October 6, 201114 yr We have had headaches, for years, dealing with APR Calculations involving Loan Processing Fees. It is related to Fed. Regulations. Accountants use a standard IRR Calculation for this, but FileMaker is a bit limited on that front. I've written one, back in FM 6, but we prefer to go with something more standard. We currently use Excel when needed. Last night, I was Googling, out of curiosity. I saw references to a Groovy based Financial package, with an IRR Calc: FinancialService.IRR. I haven't found any reference as to where it comes from & I haven't written any plugins myself yet. Anybody know where this package comes from (part of Groovy, 360Works, another company)?
