How this is calculated

Monthly payment is calculated using the standard amortizing payment formula:payment = P × r × (1 + r)^n / ((1 + r)^n − 1), where P is amount financed, r is the monthly interest rate (APR ÷ 12), and n is the term in months.

Amount financed combines the vehicle price, sales tax, and fees, minus down payment, positive trade-in equity, and rebates. Negative trade-in equity (when you owe more than the trade-in is worth) is added to the financed amount.

Frequently asked questions

How is the monthly auto loan payment calculated?
We use the standard fixed-rate amortizing payment formula: payment = P × r × (1 + r)^n / ((1 + r)^n − 1), where P is amount financed, r is the monthly interest rate, and n is the number of monthly payments.
What is the amount financed?
Amount financed is vehicle price plus sales tax, fees, and any rolled-in negative equity, minus down payment, positive trade-in equity, and rebates. Tax basis varies by state.
Is this a guaranteed quote?
No. This is an estimate for educational purposes. Actual rates, taxes, fees, and approvals come from lenders and dealers.
