Key takeaways
- Prices come from a pricing algorithm, not a number out of thin air.
- Formula: distance × per-mile rate + size + transport type + tier + demand multiplier.
- Per-mile rate decreases with distance and fluctuates with demand.
- Guaranteed pricing locks your rate at booking regardless of market shifts.
Car shipping prices are not random numbers. They're calculated by pricing algorithms evaluating distance, vehicle dimensions, route demand, carrier capacity, seasonal patterns, and current market conditions. Understanding how these factors combine helps you predict costs, time your shipment strategically, and recognize when a quote is too good to be true.
The pricing formula
At its simplest: Base Rate = Distance × Per-Mile Rate + Vehicle Size Adjustment + Transport Type Premium + Service Tier Premium + Demand Multiplier
The per-mile rate isn't fixed — it decreases with distance (economy of scale) and fluctuates with demand. A 500-mile shipment in September might run $0.85/mile. The same route in January might cost $1.10/mile because snowbird demand has absorbed carrier capacity.
Why quotes change over time
Market conditions shift daily. A Monday quote and a Thursday quote can differ because carrier availability changed, a demand spike happened, or seasonal patterns shifted. Guaranteed pricing (like ShipCargo's) locks your rate at booking regardless of subsequent market changes.
How to recognize a too-good-to-be-true quote
If a quote is 20–30% below the rest, it's a sales tactic. The broker will book you, then come back asking for more money once no carrier accepts the route. Real pricing reflects real market rates.
