The expense ratios on bond mutual funds can vary dramatically. The average expense ratio in $2020$ for all bond funds, both index funds and actively managed funds, was $0\mathrm{.}48$ percent, and this ratio ranged from approximately $0\mathrm{.}08$ to over $2$ percent. Given the fact that the interest rate on $10-$year government bonds was less than $1$ percent at the end of $2020,$ it$$s extremely important to keep expenses low if you$$re investing in bond funds. If your expenses are $2$ percent and your return is only $1\mathrm{.}00$ percent, you$$re not doing well at all. What does this tell you about what to look for when choosing a bond mutual fund?
