Many people associate work with punching the clock, the 9-to-5 slog and saving for retirement. The trouble is, an hourly rate alone will never make you wealthy and drains your most precious resource: time. Fortunately, you have alternative strategies. Unfortunately, you’ve probably never heard about them, as they’re usually reserved for the super-rich.

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.
