Beginner guide

Use the real price you expect to finance

The useful number is not only the sticker price. Taxes, fees, down payment, and trade-in value can change the loan amount a lot.

If the dealer rolls taxes or fees into the loan, include them here. If you pay them upfront, leave them out or reduce the financed amount.

  • Down payment lowers the loan amount immediately.
  • Trade-in value works like an extra credit toward the purchase.
  • A longer car loan can hide the cost by making the monthly payment look easier.

New car and used car are labels, not magic

The new/used choice helps keep the estimate organized. The payment still comes from price, rate, term, taxes, fees, down payment, and trade-in value.

Used cars may have different rates or fees, so update those inputs instead of relying on the label alone.

Formula

Loan amount = vehicle price + sales tax + fees - down payment - trade-in value. Monthly payment uses the standard amortizing auto loan formula.

Example

A $28,000 used car with $3,000 down, $2,000 trade-in, 6.5% tax, $600 fees, and 7.2% for 5 years has an estimated payment of about $503 per month.
