how do you figure lease payments?

Answer 1

Lease payment calculations are extremely complex and involve terminology that is very different from loan contracts. Unlike loans, there is little regulation of leases at the federal level. Some states do regulate leases and others do not. Some states don't even require leases to clearly state that it is a lease contract as opposed to a finance contract.

Have a look here for an on-line lease calculator and an explanation of the terms commonly used in lease contracts:
