Your monthly payment depends on three main factors: the vehicle's price, your down payment (or trade-in credit), and the loan term (how many months you finance). A larger down payment or shorter loan term lowers your payment-but might feel tight month to month. A longer term spreads payments out, but you pay more in total interest.

A good rule of thumb: your total monthly vehicle costs (payment, insurance, fuel, maintenance) should fit comfortably in your budget. Most people aim for 10-15% of gross monthly income.
