Residual Income equals net income minus opportunity cost. So in the stock trading example, your residual income is $4,000 minus $6,000 or negative $2,000. As you can see, an investment can produce negative residual income even if it helps your money grow . A negative residual income means that you could have done better by another, risk-free approach. Some analysts refer to residual value as Economic Value Added. If your residual value is negative, you are not truly adding value with what you are doing.
Quick story: Remember that $1.18 I found in the couch? Even when that increased to $30 to $50 a day, it still wasn’t enough to live on. So I looked for other options.

It included all the information I knew about passing this exam, and I sold it on my blog for $19.95.
