The average gross profit for convenience stores in 2009 was about $477,894. About 20 percent of convenience stores do not sell motor fuel that provides a gross profit margin of only about 6.4 percent.
Unlike profit, which gets measured in dollars and cents, profit margin gets measured as a percentage. To measure profit margin, use the companyâs net income divided by the total sales generated. For example, the furniture store had a net income of $100,000 and generated $500,000 in sales. To determine the store's profit margin, divide the net income ($100,000) by the total sales revenue ($500,000) and the store has a 20% profit marginâ$100,000/$500,000 = 0.20 or 20%. The profit margin also acts as a gauge of a companyâs control on operating costs.
