# What Drives Your Monthly Payment

Your monthly payment is shaped by several factors working together. Understanding them helps you make smart financing choices.

## The Main Drivers

**Vehicle price** (what you're financing) is the biggest factor-costlier vehicles mean higher payments. **Down payment** reduces the amount you borrow, lowering your payment directly. **Interest rate** (APR) determines how much you pay beyond principal; better credit typically earns lower rates. **Loan term** (36, 48, 60, or 72 months) spreads payments over time-longer terms mean lower monthly payments but more total interest paid.

## Trade-In & Incentives

Applying a trade-in or manufacturer incentives toward the purchase price also lowers what you finance.

## Finding Your Payment

The right balance depends on your budget. Longer terms feel cheaper monthly but cost more overall. Larger down payments reduce monthly payments and total interest. Our finance team helps you explore scenarios.
