A system and related embodiments are presented that establishes a goal guarantee for a user that provides the user a guarantee of acquiring, at a future date, a life goal based on the user providing a predetermined funding amount over time to a life goal account. The life goal includes goods, real estate and/or services. The predetermined funding amount is determined based at least in part on a predicted future cost for the goal and an uncertainty calculation associated with the user. Once funds are accumulated in the life goal account, the invention provides for automatically reallocating funds in the life goal account from a higher uncertainty investment to a lower uncertainty investment in response to one or more predetermined triggering events, such as dates, amount thresholds, meeting predetermined price thresholds for the goal or components of the goal.
