Buying a car in Utah
Every figure below is sourced to Utah’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.

Local tax in Utah
The 4.85% here is the STATE-imposed portion: 4.70% state sales and use tax plus 0.15% State Medicaid Expansion. Two local components apply in EVERY Utah jurisdiction — 1.00% Local Sales and Use Tax and 0.25% County Option — making 6.10% the statewide minimum; cities, counties, transit and special districts layer more on top. Which location governs: a dealer sale uses the DEALER'S location, a non-dealer purchase the BUYER'S registration address. SEPARATELY, Utah levies an annual age-based UNIFORM FEE in lieu of property tax, paid at registration and each renewal. It does not fit the ratio/mill-rate model — it is a flat-dollar bracket table by age: 0-2 years $150, 3-5 $110, 6-8 $80, 9-11 $50, 12 or more $10. A separate 1.5% fee on fair market value applies to medium/heavy trucks and larger vessels, not to passenger cars.
