This show the Formula and Initial guess used as well.

Here the estimate is PMT/PV – PV/PMT/n² (where PV and PMT follow the sign convention). This seems to work well, but it implies that FV is zero so that only PMT and PV are considered. The mentioned program was written for mortgage loans as a special case of the TVM equation.
