Individual customers and businesses can purchase your stock images for their websites and marketing materials. Simple stock photos, like businessmen shaking hands or a woman riding in a car, are sought after by many companies. To be most successful, you’ll want to upload photos monthly to consistently grow your portfolio. You’ll generate a commission each time one of your photos is downloaded.
A different definition of residual income is that this is income derived from passive investments, rather than from a person's active income-generating activities. Examples are interest income, royalty income, rent, and increases in the value of investments held. Individuals typically work throughout their careers in order to build up a sufficient amount of this income to support them during their retirement.
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.
