How this calculator works
A car loan is secured by the vehicle. The amount financed is the price, less any down payment and trade-in credit, plus sales tax on the taxable difference.
Amount financed = price − down payment − trade-in + sales tax, where sales tax = (price − trade-in) × tax rate.
Then Payment = P × i ÷ (1 − (1 + i)−n).
- P — the amount financed
- i — the monthly rate (annual rate ÷ 1,200)
- n — the number of monthly payments
When the down payment and trade-in cover the price and the tax, nothing is financed and the payment is zero.
Sales-tax rules differ by state and locality, and auto rates follow credit and term, so enter your own numbers.
