Frequently Asked Questions
A money factor is the interest rate on a lease, expressed as a small decimal. Multiply by 2400 to get the equivalent APR.
Residual value is the estimated value of the car at the end of the lease, expressed as a percentage of MSRP.
Monthly payment = (Net Cap Cost - Residual) / Term + (Net Cap Cost + Residual) * Money Factor. Then tax is added.
