Teachable and Udemy are two of many, but these are the most prevalent, and they’re both intuitive and user-friendly. With Teachable, you have more control over your pricing and the look and feel of your course, but you don’t get a built-in audience. Instead you have to do all the marketing yourself.

Residual income is the amount of net income generated in excess of the minimum rate of return. Residual income concepts have been used in a number of contexts, including as a measurement of internal corporate performance whereby a company's management team evaluates the return generated relative to the company's minimum required return. Alternatively, in personal finance, residual income is the level of income that an individual has after the deduction of all personal debts and expenses have been paid.
