About

About the Automobile Finance Calculator

This calculator will calculate the monthly car payment and total purchase costs you will end up paying between when you buy the vehicle and when you make the final payment.

Plus, unlike other auto finance calculators, the calculator in this web-app will also calculate if and for how long you might be upside down in the car loan.

Finally, the calculated results also include a "Printer Friendly Schedule" button so you can print out the schedule for later reference.
