In fact, DIY Investor charges .40% management fees and invests primarily in low cost cost index funds (many of which now have zero commissions) which have an expense ratio of approximately .15%. In contrast, many advisors charge 1% management fees and use mutual funds that have expense ratios on the order of 1.3% and, to boot, are actively traded.
What is the impact on fees over the longer term? DIY Investor looked at this using actual market returns over the past 20 years as reported on the BlackRock table of investment performance. This analysis showed that, for a starting portfolio of $1.0 million, the end result was $857,585 less with a 1%/year management fee compared to a 0% (i.e. do-it-yourself investor) where both the manager and the do-it-yourselfer matched market returns. Of course, if you are convinced that your manager can "beat the market" by more than 1%/year then, by all means stay with the manager.

No matter how you look at it - portfolio management expenses are expensive over the long run!
