Frequently Asked Questions
Q: How does a trade-in reduce my loan amount?
Your trade-in's value is subtracted from the vehicle's price before calculating your loan principal, lowering what you finance.
Q: Is sales tax charged on the full price or after trade-in?
This varies by state — many states tax only the price after trade-in credit, but not all.
Q: What's a typical auto loan term?
Common terms range from 36 to 72 months, though longer terms (up to 84 months) are increasingly available.
Q: Does a longer loan term save money?
No — while it lowers your monthly payment, you'll pay more total interest over a longer term.
Q: How much down payment should I put on a car?
A common guideline is at least 10-20% to avoid being "underwater" (owing more than the car's worth) early on.
Q: What's negative equity?
When your loan balance exceeds your car's current value, often from a small down payment or fast depreciation.
Q: Does my credit score affect my auto loan rate?
Significantly — higher credit scores typically qualify for meaningfully lower APRs.
Q: Should I get pre-approved before shopping?
Yes — pre-approval gives you a benchmark rate to compare against dealer financing offers.
Q: Are dealer incentives included in this calculator?
No — this estimates based on the numbers you enter; manufacturer rebates or incentives should be applied to the price first.
Q: Can I pay off my auto loan early without penalty?
Most auto loans allow this, but always confirm — some loans include prepayment penalties.
