How to use this calculator

How auto financing is built

An auto loan is shaped by more than just the sticker price. Incentives, down payment, trade-in equity, sales tax, title fees, and whether those costs are financed all affect the payment and total cost.

  • Use Total Price mode when you already know the vehicle price and want to estimate payment, tax, interest, and total ownership cost.
  • Use Monthly Payment mode when you have a target monthly budget and want to work backward to a supportable vehicle price.
  • Review the amortization schedule together with the loan breakdown if you want to see how interest declines and principal repayment accelerates over time.

FAQ

Common Auto Loan questions

Should taxes and fees be included in the loan?

If taxes and fees are financed, the loan amount and interest cost both increase. If they are paid upfront, the monthly payment is lower, but more cash is required at purchase.

How does negative trade-in equity affect the auto loan?

If the amount owed on the trade-in is higher than the trade-in value, that negative equity effectively increases the financed balance and raises the monthly payment.

What does Monthly Payment mode do?

It works backward from a monthly budget to estimate the vehicle price and financed amount that fit the loan term, rate, tax, fees, incentives, and trade-in values you enter.
