If you’ve got a book you’re itching to write, you can still go with the traditional publishing route. (We published our first book using a traditional publisher.) Whether your book is fiction or non-fiction, a publisher can help get your book into print and onto shelves in both online and traditional book stores.

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.
