Vehicle Affordability Guide: How Loan Terms Affect Buying Power
Stretching your loan term is the easiest way to lower your monthly payment—or buy a more expensive car for the same payment. But is it a smart financial move? This guide explains the trade-offs between purchasing power and total interest costs.

Impact of Loan Term on Price
If you can afford $400/month, how much car can you buy?
- 36 Months: You can buy a cheaper car (e.g., ~$13,000) but pay very little interest.
- 72 Months: You can buy a more expensive car (e.g., ~$25,000) because you have twice as long to pay it back.
This is why dealerships love to focus on payments rather than price. They can sell you a more expensive car by simply extending the loan.
Depreciation & Being "Underwater"
Cars lose value quickly. If you have a long loan term (6+ years), your car's value might drop faster than your loan balance. This is called being "underwater" or having negative equity.
Risk: If you want to trade in the car after 3 years, you might owe more than it's worth, forcing you to roll the negative equity into your next loan.
