Then the store usually has 6-10 employees, and a back-up manager. This will run the store about $6,000 to finance 6 employees at $250 a month per person. Then you also want to make money for yourself, and most owners of a convenience store(one that is not a chain) can generate about $2500 to keep for themselves.
Answer Wiki. That would very much depend on the location, if you are independent, if you are buying in an existing business or if you are taking over some kind of franchise (7/11) or co-op and how local competition looks like. However, location is everything. Convenience shop owners don't take home 75k-100k per year right away. You need to fork up the cash to properly invest in a business first, where you will funnel in your life savings or go to a bank and take a loan. So either the bank owns 90% of your store or you yourself have everything tied up in your store.
