Online courses have exploded in the past five years. Experts and creators can now create video courses to teach others their craft. A course can be about anything that people want to learn. Friends of mine have created courses and say the amount of effort is similar to writing a book. But once its done and starts to sell, it’s a solid passive income stream.
The goal of EVA is to quantify the charge, or cost, of investing capital into a certain project or firm and to then assess whether it generates enough cash to be considered a good investment. The charge represents the minimum return that investors require to make their investment worthwhile. A positive EVA shows a project is generating returns in excess of the required minimum return.

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.
