Thus, the residual income approach is better than the return on investment approach, since it accepts any investment proposal that exceeds the minimum required return on investment. Conversely, the return on investment approach tends to result in the rejection of any project whose projected return is less than the average rate of return of the profit center, even if the projected return is greater than the minimum required rate of return.

Real estate is the obvious choice if you are going to make money on your money. I personally am not at the point where I can do any of this in a meaningful way BUT my parents are and they now own a couple homes outright and are collecting income from them to power their retirement income. It makes a lot more sense for anyone that has a chunk of cash sitting in the bank and are planning on slowly drawing from it because you technically still have all that money in a property (or multiple properties) and can sell them if you really need the lump sum of cash but you’ll earn great interest payments until you do that.
What are your thoughts on an Immediate Annuity as a passive income vehicle? I suppose it’s not a great investment since you never get your principal back, but the risk is zero and the cash flow is fairly good, approaching 6% currently. And, since you are guaranteed payments for life, you may not care that you never see your principal again anyway since you’ll be dead!
Companies use the return on investment, or ROI, ratio as a method to measure the rate of return of a company's capital investments. ROI gives companies a means to compare the effectiveness and profitability of any number of investments. Residual income measures the net income an investment earns beyond the lowest return on its operational assets. Each of these measurements enables company management to determine the profit potential of investments in capital improvement, proposed projects or potential acquisitions.
Even if each patron only contributes a very small amount each month, it can still be a huge source of income. Take a look at the Patreon page for Kinda Funny, an internet video company. They have over 6,209 patrons which means an average of just $3 a month would be a monthly income of almost $19,000 – plus they get cheerleaders that are always happy to spread the word on their brand.

During the trial, Karen offered proof that she and Brad had built the business together, and that the downline was the result of their joint efforts – not just Brad’s. Karen argued that the residual income from the downline should therefore be split at a 60/40 rate on a monthly basis. Brad, on the other hand, asked the trial court to value the business. Upon valuation, the court could either allow him to buy out Karen’s share or direct that the business be sold, with the proceeds being split 60/40 between the two parties.
Passive income, after everything is set needs no associated cost. Sure, it’s going to take considerable time upfront, but you don’t even have to work it every day. You can begin part-time and as your revenues build and take over your current main income, begin the transition to working as an entrepreneur full-time. And, typically, this type of recurring monthly income won’t lock you down to a specific location and you can work from anywhere you have a laptop and Internet connection.
You are also free to choose a fund that is based on any index that you want. For example, there are index funds set up for just about every market sector there is — energy, precious metals, banking, emerging markets — you name it. All you have to do is decide that you want to participate, then contribute money and sit back and relax. Your stock portfolio will then be on automatic pilot.
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.
