First, Thanks! to all who helped. The biggest issues are NPV and IRR. NPV is a bit more complex than the PV. IRR is an iterative solution that uses NPV to get result.
I have the equations, I just did not want to reinvent the wheel if there was already a library out there. I have not found one yet, so I will be coding them myself. Just a minor pain when you are short on hours in the day.
