Car Payment Calculator
Estimate a monthly auto-loan payment, total interest and total loan cost from vehicle price, down payment, trade-in, APR and term.
Calculation breakdown
What determines a car payment?
The amount financed is the vehicle price plus estimated sales tax and financed fees, minus your down payment and trade-in. The monthly payment then depends on APR and loan term. A longer term usually lowers the payment but increases total interest.
Frequently asked questions
Does a larger down payment lower interest?
It lowers the amount financed, which generally reduces both the payment and total interest.
Why include fees?
Dealer and registration-related charges can be financed and increase the loan balance.
Is the trade-in always applied before tax?
Tax treatment varies by jurisdiction; this calculator uses a simplified sales-tax estimate on vehicle price.
