How it is worked out
- Amount financed = price + tax − down payment − trade-in = $29,100.00.
- Payment = P × i ÷ (1 − (1 + i)^−n) with i = 0.00583333 and n = 60: $576.21.
- Fees, add-ons and how your state taxes trade-ins vary; enter only what applies to you.

How to use it
Amount financed = price + sales tax − down payment − trade-in. The monthly payment then follows the loan formula. $30,000 with $3,000 down, 7% sales tax and a 7% loan over 60 months finances $29,100 at about $576 a month.
Rules differ on whether trade-ins reduce the taxable price and on fees and add-ons, so enter the sales tax that applies to you and add fees to the price if you finance them. These are estimates from the numbers you type, not financial advice or an offer; real products add fees and change rates.
