It is helpful to use a car loan calculator to determine what the cost for a new or used car purchase will be monthly.

These can be found online with options for buying or leasing.  This is a helpful tool in determining what your budget actually is and how much car you can afford.  Just remember to factor in other car costs, such as maintenance and new car warranties.

Just remember that the numbers on a vehicle loan calculator are not actual quotes.  The calculator allows you to compare the costs of different cars and see what your payments per month will be.

On the calculator there is a line to enter the dollar amount you would like to finance. Then, by clicking your mouse you can compare what payments will be, with different arrangements for paying.  You can also find out what interest payments will be for the life of the vehicle loan. 

It is a bonus to use a car loan calculator before going to a dealership to buy a vehicle.  You will already know what your budget is, which will allow you to make a smart purchase.  You will also know how much money you have left over to spend on maintenance costs and an auto warranty.
