at any one of these per-vehicle costs in isolation and it's easy to wave off. Rounding error. Cost of doing business. Not worth the meeting.
That instinct is exactly why these costs stay invisible. They're individually small and collectively significant, and the only way to see the second part is to stop looking at one vehicle and start looking at a month.
So let's do that.
The per-vehicle stack
Start with a single vehicle on an $850 transport quote. The visible layers that stack on top of it:
- Transport invoice (quoted): $850
- Floor plan interest (8 days): +$47
- Auction storage: +$75
- Manager time: +$20
- Arbitration risk (expected): +$40
- True landed cost: $1,032
The quote said $850. The vehicle landed at $1,032 — about $182 in costs that weren't on the transport invoice. On one unit, $182 is forgettable. That's the trap.
Now multiply
Here's what that same $182 gap does once you run it across volume:
The per-vehicle number never changed. The only thing that moved is volume — and the annual figure went from "worth a look" to "worth a strategy." A 40-car-a-month dealer is carrying roughly $87,000 a year in costs that live on statements and invoices that never sit on the same page.
And this table only counts the layers on top of the quote. It doesn't include the broker's undisclosed margin folded inside the $850 — roughly $213 a vehicle that never reaches the truck, or another six figures a year at 40 units. Add the cut you were never shown and the volume lens gets even sharper.
Why volume is where the insight lands
The reason this is the view that tends to land for dealers isn't that the math is complicated. It's that the math is compounding — small per-unit costs don't stay small, they multiply, and the multiplier is your own throughput.
It also means the dealers with the most volume have the most to gain from seeing the stack clearly. If you move 100 vehicles a month, a $50 swing per unit — a faster average transit time, a tighter coordination workflow, direct carrier access instead of layered margin — isn't a $50 decision. It's a $60,000-a-year decision. Volume turns operational details into financial ones.
That's exactly how the biggest numbers get made. Cable Dahmer moves roughly 1,000 units a month and freed up more than $500,000 in a year by going direct; Baxter Auto Group pulled the broker layer out of all 20 of its stores and cut $55,000. Both were volume plays — a modest per-unit edge only became real money because they multiplied it across the lot.
See your own numbers, at your own volume
The fastest way past the abstraction is to put your real volume into the math. The calculator stacks all five layers — broker margin, floor plan interest, auction storage, manager time, and arbitration risk — and then scales them to your monthly and annual totals, so you see the compounding effect on your specific operation rather than a sample dealer's.
