How It Works
Our Auto Loan Us works securely in your browser to instantly compute your estimated monthly vehicle payment. It calculates the total amount financed by taking the car's price, adding your state's sales tax and dealer fees, and subtracting your trade-in and down payment.
Formula Explanation
We use standard amortized loan formulas. The principal is calculated as: (Price - Trade-in - Down Payment) + Sales Tax + Fees. The monthly payment is calculated as: P * [r(1+r)^n] / [(1+r)^n - 1], where P is Principal, r is the monthly interest rate, and n is the loan term in months. If your interest rate is 0%, the payment is simply Principal divided by the number of months.
Example Calculation
For a $25,000 car with a $5,000 down payment, $0 trade-in, 7% sales tax, $500 in fees, and a 6% interest rate over 60 months: Your taxable amount is $25,000, tax is $1,750. Total loan amount is $22,250. The monthly payment will be exactly $430.15, totaling $3,558.82 in interest over 5 years.
Common Mistakes
A common mistake when using a auto loan us is forgetting to include dealer documentation fees or state registration fees, which can add $500 to $1,000 to your loan. Another mistake is focusing only on the monthly payment instead of the total interest paid���stretching a loan to 84 months lowers your payment, but significantly increases your overall cost.
Frequently Asked Questions
Does this calculator handle 0% APR auto loans?
Yes, if you enter 0% for the interest rate, the calculator will divide the total loan amount evenly across your chosen term without applying any interest.
How is sales tax calculated on a car with a trade-in?
In most states, sales tax is calculated on the difference between the new car's price and your trade-in's value. This calculator automatically deducts the trade-in value before calculating the tax amount.
Should I include dealer fees in my loan amount?
Yes. Unless you plan to pay dealer document, title, and registration fees upfront in cash, they will be rolled into your loan amount and you will pay interest on them. You can add them to the 'Dealer & Reg Fees' field.
