Estimate an auto transport quote range
Enter road miles and a base rate from a recent comparable quote or your budget. Change the visible percentages instead of relying on hidden market-rate assumptions.
Your inputs

Default worked example
The midpoint starts with 800 route miles at $1.05/mi, applies the selected adjustments, then shows a ±20% planning band.
How to use the calculator
Build a visible car-shipping planning range from entered road miles and a positive USD per mile assumption. Choose open or enclosed transport and running or non-running condition. Only active premiums apply; their values are retained when switching modes. Enter whole-percentage adjustments and a planning band from 0% to 95%.
What the result means
This is an input-based scenario before requesting carrier quotes. The band is a chosen scenario range rather than a confidence interval. Planning USD amounts display to whole dollars after exact decimal arithmetic; positive values below one dollar use three significant scientific digits so they do not appear free.
Formula and units
Base linehaul = road miles × entered USD/mile. Adjusted rate = base rate × (1 + active enclosed premium/100) × (1 + active non-running premium/100) × (1 + pickup adjustment/100). Midpoint = road miles × adjusted rate. Low/high = midpoint × (1 −/+ entered band/100).
Worked examples
Pickup-to-delivery road miles: 800 road miles; Base linehaul rate ($ per mile): 1.05 USD per road mile: Pickup-to-delivery road miles: 800 road miles; Base linehaul rate ($ per mile): 1.05 USD per road mile; Enclosed adjustment (%): 45 %; Non-running adjustment (%): 20 %; Pickup timing adjustment (%): 0 %; Planning range (±%): 20 %; Transport type: open; Vehicle runs, rolls, steers, and brakes?: yes.
Example result: Planning range: $672–$1,008; Midpoint: $840; Adjusted rate: $1.05/mi; Base linehaul: $840; Transport adjustment: 0%; Vehicle adjustment: 0%; Pickup adjustment: 0%; Distance: 800 mi.
Pickup-to-delivery road miles: 1200 road miles; Base linehaul rate ($ per mile): 1.58 USD per road mile: Pickup-to-delivery road miles: 1200 road miles; Base linehaul rate ($ per mile): 1.58 USD per road mile; Enclosed adjustment (%): 68 %; Non-running adjustment (%): 20 %; Pickup timing adjustment (%): 0 %; Planning range (±%): 20 %; Transport type: enclosed; Vehicle runs, rolls, steers, and brakes?: yes.
Example result: Planning range: $2,548–$3,822; Midpoint: $3,185; Adjusted rate: $2.65/mi; Base linehaul: $1,896; Transport adjustment: 68%; Vehicle adjustment: 0%; Pickup adjustment: 0%; Distance: 1,200 mi.
Limitations and common mistakes
Rates and premiums are entered assumptions, not live carrier prices. No carrier availability, pickup date, insurance coverage or final price is inferred. Confirm the terms in writing. Extreme scenarios whose modeled prices exceed the supported finite range are rejected. Inputs retain at most 64 decimal characters and exponents from -308 to 308.
Use road miles rather than straight-line distance. Do not apply an enclosed premium to open transport or a non-running adjustment to a running vehicle. Sequential percentage multipliers are not added together. The displayed range does not include unentered fees.

Car shipping cost calculator FAQ
How do I choose the base cost per mile?
Use a recent written quote for a comparable route, or enter your own budget assumption. CalculatorShelf does not supply a live market rate, and the final carrier price may include fees that a per-mile scenario does not capture.
Why is enclosed transport an adjustment instead of a fixed price?
The calculator starts with your base rate and applies the enclosed percentage you enter. Trailer availability, vehicle value, route, and season can move the real premium, so the percentage remains visible and editable.
What should I enter for a vehicle that does not run?
Select No and enter the percentage you want to use for additional loading effort. Tell the carrier whether the vehicle rolls, steers, and brakes because those details can affect equipment and price.
What does the planning range mean?
It is a sensitivity band around the calculated midpoint. A 20 percent setting shows a lower result at 80 percent of the midpoint and an upper result at 120 percent. It is not a confidence interval or a promised quote.
Does the estimate include taxes, storage, port, auction, or cancellation fees?
No. Add those separately when they apply. The model covers route miles and the visible percentage adjustments only.
How should I compare carrier or broker quotes?
Compare the total written price, pickup and delivery windows, open or enclosed service, cancellation terms, cargo coverage, and every named fee. Use the FMCSA licensing and safety lookups before booking interstate transport.
