Authored by renowned estate planning experts, the Tool Box puts powerful estate planning strategies in an easy-to-use, yet robust format. It also includes the Estate Planner Function Library and the Tool Box Templates.


An add-in to Microsoft Excel® the Function Library enables you to perform estate, retirement, charitable, financial, and tax planning calculations right inside your own spreadsheet. It installs over 100 custom functions that work just like Excel’s built-in functions, such as PV, FV, and PMT.

These templates are unlocked and fully editable so that you can modify and customize them with the calculation power of the Estate Planner Function Library and the presentation power of Excel.
