welcome CBW.
that would be depends on what kind of business you start. if you buy existing business (which you have to pay much more than starting from scratch) that shows profit, you should be able to take home your salary plus profit.
but if you start from the beginning (lease a place, re-built inside depends on what kind of business you want, start advertising, hire people...etc), it would be difficult to show profits for .... few month or even few year. that will be depends on your business plan, marketing, advertising and how well you run your business.
if you want, you can take some sort of salary from your own shop from the first month. (heck, you can take $100,000.00 per month salary, if you really want), but that would go out from your own bottom line. so that will be meaningless.
when i started my business (well.... in Guatemala, but it is same everywhere in the world), My partner (his is Guatemalan) and I had a business plan. we had about seven month of extra capital in the bank, which means we were expecting 7 month in Red. According to his plan for Guatemala domestic coffee sales (he already had a very small local coffee sales), it would take 7 month for our new company to break even with new and bigger operation with few other employees..etc, new building rent, construction fee...etc. During 7 month, we decided not to take out any salary.
But fortunately, I was able to sell green beans to overseas two month after we opened the company (i was kind of lucky). so, from third month, we were in Black. (when we planned our business model, intentionally, we did not count on my int'l sales because we thought it would take closed to one year or more to sell (according to other exporting company informational sales), that is why we were only rely on Guatemala domestic sales to break even point. Whatever we sold internationally, we put back the profit into company to grow faster.
hope that this reply had helped you. little bit of my experience.
if you have more questions, let me know.
