Lease

To see a lease, pick a vehicle. A lease is priced on one car: what it is expected to be worth at the end (its residual) and the leasing company's money factor change by model and by month.

Pick a vehicleHow leasing works

An estimate on the numbers you type, not an offer of credit or a quote from any dealership. Starting loan rates are Rateous's rates for each credit range and term; they are not an offer from any lender. The documentary fee starts at an example figure, the state's legal cap where it has one or $599 where it does not, not any dealership's fee; each dealership sets its own. Taxes and state fees are estimates for Montana; the dealership's paperwork and your motor vehicle agency have the final numbers. Nothing you type is sent, saved, or used to check your credit.

How the tax works.

Montana has no state or local sales tax on vehicles.

Title fee $12.36 includes a 3% administration fee (MCA 61-3-111).

Annual registration is age-based rather than value-based, except for the $825 luxury surcharge and the county option tax.

Trade-ins: No sales tax, so no trade-in credit is needed.

Title, registration and fees.

On a $35,000 new car with a $37,000 sticker, registered in Billings, no trade-in: the same figures the calculator above uses. The dealership's documentary fee is its own and is not included.

Light vehicles (MCA 61-3-321): $217 per year if 4 or fewer years old, $87 for 5-10 years, $28 for 11+ years (permanent registration available at 11+).

Annual value-based tax: County option motor vehicle tax. Up to 0.7% of the depreciated value (MSRP times the statutory depreciation percentage) in counties that adopt it. Many counties impose it; the MVD fee estimator computes the exact amount.
