Crowdfunding can be a tool for investing and increasing income returns, but it is still horribly understood by most. Many of the best crowdfunding campaigns don’t offer returns at all. Promoting your own campaigns can help gain leverage, but success is often a lot more work and money than most realize. Most might be better sticking with direct private lending, or simply direct investment.
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.
