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]
The above seems simple enough, but it’s pointless if it’s not put to work toward calculating the actual intrinsic value of the company. And since the residual income valuation formula is an absolute approach to company valuation, it discounts future earnings to get to the fair value of company stock. To calculate the value of the stock, one has to add the book value and the present value of expected future residual income, discounting the cost of equity (illustrated in the first formula below with the symbol . For the purposes of valuation calculation with formula 1, the company will presumably continue to evolve toward maturity, or constant growth. Formula 2 below is for calculating Terminal value. Constant growth () from year is presupposed, according to the PGM (Perpetuity Growth model).
Thanks for writing this Mr. Samurai. I just got over the student loan hump but I feel pretty good about it at 27 having a graduate degree and being 100% debt free. Now that I’m on the other side it is good for my brain to absorb some of your knowledge regarding passive income investments. I love gleaning wisdom from older folks who have been there and done that. Mentors rock!
1. The batting cage idea is very risky. I’ve seen many of them close over the years and it is not anything close to passive income if you want to keep the business going. You have to continually promote it and target youth leagues, coaches, schools etc to catch all of the new players who grow up and want to play. I’ve played at probably 8 batting cages over the years and 7 of them closed.

In 2012, even I wrote a 150-page eBook about severance package negotiations that still regularly sells about ~35 copies a month at $85 each (2nd edition for 2017) without any effort. In order to generate $2,975 a month or $35,700 a year in passive income as I do now, I would need to invest $892,500 in something that generates a 4% yield! To earn $10,000 a year in passive income would therefore need roughly $250,000 in capital.
My esteemed marketing colleagues initially balked at the idea of creating products that generate royalties, so I can understand how creating something from nothing might be daunting for those who aren’t even in creative roles. However, realize there is this enormous world out there of photographers, bloggers, artists, and podcasters who are making a passive income thanks to the Internet.

For example, you can design digital products, like animal clipart or a downloadable wedding poem that could be printed by the customer. Your design could be resold thousands of times without needing to create each item or ship it. Once you create your digital product and list it on a site like Etsy or Ebay, the revenue flows in with little oversight.
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.
