Auto Loan Education

Understanding Auto Loans

Auto loans are installment loans with fixed monthly payments. Key components include:

  • Principal: Amount borrowed to purchase the vehicle
  • Interest: Cost of borrowing (APR)
  • Term: Length of loan (typically 3-7 years)
  • Down Payment: Initial cash payment
PMT = P × (r(1+r)^n) / ((1+r)^n - 1)
PMT = Monthly payment P = Principal loan amount r = Monthly interest rate (APR/12) n = Number of payments

  • New cars lose ~20% value in first year
  • ~40% depreciation after 3 years
  • ~60% depreciation after 5 years
Year 1 ~80% Value
Year 3 ~60% Value
Year 5 ~40% Value

Auto Loan FAQ

What is a good interest rate for a car loan?

As of 2024, excellent credit (720+) typically gets 3-5%, good credit (660-719) gets 5-7%, average credit (620-659) gets 7-10%, and below 620 may see 10%+. Rates vary by lender, loan term, and economic conditions.

Should I get a 3-year or 6-year car loan?

3-year loans have higher payments but lower total interest and help avoid negative equity. 6-year loans have lower payments but cost more in interest and may result in owing more than the car's value (negative equity). Consider your budget and how long you plan to keep the vehicle.

How much car can I afford?

The 20/4/10 rule is a good guideline: 20% down payment, 4-year maximum term, and monthly payment ≤10% of gross income. Also consider total transportation costs (insurance, fuel, maintenance) which should be ≤15-20% of monthly income.

What's the difference between APR and interest rate?

Interest rate is the cost of borrowing principal. APR (Annual Percentage Rate) includes interest plus fees, giving you the true cost of the loan. Always compare APRs when shopping for loans.
