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.
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.
