Truebill is an app that helps you save money by identifying recurring subscriptions and other bills and helping you cut costs by negotiating better rates and fees. One of their partnerships is with Acradia Power, which has the potential to save you up to 30% on your electric bill. It searches for better power rates in areas where competition is allowed, and it locks in the better prices for you.
I also noticed that in your passive income chart at the bottom that you don’t include your internet income other than sales from your book. Is there a reason for that? Do you not consider is passive because you are actively blogging all the time to create it? Or do you just not want readers to know how much money you generate from blogging activities?
First off, let’s address what is understood to be linear income. Employees, independent contractors, and self-employed business owners make up the linear income bracket. Linear income earners are only paid for the specific time expended, or paid directly proportional to the number of hours invested in their job. Linear income earners must be physically present or “clocked in” to get their paycheck.
You can’t start charging right off the bat without your audience knowing anything about the value you offer (though you could still indirectly earn money from them with the right ads). “The best way to go in terms of a long-term passive income business [is] delivering value and information for free, and therefore establishing expertise, knowledge and trust with your audience,” says Flynn.

Residual income can be calculated by taking the difference between the company's net income and its equity charge, where equity charge is the product of equity capital and the cost of capital. For example, a company has $5 million in net income with $20 million in equity capital and a cost of capital of 10 percent. The equity charge is 10 percent of $20 million, or $2 million. The residual income is $5 million minus $2 million, or $3 million.
What’s also really important to realize here is that when I took the exam I was teaching people to study for, I didn’t get a perfect score. In fact, I didn’t even get close to a perfect score. I passed. But I also knew a lot about this exam—way more than somebody who was just getting started diving into studying for it. And it was because of that, because I was just a few steps ahead of them, that they trusted me to help them with that information. To support this, I provided a lot of great free value to help them along the way. I engaged in conversations and interacted in comments sections and on forums. Most of all, I just really cared about those people, because I struggled big-time with that exam myself.

Investing in a business: Another good way to generate passive income is to invest in a business --even a small one -- in return for a percentage of the profits - just like Shark Tank, only smaller. Lending $10,000 to a local business that, for example, is working on a mobile app for Apple phones could lead to a passive income-generated share of the profits when that mobile app starts selling like hot cakes.
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.
