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
