Quick answer
For 800 road miles at an entered base rate of $1.05 per mile, open transport, a running vehicle, and flexible pickup, the midpoint is $840. A 20% planning band shows $672–$1,008.
The range changes when you select enclosed transport, mark the vehicle as non-running, add a pickup-timing percentage, or replace the base rate with a different comparable quote.
How to use the calculator
- Estimate pickup-to-delivery road miles. A mapping route is more useful than straight-line distance.
- Enter a cost-per-mile basis from a recent comparable quote or your own budget; the site does not provide a live market rate.
- Select open or enclosed transport and edit the enclosed adjustment if your comparison uses a different percentage.
- State whether the vehicle runs, rolls, steers, and brakes. Edit the non-running adjustment for the scenario you want to compare.
- Add a pickup-timing percentage only when modeling expedited or inflexible pickup.
- Use the range setting to see how sensitive the midpoint is to uncertainty, then compare the result with written total-price quotes.
What each result means
- Planning range: the midpoint reduced and increased by the range percentage you entered.
- Midpoint: base linehaul after the selected transport, vehicle-condition, and pickup adjustments.
- Adjusted rate: the effective per-mile rate after the same percentage adjustments.
- Base linehaul: route miles multiplied by the base rate, before adjustments.
- Adjustment cards: the actual percentages used for this run; an inactive choice shows 0%.
Decisions this calculator helps with
Compare open and enclosed transport
Keep distance and the base rate fixed, then switch trailer type to isolate the entered enclosed adjustment.
Price a non-running scenario
Model the added loading allowance separately and tell the transporter whether the vehicle can roll, steer, and brake.
Test pickup flexibility
Compare a zero-percent timing adjustment with the premium you expect for a narrower pickup window.
Prepare quote questions
Use the range to ask whether a written total includes storage, auction, port, fuel, oversized-vehicle, or cancellation fees.
What the estimate includes—and leaves out
The calculator includes route miles, an entered base rate, three visible percentage adjustments, and a sensitivity range. It does not pull carrier prices, rank providers, or predict a pickup date.
Real quotes can also reflect origin and destination access, seasonal demand, vehicle size and weight, operability, trailer availability, fuel, storage, port or auction rules, and a broker or carrier's contract terms. Add those costs separately when they are not already included in the base rate.
Car shipping estimate formula
Base linehaul = route miles × entered base rate per mile.
Midpoint = base linehaul × (1 + transport adjustment) × (1 + vehicle adjustment) × (1 + pickup adjustment).
Low end = midpoint × (1 − planning-range percentage).
High end = midpoint × (1 + planning-range percentage).
Open transport, a running vehicle, and flexible pickup each contribute a 0% adjustment in the default scenario. The enclosed and non-running percentages are editable assumptions, not claims about current market prices.
Assumptions and limitations
- Distance means expected driving miles between pickup and delivery, not straight-line mileage.
- The base rate comes from the user. It may already include some premiums or fees, so avoid adding the same cost twice.
- Percentage adjustments multiply; they are not simply added together. A 45% enclosed adjustment followed by a 10% pickup adjustment produces a 59.5% combined increase, not 55%.
- The planning range is a sensitivity band, not a statistical forecast, guaranteed price, or substitute for a written quote.
- Taxes, storage, port, auction, oversized-vehicle, inoperable-vehicle equipment, fuel, and cancellation charges are excluded unless represented in an entered assumption.
- Pickup and delivery dates, carrier availability, cargo coverage, deductibles, and damage-claim procedures are outside the cost calculation.

| Scenario | Calculation | Planning result |
|---|---|---|
| 800 mi, $1.05/mi, open, running, flexible pickup, ±20% | 800 × $1.05 | $840 midpoint; $672–$1,008 range |
| 1,200 mi, $0.85/mi, enclosed +45%, pickup +10%, ±15% | 1,200 × $0.85 × 1.45 × 1.10 | $1,627 midpoint; $1,383–$1,871 range |
| 500 mi, $1.15/mi, open, non-running +20%, ±10% | 500 × $1.15 × 1.20 | $690 midpoint; $621–$759 range |
Common mistakes when estimating car shipping cost
- Using straight-line distance instead of expected driving miles.
- Starting with a base rate that already includes enclosed or non-running service, then applying the same adjustment again.
- Treating a planning band as if it were a carrier's promised total.
- Leaving out vehicle size, storage, port, auction, fuel, or cancellation fees that appear separately in a contract.
- Comparing a broker's deposit with another quote's full transport price.
- Booking without confirming the USDOT or MC record, safety profile, cargo coverage, and damage-claim process.
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.
Sources and model boundaries
Official tools for pre-booking checks:
- The two FMCSA tools help readers examine registration and safety records; they do not provide the calculator's cost inputs.
- Cost basis: route miles and every price adjustment are entered or visibly set by the user.
- Range basis: a symmetric user-selected percentage around the calculated midpoint.
- Excluded factors: live market rates, route scheduling, fees not entered, and contract-specific coverage or claim terms.
- Calculation method: CAR_SHIPPING_ESTIMATE-1.1.
What usually drives the estimate most: the starting rate, route miles, trailer type, vehicle operability, pickup flexibility, and fees outside the model.

What to do next
Run open and enclosed scenarios with the same route, then collect written total-price quotes that name every fee. Look up the USDOT or MC record and safety profile, read the cancellation and cargo-claim terms, and keep the quote beside the calculator result. For freight dimensions, use the LCL shipping calculator or pallet calculator. If the arithmetic differs from the displayed formula, report an issue with the inputs and expected result.
