Arizona car loan calculator

Arizona charges a 5.6% state transaction privilege tax on most vehicle purchases. Arizona's state rate is usually combined with city and county taxes, so the total depends on where you live. Local Arizona taxes can be added on top of the state figure, so enter your combined rate in the tax field for a closer estimate.

Example: on a $36,000 vehicle with $5,000 down and a $2,500 trade-in, the state-level tax figure above adds about $2,016. Financing $30,516 at 7.25% APR for 60 months works out to roughly $608 per month and $5,956 in total interest. Change any field in the calculator above to match your deal.

State-level figures reviewed October 2026. Rates change and local rules differ, so treat this as an estimate and confirm with the Arizona revenue department or DMV. Compare every state on the car tax by state page.

Car buyers in Arizona should look beyond the advertised vehicle price. Tax, lender APR, dealer documentation charges, title costs, insurance, and registration can all affect the final monthly payment. Ask for an itemized out-the-door price so you know exactly what is being financed.

Use a conservative APR until you have a preapproval. Credit unions, banks, captive lenders, and dealer finance offices can quote different terms for the same vehicle. Comparing the total interest line helps you avoid choosing a loan that looks affordable only because the term is stretched too far.
