When you create residual income, you are taking a step towards making extra money in a manner that does not require constant effort. The stream of income is actually generated from something specific; a specific effort that you put forth to create the stream of income opportunity in the first place. Residual income is not always a passive manner of making money.
Residual income valuation (RIV; also, residual income model and residual income method, RIM) is an approach to equity valuation that formally accounts for the cost of equity capital. Here, "residual" means in excess of any opportunity costs measured relative to the book value of shareholders' equity; residual income (RI) is then the income generated by a firm after accounting for the true cost of capital. The approach is largely analogous to the EVA/MVA based approach, with similar logic and advantages. Residual Income valuation has its origins in Edwards & Bell (1961), Peasnell (1982), and Ohlson (1995).[1]

1. The final and most powerful form of residual income, in my opinion, is investing and insurance. Most people have 401K’s and IRA’s, so I am going to leave that for the investment side. Within that, I think our Foundation Freedom Phases is by far the easiest, safest and most powerful tool for several reasons: a. It is contractually guaranteed, so the terms cannot be changed once it has begun. b. It is truly residual because the cash-value growth is guaranteed and you don’t have to create, leverage, train, hire, rent or do anything but flow your money through it to get it. It requires no specialization or mastery, it’s just banking.c. Everyone does it. To survive, life requires you to bank in some fashion, meaning you earn money in some way, hopefully residually and you spend it. That will happen until the day you die. d. Our strategy takes advantage of that cash-flow and allows you to earn residual, passive, tax-free income forever. I can’t stress this enough. This is the easiest, riskless way to earn truly passive, residual income. e. Investing can be residual, but it takes more effort, skill, and planning. Further, there is the element of taxation and losses that take away and limit the consistent potential of our strategy.
