Cost to move from Illinois to Montana
Moving cost: $950–$12,580
Moving about 1,400 miles from Illinois to Montana costs roughly $950 – $12,580, depending on how much of the work you hire out.
Distance between the states' population centers by road (estimate).
| Moving method | Typical range |
|---|---|
| Rental truck (DIY) Truck rental, taxes and fees. Add fuel, damage coverage, lodging and your time. | $950 – $4,210 |
| Moving container You pack and load; the company drives the container. | $1,800 – $4,690 |
| Full-service movers Loading, transport and unloading. Packing, storage and other extra services may cost more; confirm the written estimate. | $2,890 – $12,580 |
These ranges are based on summer (peak-season) quotes. A move between October and April usually costs less: peak prices run 20–30% higher.
A rental truck also burns about 140 gallons of fuel over this distance. One-way truck rental prices depend on direction: a truck headed where many people are moving often costs more than the same trip in reverse.
Ranges combine 198 published quote ranges on 22 interstate routes (moveBuddha, retrieved 2026-09-24) with 47 independent published prices from U-Pack, HireAHelper and Move.org, which raised the top of several ranges. They are not quotes; get at least three written estimates.
Alaska and Hawaii ranges come from published carrier rates and moving quotes, dated in each row (Matson's household-goods rates, U-Pack, Royal Hawaiian Movers). See how we estimate.
Shipping a car from Illinois to Montana
Car shipping: $1,030–$1,510
Shipping a sedan from Illinois to Montana on an open carrier costs about $1,030–$1,510, typically 3–7 days in transit over about 1,400 miles.
Modeled from 32 published 2026 route prices (SGT Auto Transport 'Ship a Car to Another State' sample routes, SGT Auto Transport cost calculator sample routes) plus published mainland-to-Hawaii and mainland-to-Alaska prices. Reverse ocean routes reuse those inbound prices as a proxy, not a separately sourced price for that direction. The 25% SUV and 35% enclosed-carrier uplifts are model assumptions; ocean carrier packages and vehicle charges can differ. Not a quote.
