US Auto Loan Calculator
Stop negotiating monthly payments at the dealership. Use this precise engine to calculate your absolute Out-the-Door Price, understand the physical impact of Dealer Fees, and measure true Interest cost over the term of your loan.
The Math Behind It
PMT = P × [r(1+r)^n] / [(1+r)^n - 1]Auto loans in the United States operate under aggressive Simple Interest mechanics. Dealerships usually calculate the State Sales Tax on the margin between the New Vehicle Price and your Trade-in value (saving you money on taxes). However, they offset this by injecting non-negotiable 'Dealer Fees' and 'Doc Fees' directly into the cash footprint before compounding strictly across the Loan Term.
Example
If you buy a $32,000 truck with a $5,000 Trade-In and $899 in Dealer Fees at 6.5% Sales tax, your Tax burden is just $1,755 (because the trade-in shielded $5k from taxation). Your Out-the-door price spikes to $34,654. After your $3,000 baseline cash down payment, the bank essentially loans you $26,654 over 60 months.
