Trade-In Tax Savings
In most states, trading in your old car reduces the sales tax on your new one. A $10k trade-in could save you $600-$900 in taxes.
APR Impact
Your credit score dictates your APR. A 1% difference in APR on a $30k loan can cost you over $800 in extra interest over 5 years.
Negative Equity
Owe more than your car is worth? This calculator automatically adds that 'negative equity' to your new loan balance.
Auto Finance FAQs
Does trading in a car reduce sales tax?
In most US states (like FL, TX, NY), YES. You only pay sales tax on the difference between the new car price and your trade-in value. This calculator automatically applies this credit.
What is a good APR for a car loan in 2025?
For new cars, a good APR is between 5-7% for excellent credit. For used cars, rates are typically higher (7-10%). Rates above 12% are considered high risk.
Should I take a 72 or 84 month loan?
While longer terms lower your monthly payment, they drastically increase the total interest paid. We recommend sticking to 60 months (5 years) or less to avoid being 'upside down' on your loan.
What does 'Upside Down' or Negative Equity mean?
It means you owe more on your trade-in than it is worth. This calculator handles that by adding the negative equity to your new loan balance (known as rolling it over).
