$1,000 a month for 30 years at 7% grows to about $1.22 million.
Hand an advisor 1% a year and your return drops to 6%, so you finish with roughly $1,004,500.
That's $215,000 gone.
A total market index fund charging 0.05% leaves you near $1.21 million, which is why I check the expense ratio before I look at returns.
