How the auto loan calculator works

Enter the vehicle price and the money you're bringing to the deal (down payment + trade-in value − amount owed on trade). The remaining balance is the amount financed. The calculator amortizes that balance over your selected term at the APR you entered, and shows the monthly payment plus lifetime interest.

Tips before you sign

  • APR matters more than any dealer add-on — a 1% APR drop on a $30k loan saves roughly $850 over 60 months.
  • 72 and 84-month loans lower your payment but compound interest significantly. Aim for 60 months or less when possible.
  • Negotiate the vehicle price first. Don't start with "what payment can I get?" — that invites rate and term padding.
