Minimum initial investment
The minimum amount of money you need to begin investing in a specific mutual fund.
Exchange-traded funds (ETFs) have no minimum initial investment requirement beyond the price of 1 share.
Expense ratio
A mutual fund's or exchange-traded fund's (ETF's) annual operating expenses, expressed as a percentage of the fund's average net assets. It's calculated annually and removed from the fund's earnings before they're distributed to investors, directly reducing investors' returns.
An expense ratio includes management, administrative, marketing, and distribution fees. It doesn't include loads or purchase or redemption fees.
