  3. Click Calculate to see the total price within reach.

The formula

It works backwards from the payment. The monthly budget tells you how big a loan you can support, and adding your down payment gives the price you can target.

r = annual rate / 12, n = term in months loan = payment x (1 - (1 + r)^-n) / r price = loan + down payment

A real example

With 450 dollars a month at 7.5 percent over 60 months and 3,000 down, you can target a specific sticker price. Increasing the down payment or stretching the term raises that number, but a longer term means more interest overall, so the cheaper-looking monthly payment can cost more in the end.

Common questions

Does this include tax, title, and fees?

No. Those add to the out-the-door cost. Leave some room in your budget for them and for insurance.

Is a longer term a good idea?

It lowers the monthly payment but increases total interest and the risk of owing more than the car is worth. Shorter terms cost less overall.
