If someone invested $100,000 in a fund, and the fund earned 10% (few do), the total dollars paid by the investor would be $4,000 ($100k x 2% = $2,000 + $10,000 x 20% = $2,000). That means instead of making $10,000 on your $100,000 investment; you walked away with $6,000! Instead of a 10% return, you earned 6%! That’s a 40% drop in your profit!
