The 20/4/10 rule: put 20% down, finance for no more than 4 years, and keep the payment at or below 10% of your gross income. For $72,000/year, that's $600/month max—which at 7% for 5 years supports about a $30,000 loan. Add your down payment for max car price.
20% down payment, 4-year loan max, payment ≤10% of gross monthly income. It prevents overspending on a car and keeps total transportation costs manageable. Adjust for your situation—some use 15% of income.
Financial experts recommend no more than 10–15% of gross monthly income. At $6,000/month gross, that's $600–900. Include insurance and maintenance in your total car budget—they can add 50–100% to the payment.
A larger down payment reduces the loan, monthly payment, and total interest. It also helps if the car depreciates faster than you pay it off (negative equity). Aim for at least 20% to align with the 20/4/10 rule.
