Frequently Asked Questions
On a $30,000 loan at 6.5%:
- 48 months: $711/mo — total interest $4,150
- 72 months: $504/mo — total interest $6,309
Difference: $207/mo more for 48 months, but you save $2,160 in total interest.
Financial advisors generally recommend a maximum of 60 months (5 years) for new cars and 48 months for used cars. The '20/4/10 rule' is a useful guideline: 20% down payment, maximum 4-year loan term, total transportation costs under 10% of gross income. Longer terms (72–84 months) cost significantly more in interest and leave you 'underwater' — owing more than the car is worth — for an extended period.
Choose shorter (36–48 months) if: You can comfortably afford the higher payment, you plan to keep the car long-term, or you want to minimize total cost.
Choose longer (60–72 months) if: You need lower payments to stay within budget, you have stable income but limited current cash flow, or you're buying a reliable vehicle you'll keep for 6+ years. Avoid 84 months — the interest premium and equity risk rarely make sense.
On a $30,000 car loan at 6.5%: 36 months = $3,101 interest, 60 months = $5,219 interest, 84 months = $7,421 interest. Each additional year adds roughly $500–$800 in total interest for every $10,000 borrowed at 6.5%.
Not necessarily, but it comes with real risks. You'll pay more in interest and be 'upside-down' (owing more than the car's value) for roughly the first 24–30 months. If the car is totaled or you need to sell early, you'd owe more than insurance pays. If you're considering 72 months because 60 months is unaffordable, that's often a sign the car is priced above your budget — consider a less expensive vehicle on a 48–60 month term instead.
