Buying a car in Wyoming
Every figure below is sourced to Wyoming’s own revenue or motor vehicle publications and dated. Estimates only.
Auto loan calculator
The real out-the-door number — including whether your state credits your trade-in against the sales tax.
Auto lease calculator
Money factor, residual, and the payment — taxed by your state's actual method, since some states tax a lease's full value upfront instead of each payment.
Loan payoff calculator
What paying extra actually saves you — in interest and in months — on a car loan, a personal loan, or anything else that amortizes.
0% APR vs. cash rebate
Which dealer offer actually costs less over the life of the loan, and the rate at which they tie.
Personal loan calculator
Payment, total interest, and the effective APR once an origination fee is deducted from what actually reaches your account.
Debt consolidation calculator
Whether one loan actually beats paying your existing debts off as they are — measured against the best you could do without consolidating.
Auto refinance calculator
Whether refinancing your car loan is worth it — including whether a lower payment is being bought with a longer term on a depreciating asset.
Lease vs. buy a car
The same car both ways over the same months, with the resale value credited to the buyer — the part most comparisons leave out.

Wyoming taxes the car every year, not just at purchase
A recurring annual tax on the vehicle’s value applies here — assessed at 60% of value at a representative 3% rate. It never appears in a monthly payment and is easy to miss when comparing states.SCHEMA FIT CAVEAT — read before using. Wyoming's recurring annual vehicle tax is the county registration fee under W.S. 31-3-101(a)(i), computed as 3% of a declining percentage of the vehicle's FACTORY PRICE (original MSRP plus special equipment), not of current market value. The 60% here is the first-year figure; the statutory schedule runs 60%, 50%, 40%, 30%, 20%, then 15% from the sixth year on, each multiplied by 3% or $5.00 whichever is greater. So a first-year vehicle effectively pays 1.8% of MSRP, falling to 0.45% from year six. The 3% is a uniform statutory rate statewide rather than a locality-set mill rate, despite being called a county fee, and it is separate from and additional to the $30 state registration fee.
Local tax in Wyoming
A 4% state sales/use tax, collected not by the dealer but by the county treasurer before first registration. Counties may add a 1% general purpose option tax and a 1% specific purpose option tax, so combined rates run 4% to 6%; a few counties add an economic development tax of 0.25% to 0.5%, and two resort districts (Teton Village, Grand Targhee) add 2% for vendors physically inside them, reaching 8%. Rates move as county options are voted up or down. For calculation: documentary/dealer fees, incoming freight, accessories, preparation and handling, and standard warranties are INCLUDED in the taxable price; titling and licensing fees, outgoing freight and extended warranties are excluded. Payment is due within 65 days of purchase.
