Two SKUs
The purchase page distinguishes Excel Gold (indefinite use of a version, paid again for a new version) from Pralana Online (annual subscription, three scenarios on the individual plan). This comparison uses those published figures. It does not score the Excel model’s accuracy.
Which one to choose
Choose Killion if
- You want a browser demo, named withdrawal rules and a methodology page you can cite.
- You are not trying to sequence Roth conversions this year.
Choose Pralana if
- You want a tax-lot-aware, conversion-aware projection and you are willing to live in Excel or Pralana Online.
