Actively managed mutual funds charge higher management fees than passive funds. Assume that the net return to an active fund (after fees) is 9.5% (0.79% per month) and the net return to a passive fund is 10.5% (0.875% per month). Assume that an investor saves $600 per month (end-of-month) over thirty years. What is the difference in the future value of savings between investing in an active fund and a passive fund?
