📐 The 20/4/10 Rule

Financial experts recommend the 20/4/10 rule for car buying:

  • 20% Down: Put at least 20% down to avoid negative equity.
  • 4 Years: Limit the loan term to no more than 4 years (48 months).
  • 10% Income: Keep total car costs (payment + insurance) under 10% of your gross income.

How Much Car Can You Really Afford?

Buying a car is one of the largest financial decisions you'll make. It's easy to get caught up in the excitement of a new vehicle and overlook the long-term impact on your monthly budget. Our calculator helps you find a "safe" price point based on your actual income.

The Danger of Long Loans

While 72-month or 84-month loans make monthly payments look attractive, they often lead to "negative equity"—where you owe more on the car than it's worth. This is especially dangerous given how quickly new cars depreciate.

🏦

Debt-to-Income

Lenders look at your Debt-to-Income (DTI) ratio. Even if you can "afford" the payment, a high DTI might prevent you from getting a mortgage or other important loans later.

🛡️

Hidden Costs

Don't forget registration, taxes, and insurance. A $500 monthly payment often turns into $700+ in total monthly ownership costs.

📈

Interest Impact

A 1% difference in interest rate can save you thousands over the life of the loan. Always shop around for the best rate before visiting the dealer.
