My dividend portfolio on Motif Investing holds three exchange-traded funds and 10 individual stocks. Just one of the stocks (Ford Motor) has a negative return and the entire fund is up 34% over the past year.

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.
I’m a 45 year old business owner who also has focussed on diversifying my income streams. I have a short term vacation rental in Florida that I bought for $390k in 2012 and net rental income for the last three years has been growing steadily. 2015 I am at $70k gross right now but should end up at $80-85k with net around $45k plus we use the place about 35 nights a year.

Managerial accounting defines residual income in a corporate setting as the amount of leftover operating profit after all costs of capital used to generate the revenues have been paid. It is also considered the company's net operating income or the amount of profit that exceed its required rate of return. Residual income is normally used to assess the performance of a capital investment, team, department or business unit.
