Understanding Your Auto Loan
Principal & Interest
The principal is the amount you borrow to purchase your vehicle. Interest is the cost of borrowing that money. Early in your loan, most of your payment goes toward interest. Over time, more goes toward reducing the principal balance.
Down Payment Benefits
A larger down payment reduces your loan amount, monthly payment, and total interest paid. It also helps you avoid being "upside down" on your loan (owing more than the car is worth) and may qualify you for better interest rates.
Loan Term Considerations
Longer loan terms result in lower monthly payments but more interest paid over the life of the loan. Shorter terms mean higher monthly payments but significant interest savings. Consider what fits your budget and financial goals.
Trade-In Value
Your trade-in value reduces the amount you need to finance. However, if you owe more on your current vehicle than it's worth, that negative equity gets rolled into your new loan, increasing the total amount financed.
Making Extra Payments
Extra payments go directly toward your principal balance, reducing the total interest you'll pay and shortening your loan term. Even an extra $50/month can save hundreds or thousands in interest.
Save Money on Your Auto Loan
- Get pre-approved for financing before shopping to know your budget
- Compare rates from banks, credit unions, and dealer financing
- Consider certified pre-owned vehicles for lower prices with warranties
- Negotiate the car price separately from financing terms
- Make extra payments toward principal when possible
- Avoid extending loan terms beyond the vehicle's useful life
