Frequently Asked Questions

How much should I spend on a car based on my income?

A general rule is to spend no more than 10-15% of your gross monthly income on car payments. For a $50,000 annual income ($4,167/month), you should aim for payments under $400-625/month. Remember to factor in insurance, gas, and maintenance costs.

What is the 20/4/10 rule for car buying?

The 20/4/10 rule suggests: 20% down payment, finance for no more than 4 years, and keep total monthly vehicle expenses (payment + insurance + gas) under 10% of gross monthly income. This helps ensure affordable car ownership.

Should I buy new or used to maximize affordability?

Used cars typically offer better affordability since they have lower purchase prices, insurance costs, and depreciation. A 2-3 year old car often provides the best balance of reliability, features, and affordability compared to new vehicles.

What costs should I include when calculating car affordability?

Total car ownership costs include: monthly payment, insurance, gas, maintenance, repairs, registration, and depreciation. Many buyers only consider the payment but these additional costs can add $300-500+ monthly to your budget.

How does my credit score affect car affordability?

Credit scores significantly impact interest rates. Excellent credit (750+) might get 3-5% rates, while poor credit (600-) could see 10-15%+ rates. A higher rate means higher payments, reducing how much car you can afford for the same budget.

Is it better to finance or lease a car for affordability?

Leasing typically has lower monthly payments but no ownership equity. Financing costs more monthly but builds equity. For maximum affordability, consider financing a reliable used car and keeping it long-term to minimize per-year costs.
