What I did:The first two years of work in NYC was brutal. I told myself there was no way I could work on Wall St for my entire career because I’d probably die from heart failure by age 40. Having an early death in my mind willed me to save 50%+ from the first year onward and devise a CD, real estate, and stock investment distribution system for my savings every year. I thought about starting this site for at least a year before I hired someone from Craigslist to give set me up and push me forward. Hiring someone to get started is totally worth it if you are a master procrastinator. You can now learn how to start your own site with my step-by-step guide to save yourself time and money. 
I have had a LC account for almost 2 years. Invested 5k. A lot of very small loans. Unfortunately I had to invest though Folio FN. The fees reduce your return. Now, they are not even allowing that. My interest and return of principal are not being reinvested. I talked with LC and they are working on it for my state. Even if I can obtain access to the prime portfolio, I would only place 10 percent of my cash here and would reinvest for at least 3 years. I am still concerned about what would happen when a recession hits.
Residual income is calculated as net income less a charge for the cost of capital. The charge is known as the equity charge and is calculated as the value of equity capital multiplied by the cost of equity or the required rate of return on equity. Given the opportunity cost of equity, a company can have positive net income but negative residual income.
