It varies to much to just give you a generic answer. one of your company's costs may be the owners salary... in which case he is getting paid even if the company isn't making a profit, it's coming from capital. Either in the form of owner investment or debt.

In a perfect world scenario, it would be great to be able to start a company without needing to draw an income from it for a year or longer. But most small business are started with an immediate need for income, so you hope you capital will last until your income exceeds costs/salaries...
