Mutual Funds and ETF's come with embedded fees, known as Expense Ratios. The general range is from a low 0.02% to a high of 2.50%, which is then multipled by the total value of your account. They are sneaky fees - no bills are sent - the cost is automatically siphoned from your portfolio. All Funds and ETF's are required by law to disclose and publish Expense Ratios.
