It really depends on how you look at "profit". For example, i have 2 food business at this time, 1 cafe/bakery and 1 lg kitchen where we do contract food for a private school and catering. I have a manageing partner at the cafe. Im there a couple times a week to consult and drink coffee and of course audit everything. After paying everyone there a above competive wage and myself a good salary from there plus an admin fee to my parent company, and my partner having a company car( nice one) our pelimary for year end there is 6.4% of witch my partner get a 35% cut and the asst get 7%. I get the other 58%. The taxman then swoops in and takes about 50%. Our sales are a bit over 5 million $ a year. This has been a good year for equipment and repair witch helps and sales were up 3 % since we had an excellent summer weather wise.
My large kitchen does more in sales per year but I pile on a lit of expenses onto it that take from the "profit". ie all travel, training, cars, trucks, insurances, marketing and such plus a salary for myself and my wife. This pelimary for the year end is 3.2%. Hence the tax man gets less.
Id love to get down to just breaking even.
