While residual income can be used to describe the amount of net income after all costs are paid down, it also refers to the amount of money you continue to generate after your initial work is done. There are countless ways to make money, but some are much more time-intensive than others. Active income, for example, refers to when you directly act or perform a service for money, including salaries, wages, tips, commissions, and income from a business you’re actively involved with.
Typically, the above formula will be applied such that the company is assumed to achieve maturity, or "constant growth". (Note that the value will remain identical: the adjustment is a "telescoping" device). Here, analysts commonly employ the Perpetuity Growth Model to calculate the corresponding terminal value[3] (although various, more formal approaches are also applied[4]). Then, assuming long-run, "constant", growth {\displaystyle g} from year {\displaystyle m} , the terminal value is

I am 30 years old and am retired. Previously, I made a modest salary as an Army officer. I own three duplexes and a quadplex in central Texas (10 rental units in all), and each of the properties provide me with net rental yields in excess of 15%. The last deal is actually an infinite return as my partner paid the down payment in return for a 50/50 split on a property that would otherwise provide a net rental yield of 18%. The above net rental yields also factor in an excellent property management team who manages my properties while I pursue other investment opportunities. To date, I have never interacted with any of my tenants nor have I ever had to personally deal with any maintenance issues.

Vanguard: Vanguard has a minimum of $50,000 and a fee of 0.3%. Rebalancing is done automatically once every quarter and tax loss harvesting is done on a client-by-client basis. We included Vanguard because clients who invest between $50,000-$500,000 have access to a team of financial advisors. Those with accounts over $500,000 will have a dedicated advisor.
You don't have to be Paul McCartney to rack up residuals. You might own properties that you rent out even though you're not a Realtor. Maybe a blog you started took off, and while you no longer work there, you still collect part of the profits. Or perhaps you're a serial entrepreneur who creates companies and moves on. You, too, are earning residual income.
Another benefit of residual income is that, if the income stream is large enough, one does not need the main focus of his life to be on making enough money to survive. Having a comfortable and continuous level of residual income opens up more opportunities to travel, look into other business opportunities, and even take the time to indulge in his hobbies.
The vast majority of my investing is in retirement accounts and won't be tapped for income until I reach at least 59.5 years old. However, I have a very small taxable investing portfolio (less than $5k) with Ally Invest where I invest in a handful of stocks that I value. I do not use the earnings as income – I simply hold these stocks. But I have an unrealized gain of $340 from this year so far.
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.
