But over what term? As a true guide to how you are performing vs a standard index such as S&P500 or MSCI World Index, you need to calculate your money-weighted rate of return (quite easily done in an Excel spreadsheet), which caters for the timing and amounts of any ongoing deposits and (if any) withdrawals. If you aren't beating those indices, you will be better off just investing in them. An index averaging 10% per year, with no additional contributions may well show a 50%+ profit in 4 years or so.
