Instead of picking a car and hoping the payment fits, start from the payment you are comfortable with and see what car price it supports. Enter the monthly payment you can afford, the annual loan interest rate, the loan term in months and any cash down payment, and this calculator reverses the loan formula to find the largest amount you can finance, then adds your down payment to give a maximum sticker price. It also shows the total loan amount and the total you will pay over the term. This budget-first approach keeps you from being talked into a longer term or a bigger loan than you planned. Remember it covers the vehicle price only, not tax, registration or insurance, so leave a little room. All calculations run locally in your browser.
