The Real Cost of Car Ownership
Cars are depreciating assets. Buying more car than you can afford is one of the fastest ways to destroy your wealth-building potential. The sticker price is just the beginning; you must factor in insurance, gas, maintenance, and interest.
The 20/4/10 Rule
Financial experts highly recommend the 20/4/10 rule for car buying:
- 20% Down: You should put down at least 20% to avoid being instantly underwater on the loan as the car depreciates leaving the lot.
- 4-Year Loan Term: Do not finance a car for more than 48 months. While 72 and 84-month loans lower your monthly payment, they trap you in negative equity and cost thousands in extra interest.
- 10% of Income: Your total transportation costs (loan payment, insurance, gas) should not exceed 10% of your gross monthly income.
Calculate Before You Shop
Dealerships excel at focusing negotiations entirely on the "monthly payment" rather than the total cost of the car. Use an independent auto loan calculator to figure out your maximum purchase price before you even set foot on a lot.
