A realistic car payment: this calculator includes sales tax, your trade-in, dealer fees, and your down payment — not just the sticker price.

How it works

  1. Input the sticker price of the vehicle along with expected dealer fees.
  2. Include your down payment and trade-in value to reduce the taxable amount.
  3. Enter the APR and term length to generate the accurate monthly payment schedule.

Frequently asked questions

Should I include the trade-in?

Yes — in most states the trade-in reduces the taxable amount, so it saves you tax as well as principal.

Is a longer term better?

It lowers the monthly payment but raises total interest, and increases the time you owe more than the car is worth.

What APR should I enter?

Use the rate from your pre-approval or lender quote. Advertised teaser rates often require top-tier credit.
