Abstract: Embodiments of the inventive subject matter are directed to retirement plan optimization. By collecting client information, systems and methods of the inventive subject matter are configured to develop scenarios for a user. From those scenarios, multiple simulations can be run. Each scenario features scenario parameters, and each simulation features simulation parameters. Scenario parameters can include ranges of values or a set of different possible values. For a given scenario, many simulations can be run, where each simulation has a corresponding set of simulation parameters, and where each set of simulation parameters features set values for each of the scenario parameters for that scenario. After running multiple simulations for each scenario, high performing simulations can be identified based on a base case performance and based on one or more optimization goals. Once high performing simulations are identified, actionable retirement plans can be developed therefrom.
