Auto Loans

Down Payments, Loan Terms, and Depreciation
Car loans can be confusing because dealerships often focus on the monthly payment rather than the total cost. When discussing a monthly payment with a dealer, they can make almost any car appear affordable by extending the loan term.

Let’s use a $30,000 car as an example:
  • A 48-month loan would be ~$690 per month, ~$3,000 in total interest
  • An 84-month loan would be ~$430 per month, ~$6,500 in total interest

The lower monthly payment may seem like a better deal, but the longer you keep the loan, the more expensive it will be.

Cars can also lose value very quickly. A car’s value typically drops by about 15% immediately after leaving a dealership.

If you make no down payment and take a long loan, you may owe more than the car is worth. For example: After two years, a car might be worth $20,000 while you still owe $24,000.

To be on the safe side, consider the “20/4/10 Rule” when buying a car:
  • 20% down payment
  • 4-year maximum loan term
  • Total car costs under 10% of your gross monthly income

I wanted a new truck. The dealer asked me what I could afford and I said, "$500 a month." He smiled and said he could make that happen. He stretched the loan to 84 months (seven years!). Three years later, I now want to sell the truck, but I still owe $28,000 on it and it's only worth $20,000. I am trapped in this vehicle because I bought the payment, not the car.
