Restaurant profit margin by venue: food against beverage
What the answer looks like
Illustrative output on sample data
Illustrative example: how Lexi answers this for a restaurant group with eight venues. It joins 12 months of POS sales to recipe and supplier costs, split by food and beverage.
- Downtown venue: food $2.4M sales, $0.79M cost, 67% gross margin. Beverage $1.6M sales, $0.38M cost, 76%.
- Suburban venue: food $2.1M sales, $0.82M cost, 61%. Beverage $0.5M sales, $0.13M cost, 74%.
- Group: 66% on food, 75% on beverage.
What the data shows
Beverage earns the higher margin everywhere, but the suburban venue sells far less of it: 19% of sales, against 40% downtown.
What it means
The suburban venue has a food cost problem and a drinks gap. Food cost is 39% of sales there, five points over the group, mostly from portion sizes on two mains.
What to do
Check portions on the two mains and add a drinks pairing to the suburban dinner menu.
Food cost is only as accurate as your recipe costing. Would you like margin by menu item for the suburban venue?
Gross profit margin formula
Why it matters
A group-wide margin hides which venues and which side of the menu carry the profit. Splitting gross margin by venue and by food and beverage shows where costs are creeping, which venues lean on drinks to stay profitable, and where a menu or pricing change will move the bottom line most.
Frequently asked questions
What is a good restaurant profit margin?
Net margins are thin. The National Restaurant Association's 2025 Restaurant Operations Data Abstract reports median pre-tax income of 2.8% of sales for full-service restaurants and 4.0% for limited-service restaurants in 2024. Gross margin, before labor and overheads, runs far higher, so compare like with like.
Should food and beverage margins be reported separately?
Yes. Drinks usually carry a much lower cost of goods than food, so a venue's overall margin depends heavily on its sales mix. Reporting them separately shows whether a venue has a cost problem in the kitchen or simply sells fewer drinks than the rest of the group.
What data do I need to calculate gross margin by venue?
You need sales by venue from your point of sale (POS) system, split into food and beverage, and cost of goods for the same period from recipe costing or supplier invoices. Remove comps, staff meals and voids first, or the margin will look worse than it is.
