Successful YouTubers choose a theme for their channel—ranging from humorous commentary to gardening. As you acquire subscribers to your channel, your number of views becomes more consistent, which in turn grows your residual income. While you’ll need to produce regular videos to maintain your following, a couple hours of filming and editing pales in comparison to the revenue you can generate with minimum effort.
This can be a little easier said than done, but if you have a large social media following, you can definitely earn money promoting a product or advertising for a company. You can even combine this with different marketing campaigns if you are an influencer and have your own blog (advertisement + affiliate income). This is how many bloggers make money! Again, it is not 100% passive but once set up correctly and then scaled, can be surprisingly lucrative.
In equity valuation, residual income represents an economic earnings stream and valuation method for estimating the intrinsic value of a company's common stock. The residual income valuation model values a company as the sum of book value and the present value of expected future residual income. Residual income attempts to measure economic profit, which is the profit remaining after the deduction of opportunity costs for all sources of capital.
