About this tool

Auto Loan Calculator models a real car, truck, or SUV loan the way a dealership or refinance worksheet does. The Monthly payment mode takes your vehicle price, down payment (as an amount or a percent), trade-in value, trade-in payoff balance, sales tax rate, title and registration and documentation fees, APR, and term in months and returns the monthly payment, the total interest paid over the life of the loan, the total of payments, the total drive-away cost (down payment plus all payments), the payoff date, and a complete amortization schedule with both yearly rollups and a month-by-month breakdown of principal, interest, and remaining balance. Trade-in handling is realistic: negative equity (you owe more on the trade than it is worth) automatically rolls into the new loan and is highlighted as a warning so the buyer can see exactly how much extra principal is being financed. Sales tax can be applied either to the full vehicle price (a small number of US states do this) or to the price after subtracting the trade-in value (the default in most US states and most Canadian provinces with HST). The How much car mode reverses the question: enter the monthly payment your budget can carry, an APR, a term, sales tax, down payment, and fees, and the tool solves for the maximum vehicle price the budget covers. The Compare terms mode holds price, down payment, trade-in, tax, fees, and APR constant and fans out 36, 48, 60, 72, and 84 month terms side by side so the trade-off between a smaller monthly payment and a larger lifetime interest bill is impossible to miss. Six preset scenarios cover a new mid-size sedan, a used SUV with a small trade-in, a luxury vehicle at 84 months, a cash-heavy short term, an upside-down trade-in, and a 0% APR EV special. A currency picker switches between US Dollar, Canadian Dollar, Euro, British Pound, Australian Dollar, Indian Rupee, Japanese Yen, and Turkish Lira. All math runs in your browser using the standard fixed-rate amortization formula, so the prices, balances, and rates you enter never leave your device. The figures here are estimates; your dealer or lender has the final word on the actual rate, residual fees, and any applicable manufacturer rebates or incentives.
