I have two major dilemmas: (1) Should I wait to start investing (at least until the end of the year where I’ll hopefully have $5k+ in savings) in things like CDs? I ask because a little over $2k doesn’t seem significant enough yet to start putting my money to work (or maybe it is? that’s why I’m coming to you for your advice haha) and (2) I want to invest in things like P2P and stocks but I’m honestly a bit ignorant of how it trully works. I know the basics (high risk, returns can be volatile, returns are taxable). Do you have any advice on how I can best educate myself to start putting my savings to work?

Residual income is calculated as net income less a charge for the cost of capital. The charge is known as the equity charge and is calculated as the value of equity capital multiplied by the cost of equity or the required rate of return on equity. Given the opportunity cost of equity, a company can have positive net income but negative residual income.
