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

Kentucky taxes the car every year, not just at purchase
A recurring annual tax on the vehicle’s value applies here — assessed at 100% of value at a representative 1.25% rate. It never appears in a monthly payment and is easy to miss when comparing states.Kentucky assesses motor vehicles at 100% of value as of January 1, using the JD Power average trade-in value — there is no fractional assessment ratio. IMPORTANT: the 1.25% is the typical COMBINED total rate (state plus local), not the local portion alone, because a calculator needs the full rate. It is built as 0.45 (state) + 24.93 (median countywide total) + 54.70 (median school district) = about 124.6 cents per $100. The state component is fixed at 45 cents per $100 for non-historic vehicles. Local components vary widely — countywide totals roughly 15.2 to 44.1 cents and school rates 10.0 to 110.0 cents per $100, with city and special-district levies on top in incorporated areas — so real bills range meaningfully around this midpoint. Statutory downward adjustments exist for high mileage (max 40% off), branded/rebuilt titles (60% of trade-in value) and salvage titles (not over 25% of retail).
Local tax in Kentucky
Kentucky does not levy an ordinary sales tax on vehicles; it levies a 6% Motor Vehicle Usage Tax under KRS 138.450-138.470, paid to the county clerk at titling. There is no local add-on — 6% is the single statewide rate. Dealers are not required by statute to collect it; a buyer may pay the clerk directly. The base is 'retail price', which for a new vehicle is attested by notarised affidavit or, absent one, 90% of MSRP including standard and optional equipment and transportation charges, with manufacturer rebates NOT deductible from MSRP. LEASES are not taxed upfront: under the U-Drive-It provisions of KRS 138.463 a permit holder remits 6% monthly on gross lease charges, so a lease of 365 days or more is taxed payment-by-payment.
