The expense ratio is the annual fee charged by an ETF or mutual fund, expressed as a percentage of assets under management. It covers management, administrative, and operating costs.
Annual Cost = Portfolio Value × Expense Ratio
A $100,000 investment in a fund with 0.03% expense ratio costs $30/year. The same amount in a 1.0% fund costs $1,000/year — a $970 difference that compounds over decades.
