Is anyone aware of a comprehensive tool that can model different retirement scenarios taking into account a variety of factors:

- date of retirement (me, wife or both)
- ss (early for one regular or later for another) and pension income
- current asset portfolio and ability to generate revenue from assets
- etc.

The model needs to be able to take all current information along with any income in future (depending if one or both of us works) and create a multitude of different financial scenarios. Most models simply tell you if you are meeting a set goal. I want to see actual cash flows in different settings.
