A. It depends on the return the financial advisor generates for you and the fees you pay for it. Based on average numbers shown below, you probably can come to your own conclusion:
Financial advisor's annual fee: 1% of assets under management is typical.
Annual return of your portfolio: average 7% is probably reasonable. Of which, 2% is about dividend yield, leaving 5% to earnings growth.
Annual inflation: about 2-3%. So your after-inflation annual return is about 4%.
Actively managed funds' annual fees is about 2% per year. So your net return is about 2%.
Tax impact: mutual funds are tax inefficient, let's assume it takes away another 1%.
It leaves you 1% - just enough pay for your financial advisor!
