Hello,

I am trying determine the mathematical formulas used in an online auto loan calculator.

The loan calculator is located here, and has 4 different tabs with different calculations:

http://www.cars.com/go/advice/financing ... anCalc.jsp

- "Auto Loan Calculator"

- "Affordability"

- "Cash Back vs. Low Interest"

- "Buy vs. Lease"

I need help figuring out each tabs' formula:

eg.

Monthly Payment = ((vehicle price - (down payment + trade in value)) * sales tax * interest rate) / term months

Any and all help is greatly appreciated.

Best,

Jason
