The most expensive thing in most portfolios isn't a bad market year — it's the annual fee drag that compounds year after year. A single 1% annual fee can quietly consume 25-30% of your final portfolio value over 30 years. Most account holders never see it on a statement, but it's the biggest lever they have.

Illustrative only. All calculations assume a constant annual return and constant annual fee applied to the entire portfolio balance. Actual results vary based on market performance, individual fund expense ratios, advisor billing frequency, and other factors.
What "fees" include. A 1% advisor fee is typical for fee-only RIAs. Wirehouse and full-service brokerages can charge 1.25-2%. Add mutual fund expense ratios (0.5-1.5%), 12b-1 fees, wrap program fees, and hidden trading costs and the total "all-in" cost of a typical managed portfolio can exceed 2-3% annually.
