The invention is directed to a method and system for providing an interface including modular customizable elements for implementation by a system user. The method and system have particular application for financial accounts, such as credit card accounts. The interface may adapt in response to user behaviors. However, the user may also customize features of the interface. Thus, a behavioral monitoring and analysis system is provided for monitoring account holder spending behaviors and analyzing the spending behaviors. Account holder customization tools may be presented to the account holders through a user interface, the account holder customization tools allowing account holders to modify a user interface display of account related parameters by inputting parameters into a computing system. An experience customization engine may be implemented by a processor for receiving input from both the behavioral monitoring and analysis system and the account holder customization tools.
