💡 Understanding Auto Loans
Your monthly car payment depends on the amount financed (vehicle price - down payment - trade equity + taxes/fees), the interest rate, and the loan term. Longer terms mean lower monthly payments but more total interest paid.
🚗 Smart Car Buying Tips
20/4/10 Rule: Put down at least 20%, finance for no more than 4 years, and keep total monthly vehicle expenses under 10% of gross income. This helps avoid being "upside down" on your loan.
⚠️ Watch Out For
Negative Equity: If you owe more on your trade-in than it's worth, that amount gets added to your new loan. Long Terms: 72+ month loans may seem affordable but cost thousands more in interest.
