Abstract: The present invention relates to a method and system for measuring investment performance (e.g., total portfolio performance of individuals). In one example (which example is intended to be illustrative and not restrictive), the method and system may be used for measuring investment performance of personal pension portfolios. In another example (which example is intended to be illustrative and not restrictive), the method and system may provide for measuring performance of an investment portfolio held by an investor, comprising: providing first information indicating how the investment portfolio has performed over one or more predetermined periods of time; and providing second information indicating how investment portfolios of the investor's peer group have performed (e.g., on average) over the predetermined period(s) of time.
