The Vehicle Loan Calculator is the most convenient way to calculate your monthly car loan payment, as it shows the amount you will have to pay, the interest rate, and the amount of money you will receive, depending on the loan amount and the price of the car you are purchasing. 

The calculation can be performed on one of the following three methods:

If you are purchasing a car from a dealer, you can enter the information required for the calculation, plus any optional information you want to add, and then press the calculate button. 

If you are not interested in purchasing a car, you can simply leave the information you need for the calculation as 0, and the app will show you how much money you will receive.
