How much car can I afford?

Follow the 20/4/10 rule: 20% down payment, 4-year (48-month) loan max, and total car costs under 10% of gross income. Total car costs = payment + insurance + gas + maintenance. Example: $60,000 income = $500/month total for car. If insurance is $150/month, your payment should be under $350. Many people overspend on cars - don't be car poor.

Should I get a 72 or 84-month loan?

Generally no. Long loans mean: 1) More interest paid, 2) Being underwater (owing more than car's worth), 3) Still paying when car needs major repairs. A 72-month loan on a new car = you'll owe more than it's worth for 3+ years. If you need 72+ months to afford the payment, the car is too expensive. Exception: 0% financing from manufacturer.

What credit score do I need for a car loan?

You can get a loan with most credit scores, but rates vary dramatically. 750+: 5-6% (excellent). 700-749: 6-8% (good). 650-699: 9-12% (fair). 600-649: 12-18% (subprime). Below 600: 18-25% (deep subprime). That difference is huge: $25,000 at 6% vs 15% costs $4,000 vs $10,000 in interest over 60 months.

Dealer financing vs bank - which is better?

Get pre-approved from your bank/credit union BEFORE visiting the dealer. Then let the dealer try to beat it. Dealer perks: convenience, manufacturer incentives (0% deals). Dealer risks: rate markup (they can add 1-2% to the rate for profit), focus on monthly payment instead of total cost. Having pre-approval gives you negotiating power.

New car or used car - which is the better financial choice?

Used cars are almost always better financially. New cars lose 20% value in year 1, 50% by year 5. A 2-3 year old certified pre-owned car saves you the biggest depreciation hit while still having warranty. Sweet spot: 3-year-old car with 30k-40k miles. You save thousands while getting a reliable vehicle. New makes sense only if: 0% financing, keeping 10+ years, or specific safety features needed.

How much down payment should I put on a car?

Aim for 20% down. This avoids being underwater (owing more than car's worth), reduces interest paid, and proves financial responsibility. At minimum, cover taxes, title, and fees (~10% of price) to avoid rolling them into the loan. More down = better: lower payment, less interest, more equity from day one.

Can I refinance my car loan?

Yes, refinancing can save money if: your credit improved since original loan, rates dropped, or you got a bad dealer rate. Process: Apply with banks/credit unions, they pay off your old loan, you make payments to them. Costs: Usually free or minimal fees. When it makes sense: Rate drops 1%+, at least 12 months remaining, not underwater on loan.

Should I pay off my car loan early?

Usually yes, if: 1) No prepayment penalty (most auto loans don't have them), 2) You have emergency fund, 3) No higher-interest debt. Benefits: Save interest, own car outright, free up cash flow, peace of mind. One exception: If your rate is very low (under 4%) and you'd invest the money instead, investing might earn more. But for simplicity, paying off debt is always a safe choice.

Understanding Your Results

Your auto loan results reveal both your monthly budget impact and the true cost of financing a vehicle over time.

What Each Result Means

Monthly Payment

Your fixed monthly car payment.

Interpretation: This should be under 10% of take-home pay. Remember to budget separately for insurance, gas, and maintenance.

Good: Under 10% of monthly take-home pay

Total Interest

The total interest you'll pay over the life of the loan.

Interpretation: This is the cost of borrowing. On a $30,000 car at 7% for 60 months, you'll pay about $5,500 in interest.

Good: Under 20% of vehicle price ideally

Total Amount Paid

Vehicle price plus all interest charges.

Interpretation: A $30,000 car often costs $33,000-$37,000 by the time you finish paying. Factor this into your decision.

What to Do With Your Results

If Payment over 10% of income:

Consider a less expensive vehicle, larger down payment, or longer term (with caution). Being car-poor limits your financial flexibility.

If Loan term over 60 months:

Beware of being underwater (owing more than car is worth). Cars depreciate fast - you could owe $20k on a car worth $15k.

If High interest rate:

Improve your credit before buying, get pre-approved from your bank/credit union, or consider a larger down payment.
