Recent figures show that most caterers have a profit margin of?

I'm not an expert but I have a cafe and when I started my business advisor told me the average was about 65% - if you can get above that you are doing well.

Just to clarify, to get your percentage profit figure, you do the following

Gross takings eg £100,000

minus the money spent on Purchases £30,000

gives a gross profit of £70,000

Divide the gross profit by the gross takings and times by 100 to get your percentage profit figure - 70,000 divided by £100,000 = 0.7 times by 100 = 70%
