How This Tool Works
This calculator uses the standard loan amortization formula to turn your vehicle price, down payment, trade-in, APR, and term into a monthly loan payment — after adding sales tax, registration, and dealer fees to get your true amount financed. It then adds your monthly ownership costs (insurance, fuel, maintenance, parking) on top, so you see the real all-in monthly and total cost of owning the car, not just the loan payment.
FAQ:
The calculator adds the vehicle price, sales tax, registration fee, and dealer/documentation fees, then subtracts your down payment and trade-in value (adding back any amount still owed on your trade-in). The result is financed using standard loan amortization based on your APR and term, and your monthly ownership costs are added on top to get the total.
Yes. Sales tax is calculated on the vehicle price minus your trade-in value (the method used in most US states), and the registration fee is applied as a percentage of the vehicle price. Both are added to your total purchase cost before financing.
Beyond your loan payment, factor in insurance, fuel or charging, routine maintenance, and parking or tolls. These recurring costs are often overlooked but make up a significant part of the true monthly cost of owning a car.
Yes. Your trade-in value is subtracted from the amount you need to finance, lowering your loan balance. If you still owe money on the trade-in, that remaining balance is added back in, since it becomes part of your new loan.
