According to Integra Information Systems industry profiles, general line grocery merchant wholesalers make a gross margin of 13.11 percent on average--so they have a markup of 15 percent. Those are wholesalers, also called distributors, who buy in volume and sell to retailers. A gross margin of 13.11 percent means what they buy for $86.89 they sell for $100, so the markup is calculated by dividing $13.11 by $86.89.
Grocery stores in general have even smaller markup. Their gross margin is 10.47 percent on average, so their markup is 12 percent.
